Hi Jessica here my class and other class we have
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.
Task 1; Read the question carefully and write the answer to these questions.
- What do we need to find out? what will happen to salt and water when there freeze.
- How will we find it out? do it home do at a friend do it where your staying at
- How will we record what we find? do it on your blog or on paper
- What equipment do we need for the experiment? a cup, a measuring cup, salt, water and a freezer
- How long will it take? 1 to 2 night
Task 2: What are the steps that you will take to make the experiment?
List them in 6 steps.
Step 1; get a cup
Step 2: get a measuring cup
Step 3: measure the salt
Step 4: measure the water
Step 5: then put it in the fezzer
Step 6: wait 1 or 2 night
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:
- Beakers
- Water
- Measuring spoons or cups
- Salt
The Plan.

The Process
my mum said it wont freeze but it did and i was surprise it did freeze.
