Recommended Grade Level:
Kindergarten – 5th Grade
Core Life Science Concepts Covered:
- Animal adaptations and seasonal behavior
- Seed dispersal and plant changes
- Decomposition and nutrient cycles
- Living vs. nonliving classification
- Environmental observation and weather patterns
NGSS Guiding Questions
- What is the phenomenon?
Plants and animals change and respond to the fall season. - What evidence do I observe?
I see leaves changing color, seeds falling, animals migrating, and the weather becoming colder. - What can I conclude or explain?
Living things adapt to seasonal changes to survive and complete their life cycles.
Animal Life Science for Fall
Observe how animals prepare for colder weather and shorter days.
- Hibernation Activities: Learn which animals go into deep sleep and how they survive without food.
- Migration Activities: Discover why birds, butterflies, and other animals travel long distances in the fall.
- Diurnal and Nocturnal Animals: Identify which animals are active during the day or night and how their behavior shifts in autumn.
- Winter Animal Adaptations: Explore camouflage, fur changes, and food storage with fun activities and observations.
- Winter Food Chains: Create a seasonal food chain model that illustrates how energy flows through a fall or winter ecosystem.
- Spider Life Cycle Lapbook: Learn about the spider life cycle and anatomy of a spider as you assemble this information-packed lapbook (free printable)
Plant Life Science for Fall
Plants also change in the fall—from dispersing seeds to going dormant.
- Seed Dispersal Experiment: Test how seeds travel by wind, water, animals, and more. Fall is the perfect time to find real seed pods.
- Seed Counting with Fruits: Slice open apples, pumpkins, or peppers to explore how many seeds each produces.
- Leaf Color Change Science: Investigate why leaves turn red, yellow, or orange in the fall.
- How Leaves Breathe: Use fall leaves to observe tiny leaf pores and gas exchange.
- Decomposing Pumpkin Experiment: Watch what happens as a pumpkin breaks down and returns to the earth.
Ecosystems and Environmental Science
Use fall as a lens to study changing habitats, seasonal cycles, and weather patterns.
- Build a Habitat STEM Challenge: Design and create animal shelters using natural or recycled materials.
- Composting and Decomposition: Start a mini compost pile with fallen leaves and scraps.
- Nature Walk Observation Activity: Collect signs of fall—leaves, seeds, animal tracks—and sort them into living and nonliving.
- Living vs. Nonliving Fall Sort: Use real fall objects to discuss what makes something alive.
- Fall Temperature Tracker: Record daily temperatures throughout the season. Use your data to discuss how colder weather impacts plants and animals preparing for winter.
