Hokey pokey

 Aim: To make hokey pokey using sugar, golden syrup and baking soda.

When the sugar and golden syrup combine with the baking soda it froths and makes carbon dioxide gas. That is why the hokey pokey has bubbles.

Materials:

1. 2 tablespoons Golden Syrup
2. 4 tablespoons sugar
3. 1 Heaped teaspoon of baking soda
4. Pot
5. Tablespoon and teaspoon
6. Bunsen burner
7. Grease proof paper

Method:

1. Put 4 tablespoons of sugar and 2 tablespoons of golden syrup in a saucepan and melt.
2. Bring to the boil and simmer gently for 5 minutes
3. Add baking soda and stir vigorously. 
4. Put the hokey pokey on a piece of grease prove paper to to cool.

The more the sugar syrup is cooked the browner it becomes. If it is left cooking for to long your hokey pokey becomes burnt. 

Explanation:

1.Why do we stir it ?

2.Explain why the hokey pokey rises and has bubbles?

3.What gas is made by the baking soda and sugar?

 Neutralization 

Acid + Alkaline (base) = water and salt

Aim: To look at the pH Scale and neutralise acid and alkaline substances using Univeral Indicator.

Neutralisation Experiment.

Equipment:

• Universal Indicator

• 1 M HCl ( Hydrochloric Acid)

• 1 M NaOH (Sodium Hydroxide)

• 4 Test tubes

• Test tube rack

• 2 plastic pipettes

Method:

1. Take a test tube rack with 1 boiling tube at each end of the rack and 4 test tubes.

2. Half Fill the boiling tube at one end with Sodium Hydroxide.

3. Half fill the boiling tube at the other end with Hydrochloric acid.

4. Fill each test tube with 5 drops of Universal indicator.

5. Using the pipettes you will add drops of the acid or alkaline to the test tubes to make colours. DO NOT MIX UP THE PIPETTES

Challenge:

To use the acids and alkalines to make the colours of the pH Scale.

Out of the 6 test tubes you should have the order of Red, Orange, Yellow, Green, Blue, Violet.

Once you have completed this you need to take a photo of your test tube rack and upload it onto your blog.

Activity:

Make your own copy of the pH scale. On the paper provided make 14 boxes and colour them the correct colours according to the pH scale. Use your test tubes as a guide.

One end is alkaline, one end is acid and Neutral is in the middle at pH7.

 

Folk Tale

This week for reading, I read a Folk tale called The Empty Pot.

A Folk Tale is a story that has been told for generations and has a moral or a lesson in it.

The Empty Pot is a folk tale about telling the truth.

The empty pot is about a young boy named Ping who entered a contest where you have to grow the best flower to become the Emperor of the country. But when Ping was trying to grow his flower, it wouldn't  grow so he tried everything he could. Then a year goes by and Ping was embarrassed because all the kids had nice good and cool one's. So then he just went and told the Emperor that his flower wouldn't grow but the Emperor already knew that the seeds wouldn't because he had cooked them before he gave them to the kids. But how did the other kids grow theirs? Well, they actually brought or used a different seed cause their one's wouldn't grow either. But Ping told the truth and he became the Emperor of China.
