hypothesis: Billy and Bob want to know if the amount of baking soda added to vinegar will affect the height a rocket will launch. They will measure the height of the rocket launch in meters
<h2>The hypothesis could be</h2><h3>The height a rocket will launch is directly propotional with the amount of baking soda added to vinegar.</h3>
Explanation:
A hypothesis is a supposition based on limited information. It's the starting point of a research,
So, in this case, Billy and Bob want to know if the amount of baking soda added to vinegar will affect the height a rocket will launch, their hypothesis is based on that.
The hypothesis could be
The height a rocket will launch is directly propotional with the amount of baking soda added to vinegar.
Such hypothesis is relating both variables, specifically, it's stablishing a direct proportion, which means, the more soda with vinegar, more height will be.
