BIG picture

• What skills will you be developing this lesson?

• HSW- by planning and carrying out an investigation/ Interpreting data/ evaluating an experiment

• Literacy- by writing explanations using correctly spelt keywords and good grammar.

• Team work- during a practical investigation

• Participation- during a practical activity

• Reflection- through self and peer assessment of each outcome

Key Question: What is the difference between an element and a compound?

•Quick Discussion:•What do you already know?

Where does this lesson fit in to the rest of the topic? Lesson 2

Keywords:Create sentences using the keywords to show that you know what they mean.

Put your hand up if there is any key word from the list that you don’t understand.

• Carbonates

• Metal

• Carbon Dioxide

• Salt

• Calcium carbonate

• Sodium carbonate

• Copper carbonate

New Information for Learning Outcome 1

• Visual: Demonstration• Audio: Demonstration• Kinaesthetic: Class experiment

• When a metal carbonate reacts with an acid, the products are a salt, carbon dioxide and water:

metal carbonate

carbon dioxide wateracid salt

New Information for Task 1

• Your task is going to be to carry out the reaction between acid and metal carbonate.

• You will also carry out a test for the reaction to show that it has taken place.

Learning Activities for Outcome 1

What do you need to do to be safe when conducting this experiment?

Learning Activities for Outcome 1

• What equipment will you need?

• 3 test tubes• Test tube rack• Copper carbonate,• Calcium carbonate, • Sodium carbonate• Spatula• Pipette• Hydrochloric acid• One boiling tube with bung and delivery tube• One test tube of limewater

Learning Activities for Outcome 1

Learning Activities for Outcome 1

New Information for Task 1b

• Test for carbon dioxide?

When carbon dioxide gas is bubbled through limewater, it turns the limewater cloudycloudy or milky whitemilky white.

Gas

Limewater turns milky/cloudy

New Information for Task 1b

• When an acid is added to a carbonate what happens to the carbonate?

• What gas is produced?

• What happens to buildings which are made of carbonates?

New Information for Learning Outcome 2

When you add a bath bomb to your bath it fizzes and releases lots of bubbles.

New Information for Learning Outcome 2

The main ingredients in a bath bomb are citric acid and bicarbonate of soda.

When these are added together in the presence of water, a chemical reaction takes place and a gas is made (that’s where the fizzing comes from)

Colouring, fragrance and oil is also added.

THINK!What gas do you think is made?

New Information for Learning Outcome 2

Bicarbonate of soda’s other name is sodium bicarbonate. When acid is added to a carbonate this chemical reaction happens:

Acid + Metal carbonate Metal salt + Water + Carbon dioxide

New Information for Learning Outcome 2

1. Weigh out 15g of each of these : Citric acid, bicarbonate of soda and corn flour.

2. Mix these dry ingredients well. Get out any lumps. Put the mixture into a plastic beaker.

3. Measure out 9ml of sunflower oil in a measuring cylinder using a funnel to avoid spillage.

4. To the oil add 5 small drops of food colouring and enough fragranced oil to bring the total volume up to 10ml.

5. Mix the wet ingredients well to disperse the food colouring.

6. Add the wet to the dry ingredients a bit at a time, stirring well all the time.

7. When it has all been incorporated mould the mixture with your hands into a ball. You will have to squeeze pretty hard and it will make a mess! Do it over newspaper please. If the mixture does not hold together then return to the plastic beaker and stir in a little more sunflower oil and try again.

To present your bath bomb wrap it in tissue paper and tie with ribbon. Add a tag on which you can write a message or instructions on how to use it.

Happy Fizzing!
