Science Unit 2 Test: Plants, Animals & Habitats
Name Date
Part 1: Plant Structures & Needs
Jay set up four cups of bean seeds on wet paper towels. He checked them after two weeks. Use the table for questions 2 to 4.
| Cup | Water? | Light? | After two weeks |
|---|---|---|---|
| A | yes | yes | tall, green, 6 leaves |
| B | yes | no | tall, thin, pale yellow |
| C | no | yes | did not sprout |
| D | no | no | did not sprout |
- Which plant part carries water up to the leaves?rootsstemflowerseed
- Which cups did not sprout? What were they missing?
- Cup B sprouted in the dark, but it is pale. What does a plant need to grow green and strong?
- Jay wants to test only light. Which two cups should he compare?A and BA and CB and CC and D
Part 2: Animal Adaptations
Think about how body parts help animals get food.
| Tool beak | Seeds (rice) picked up in 30 seconds | Worms (spaghetti) picked up in 30 seconds |
|---|---|---|
| tweezers | 9 | 6 |
| spoon | 25 | 2 |
| clothespin | 7 | 8 |
- A bird has a short, thick, strong beak. Which food is it best for?hard seedsnectar deep in a flowertiny bugs under water
- Look at the table. Which tool picked up the most seeds? How many more seeds did it get than the tweezers?
- A woodpecker has a strong, pointed beak. How does it help the woodpecker get food?
- A frog has a long, sticky tongue. How does it help the frog?
Part 3: Habitats & Food Chains
Think about habitats and how plants and animals need each other.
- Which animal is best suited to live in a hot, dry desert?whalecamelbeavertrout
- A squirrel buries an acorn and forgets it. Later a little oak tree grows there. How did the squirrel help the oak tree?
- Draw a food chain for a squirrel. Start with the sun, then an oak tree, then the squirrel. Draw arrows.
- A garden has many flowers, but no bees or other pollinators visited this year. What will the flowers have trouble making?
Part 4: Investigation Design
Plan a test like a scientist.
- Pat wants to find out if a bean plant needs water to grow. Plan a test for Pat. Draw two cups. Then write: What is different: ____ What stays the same: ____ What I will look for: ____
