## Science with Harry Potter: The Magic of Motion (Physics)

Charms is a core class and subject taught at both Hogwarts and  Ilvermorny Schools of Witchcraft and Wizardry. It is a required subject for all students. Throughout the course, students learn specific wand movements and proper pronunciation of the charms outlined in their course texts.

## Levitation

You don’t need a magic wand to create levitating objects. Simple gather a few things from around the house and you will be underway.

#### 1. Levitating Ping Pong Ball

You only need two things to perform this science experiment.

• Ping pong ball
• Drinking straw (preferably a bendy straw)

Procedure:

1. For the best results, use a bendy straw instead of a regular straight straw. Bend the neck 90 degrees so it points straight up. While holding the straw with one hand, hold the ping pong ball over the end.
2. Blow a constant breath of air into the straw under the ping pong ball.  If the air pressure is strong enough, it will lift the ball off the tip of the straw and the ball should be able to float at least one inch off the straw.

How does it work? Simply put, it’s air pressure.  The air coming from the straw is moving faster than the air around it, and this means that it also has a lower air pressure than the air around it.  The ball is kept within the column of lower air pressure because of the higher-pressure air surrounding it.

#### 2. Static Flyers

In this experiment, if you know how static electricity works, you can make the students at Hogwart’s envy your skills. Here’s a great TEDEd video to get you started, The Science of Static Electricity.

• Plastic produce bag
• Balloon
• Cotton towel

Procedure:

1. Use a pair of scissors to cut a strip from the open end of the produce bag. Once the strip is cut, you should have a large plastic band.
2. Blow up the balloon to its full size and tie off the opening end. Rub the the surface of the balloon for 1 minute with the cotton towel.
3. Flatten the plastic band on the table surface and gently rub the towel on the band for 1 minute.
4. Hold the plastic band about one foot over the balloon and let go. The plastic band should levitate.

How does it work?

Rubbing the towel against the balloon and the plastic band transfers a negative charge to both objects. The band floats above the balloon because the like charges repel one another. If you really want to impress someone, just tell them that it’s a demonstration of “electrostatic propulsion and the repulsion of like charge.”

In a related demonstration you may have tried picking up small pieces of paper confetti with a charged balloon. Though the paper isn’t charged, it is attracted to the balloon because the negative charge on the balloon repels the electrons in the paper, making them (on average) farther from the balloon’s charge than are the positive charges in the paper.

As something gets farther away, the electrical forces decrease in strength. Therefore, the attraction between the negatives and positives is stronger than the repulsion between the negatives and negatives. This leads to an overall attraction. The paper is said to have an induced charge.

#### 3. Levitating Spiral Orb

One more fun activity is the Levitating Orb. For this one, you’ll need:

• PVC Tube about 60cm long (a regular balloon will also work)
• Mylar tinsel (typically used to decorate Christmas trees)
• Cotton towel (or your clean hair)
1. Arrange 6 strands of mylar together and tie them together in a knot at one end. Do the same at the opposite end (each knot should be about 15 cm apart). Cut off any excess strands on the ends that protrude beyond the knot.
2. Charge the PVC tube by rubbing the towel back and forth along the length of the tube for about 30 seconds.
3. Hold the mylar orb (by the knot) above the charged tube and let it drop and touch the tube.
4. It should repel away and start floating. If the tinsel keeps sticking to the tube, the tinsel is probably not thin enough and you will need to try another kind of tinsel. You will also need to “recharge” the tube each time.

## Projectile Motion

In the Harry Potter movie The Sorcerer’s Stone, Malfoy throws Neville’s remembrall and Harry races after it, making a spectacular catch (all while flying on broomsticks).

Magical Motion ~ Using this film as a starting point, students are immersed in concepts related to projectile motion. They explore the relationships between displacement, velocity, and acceleration.

Projectile Magic ~ In the next lesson, they learn to use equations of linear motion to describe the behavior of a system as a function of time.

