Salt and water Experiment

Aim: DESIGN AN EXPERIMENT THAT TEST THE AMOUNT OF SALT THAT MUST BE PUT IN BEFORE FREEZING

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.

What do we need to find out?

The amount of salt that must be in water to see if it freezes or not once's you leave it in the freezer.

How will we find it out? We will find out by putting it in the freezer overnight and taking it out in the morning to see if it didn’t freeze.

How will we record what we find? We will record by a device that is waterproof and put it in a plastic bag and put in the freezer.

What equipment do we need for the experiment? When we go in the lab we will need safety glasses if doing an experiment and gloves.

How long will it take? It will take 8 hours until morning to see if it freezes or not.

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

List them in 6 steps.

Step 1; get a cup,beaker and measuring spoons/cups.

Step 2: add salt to your cup.

Step 3: get water and add it to a measuring cup.

Step 4: add both ingredients together mix them together.

Step 5: put in the freezer overnight Step 6:take it out of freezer in the morning and see if its freezes

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: pencil/pen, erasers

1. Beakers

2. water

3. Measuring spoons/cups

4. salt
