Apple Science Experiments for Kids
Apples are perfect for easy fall science! With just a few simple supplies, kids can explore chemical reactions, oxidation, gravity, buoyancy, observation, and the apple life cycle.
Try one of these apple science experiments on its own, or combine several for an easy apple science week at home or in the classroom.
Fields: Life Science, Chemistry, Physics
Grades: Preschool–Elementary
Concepts: Observation, oxidation, chemical reactions, gravity, buoyancy, life cycles
Best Apple Science Experiments
These apple science activities are easy to set up and cover a mix of chemistry, physics, and life science concepts.
Erupting Apple Volcano
Turn an apple into a simple chemistry investigation with baking soda and vinegar. Kids can observe the bubbling reaction and discuss what happens when an acid and a base combine.
Why Do Apples Turn Brown?
Why does a cut apple change color? Use this classic apple experiment to explore oxidation and test ways to slow browning. It’s a great activity for making predictions and comparing results.
Apple 5 Senses Activity
Use apples to practice careful observation with all five senses. Compare apple varieties by looking at color, texture, smell, sound, and taste.
Apple Observation Activity
Turn one apple into a simple science investigation. Kids can use the five senses, compare the inside and outside, count seeds, measure, make a sink-or-float prediction, and record what they notice.
How Does an Apple Grow?
Explore how an apple grows and learn about the parts of an apple with this hands-on life science activity.
Apple Life Cycle
Follow an apple from seed to tree to fruit. This is an easy way to connect fall learning with plant life cycles.
Apple Gravity Experiment
Explore gravity and motion by racing apples. Kids can make predictions, observe movement, and compare results.
Balancing Apples
Experiment with real and paper apples while exploring gravity, balance, and stability.
Apple Oobleck
Make apple-themed oobleck and explore a material that behaves differently depending on how you handle it.
Red Apple Slime
Give slime a fall twist while exploring polymers and the properties of a stretchy, non-Newtonian material.
Do Apples Float?
Predict whether an apple will float before placing it in water. Use the results to start a conversation about density and why some objects float even when they feel heavy.
Plan an Apple Science Week
Want to turn apple season into a simple week of hands-on science? Choose one investigation each day.
Monday — Observe: Apple 5 Senses Activity
Practice making observations and comparing apple varieties.
Tuesday — Investigate Change: Why Do Apples Turn Brown?
Explore oxidation and test ways to slow browning.
Wednesday — Explore Physics: Do Apples Float?
Make predictions and investigate whether apples sink or float.
Thursday — Try Chemistry: Erupting Apple Volcano
Observe an acid-base reaction.
Friday — Explore Life Science: Apple Life Cycle
Learn how an apple grows from seed to fruit.
🔎 Math extension: Collect results from your apple observations or taste test and graph them with the Apple Graphing Activity.
💡 This gives kids a mix of observation, chemistry, physics, and life science without needing a complicated unit.
