Nature Journaling in the Classroom

Many homeschool families engage in regular nature studies.  A nature journal is your ticket to a deep exploration of the world around you, providing a place to record your encounters with the natural world — from the everyday to the sublime. Field sketches, regardless of the degree of artistic talent with which they are rendered, force us to look closely and observe nature as it really is. Simply put, nature journaling is the regular recording of observations, perceptions, and feelings about the natural world around you.

nature journaling

The past couple of years, I have been teaching an online course, Nature Journaling in the Classroom.  It is designed to help teachers and informal educators integrate nature journaling into their K-12 art and science curriculum.  The course is offered through the Heritage Institute and optional, university credit is available.

J.L. Fottrell, a geologist who teaches drawing classes at Land Between the Lakes National recreation area in Tennessee/Kentucky and at Bowie Park in Fairview, Tennessee, recently selected my course because he had never made a systematic, concerted effort to study nature journaling.


Fottrell had this to say about his expectations at the conclusion of the course, “I expected to learn some techniques and methods for teaching the subject in a more organized, school setting.  What I learned   was what I expected to learn plus a lot more.  The reading assignments were full of good ideas and much of it was thought provoking and insightful.  I feel that I got a lot more out of the books than I expected.  The other exercises … pushed me beyond where I was, in my understanding of the subject.  I believe that I’m much better educated about nature than I would have been, had I not taken the course.”

H. Lent, a teacher in Oregon, recently took my course along with another I teach, Alien Invaders.  She spends her day between the High School, where she teaches algebra and the Middle School where she teaches 8th grade math, MAN (Math, Art, & Nature), and two art classes.  I love how she morphed the two courses together and devised a year-long study of invasive species, integrating math, science and art.

Upon completing the coursework, Lent shared with me, “I did not realize that nature journaling was such a powerful tool in life and can be integrated into any curriculum and any grade level. The sooner the better obviously to train kids and make it a life-long endeavor.  I learned the important items to include in the journal daily: how to label; to include date, place, weather, colors, feelings. Drawings and/or writing are each valuable and students can develop their own style to document their observations.”


What is Science? – Transitioning to Inquiry Based Instruction

Over the past few weeks I have been sharing with you a series of posts that address the scientific method, science process skills, and science as inquiry. Inquiry-based instruction often represents a new and complex classroom situation for teachers and students. Both need the time to gradually make a transition from the more classical type activities and lectures, to more open-ended activities characteristic of inquiry-based instruction.  Today, I share with you examples of how to easily modify existing cook-book activities for a more inquiry based instructional approach.

what is scienceA good place to start is to conceal the title of the activity.  Frequently the title of an activity can give away the instructional objective and students are thereby easily able to guess at an appropriate hypothesis.  Another suggestion is to remove premade data tables that accompany many lab activities. Have students figure out for themselves what data to record, and how to record it. While students may struggle and need assistance in the beginning, with continued practice they will find success.

Once students are comfortable recording their own data, educators can move on to further activity modifications. For example, parts of the procedures can be deleted. Students make decisions that can have small effects on the outcomes of the activities, while still using the materials the teacher had planned on using. Teachers can also experiment with having activities come before lectures (or direct instruction). This simple change can provide many wonderful opportunities for learning opportunities and discussions.

Example of a Classic “Hands-on” Science Activity

Make an Egg Float in Salt Water

An egg sinks to the bottom if you drop it into a glass of ordinary drinking water but what happens if you add salt? The results are very interesting and can teach you some fun facts about density.

What you’ll need:

  • One egg
  • Water
  • Salt
  • A tall drinking glass


  1. Pour water into the glass until it is about half full.
  2. Stir in lots of salt (about 6 tablespoons).
  3. Carefully pour in plain water until the glass is nearly full (be careful to not disturb or mix the salty water with the plain water).
  4. Gently lower the egg into the water and watch what happens.

What’s happening?

Salt water is denser than ordinary tap water, the denser the liquid the easier it is for an object to float in it. When you lower the egg into the liquid it drops through the normal tap water until it reaches the salty water, at this point the water is dense enough for the egg to float. If you were careful when you added the tap water to the salt water, they will not have mixed, enabling the egg to amazingly float in the middle of the glass.

