Observing Phenomena Discuss: Have you ever seen a wilted plant? What do you think causes this?

Observe this phenomenon: This plant’s wilted leaves lifted.

See It!

Look at a plant. What do its leaves look like? Are they droopy or lifted? What do other parts of the plant look like?

Think of what you already know about wilted plants. Write questions you have.

INVESTIGATION

Animals need air, water, and food to survive. Plants use air, water, and sunlight to make food. Without water and sunlight, plants will die.

Marigold Experiments Look at these two plants. Talk with your class: • Which plant is healthy? How do you know?

• How do you know when a plant is not growing or is not healthy? What will it look like?

What do plants need to survive? Let’s investigate!

Planning Your Investigation You will investigate what plants need to survive. In your group, choose one plant need, either water or sunlight.

• I f you are investigating sunlight, you will give one of your plants light. Your other plant will not get any light.

• If you are investigating water, you will give one of your plants water. The other plant will not get any water.

Then, complete the chart on the next page according to your investigation question.

Carrying Out Your Investigation Follow the plan on your planning sheet. Use crayons or markers to label your plants.

Sunlight Investigators: • Cover one plant with a paper bag.

• Use the spray bottle to water your plants each day. Be sure to put the paper bag cover back on the correct plant after you water it.

Water Investigators: • Use the spray bottle to water one plant. Make sure you water the same plant each day.

• Do not water the other plant.

1. Animal Needs Have you ever tried to hold your breath? You cannot hold it for very long because you need air.

Animals need air to survive. To survive means to stay alive. If animals do not get air, they die. Many animals breathe air into their lungs. Fish take in air through their gills.

Animals need water, too. Many animals get water by drinking it. The water may be in a stream or a pond.

It might be drops of water on a leaf.

Some animals get water from plants they eat. Some animals need a lot of water. Other animals do not need as much water.

Animals need food to survive.

This mountain goat gets food by eating grass plants.

Animals get their food by eating plants or other animals.

Mountain goats eat grass. Killer whales hunt other animals.

Foxes eat berries and crickets.

Some animals need a lot of food. Others do not need as much food.

2. Plant Needs Animals need air, water, and food to survive. Do plants need the same things to survive?

Observe this phenomenon: A beetle comes to a flower to eat nectar. Then, it leaves with something stuck to its body.

Animals need plants for shelter and food. Plants need animals to spread their seeds around and carry pollen. Nature can give engineers ideas for ways to design new products and share ideas.

Introducing Pollinators In this investigation, you will learn more about how bees pollinate flowers. You will use what you learn to design a hand pollinator. This is the problem your engineering team has been asked to solve.

Designing a Solution You and your team will design a tool that people can use to move pollen from one flower to another.

Get a bin of materials for your team.

Look at all the different materials your team can use to design your hand pollinator.

Your “hand pollinator” needs to do the job of bees in a garden.

Talk with your team: • What materials would be best to use to pick up pollen?

• What materials would be best to carry the pollen from one flower to another flower?

• Will you need a handle for your pollinator? What materials could you use for a handle?

1. Animal Survival You know that animals need food to survive. Squirrels eat nuts. Hawks eat mice. Bears eat fish and berries.

Food is one way that animals depend on the plants and other animals that live nearby.

Why are the crows on the deer? They are eating ticks. Tick bites can make deer and other animals sick. The crow depends on ticks for food. The deer depends on the crow to eat the ticks.

Some plants have seeds with hooks that stick to an animal’s fur. The animal carries the seed to new places.

Other plants have seeds inside fruits that animals eat. The seeds pass out of

The engineer decided to design a new kind of fastener. Engineers make drawings to share ideas. One piece would have hooks on it like the burr seeds. The other piece would have loops on it like the fur on his dog. The hooks need to hold on tight to the loops. It took many years to find the right materials.
