Making Sherbet

We need to write down our equipment and the steps we will go through to make our sherbet.

Once we have completed the materials and steps we can make sherbet.

While you are eating your sherbet you can answer the 5 questions at the end.

Equipment:

1. Sugar

2. Baking Soda

3. Raro Crystals

4. Cirtic Acid

5. Tartaric Acid

Steps

1. Add the baking soda sugar and citric acid together in a bowl.

2. Add the Raro crystals and tartaric acid together.

3. Add all ingredents together and place in a plastic bag.

4. Mix it well together and eat it. Yuck

Recipe:

1 teaspoon of powdered drink crystals (eg Raro)

1/4 teaspoon of citric acid

1 teaspoon of Icing Sugar

1/4 teaspoon Baking Soda.

Findings:

1. Which two ingredients in the sherbet are involved in the chemical reaction?

2. Which ingredients are not involved?

3. Can you think of any other chemical reactions that might happen in the kitchen?

4. Which ingredient is an acid?

5. Which ingredient is a base?

Acids and bases

Aim: To make red cabbage pH indicator for use on different household chemicals.

Red Cabbage Indicator experiment

Materials

1. Red Cabbage

2. Beaker

3. Bunsen Burner

4. Pipette

5. Sodium Hydroxide

6. Hydrochloric acid

7. Test tubes x5

8.  paper towels 
   

9. Test tube rack 

10. Water Steps

    1. Chop up the red cabbage into small pieces. Place in a beaker and cover with a small amount of water.

    2. Bring the solution to the boil using a bunsen burner and then turn off the heat. Let it sit to cool down.

    3. Pour the cabbage water through a paper towel into a beaker. The dark purple liquid in the jar is the pH indicator liquid.

    4. Suck up the indicator into a pipette.

    5. In a test tube, use the cabbage indicator and the pH chart below to test the acidity of the the hydrochloric acid and ammonium hydroxide.Findings.

       What is the pH of liquids.

       1. Sodium Hydroxide

       2. Hydrochloric acid

Science

 Bacteria 

Aim: To learn about bacteria and how they grow 

Equipment:

1. Agar dish

2. Cotton bud swab 

3. vivid pen 

Method: 

1 Collect the bacteria on cotton bud swab from taps, computer, keyboards or desk 

2. Divide the agar in half by drawing a line open the lid. 

3.wipe the swab onto the agar soloution.

4. Put the petri dish into the incubator for 1 week to allow the backteria to grow. 

5. Draw and label a bacteria 

6. Draw and label a scientific diagram of the experiment.
