What is the aim of your investigation?
To see how ______________________________________affects _____________________________________________
What is your hypothesis?
As the size of the jelly pieces ______________ the time taken for the jelly to dissolve ______________ .
Other Answer Choices:
decreases
changing the size of jelly pieces
the time taken for the jelly to dissolve
increases
the size of the jelly piece
5
Explain your hypothesis.
For piece of jelly to dissolve the water ______________ have to collide with the __________ particles.
Only the jelly particles on the ____________surface of the jelly can ____________ with the __________ particles.
The jelly particles that are not on the outside cannot dissolve.
If the number of jelly particles that are on the outside increases then the time taken for the jelly to dissolve will decrease.
Smaller pieces of jelly have a larger surface area to volume ratio (more of the particles are on the outside).
Other Answer Choices:
particles
water
jelly
collide
outside
