Hands-On Projects for Teaching the Body Systems

Mon, 01 Jun 2026 22:44:45 GMT

There are so many activities for teaching the body systems, however it seems like many of the activities are too simple and only really involve students labeling the parts. We’ve developed several hands-on activities that push students thinking and ensure they are learning the importance of these body systems and how they work together to keep us healthy.

Body Systems Poster

One of our favorite activities for students is drawing the body systems on butcher paper. We have them draw it on these large sheets of paper so that they can draw a life sized image. They love getting to use such a large piece of paper and tracing their own body on it. Many groups just have their body standing in a neutral position but some groups step it up to make their body show off muscles or other funny poses. This type of project engages all students!

This project usually starts with students:

1) Tracing their body and using it to draw the __________ system.

2) Then labeling the organs they have learned about.

While students are thrilled to just draw and label their body system - that usually isn't very rigorous. So here are some ideas to increase the rigor and help students make connections to real life. They can write their responses to these questions on the blank space around their drawn body.

Teaching Students about the Skin

Teach students about the skin by having them make a model with snacks! We used crispy marshmallow squares to represent the fat under the skin. Peanut butter represented the actual skin. Green jelly beans were used to represent the germs that are on our skin at all times.

Students will:

Spread 1-2 Tbs of peanut butter on top of the marshmallow square.
Place 2-3 green jelly beans on top of the peanut butter.

We also used blue and yellow jelly beans. Blue jelly beans represent the sweat we give off when our body is hot. Yellow jelly beans represent the sun's rays that hit our skin when we are outside.

You can even let students use the skin color of their choice by letting them use cookie butter, frosting or Hazelnut spread instead (be aware Hazelnut spread is made from nuts)!

We know students will be excited to eat this project so make sure you snap a few pictures to share with families before your students dive in!

Extension Questions

Explain how your model represents the skin and how it protects us.
What would happen if our skin was not there?
How accurate do you think this model is compared to real human skin?

Building a Hand to Teach about the Musculoskeletal System

This next project might look hard but it’s actually very easy! With this project students will build a human hand to demonstrate their understanding of how the muscular and skeletal systems work together.

Material

White Cardstock (1 sheet per student)
Smoothie Straws * (3 per student) (regular straws work too but it's harder to get the string inside)
Twine or string
Hot Glue

Extension Questions

What do the straws and string represent?
How is this model similar to a real hand?
How is this model different from a real hand?
How do bones and muscles work together to move the fingers?
If you had to redesign this model, what would you change? Why?

Meaningful Test Corrections for All Learners

Mon, 01 Jun 2026 00:23:33 GMT

Test corrections have been around for a long time. They can be very meaningful for some students. But for students who scored very low, completing test corrections can be overwhelming and not help them learn the content better. Students who get a perfect score are missing out on an opportunity to reflect on their thinking. Regardless of their score, all students need to be met where they are. When I do test corrections, students complete different test correction activities depending on their test score.

Level 1

Any student who scored below a 50%, likely has some large gaps in their understanding of this topic. For this group, they are going to need the most support. I assign these students to work with an adult (usually myself but a TA or lead teacher can help too). With the help of an adult they look for clues on the test and consider any important information they have learned that might apply to this question. I often let them use their notes as well. This activity allows students to focus on relearning specific skills they didn't understand the first time.

Level 2

These students scored somewhere between a 50% and 80%. They have a basic level of understanding of the topic but often just have a few misconceptions or were just tricked by some of the questions. They focus on reflecting on their original answer and making sense of a new answer. They can work independently or in a partnership. This activity helps students identify gaps in understanding and recognize patterns in their mistakes.

Level 3

Any student who scored above a 80%, likely won't beneift much from completing typical test corrections. For this group, they choose 5 questions from their assessment that they got correct. They will rank the answers from most correct to least correct and provide a justification for their rankings. This activity pushes students beyond simple recall and towards deeper reasoning.

So after your next assessment give this a try and see if your students benefit from it too! Discover more ideas, classroom tips, and teaching strategies in the Coffee and Sneakers blog !

Hands-On Plants and Soil Activities for Kids

Sat, 30 May 2026 19:39:24 GMT

Not every classroom has access to garden beds, grow lights or other things needed to teach students about plants and soil. We have developed several investigations to help students understand how plants grow and survive while using minimal materials.

Sunlight, Water & Plant Space Investigation

Have students plant a radish seed in three different pots. Radish seeds work well because they are quick to spout and harvest. One pot will receive no shade (full sun), another pot will have part shade (sunlight for a few hours a day), and the final pot will be in full shade (no sunlight). We used this indoor potting soil * for our investigation. If you plan to bring these in the classroom you might want to consider getting indoor soil as soil made for outdoor use often attracts tiny black bugs which multiply quickly. We had zero bug issues with this soil. We also used these pots * and found they were the perfect size for this investigation.

To investigate how plants need water, you will setup the investigation the same way: 3 pots each with a radish seed planted in them. We used these brand of radish seed * for all the investigations because we have always had good luck with germination rates from this brand. This time the sunlight must remain the same for all three pots. However, one pot will get a typical watering amount each day. One pot will get significantly more water than the others . Finally the last pot will get no water. Students will quickly see that with no water the seed will not even germinate and with too much water it can lead to root rot and an unhealthy plant.

Finally, if you want to show students to see the importance of plant space setup your investigation with the same 3 pots. The sunlight and water must remain the same, but this time the number of seeds we plant will differ. The first pot will only have 1 seed, the second pot will have 5 seeds and the final pot will have 10 seeds. Students will quickly see that when seedlings have to fight for space they will not grow as much as if they would with adequate space.

Plant Life Cycle Investigation

For this investigation we used lima bean seeds * from the same brand as the radish seeds. The key to this investigation is to soak the lima beans in water overnight. Then place the seed in a wet paper towel and place in a zip top bag that is taped to a sunny window. Students should check on it daily or every other day to ensure the paper towel stays wet.

Soil Investigation

When teaching students about soil types it would be best to use the actual resources: sand, silt and clay. While it's not impossible to get a hold of those materials, it can be challenging. You can try to find soil kits online, but they are difficult to find and usually pricey. You may be able to find these items at your local cooperative extension office or you can get these items straight from the source: sand from playgrounds, silt from riverbeds and clay in some garden beds. However since none of those options are very convinent we have designed a lesson that uses regular house hold items instead to simulate those three items.
