Make this Thanksgiving hands-on with our STEMs-Giving activities! Discover science, technology, engineering, and math through engaging Thanksgiving STEM lesson plans, ideal for both the classroom and home. From butter and bread to cranberries and potatoes, kids can discover the science behind their favorite holiday foods.
What Is STEMs-Giving?
STEMs-Giving is a playful way to blend Thanksgiving traditions with science and problem-solving. Each “menu item” is a hands-on experiment that connects to chemistry, biology, or physics. These activities encourage kids to observe like a scientist, experiment like an engineer, and think critically about the world around them.
Field of Science: Physical Science, Chemistry, Biology, Engineering
Grade Level: Kindergarten – 5th Grade
Concepts Explored:
- Chemical vs. physical changes
- States of matter
- Energy transfer
- Absorption and osmosis
- Engineering design process
- Scientific observation and measurement
Thanksgiving STEM Menu for Kids
This engaging Thanksgiving unit includes easy experiments, engineering challenges, and printable resources that spark curiosity while connecting learning to real-world traditions. Get ready for a feast of fun and discovery!
💡 We have more fun Thanksgiving Science and STEM activities, including free printables to explore.
Homemade Butter Science
Make butter in a jar! Kids shake heavy cream to see how physical changes happen through motion and temperature. A fun and tasty chemistry experiment.
Bread in a Bag Experiment
Discover how yeast makes bread rise through fermentation. A perfect way to demonstrate a chemical change while making a delicious treat to go with homemade butter.
Dancing Cranberries Experiment
Watch cranberries “dance” in carbonated water as carbon dioxide bubbles lift and drop them. A fun Thanksgiving science activity about gas, buoyancy, and states of matter.
💡Try an alternate dancing corn experiment with baking soda and vinegar.
Cranberry Secret Messages
Turn cranberry juice into invisible ink! Kids learn about acids and bases while writing hidden notes that appear with a chemical reaction. You can also create secret messages with invisible ink from lemon juice!
👉 Make Cranberry Secret Messages
Cranberry Oobleck
Mix cranberry sauce and cornstarch for a non-Newtonian fluid experiment that feels solid when you squeeze it but flows like a liquid. Another variation is pumpkin oobleck inside a real pumpkin!
Boiled Potato Chemistry
Test if cooking potatoes causes a physical or chemical change. Observe texture and form before and after heating—great for elementary science. The kids will also love this Potato Straw Experiment.
Answer: Cooking causes a chemical change—it can’t be reversed!
Supplies Needed: Note: Adult assistance is required for this activity.
- Raw potatoes
- Potato masher and fork
- Heat source (microwave, oven, or pot of boiling water)
💡 THINK ABOUT IT: What other popular Thanksgiving foods can you think of that go through a chemical change? How about a favorite pie or any of the side dishes on the table, including a berry that is red and tart!
Paper Bag Popcorn Science
Why does popcorn pop? Discover how heat turns water inside kernels to steam, creating pressure until it bursts open! A fun, quick Thanksgiving snack and science combo.
Potato Osmosis Experiment
See how water moves across membranes in this easy osmosis experiment using potatoes, salt, and water. Perfect for a biology tie-in.
👉 Try the Potato Osmosis Experiment
Corn Painting (STEAM Art)
Add art to your science! Paint with corn cobs or kernels to explore patterns, texture, and color mixing while learning about crops and harvests.
Potato Battery
Turn a potato into a working battery by creating a chemical reaction that produces electricity. A great introduction to energy and circuits. You can also make a pumpkin clock.
Pumpkin Pie Fractions Playdough Mats
Turn math into a sensory experience! Use our pumpkin pie playdough fraction mats with homemade pumpkin pie spice playdough to practice dividing pies into halves, thirds, and quarters.
👉 Get the Pumpkin Pie Fractions Playdough Mats and recipe.
Cranberry Structures (2D and 3D Shapes)
Build cranberry and toothpick shapes to explore geometry and engineering. Challenge students to design both 2D shapes (such as triangles and squares) and 3D structures (like cubes and pyramids) using printable shape cards.

Teaching Tips
- Spread the projects out over the week leading up to Thanksgiving break or during break.
- Pair each activity with a short journal reflection or NGSS question (see below).
- Encourage kids to make predictions and observe results.
- Integrate math by measuring ingredients, timing reactions, or graphing outcomes.
NGSS Connection Table
| NGSS Question | Concept Focus |
|---|---|
| How can materials change when we mix or heat them? | Chemical and physical changes in matter |
| How does heat affect solids, liquids, and gases? | States of matter and energy transfer |
| How can we use observations to describe patterns in nature? | Scientific observation and data collection |
| How do living things use energy? | Biology and food chemistry connections |