## Alchemy

Alchemy is an elective taught at Hogwarts School of Witchcraft and Wizardry concerning the study of the four basic elements, as well as the study of the transmutation of substances. It is intimately connected with potion-making and chemistry but for purposes of clarity, this post will focus on transformation of rocks and minerals.

I’m particularly interested in Transfiguration, you know, turning something into something else, of course, it’s supposed to be very difficult.” —Hermione Granger regarding transformation

There are many myths and legends about the formation of the rocks of the Earth or about the rocks themselves. Every culture has its own beliefs about specific stones and those beliefs are often tied to that culture’s history, geography, and spiritual practices.

For this class students are required to become familiar with the many magical properties of common stones. Begin by writing the definitions for igneous, metamorphic, and sedimentary rock in a notebook. Include a detailed sketch of the rock cycle.

Additionally, create a two-page spread for each stone studied. Include the following information for each:

1. photo or sketch
2. list any historical or literary references to the gemstone
3. describe the process by which it is formed
4. list its magical properties

Some stones to consider are:

• Agate
• Quartz
• Ruby
• Opal
• Flint
• Moonstone
• Obsidian

Put together a collection of rocks and minerals. Identify and label each as igneous, metamorphic, or sedimentary.

### Take it Further

Learn to play Marbles, generally a Muggle game. Wizards play a variant known as Gobstones, where the enchanted marbles spit a putrid fluid into the face of the loser.

## Astronomy & Divination

At Hogwart’s, Divination is an elective course that teaches methods of divining the future, or gathering insights into future events, through various rituals and tools. For the purposes of this course, we will focus on the ancient tools used by early navigators particularly in regards to the study of astronomy.

Generally out-of-bounds except for classes, the Astronomy Tower is the tallest tower at Hogwarts Castle. It is where students study the stars and planets through their telescopes with Professor Aurora Sinistra.

A Star chart is a written document used to represent the positions and movements of the stars, much like a map. Astronomers usually use these for research or study. An O.W.L. level wizard should be able of fill in a blank star chart based on some hours of sky gazing.

Similarly, a Moon chart is used to represent the position, movement and phases of the Moon. However, it is difficult to interpret and thus a Lunascope is often preferred.

Begin by researching the constellations common in your hemisphere and/or those referenced in the books.

Illustrate each cluster of stars in your notebook and make note of when the constellation was first discovered and how it was named. Include the names of the distinct stars (if possible).  Constellations to consider include:

• Orion
• Bartholomeus
• Lupus
• Leo
• Ophiuchus
• Canis Major
• Scorpius

Create personal chart (also referred to as a birth chart) showing the relative positions of the planets at the time of an individual’s birth.

If possible, obtain a telescope with which you can observe the planets and distant stars.

### Take it Further

Create a model of our solar system. Include the moons of Jupiter, Saturn, and other major planets.

Make an illustrated wall timeline of geologic time.

Draw maps of the earth at various times in history, showing movements of the tectonic plates. Include time periods that show Pangaea, Laurasia and Gondwanaland, and the modern arrangement of continents.

Illustrate the layers of the atmosphere in a poster. Label and describe each layer.

## Science with Harry Potter: Potions (Chemistry)

Potions have always been essential in magic. Stories of witches tell of brewing magical drinks that turn men into mindless animals, restore youth, and make the drinker invisible. Other potions caused false emotion to be created such as when Ron Weasley declares his Love Potion-induced feelings for Romilda Vane.

I don’t expect many of you to appreciate the subtle science and exact art that is potion-making… I can teach you how to bewitch the mind and ensnare the senses. I can tell you how to bottle fame, brew glory, and even put a stopper in death.” ~ Professor Severus Snape

First year students will learn many skills that will be important for potion making. Advanced students will apply these skills to the development of a Marauder’s map and wizard wands.

A wizard or witch who specializes in potion brewing is known as a potioneer or a potions master.

In this course, students are expected to keep a journal to record what has been done (including ingredients, procedures, spells, chants, etc) and reflect upon what was learned.

