Create a shadow clock by marking positions with chalk throughout the day, demonstrating Earth’s rotation and the sun’s apparent movement. Graph your measurements to visualize how shadow length changes, connecting this data to time-telling methods used before modern clocks. Repeat the experiment monthly to observe seasonal changes in shadow patterns and discuss Earth’s tilt and orbit around the sun.

Fall Science Challenges: Investigating Change and Decay

Fall transforms your backyard into a natural laboratory where decomposition and chemical changes happen right before your eyes. These challenges let you explore the science behind autumn’s dramatic transformations.

Leaf Color Chemistry Extraction Experiment

You’ll extract hidden pigments from colorful fall leaves using rubbing alcohol and coffee filters. Collect different colored leaves like red maples, yellow birches, and green oaks, then crush them in small jars with alcohol. Place coffee filter strips in each jar and watch as capillary action separates the pigments into distinct bands of color. This chromatography experiment reveals that leaves contain multiple pigments year-round, but chlorophyll masks them until it breaks down in fall.

Apple Oxidation Prevention Challenge

Test which household items best prevent apple browning by creating controlled experiments with lemon juice, salt water, honey, and plain water. Cut identical apple slices and dip each in a different solution, then observe browning rates over several hours. Record your findings in a data table comparing color changes and timing. You’ll discover how acids and antioxidants slow enzymatic browning while learning about chemical reactions in food preservation.

Seed Dispersal Method Investigation

Create a seed collection expedition to study how different plants spread their offspring through wind, water, animals, and explosive mechanisms. Gather maple helicopters, dandelion parachutes, burdock burrs, and touch-me-not pods to test their dispersal effectiveness. Build simple wind tunnels from cardboard tubes and fans to measure flight distances, or time how long seeds float in water containers. Document which designs work best for different environmental conditions.

Winter Science Challenges: Understanding Cold Weather Physics

Winter transforms your backyard into a natural physics laboratory where frigid temperatures create perfect conditions for exploring scientific principles. These cold-weather experiments help your family understand how temperature affects matter and energy.
