Science activity
Insect Investigation
Go on a bug hunt! Look under rocks, near plants, and in the grass for insects. Count their legs, look at their colors, and draw what you find.
Materials and setup
- magnifying glass
- notebook or journal
- pencil
- crayons
How this changes by age
Pre-K (ages 3–4)
Go on a bug hunt! Look under rocks, near plants, and in the grass for insects. Count their legs, look at their colors, and draw what you find.
Steps
- Grab a magnifying glass and a notebook, then head outside. SAFETY: a magnifying glass can focus sunlight into a hot point that can burn skin or start a fire — hold it close to the bug, not angled at the sun, and never leave it sitting in the grass.
- Look carefully in the grass, under rocks (put them back!), near flowers, and on tree bark.
- When you find a bug, observe it together: 'How many legs? What color? Is it moving fast or slow?'
- Draw 2-3 bugs you found in your notebook.
- Talk about being gentle: we look but don't squish! Put rocks back where you found them. Wash hands after touching soil or bugs, and avoid fuzzy caterpillars, wasps, bees, ants, and spiders (some sting or bite).
- Tell a grown-up one thing that surprised you.
- Draw the animal and sticker-tag one body part you noticed.
Learning objectives
- Observe insects using basic scientific tools (magnifying glass)
- Identify simple characteristics of insects: legs, color, size
- Practice respectful observation of living things in nature
Kindergarten (ages 5–6)
Conduct an insect survey! Search different habitats (grass, soil, bark, flowers), count and identify insects, and record findings in a field journal.
Steps
- Bring a magnifying glass, journal, and pencil outside.
- Search 3 different micro-habitats: under a rock, in grass, near flowers.
- For each insect found, draw it and record: number of legs, color, size, where found.
- Count total insects found in each habitat. Which had the most?
- Research one insect you found: what does it eat? Is it helpful to the garden?
- Tell a grown-up one thing that surprised you.
Learning objectives
- Conduct a systematic survey across different micro-habitats
- Classify insects based on observable characteristics
- Compare insect populations across different environments
Early elementary (ages 6–8)
Conduct a biodiversity survey: identify insect species, classify them by order (beetles, butterflies, ants, etc.), create detailed scientific drawings, and analyze habitat preferences.
Steps
- Learn the characteristics that define an insect: 3 body parts (head, thorax, abdomen), 6 legs, exoskeleton, usually wings.
- Survey 4 different micro-habitats for 10 minutes each. Use a field guide or identification chart to identify insects to the family level if possible.
- Create detailed scientific drawings of 5 insects. Label body parts: head, thorax, abdomen, antennae, legs, wings.
- Organize your data in a table: insect name, habitat found, estimated size, behavior observed.
- Create a bar graph showing number of insects found in each habitat. Which habitat had the most biodiversity?
- Write a biodiversity report: describe your methods, present your data, and explain why certain habitats support more insect life than others.
- In one sentence, tell a parent or sibling what surprised you today.
Learning objectives
- Identify and classify insects by body structure and order
- Create detailed scientific drawings with labeled anatomy
- Analyze biodiversity data across habitats and draw evidence-based conclusions
Upper elementary (ages 8–10)
Design and conduct an entomological research project: study insect behavior, set up observation experiments, research insect ecology, and write a scientific research paper.
Steps
- Choose a research question about insect behavior: 'Do ants prefer sweet or salty food?' 'What time of day are pollinators most active?' 'Do insects prefer certain flower colors?'
- Design an experiment to answer your question. Define your hypothesis, independent variable, dependent variable, and controls.
- Conduct your experiment over 3-5 days with repeated observations. Record detailed quantitative data.
- Research your insect's role in the ecosystem: pollination, decomposition, food chain position, impact on agriculture.
- Analyze your data: create appropriate graphs, calculate averages, and determine whether your results support your hypothesis.
- Write a full research paper: Title, Abstract (100 words), Introduction (background and hypothesis), Methods, Results (with data tables and graphs), Discussion (what do results mean? sources of error?), Conclusion, and References.
- In one sentence, tell a parent or sibling what surprised you today.
Learning objectives
- Formulate testable hypotheses about insect behavior and design controlled experiments
- Conduct multi-day field research with repeated observations and quantitative data collection
- Write a complete scientific research paper with all standard sections
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 Habitat Diorama
Choose a favorite animal and build its home in a shoebox! Use natural materials, paper, and toy animals to create a habitat scene.
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.
