Aim: To see which chemical 
mix creates the most gas.

Hypothesis: (What do I think will happen)

1.

Materials: yeast experiment

1. balloon
2.  sugar
3.  yeast
4.  warm water
5.  fan ole
6. bottle

My hypothesis I don not think it would rise because I is a bad combination of yeast and water

grab a empty bottle take off the lid pour 2 tea spoons of yeast into the bottle and one tea spoon on sugar into the balloon using a fhanule next ad a little bit of warm water and then attach the balloon to the top and now wait 

2

Materials: backing soda and vinegar

1.  backing soda
2.  balloon
3.  empty bottle
4.  fanoule
5.  vinegar

 Steps: 

grab an empty bottle take off the lid use the funnel  put  backing soda into the bottle then put half a cup of vinegar into a balloon using the funnel then attach the balloon to the top and wait

Hypothesis

I think it would work because of the combination of the vinegar and the backing soda would make heaps of gas the  gas would rise to the top to make it blow up

3

Materials: soda water and salt

1.   soda water
2.  balloon
3. funnel
4. bottle
5. salt

 Steps:

gap an empty bottle take off the lid and ad soda water to the bottle using a funnel then grab a balloon using a funnel pot the salt into a balloon then attach the balloon to the bottle and then wait

Hypothesis

We new it could work because it would release carbine dioxide.

My images:

Findings:
the first experiment had lots of bubbles and a medium amount of air in the balloon 
the 2nd experiment had a small amount of bubbles but it was the biggest balloon with the most air and the 3rd balloon  had a medium amount of bubbles and a tiny amount of air inside of the balloon My new hypothesis is that the bottle with the less bubbles inside has the most air inside of the balloon

	Balloon 3 ( 3 tsp baking soda, ½ cup vinegar)	Balloon 2 ( 3 tsp salt, ½ cup soda)	Balloon 1 ( 2 tsp yeast, 1 tsp sugar )
Balloon Size (cm)	15 cm	19 cm	8 cm
Bubbles	medium amount of bubbles	small amount	lots of bubbles

conclusion 

I liked all the experiments because I showed how you can have the same gas but with different ingredients it can show different results to your answer and I help us with team building

how to make chocolate chip cookies

       how to make chocolate chip cookies

200g butter
1 cup Chelsea White Sugar
1 cup Chelsea Soft Brown Sugar
2 eggs
2 tsp vanilla essence
3 cups flour
pinch of salt
1 tsp baking powder
2 cups chocolate chips

Melt butter, and add both sugars and cream these together. Beat in the eggs and vanilla then mix in the dry ingredients. Roll into medium sized balls, making sure the mixture is not too wet! Put on a well greased baking tray. They shouldn't spread too much so flatten slightly. Bake at 180° for 8-10 minutes.

Tip: you can easily half this recipe. Or roll half into a log, wrap in cling film and freeze. Cut into 15 pieces while still frozen and bake.

How to make slime

                  How to make slime

1. In one bowl mix 1 oz. glue (about ¼ of the glue bottle) and ¼ cup water. If you want colored slime, add food coloring to the glue and water mixture. Lift some of the solution out of the container with the stir stick and note what happens.
2. Add ¼ cup of borax to the glue and water mixture and stir slowly.The slime will begin to form immediately. Lift some of the solution with the stir stick and observe how the consistency has changed from Step 1.
3. Stir as much as you can, then dig in and knead it with your hands until it gets less sticky. This is a messy experience but is necessary because it
   allows the two compounds to bond completely. Don’t worry about any
   leftover water in the bowl; just pour it out.
4. When not in use, store the slime in a plastic bag in the fridge to keep it
   from growing mold.

                             Hi readers this is a Blog posts about science hope you like it.

To day we needed to wire about what is a chemical in the name we got giving and we got tolled to                                                          writ if it is a solid liquid or a gas

Name	Chemical	image	Solid liquid gas
lemon juice	citric acid		liquid
salt	Sodium chloride		solid
sugar	sucrose		solid
vinegar	Acetic acid		liquid
lemon bubbles	carbon dioxide		liquid
onion gas	S-oxide		gas
baking soda	Sodium bicarbonate		solid
milk	enzymes		liquid
cornflour	Maize starch		solid
Banana	Potassium		solid

Today we learnt about what different chemical's there is in different Solid liquid and gas.Not not many people know what to do because it was a new thing to us .It was so surprising by there being so much chemical's in most of my favorite food.Like banana has potassium and cornflour has maize starch.Most people did not know about all of chemical's I there drink.most people know at there is a lot of food with chemical's in it.In most food and drinks there is a lot more chemical's in them then i wrote down. Some people know the answer straight away. Chemicals make up everything in existence, from the air we all breathe to the stars in the sky.
