Science activity
Seed Scavenger Hunt
Find seeds hiding in nature! Look for acorns, pinecones, dandelion puffs, and seeds inside fruits.
Materials and setup
- bags for collecting
- magnifying glass
- notebook
- pencil
- camera or phone
- cups and soil for planting
Parent note
CRITICAL SAFETY: never let a child eat any wild berry, seed, or nut. Many common landscape plants (yew, holly, pokeweed, privet, nightshade, castor bean, laburnum) have berries or seeds that are toxic or deadly. Rule: LOOK, don't taste. For the 'seeds inside fruit' step, use store-bought produce only. Wash hands thoroughly after the hunt. For the dandelion seed-blowing step, some children have allergies — watch for sneezing/wheezing. Apply sunscreen, bring water. Stay with your child in public parks. Reduced-mobility adaptation: all seed collection can be brought to a seated child by the parent. The helicopter-drop experiment (maple spinners) can be tested from a balcony or the top of a staircase, with the seated child observing from a safe vantage. Germination cups on a windowsill, paper helicopter construction, weighing, and measuring are all desk-based.
How this changes by age
Pre-K (ages 3–4)
Find seeds hiding in nature! Look for acorns, pinecones, dandelion puffs, and seeds inside fruits.
Steps
Learning objectives
- Recognize that seeds come in many shapes and sizes
- Understand that seeds are found in fruits, cones, and flowers
- Begin to understand seed dispersal through observation
Kindergarten (ages 5–6)
Find 6+ different types of seeds. Sort them by how they travel: wind, water, animals, or gravity. Plant one to watch it grow!
Steps
Learning objectives
- Classify seeds by their dispersal mechanism
- Observe aerodynamic properties of wind-dispersed seeds
- Begin a germination experiment through planting
Early elementary (ages 6–8)
Study seed dispersal mechanisms. Collect 8+ seed types, classify by dispersal strategy, design seed dispersal experiments, and track germination.
Steps
Learning objectives
- Classify seeds by dispersal strategy using structural evidence
- Design and conduct comparative experiments on seed dispersal
- Track germination as a longitudinal observation experiment
Upper elementary (ages 8–10)
Investigate seed ecology: dispersal biomechanics, germination requirements, seed bank concepts, and plant reproduction strategies.
Steps
Learning objectives
- Analyze seed dispersal through biomechanical experimentation
- Design controlled germination experiments with proper variables
- Evaluate reproductive trade-offs in plant biology
Safety and evidence note
Read the full activity before beginning. An adult should supervise tools, heat, food, outdoor work, movement, and experiments as appropriate. Completion records that the activity was done; the child’s explanation, work sample, photo, or demonstration is stronger evidence of learning than a completion check alone.

Animal Body Language & Behavior
Animals talk all the time — they just don't use words. A dog wags its tail high and loose when it is happy, but tucks its tail between its legs when it is scared. A cat holds its tail straight up like a pole to say hello, but puffs it up like a bottle brush when it is startled. A bird sings soft songs on a calm morning, but makes a sharp 'chip-chip-chip' alarm call when something dangerous is near. If you watch closely, you can understand exactly what they are feeling.

Animal Habitats & Needs
Here is an animal that will surprise you: the mantis shrimp can punch with the force of a bullet. It sees 16 types of color — humans only see 3. And it lives in a burrow it digs itself at the bottom of the ocean. When scientists first discovered how powerful the mantis shrimp's punch was, it shattered the equipment they were using to measure it. Every animal's body is perfectly matched to the place it lives. Today you'll discover how that matching works.
Animal Tracks & Signs
Look for clues that animals have been nearby! Find footprints, nests, holes, or chewed leaves.
