For educators and administrators, this is a chance to move beyond the textbook and inspire a love for scientific inquiry that is both tangible and memorable. This season offers a perfect blend of wonder and data, allowing us to connect foundational scientific principles to the world right outside our classroom window.

Fun Fall Science Experiments for All Ages

The Science of Autumn Leaves

The most iconic symbol of fall is the changing leaf, a phenomenon that offers a compelling lesson in biology and chemistry. While many of us learned that leaves change color because the tree “sucks out” the green, the true story is far more complex and fascinating. The green color in leaves comes from chlorophyll, the pigment responsible for photosynthesis.

As days shorten and temperatures drop, trees stop producing chlorophyll. This allows other pigments, which have been present all along, to finally shine through. These include the yellow and orange carotenoids and the brilliant red and purple anthocyanins that give certain trees their spectacular crimson hues. For a deeper dive into the science, explore this detailed explanation from the U.S. Forest Service on why leaves change color.

Experiment: Leaf Chromatography

This simple, yet powerful, experiment allows students to physically separate the pigments hidden within a green leaf, making the invisible visible. It’s a perfect activity to demonstrate that autumn’s colors are not new creations but are revealed as chlorophyll fades.

Materials:

• Freshly picked green leaves
• Rubbing alcohol (isopropyl alcohol)
• A glass jar or beaker
• Strips of coffee filter paper or chromatography paper
• A pencil

Procedure:

1. Tear the leaves into small pieces and place them in the jar.
2. Add just enough rubbing alcohol to cover the leaf pieces.
3. Use the back of a spoon to gently mash the leaves, releasing the pigments into the alcohol.
4. Hang a strip of coffee filter paper with a pencil so that the bottom of the paper just touches the surface of the alcohol.
5. Let the jar sit undisturbed for several hours. As the alcohol is absorbed and moves up the paper, it will carry the different pigments with it, separating them into distinct colored bands.

Apple Investigations and the Power of Oxidation

The classic apple a day can be a great entry point into the world of chemistry. When an apple is sliced open, its flesh turns brown due to a chemical reaction called oxidation. An enzyme in the apple reacts with oxygen in the air, creating a brown pigment.

This is the same process that causes rust to form on metal. This simple observation can be transformed into a rigorous scientific investigation by introducing a control group and variables. For more information on this food science principle, read this explanation of enzymatic browning from Oregon State University.

Experiment: Preventing Apple Browning

This activity challenges students to develop and test hypotheses about what substances can prevent or slow down the oxidation process.

Materials:

• Sliced apples (from the same apple for consistency)
• Small bowls or cups
• Various substances to test, such as lemon juice, salt water, vinegar, milk, or soda
• A control cup with just a plain apple slice

Procedure:

1. Label each cup with the name of the substance to be tested, plus one for the “control” group.
2. Place a slice of apple in each cup.
3. Coat each apple slice with its assigned substance, ensuring the control slice remains untouched.
4. Leave the apple slices out for several hours, observing and documenting the changes.
5. Students can rank the substances from most to least effective in preventing browning, providing a data-driven conclusion.

The Physics of Pumpkins

Fall is synonymous with pumpkins, and these versatile gourds can be used for far more than just carving. Their unique physical properties and hollow interior make them a fantastic subject for exploring concepts like density, displacement, and volume.

Experiment: The Great Pumpkin Float

This experiment is a fun way to demonstrate the concept of buoyancy and density. It challenges the intuitive belief that a large, heavy object like a pumpkin can’t float. You can learn more about how objects float or sink from this buoyancy lesson plan provided by National Museum of the USAF.

Materials:

• A pumpkin
• A large bucket, tub, or kiddie pool filled with water
• Various small objects to place inside the pumpkin (e.g., small rocks, coins, marbles)
• A scale

Procedure:

1. Ask students to predict whether the pumpkin will sink or float. Most will guess it will sink.
2. Gently place the pumpkin in the water. It will float! Explain that although it is heavy, the pumpkin’s internal cavity is filled with air, making its overall density less than that of the water.
3. Now, challenge students to make the pumpkin sink. They can add small, dense objects to the inside. They will observe that the pumpkin’s density increases with each item added, until it finally sinks. This introduces the concept of how a hollow object can be made to sink or float depending on its overall density.

Engineering a DIY Weather Station

Fall weather is famously unpredictable, making it a perfect subject for a hands-on STEM project. Instead of just talking about wind and rain, why not have students build their own tools to measure these phenomena? This project incorporates principles of physics and engineering design, fostering a deeper understanding of meteorological concepts.

Project: Build an Anemometer

An anemometer is a device used for measuring wind speed. Building one from simple materials helps students understand how wind applies force and how that force can be measured. For more resources on weather instruments, check out this page from the National Oceanic and Atmospheric Administration (NOAA).

Materials:

• Four small paper cups
• One slightly larger cup for the base
• Two straws
• A pencil with an eraser
• A pushpin
• Stapler

Procedure:

1. Staple one straw to the side of the larger base cup.
2. Push the pencil eraser through the center of the base cup, making sure it is upright and sturdy.
3. Make a small hole in the center of the two straws. Thread one straw through the other to form a cross.
4. Attach the four small cups to the ends of the cross, making sure they all face the same direction (e.g., all cup openings facing counterclockwise).
5. Place the cross on top of the pencil eraser and secure it with a pushpin, ensuring it can spin freely.
6. Take the anemometer outside on a windy day and watch it spin! Students can use a timer to count the number of rotations in a minute and compare their findings to a professional weather forecast.

Exploring the Biology of Seeds

Autumn is a season of harvest and dispersal. It’s a prime time to explore the incredible variety of seeds and the clever ways plants use to spread them. From the winged samaras of maple trees to the burrs that stick to clothing, each seed has a story to tell about adaptation and survival.

Experiment: Seed Dispersal Investigation

This simple, hands-on activity allows students to become botanists and observe the different strategies plants use to ensure the next generation. For a detailed guide on seed types and their dispersal methods, visit the Missouri Botanical Garden’s seed dispersal page.

Materials:

• A variety of fall seeds (e.g., acorns, pinecones, maple keys, burrs, sunflower seeds)
• A microscope or hand lens
• A tray or paper to sort seeds
• Field guides or online resources for identifying plants

Procedure:

1. Take a nature walk with students to collect as many different types of seeds as possible.
2. Back in the classroom, have students use a microscope or hand lens to examine the structure of each seed.
3. Ask them to sort the seeds into groups based on how they think they are dispersed. Categories could include:
   • Wind: Seeds with wings or tufts (maple keys, dandelion)
   • Water: Seeds that are buoyant (coconuts, some nuts)
   • Animals (external): Seeds with hooks or barbs (burrs)
   • Animals (internal): Seeds that are part of a fruit and are eaten
   • Self-propelled: Seeds that pop open (jewelweed)
4. Discuss how the shape and weight of each seed is an adaptation for its specific dispersal method. This activity reinforces key concepts in botany and ecology.
