Science Week 8

Today in science we did a science experiment and made sherbet.

Aim: To learn about the makeup of different white powders.

There are  a number of different white powders in our everyday life. Some of these are harmful and others are not. Test the four white powders listed to see which one has been found at the airport.

Here are some examples of everyday kitchen white powders.

Flour, Cornflour, Sugar, Salt, Baking Soda, Baking Powder, Icing Sugar, Tartaric Acid

Citric Acid, Gluten Free flour

You will be given a small amount of 4 white powders on your cardboard. On the black cardboard using a magnifying glass look at the powders.

Look at them under your magnifying glass and record what you see. 

These are the four powders we will be using. Upload a photo of each powder. 

1.  Cornflour
2.  Baking Soda
3.  Salt
4.  Sugar 

Before you add the iodine, vinegar or water you will need to divide each powder into 3.

Materials

1.  Iodine
2.  Water
3.  Vinager
4.  Paper
5.  Pen
6.  Chromebook 
7. Corn flour
8. Sugar
9. Salt
10. Baking soda
11. A ruler


Steps

1. Get in a group of 4
2. Make 4 squares on the piece of paper with a ruler
3. Put salt, sugar, baking soda, corn flour / put each of them on their own square.
4. Put all the powders in 3 small groups but keep them in the square the big pile was in.
5. Put one liquid on 1 group of each powder, my group started on Iodine, then vinegar and we ended with water
6. Write down what happened

Findings:

	Sugar	Salt	Baking Soda	Cornflour
Appearance	Like tiny cubes	Little tiny crystals	Smooth	Cube and smooth at the same time
Texture	Tiny hard cubes	Kind of hard but then not	Also smooth	Soft but also weird
Smell	Like nothing really	Kind of bad	Disgusting	Weird
Iodine	brown,	light and dark grey, wet,	Brown and yellow, looks kinda weird	Going hard, Still mostly white
Water	Kind of light grey and dark grey	harder, crystal like, white	white, looks the same, bubbly also	oobleck
Vinegar	light grey	Clear, harder	darker than it started	kind of dark and then not

Write a paragraph about your findings. 

I think it was really cool to see what reacted to what and also what didn't react. I think the one that reacted the most was the water and baking soda because it went all bubbly and it looked cool.

Making Sherbet

Once you have completed your blog and cleaned up all your equipment you can make sherbet.

Using the following recipe you can make sherbet.

Sherbet recipe

1/2 tsp icing sugar
1/4 tsp -baking soda.
Put all ingredients into a zip lock bag, stir, and enjoy.

Materials:

1.  Zip lock bag

2.  Baking soda

3.  Icing sugar

4.  Citric acid

5.  powder drink crystals

6. Hands to shake the bag

Steps

1. Put all the powders in the zip lock bags

2. After you got all your ingredients go back to your table you did the powder experiment before we made the sherbet

3. Shake the bag until everything mixed up

4. Then enjoy

Findings: 
It was pretty easy to make and it was also pretty good but I could taste the baking soda.