Tweak it for Inquiry Based Instruction

Walking through the above activity step by step as described is a cook-book approach and while the child may find it interesting, there is little thinking involved.   Instead hand the student an egg and present them with an open-ended challenge, “I bet you can’t get this egg to float on water.”  Allow the child to work through their own ideas and solutions, offering suggestions or hints if necessary.

Science at Home – Air Has Mass

I’m excited to participate in my first Google+ event … Science at Home.  This month, the topic is Air and I have put together two activities that I know you will enjoy, both of which I have used with my own kiddos.  The focus of the demonstrations is to show that air has mass.  When doing these activities with your children, however, try not to reveal the objective of the demonstration.

Allow students to observe the process without knowing the outcome.  This will help them to write their own title and objectives. Instead of standard after-lab-questions, ask students to complete the missing title and objectives. It is a fun twist and makes the lab more creative and inquiry based.

Science at Home HOA2

Air is the sea of particles in which we live. Wrapped around us like a blanket, students sometimes mistake air as being without mass or weight. I shared two science demonstrations today to prove to students that air does indeed have mass.  

Air Has Mass

In the first activity, two balloons filled with air, will be used to create a balance.  Inflate the two balloons until they are equal in size and tie them off. Attach a piece of string to each balloon. Then, attach the other end of each of the strings to the opposite ends of the meter stick, keeping the balloons the same distance from the end. The balloons will now be able to dangle below the ruler.

Tie the third string to the middle of the meter stick and hang it from the edge of a table or support rod. Adjust the middle string until you find the balance point where the meter stick is parallel to the floor. Once the balance scale set-up is completed, the experiment can begin.

As the kids sketch the set-up, ask them to predict or make an hypothesis about what will happen if you were to poke a hole in one balloon.  Do so and encourage them to record their observations in words or pictures in their journal.

The balloon that remains full of air will cause the ruler to tip showing that the air has weight. The empty balloon’s air escapes into the surrounding room and is no longer contained within the balloon. The compressed air in the balloon has a greater weight than the surrounding air. While the weight itself cannot be measured in this way, the experiment gives indirect evidence that air has mass.

CO2 is Heavier than Air

Another fun demonstration you can do easily at home illustrates that carbon dioxide gas is heavier than air. It takes a little practice but once you’ve got it down it’s pretty fun!  You’ll need two glasses, baking soda, vinegar, and a small candle.  Measure a tablespoon of baking soda into one glass.  Light the candle.  Measure a tablespoon of vinegar and pour it into the glass with the baking soda.  Allow it to bubble for a moment and generate the carbon dioxide gas.  Depending upon the size of your glass, it may bubble over.  No worries.

When the bubbles have receded a little, carefully lift the glass and pour the carbon dioxide gas into the second glass.  Be careful not to pour the liquid; you won’t actually see anything pour – but trust me.  Then, gently lift the second glass (which appears to be empty) and pour it over the burning flame. In just a few seconds, the flame will be extinguished.

In order to burn, fire requires oxygen. Fires start when a flammable material, in combination with a sufficient amount of oxygen gas (or another oxygen-rich compound), is exposed to a source of heat, and is able to sustain a rate of rapid oxidation that produces a chain reaction (the fire tetrahedron).  Fire cannot exist without all of these elements in place and in the right proportions.  When the carbon dioxide gas is poured from the glass, gravity pulls it down and it pushes the oxygen rich air away.  Without oxygen, the flame is extinguished.

Take it Further

Can you find ways to test the mass of different gases?  How could you compare the mass of helium and carbon dioxide?  What can the periodic table tell you about these elements?

In addition to two activities I shared in the hangout today, I also did a few other simple activities with my kiddos which I have described in more detail in an earlier post, Air Pressure and Wind Activities.

