science

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
