 Hay guys today i'm going to be telling you what I have learned. I have learned about the medals and the people that have won. 

Science

 YEAST

What Is Yeast? Yeast is fungy found in the air around us, its been around for a long long time/ years, There is yeast that is man made in a bottle, Over a thousand kinds of yeast, in bread there is co2 because the yeast eats the sugar and releases gas, 

What is Fermentation? the chemical breakdown of a substance by bacteria, yeasts, or other microorganisms, typically involving effervescence and the giving off of heat.

What effect does sugar have on yeast Too little sugar in dough can slow down yeast activity: Yeast is a lot like us – it loves to eat sugar. Yeast needs sugar to produce carbon dioxide – the leavening gas that causes the dough to rise. If there is not enough sugar available, the dough will rise slowly or not at all.

What are three foods that have yeast 

1. Ginger Beer 

2. Bread

3. Cake

 

Equipment: 

. Spoons

. Kettle 

. Bowl

. Beaker

. Cloth sieve 

. Funnel

. Plastic (pet) bottle and cap 

Materials:

. 50ml warm water.

. 1/2 tsp active dried yeast.

. 1/2 tsp sugar.

. 1/2 tsp ground ginger. 

Ginger Beer. ( For 1 Liter)

3/4 cup sugar 

1/2 tsp cream of tartar 

. 1L cold water 

. Juce of 1/2 lemon 

. 1 tsp ginger beer bug 

Method

1. Ina large bowl, put the sugar and cream of tartar, then add the warm water. 

2. Stir to dissolve the sugar before adding the cold water.

3. Add the ginger beer bug to the large bowl of cold water.

4. Stir well and then pour into your clean bottle. 

5. Lable your bottle with your group names. 

6. Place all the bottles in the class counter.

7. Store in a cool dark place for one week before drinking.

8. Make sure you open the bottle in the kitchen sink as it might overflow. Open the cap bit by bit to allow the air to escape.   

NZ Olympic Athletes 2020

 Hi Everyone

Today i'm going to be showing yous what we have been working for the last week. We have been learning about the athletes that have attended the Olympics in 2020. Here is the slide.

BYE!!!

Science!

 What were doing: Were doing chilli tasting 

What is the name of the chemical in chillis that make them hot? 

1. capsicnoid 

The name of the five most hottest chillis in the world? 

1. Carolina reaper 

2.  Ghost pepper 

3. 7 pot pot primo

4. naga viper 

5. 7 pot doughlahgh

Name five countries where chillis are grown? 

1 Mexico 

2. China 

3. Turkey 

4. Indonesia 

5. India 

How does a scovle scale work? 

Scoville heat units, also known as SHU is simply a measurement of the number of times capsaicin needs to be diluted by sugar-water. The number of Scoville Heat Units (SHU) in a pepper or even hot sauce indicates the amount of capsaicin present. The higher the Scoville rating, the hotter the pepper.

Aim: To see which is the best way to cool down the hot chillie taste in your mouth when eating chilli.

Hypothesis: I think that by using Milk I will be able to cool it down.

Equipment: 

1. Milk

2. Water

3. Coca Cola 

4. Tasting cup 

5. Chilli 

Method: 

1. You will work in groups of three for this experiment. Each person in the group will use one of the drinks with the chilli. you will then swap results in the group so that everyone has the same results. 
2. Each member of the group needs to have their own tasting cup. This will be used for putting the deffrent liquids in as we cool off the chilli in our mouths. 

3. place the chilli in your mouth 

4. after 10 seconds you will drink the liquid that you have in your cups. As you can do this you will complete a results chart 

You will be recording the following using yes or no 

1. The effectiveness of the liquid immediately 

2. The effectiveness of the liquid after 10 seconds
