I agree with you, Ana.
In my opinion, the more Your opinion can be used
quantity of glycerine is as the hypothesis of our
used, the longer the time experiment. I suggest that
it takes for the bubbles we only use dishwashing
to burst. liquid to make our soap
solution.
We should not waste time.
Let's conduct this experiment.
1. Aim
To investigate the relationship between the quantity of glycerine
and the time taken for the soap bubbles to burst.
2. Problem statement
Does different quantity of glycerine affect the time taken for
the soap bubbles to burst?
3. Hypothesis
The more quantity of glycerine is used, the longer the time taken for the
soap bubbles to burst.
4. Determining the variables
• manipulated: quantity of glycerine.
• responding: time taken for the soap bubbles to burst.
• constant: type of dishwashing liquid, volume of water, size of the
bubbles produced, and the speed of surrounding wind.
