Aim: To see which chemical
the mix creates the most gas.
Hypothesis: (What do I think will happen)
I think that the vinegar will not make the balloon go up or will not make it go higher, so I think that the other 3 teaspoons of baking soda will make the reaction better and more fluent.
Materials:
- Vinegar
- Bottle
- Balloon
- Baking soda
- Soda
- Salt
Steps:
- Measure half a cup of vinegar then pour it into the bottle.
- Then you will need to measure three tea spoons of baking Soda then tip it into the bottle.
- Then you need to pour half a cup of soda.
- Then you need to get do three tea spoons of Salt.
- Blow the balloon up then put the balloon at the top of the bottle.
- Secondly you shake the bottle a little bit to get the bubbles pumping
- Then the balloon will start to blow up.
- Then you measure one balloon to the other.

Kia ora Aisa, you have worked really hard to complete today's experiment and also to complete your report and post it on your blog, I am impressed with your dedication, well done. You have included your hypothesis, all of the materials, an excellent image and also you have completed your findings. You need to add in a CONCLUSION and also when you are writing the steps you need to put a verb at the start of the sentence. For example: Step 1: Put half a cup of vinegar into the bottle. Step 2: Put three teaspoons of the Baking Soda into the balloon.
