Form a hypothesis:
Does water temperature affect the dissolving rate of Kool-Aid.
If temperature is increased, then Kool-Aid will taste better
If temperature is increased, then Kool-Aid will dissolve faster
If red flavor is used, then it will taste better & be colder
If orange flavor is used, then it will dissolve faster
2
I want to study if the water temperature affects the dissolving rate of Kool-Aid.
Controls?
amount of water used
size of container
water temperature and dissolving rate
flavour of Kool-Aid
3
What is the
1ST
step of the scientific method?
Analyse the data
Make an observation
Form a hypothesis
Do research
4
Form a hypothesis
for: Calcium increases bone strength.
If calcium is taken daily, then you are healthy
If bone are strong, then calcium is apart of your diet
If milk is not part of your diet, then your bones are weak
If calcium intake is increased, then bones will be stronger
5
Find DV
: I want to study if the water temperature affects the dissolving rate of Kool-Aid.
dependent variable: amount of water used
dependent variable: temperature of the water
dependendent variable: dissolving rate
dependent variable: flavour of Kool-Aid
6
Find DV:
Students want to test if adding miracle grow to the soil will affect plant height.
dependent variable: amount of water
dependent variable: plants' color
dependent variable: plant height
dependent variable: composition of the soil
7
Find IV:
I want to study if the water temperature affects the dissolving rate of Kool-Aid

Students want to test if adding miracle grow to the soil will affect plant height.
Hypothesis:

If miracle grow is added, then plants will grow taller
If miracle grow is added, then plants will be greener
