Home Chemistry - Design an experiment Task 1 - 3

Home Chemistry - Design an experiment (Task 1 - 3) 

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. 


What do we need to find out?

My Answer: We need the ingredients and the ingredients are an amount of Salt, Water, a glass cup/beaker and a freezer.


2. How will we find out?
My Answer: We will find it out by mixing the Salt and the water in a glass cup and left it in the freezer overnight.

3. How will we record what we find?
My Answer: We can record it by taking a picture of it and post it in your blog.

4. What equipment do we need for the experiment?
My Answer: Salt and Water.

5. How long will it take?
My Answer: Overnight 


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 good amount of salt
Step 2: Get a good size cup/beaker
Step 3: Fill the cup with a good amount of water
Step 4: Mix the salt with the water in the cup/beaker
Step 5: Leave them overnight in a freezer
Step 6: Record what happened.


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

My answer:
