Aim: To learn the names of 10 household chemicals and identify if they are a solid, liquid or a gas.

Definitions:

1. Element; A single form of a chemical
2. Compound: A mixture made up of 2 or more elements
3. Reaction: A process in which chemicals mix together to form a new substance.
4. Mixture: When two or more elements are mixed together.

Equipment:

1. lemon juice   
2.  salt
3.  sugar
4.  vinegar
5.  Lemonade bubble
6.  onion gas
7.  baking soda
8. milk
9. cornflour
10. Bana

Steps:

1.search the name up

2.then put the image on the table

3.then find the name of each one acids name

4.then writ the name of each things acids on the table

Repeat the steps for all the chemicals.

Task 1: Put the 10 chemicals in a chart with the titles - Name, Chemical ingredient(s), Image, Solid/Liquid/Gas.

Name	Chemical	Image	Solid/Liquid/Gas
Lemon juice	citric acid		Liquid
Salt	Sodium chloride		solid
Sugar	Sucrose		solid
Vinegar	Acetic acid		Liquid
Lemonade bubbles	Carbon dioxide		Liquid
Onion gas	sulfenic acid		gas
Baking soda	Sodium hydrogen carbonate		solid
Milk	Lactose		Liquid
Cornflour	Cornstarch		solid
Banana	Appearance		solid

CONCLUSION: ( WHAT DID YOU LEARN OR SEE)

Aim: To see what happens when baking soda and vinegar are combined.

fAIM: 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?
2. How will we find it out?
3. How will we record what we find?
4. What equipment do we need for the experiment?
5. How long will it take?

The Procedure

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

List them in 6 steps.

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