The Secret of the Tides

I grew up in Bandon, Oregon and though we now live in the valley of northern California, we travel home as often as possible.  While we go primarily to see family, the ocean pulls us to her just as compellingly.  We have enjoyed exploring the tide pools, investigating the unique estuarine habitats, and tasted freshly caught Dungeness crab many times in the past.  Recently, however, we spent some time taking a closer look and discovering the secret of the tides.

tidal chart

As pictured in the the photo collage above, we visited a beach access area at both low tide (6:59 a.m. @ -1.9′) and high tide (6:56 p.m. @ 1.5′).  I specifically selected this area because on low tide, we had access to tide pools.  Shortly after I took the photo, we walked down the stairway and spent time investigating the marine invertebrates.  While we marveled at the sea stars and innumerable sea anemones, I began to pose questions about the animals we observed and about the wave evidence on the shoreline.  We noted specifically where we found each species and shared our hypothesis for how these organisms could survive in such a dramatically changing environment. I’ll share our discoveries soon – the kids are still working on their nature journals.

Create a Tide Graph

One of the most useful activities we undertook this past week was to create a tide graph and then use the newspaper to also plot the corresponding moon phases.  To create a tide graph yourself, use a tide chart and select a specific month; you can access tidal data from NOAA.  Use a piece of graph paper to  graph the highest high tide and the lowest low tide for each day (recall there are typically two high tides and two low tides each day).  Use a different colored pencil for each tide type.  The day of the month should be on the x-axis and the height of the tide on the y-axis.  Tides can be negative, so be sure to include negative numbers on your y-axis.

Lastly, find a moon phase calendar for the selected month (or look up the moon phase in your local newspaper).  Sketch the four major moon phases (new moon, 1st quarter moon, full moon, and 3rd quarter moon) under the corresponding calendar date and label them accordingly.  After completing the graph, answer the questions listed below.

  • Is there a relationship between the phase of the moon and the tides?  Explain what you observed based upon your graph.
  • What are spring tides? Based upon your data, around what phase(s) of the moon do spring tides occur?  How do you know this?
  • What are neap tides? Based upon your data, around what phase(s) of the moon do neap tides occur?  How do you know this?

** Please note that graphs will vary depending upon the selected location and time of year.  A great extension activity is to create tide graphs for distinctly different locations (Newport, Oregon and Cape Code, Massachusetts, for example) and/or different seasons.

What is Science? – The Importance of Inquiry

Earlier this month I shared with you my view that science is an exciting and dynamic process of discovery.  Today, I expand upon that definition to explore the importance of inquiry, specifically scientific inquiry.  The National Science Education Standards (NSES p. 23) defines scientific inquiry as “the diverse ways in which scientists study the natural world and propose explanations based on the evidence derived from their work. Scientific inquiry also refers to the  activities through which students develop knowledge and understanding of scientific ideas, as well as an understanding of how scientists study the natural world.”

what is science

Unfortunately, our traditional educational system has worked in a way that discourages the natural process of inquiry. Students become less prone to ask questions as they move through the grade levels. In traditional schools, students learn not to ask too many questions, instead to listen and repeat the expected answers.

In many classrooms and homeschool families, students enjoy fun science lessons that feature hands-on projects and activities that help bring the exciting world of science to life.  Unfortunately, many of these science experiences are canned lessons that do not require them to apply their skills and understanding of the scientific concepts.  Frequently, the experiments are laid out for them including the title, question, materials, and procedures.  While these technically “hands-on” activities are essential, they are not enough.  Students must also have “minds-on” experiences as well. Science is an active process, learning science is something that students should do, not something that is done to them.

Success in science is more than “science as process,” in which students learn such skills as observing, inferring, and experimenting.  Inquiry is central to science learning. When engaging in inquiry, students describe objects and events, ask questions, construct explanations, test those explanations against current scientific knowledge, and communicate their ideas to others. They identify their assumptions, use critical and logical thinking, and consider alternative explanations. In this way, students actively develop their understanding of science by combining scientific knowledge with reasoning and thinking skills.

importance of inquiry

The importance of inquiry does not imply that teachers should pursue a single approach to teaching science, nor a single curricula. Just as inquiry has many different facets, so teachers and home educators need to use many different strategies to develop their students’ understandings and abilities. The content can be organized and presented with many different emphases and perspectives in many different curricula.

Join me again in two weeks when I share with you examples of how to easily modify canned science activities to create inquiry based experiences.  I will provide examples of how teachers can move their classical instruction to an inquiry-based instructional approach.
