The investigation outlined above (“Does more rain make healthy bison babies?”) is what type of investigation?
Experimental investigation
Not a type of scientific investigation
Comparative investigation
Descriptive investigation
Does the data from the investigation support their hypothesis?

Yes, the data shows that when there is more rain fall the weight of the calves increase.
Yes, the data shows that when there is less rain fall the weight of the calves increase.
No, the data shows that when there is more rain fall the weight of the calves increase.
There is no way to tell if the hypothesis is supported by this data.

Solids are usually more dense than liquids because...
The atoms are usually larger and further apart and can flow past each other.
the atoms are usually larger and closer together in a fixed shape.
The atoms are usually smaller and closer together in a fixed shape.
The atoms are usually smaller and further apart and can flow past each other.

What are the steps when finding volume using a graduated cylinder?
1) Put graduated cylinder on a flat-level surface 2) Get down to eye level with liquid 3) Measure from bottom of meniscus
1) find the mass of the empty cylinder 2) add the liquid and find the mass of the liquid and cylinder 3) subtract the empty mass from the mass of the liquid and cylinder
1) Find the volume of the liquid before adding the object 2) add the object to the water and measure the new volume 3) subtract the starting volume from the volume of the liquid and the object.
