Aim: To learn about the makeup of different white powders.

There are  a number of different white powders in our everyday life. Some of these are harmful and others are not. Test the four white powders listed to see which one has been found at the airport.

Here are some examples of everyday kitchen white powders.

On the black cardboard using a microscope you need to record what you see. You will be given a small amount of 4 white powders on your cardboard. Look at them under your microscope and record what you see. 
Do not mix the powders or taste the powders.

Food chain:

Create your own food chain from the Kyle park wetlands below. Use the food chain above as an example.







Food  Webs:

Definition: A food web is similar to a food chain but larger. A food web uses arrows to show the energy relationships among organisms. Food webs show how plants and animals are connected in many ways.
