If you are teaching elementary science, you’ll love this collection of leaf science experiments for elementary!
These fall science experiments cover everything from photosynthesis to a leaf’s life cycle and will show kids everything they need to know about fall leaves and the science behind them!

If you like these leaf science experiments, you’ll also like these pumpkin science experiments, creative STEM activities for kids, and our complete list of science experiments for kids.
NGSS Alignment

If you are following NGSS or some other state science standard, these are some of the catagories that these experiments align with:
- K.Interdependent Relationships in Ecosystems: Animals, Plants, and Their Environment
- 2.Earth’s Systems: Processes that Shape the Earth
- 3.Inheritance and Variation of Traits: Life Cycles and Traits
- 3.Weather and Climate
- 5.Matter and Energy in Organisms and Ecosystems
- 2.Structure and Properties of Matter

Leaf Science Experiments for the Classroom

While most of the experiments on this list were first done at home, they can be used in a classroom setting as well.
If you do any of these experiments in the classroom, you’ll want to have supplies for groups of 4-5 students at a time.
Here are some of our favorite science kits!

How to Set Up a Leaf Science Experiment

Most of the experiments on this list take 2-3 sessions to complete.
Each kid needs some sort of science journal or worksheet to record their observations during the experiment.
Make sure you have all supplies for the experiments on hand and divide everything into groups before handing out to students.
If you’re doing the experiment at home, you can just set up everything ahead of time.
Go over science safety and the science behind the experiment before allowing kids to start. Once the lesson is completed, then you can hand out the supplies.
This will help eliminate waste, mess, and misuse of the equipment.
If you don’t want kids to use breakable materials, you can switch out most of the glass supplies for plastic equipment for these experiments as none of them have any material that has to be in a glass beaker.

And now, on to the leaf science experiments!
Brilliant Leaf Science Experiments for Elementary
These leaf science experiments will teach kids everything they need to know about leaves, why leaves change color, a leaf's life cycle, and more!
Chromatography is a really fascinating part of chemistry. CHromotography sheets are used to determine and prove what materials are in a substance based on how far that substance travels up the chromatography strip.
In this leaf chromatography experiment, kids can find out what colors are hiding inside of fall leaves, as the chromatography strips stratify the colors inside of each leaf.
The apple tree life cycle worksheet shows kids the process of leaf transformation and tree formation from seed to fruit. While this worksheet is aimed at younger elementary students, older kids can help use this worksheet to go deeper into photosynthesis and the life cycle of trees from a cellular level.
Trees make oxygen through leaves through the process of photosynthesis. While learning about photosynthesis and the cell structure of leaves, kids can do this simple experiment to determine how much oxygen trees are producing and if different leaf varieties create different levels of oxygen.
If someone were wanting to plant trees to create more oxygen in an area, what would the best variety be?
Crystals are fascinating for kids, and salt crystal leaves are simply a fun leaf-themed way to explore crystals during the fall.
Salt crystals will always form in a square shape due to their ionic bonds and molecular bonding patterns. Kids can use this experiment to explore a variety of crystal science and leaf science at the same time.
In this simple leaf science experiment, kids can explore how water gest to tree leaves from the roots. Colored water shows the path the water travels!
Learn about the types of leaf shapes and their scientific definitions. Both younger and older elementary students will learn a lot with this activity.
Using rubbing alcohol, kids can extract color from leaves and find out what chlorophyll is, and why it changes color during the seasons (and why sometimes it doesn't!)
Get an in-depth lesson plan on photosynthesis that you can use to go along with any of the other leaf science experiments in this list.
