## What Do Plants Need To Grow?

I am learning to understand the different things that plants need to be able to grow and live.

I know I can do it when I know that plants need sunlight, soil/nutrients, water, air/oxygen and space to be able to grow.

Last week we looked at the different parts of a plant. This week, we are going to learn about the different things that most plants need to be able to grow and survive.

Most plants need 5 things to be able to grow. These 5 things are:

Water – Like humans, plants need water to be able to survive.

Air – Plants also need air to be able to breathe and survive.

Soil – Plants collect nutrients from the soil through their roots. This is like their food.

Sunlight – Most plants need sunlight to be able to develop and grow.

Space – Plants need room around them so that they can spread their branches and roots.

Now that you know what plants need to survive, your task this week is to search for some healthy and unhealthy plants in a park, your backyard, or your neighbourhood.

You will need to try to identify why those plants are healthy or unhealthy.

If the plant is unhealthy, what is it missing? Does it have enough sunlight? Is it living in healthy soil? Is it being watered often? Is there enough space for it to grow? Is it getting enough air?

## Measuring Capacity

I am learning to test my capacity order from yesterday with water.

I know I can do it when I can measure objects correctly using water.

Using the objects from yesterday, you will now test if your prediction is correct.

Today you are going to test if your prediction from yesterday was correct.

Head outside or use the kitchen sink to test with water, the order you lined up yesterday.

Be sure to use the same cup for each object to keep your results consistent.

Once you discover how many cups of water the object can hold, write the result beside your guess from yesterday.

Were you correct? Were two very close in capacity?

### Challenge

Find another object that would hold the exact same amount of water as 1 of the items you have chosen.

## Predicting capacity

I am learning to predict and order objects to measure capacity.

I know I can do it when I can predict and order objects to measure capacity.

To understand capacity, we need to first understand that capacity means how much something can hold. If we measure the capacity of an object using water, we are seeing how much water it can hold.

Watch the following video to learn a bit more about capacity and why we need to know what it means:
