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? We need to find out it how many salt we need to put in the cup.
- How will we find it out? Leaving a camera or go-pro inside the refrigerator.
- How will we record what we find? Using camera overnight.
- What equipment do we need for the experiment? Water, salt, and
- How long will it take?24 Hours.
The Procedure
Task 2: What are the steps that you will take to make the experiment?
List them in 6 steps.
Step 1;Grab cup.
Step 2:Pour water inside.
Step 3:Grab some salt.
Step 4:Put the salt in the cup with the water.
Step 5:Leave it inside the freezer overnight.
Step 6: Then look what happens.
Step 2:Pour water inside.
Step 3:Grab some salt.
Step 4:Put the salt in the cup with the water.
Step 5:Leave it inside the freezer overnight.
Step 6: Then look what happens.
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:
- Beakers
- Water
- Measuring spoons or cups
- Salt
Hello Jullien!
ReplyDeleteWell done on your science experiment write up! I can give you 1/2 points for the work you have shared with us. You have a clear plan and procedure but you have not included your sketch for part 3.
In order to earn your other point, please update this post and leave me a comment back so I can check your work. I am looking forward to seeing your completed drawing.