Print a periodic table of the elements and put it into your notebook. On the facing page sketch out elements 1-10, use color-coding for protons, neutrons, and electrons.

## Potions

Knowledge of potions and charms is a powerful weapon against dark forces. Learn about ions, ionic and covalent bonds, and compounds. Write the definitions in your notebook.

Prepare each of the potions described below and record your observations. Illustrate as desired.

### Potion 1: Goblin Slobber

Goblin slobber is a potion which is particularly effective against being followed through woods and caves. Just drip some goblin slobber on the path behind you and anything that is chasing you will be driven away.

• One flask of water
• ¼ measure instant goblin slobber(dehydrated)
• 1 full measure Manticore milk
• 1 full measure water
• 3 drops goblin blood

Cauldron (mixing bowl will do if you have not yet received your cauldron)

1. Rehydrate the goblin slobber:Pour the instant goblin slobber into the flask of water. Stir briskly with wand to dissolve while chanting “soluloso aqualitem.” Repeat until fully dissolved.

2. Into the manticore milk pour the measure of water and the goblin blood and stir, repeating incantation.

3. The final step is to pour the two solutions into the cauldron and stir well chanting “goblinatum sloberosum.” You may need to adjust the quantities, so add them slowly.

### Potion 2: Muggle Paper

This bright yellow potion gives you the ability to detect whether someone is muggle or magic.

• 1 vial nettle nectar
• 1/4 vial (approx) ground dragon scale
• filter paper
• Veritaserum

1. Put your filter paper into the cauldron.

2. Dissolve the ground dragon scale into the nettle nectar, shaking well to dissolve.

3. Pour over top of paper, allowing it to soak in well.

4. Remove paper from cauldron and hang to dry. Dust off any left over dragon scale.

5. Once paper is dry, dip right hand into Veritaserum (pour it into a bowl) and place directly onto paper with a slap.

6. Your true bloodline will be revealed!

### Potion 3: Instant Ocean

This potion is very useful for creating a peaceful seaside vacation atmosphere in a small space. If made properly you can see the tiny waves and sea-foam inside the flask. This potion should be done in a place where messes are not a problem in case of sloppy magic by first year students. A calming charm may be needed in case of storms at sea.

• 2 vials Midsummer Dewdrops
• 1/2 dribble Kraken slime
• 3-4 drops of Squeaking-Squid ink
• 1 teaspoon Pulverized Narwhal Horn dissolved in ~2 tablespoons very warm water
• Funnel
• Large Cauldron

1. Stand flask in cauldron with funnel in top

2. Add 3-4 drops of squid ink to the Midsummer dew, shake well to mix

3. pour through the funnel into the flask

4. Add the Kraken slime to the mixture in the flask.

5. Pour the narwhal horn mixture into the bottle and remove the funnel.

## Marauder’s Map

In the film Harry Potter and the Prisoner of Azkaban, what first appears to be a blank piece of parchment becomes a magical Marauder’s Map. In this lesson, students create their own invisible inks, they learn what acids, bases and indicators are and how they can be used.

Begin by drawing a pH scale in your notebook. Use your “muggle” paper (created with Potion 2) to test a variety of substances around the house (vinegar, wine, lemon juice, baking soda, cola, bleach, ammonia, milk, etc). Make a table in your notebook showing your results. If you have litmus papers you can use them as well.

With your knowledge of acids and bases, create a map of your own using an ink you have devised.

## Wizard Wands

Wands have been mentioned throughout time. Popular fantasy stories from a variety of origins have featured characters using wands. It could thereby be reasoned that Ollivander’s (makers of fine wands since 382 B.C.) had provided them.

To begin, learn about molecules and sketch several in your notebook (water, carbon dioxide, methane, glucose, etc.) Consider making models with gum drops or balls of clay and toothpicks.

There will be no foolish wand-waving or silly incantations in this class. ” ~ Professor Snape on Potions class

Explosive Enterprises is a line of fireworks sold at Weasleys’ Wizard Wheezes. This group of fireworks included the original Weasleys’ Wildfire Whiz-Bangs as well as a variety of new and creative pyrotechnic products created by Fred Weasley and his twin brother George.

## Science with Harry Potter: Care of Magical Creatures (Zoology)

Care of Magical Creatures is an elective at Hogwarts, available to upper classmen. Throughout the course, students learn about a wide range of magical creatures and are taught about the care and husbandry.

Similar to herbology, the further into a student’s education the more difficult and dangerous the creatures become. The witches and wizards who succeed in the subject later become Magizoologists, like Newt Scamander.

For this class students are required to become familiar with the many magical creatures you may encounter both at Hogwarts and in the outside world. Students should begin with the following:

• Owl
• Hippogriff
• Phoenix
• Unicorn
• Werewolf
• Centaur
• Basilisk
• Elf

C’mon, now, get a move on! Got a real treat for yeh today! Great lesson comon’ up! Everyone here? Right, follow me!” ~ Rubeus Hagrid at his first Care of Magical Creatures lesson

Students are required to keep a field notebook in which a two-page spread is created for each magical creature studied. For each magical creature you study:

1. Make a sketch of the creature, labeling important features
2. List any historical or literary references to the creature
3. Describe its natural habitat
4. Discuss its habits, temperament, and relationship to humans
5. List its magical properties
6. Explain the care and feeding of the creature

Advanced students may choose additional magical creatures to study. Take care to choose wisely, as your knowledge of magical creatures could one day prevent a terrible injury or death.

### Magical Properties of Dragons

You’ve likely already discovered the magical property of dragon scales while researching and preparing your field notes above. Now you will learn about the properties of dragon skin and dragon down (the fluffy feathers from underneath the wing).

Young wizards and witches should have adult supervision as all parts of a dragon are highly flammable. A fire-proof cauldron is advised.

Dragon Skin: take thin slices of dragon skin and hold them next to an open flame. Bend the skin, squeezing until it bursts. You should see tiny sparks fly as the fire-breathing properties are released. This should be done very close to the flame.

Dragon Down: Put a small quantity of dragon down into a cauldron. Touch the end of a 9 volt battery lightly to the down to release the fire-breathing properties.

### Genetics

Students watch a video clip from Harry Potter and the Goblet of Fire to learn about genetic traits. Specifically, they realize that the ability to speak parseltongue (being able to speak to snakes) is a genetic trait possessed by some characters and their parents. Students explore the use of Punnett squares to predict trait inheritance, learning about genotypes and phenotypes.

## Science with Harry Potter: Herbology – The study of plants and fungi (Botany)

Herbology is the study of magical and mundane plants and fungi. It is a core class and subject taught at Hogwarts School of Witchcraft and Wizardry for the first five years of a student’s education.

## Herbology

Throughout each term, students learn to care for plants as well as learn about their magical properties and how they may be used medicinally. The further into a student’s education the more difficult and dangerous the plants become.

“Three times a week they went out to the greenhouses behind the castle to study Herbology, with a dumpy little witch called Professor Sprout, where they learned how to take care of strange plants and fungi, and found out what they were used for.” ~ Harry Potter and the Sorcerer’s Stone

All first year students are required to familiarize themselves with the herbs listed below.

• Chamomile
• Tarragon
• Yarrow
• Caraway
• Dill
• Aloe Vera
• Silver Birch
• Garlic
• Tumeric

As students work through their self-guided journey, they are required to keep a field notebook in which a two-page spread is created for each plant or fungi studied. Each spread is required to include the following information:

1. Give common name as well as Latin names (genus and species) and family
2. Press a specimen of the plant (if possible)
3. Make a sketch of the plant, colored appropriately
4. Label key parts of the plant, pointing out important features
5. Explain its cultivation and care
6. Give a brief natural history of the plant (describe growth cycle, natural range, etc.)
7. List its household and medicinal uses both presently and historically
8. Describe its magical properties (if any)

### Take it Further

Enjoy a cup of Chamomile tea before bedtime or a glass of birch beer with your noonday meal.

