My First Garden Plan
Design a tiny garden! Choose 3 different seeds and DRAW where each one will go in a planter box or garden patch. This is about planning a garden, not just one seed.
Materials and setup
- seeds
- cups
- soil
- water
- magnifying glass
- flowers for dissection
- plastic bag
How this changes by age
Pre-K (ages 3–4)
Design a tiny garden! Choose 3 different seeds and DRAW where each one will go in a planter box or garden patch. This is about planning a garden, not just one seed.
Steps
- Show the child seed packets for 3 different plants (e.g., carrots, lettuce, sunflowers).
- Talk about each plant: how tall it grows, how much room it needs, sun or shade.
- On a big piece of paper, draw a rectangle for the planter box or garden patch.
- Help the child draw and color where each seed will go: tall plants in the back, short ones in the front.
- Optional: actually plant the seeds in the planned spots in a window box or patch.
- Tell a grown-up one thing that surprised you.
- Draw your plant at day 1 and day 7 side by side.
Learning objectives
- Plan a small garden with multiple different plants
- Match plants to spots based on size and sunlight needs
- Make a simple layout drawing for a real-world plan
Kindergarten (ages 5–6)
Study plant parts and their jobs. Dissect a flower, examine roots, and learn how plants make their own food through sunlight.
Steps
- Learn 5 plant parts: roots (drink water), stem (transport), leaves (make food), flower (make seeds), seeds (grow new plants).
- Carefully pull a weed and examine the roots. Wash them and look closely.
- Dissect a real flower: gently pull apart petals, stamen, and pistil. Draw and label each part.
- Experiment: put a white flower in colored water. Watch the stem carry color to the petals over 24 hours.
- Draw a complete plant with all 5 parts labeled and their jobs described.
- Tell a grown-up one thing that surprised you.
Learning objectives
- Identify and name the main parts of a plant
- Describe the function of roots, stems, leaves, and flowers
- Observe how stems transport water through the plant
Early elementary (ages 6–8)
Investigate photosynthesis, plant adaptations, and life cycles. Design controlled experiments to test what plants need to thrive.
Steps
- Learn about photosynthesis: plants use sunlight, water, and CO2 to make sugar (food) and release oxygen.
- Design an experiment: plant 4 identical seeds. Give each different conditions (light vs. dark, water vs. dry). Predict outcomes.
- Observe and record growth data for 2 weeks. Which conditions produced the best growth?
- Study plant adaptations: cactus spines, deep roots in deserts, broad leaves in rainforests. Why did each adapt?
- Diagram the life cycle of a flowering plant: seed, germination, growth, flowering, pollination, seed production.
- Create a field guide page for 3 plants in your yard, including drawings, measurements, and habitat notes.
- In one sentence, tell a parent or sibling what surprised you today.
Learning objectives
- Explain the basic process of photosynthesis
- Design and conduct controlled plant experiments
- Identify plant adaptations for different environments
Upper elementary (ages 8–10)
Study advanced plant biology: cell structure, transpiration, plant responses to stimuli, genetic variation, and the role of plants in ecosystems.
Steps
- Examine a plant cell under a magnifying glass (thin onion skin). Compare to animal cells. Draw and label: cell wall, chloroplast, vacuole.
- Investigate transpiration: cover a leafy branch with a plastic bag. Observe water droplets forming inside over several hours.
- Test phototropism: place a plant in a box with one hole for light. Document how the plant grows toward light over 1 week.
- Research genetic variation: why are there so many varieties of apples, tomatoes, or roses? How do farmers use selective breeding?
- Analyze the role of plants in an ecosystem: producers, oxygen creators, habitat providers, soil anchors. Create a food web diagram.
- Write a scientific research paper on a plant topic of choice, including hypothesis, methods, data, and conclusions.
- In one sentence, tell a parent or sibling what surprised you today.
Learning objectives
- Compare plant and animal cell structures
- Investigate transpiration and phototropism through experiments
- Analyze the ecological importance of plants in food webs
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.
