AIM: DESIGN AN EXPERIMENT THAT TESTS THE AMOUNT OF SALT THAT MUST BE IN WATER BEFORE IT WILL NOT FREEZE WHEN LEFT OVERNIGHT IN THE FREEZER.

When we design an experiment there are some important questions that we must answer first. This is part of the planning stage and will help to give us some ideas. 

Record these answers on your blog.

The Plan.

Task 1; Read the question carefully and write the answer to these questions. 

1. What do we need to find out how much slat it takes to make water not freeze
2. How will we find it out by doing the experiment at your house
3. How will we record what we find my put on you docs
4. What equipment do we need for the experiment salt a cup of water and a freezer
5. How long will it take overnight

The Procedure

Task 2: What are the steps that you will take to make the experiment? 

List them in 6 steps.

Step 1;you will need to get you ingredients
Step 2:get a cup of water
Step 3:get you slat 

Step 4:put the slat in the cup of water                   
Step 5:put it in the  freezer
Step 6:then take it out

The Process

Task 3: Draw on a piece of A4 paper the 6 steps that you will use to test the amount of salt in water before freezing. When we are making drawings in science  it needs to be labelled clearly, kept tidy and named. Once you have completed the drawing it must be photographed and uploaded to your blog.

In your drawing you will use:

1. Beakers
2. Water
3. Measuring spoons or cups
4. Salt