Explore the many wildcrafting and herbal remedies described at Learning Herbs.

Enjoy the fun board game, Wildcraft: An Herbal Adventure.

Research the native plants in your local area and learn how native peoples used them for food and medicine.

Visit a native elder, if possible, and learn to how to harvest and prepare these plants for personal use.

As you advance in your studies, be sure to add each new plant to your journal.

## Finding Harry Potter at the MET with Watson Adventures

We rejoiced when Harry Potter and the Cursed Child arrived at our doorstep last month. We had been following the opening of the two-part play in England on social media and anxiously awaited the ne book to be released here in the states on July 31st, Harry Potter’s Birthday.

Anytime we come to the final chapter of a beloved book, we are a little remorseful to say goodbye to our favorite characters. We wanted to continue living in the magical world so beautifully imagined by JK Rowling.

###### I was provided tickets in exchange for an honest review; please see my disclosure policy for details.

I first learned of Watson Adventures while in San Francisco years ago for Chinese New Year. We had observed several small groups of people racing through Chinatown on an unique scavenger hunt, seeking answers to thoughtful trivia questions. Watching their enthusiasm and hearing their high praise, I tucked the little bit of information away. I knew this was something I wanted to experience.

While planning our itinerary for our East coast holiday, I took a peak at the Watson Adventures website I had earlier pinned to a Pinterest board. Much to my delight, a public scavenger hunt was available during our stay in New York City. There were many hunts to choose from, the difficultly was choosing.

A few of the many Watson Adventures Public Scavenger Hunts in New York:

## Harry Potter & The Wizard School Scavenger Hunt

When I glimpsed the title, The Wizard School Scavenger Hunt, I knew immediately this was the experience for us. This scavenger hunt would provide us the opportunity to follow in the footsteps of young wizards on a field trip to the Metropolitan Museum of Art in search of works that echo characters, places, and enchanted objects in the famed Harry Potter books and movies. What better way to celebrate, share in the love of the book, and discover the Met?!

The Wizard School Scavenger Hunt is designed for kids and adults to do together, but all-adult teams are allowed to compete separately. Kids must be accompanied by adults. For ages 10 and up.

We joined the The Wizard School Scavenger Hunt on September 17th at the MET in New York City. There were several others teams – both family and adult teams – competing. Two family teams were taking part as a birthday celebration for one of the young participants. We were encouraged to come up with creative team names and the most creative team was awarded bonus points.

I was very impressed with how well Michael and his assistant Shannon organized the teams and explained everything. There were only a few rules – essentially: No running. Teams must stay together. Don’t touch the art. We were given 90 minutes to complete the 24 question quest and we were off!

Fortunately, each team was assigned a different question with which to start. When we did meet other teams along the course, tensions rose. “Oh no! They are catching up with us. We have to hurry!”

Their scavenger hunts use witty, tricky questions in fast-paced games that bring out the best in a fascinating place—and the best in you and your teammates. The hunts are like walking tours spiked with caffeine.

Racing against other family teams, we hunted through the MET for Hagrid-like giants, centaurs, and unicorns that would feel at home in the Forbidden Forest. References to the books provided a surprising bridge to many strange and wonderful works of art. The Cursed Child provided us with new hints and tidbits. Not to worry, there were no spoilers!

The questions weren’t easy, however. One point was awarded for each correct answer (no points off for wrong answers). The team with the highest score wins! There was strong competition and amongst the five family teams competing, the scores ranged from 18-22. We didn’t win the coveted Watson Adventure medal (shown here with the winning family team) but we had a fabulous time. We all agreed we would love to take part in another if we ever get the chance. It was certainly a highlight of our trip.

## Tell Me More About Watson Adventures

Bret Watson started creating scavenger hunts in the early ’90s as a way to share his unique take on the lighter side of museums with his friends. Word began to spread and it wasn’t long before Watson Adventures sprung to life.The scavenger hunts are open to the general public on weekends and are available in seven cities:

• Boston
• Chicago
• Los Angeles
• New York City
