Which organ produces insulin to control blood sugar levels?
-
Liver
No. The liver produces bile, which digests fats. -
Gall Bladder
No. The gall bladder stores the bile produced by the liver. -
Pancreas
Yes! The pancreas produces insulin. -
Thyroid
No. The thyroid produces several hormones which control growth and metabolism, but it does not produce insulin.

This snow fell when the temperature outside was 39°F. How can you get snow when the temperature is above freezing?
-
The wind made it feel colder, allowing it to snow.
No. While wind chill can make it feel colder, it does not actually make it colder. -
It was colder in the clouds where the snow formed.
Yes. Even when air temperatures at the surface are above freezing, the clouds can be much colder. If the air at the surface is not too warm, the snow can reach the ground without melting. -
Rain froze into snow when it hit the ground.
No. Freezing rain forms ice, not snow. Light, fluffy snow flakes form as they fall through the air, not after they hit the ground. -
This is really hail instead of snow.
No. Hail is made of large chunks of ice, not tiny flakes.

I wanted to test different amounts of fertilizer to see which was best for growing grass. I mixed water with different amounts of fertilizer, and then added sodium polyacrylate to change it into a gel. Then I sprinkled the grass seeds on top, and waited for them to grow.
I really need a control group for this experiment. What would I use for a control?
-
Water, fertilizer, and grass seed, without any sodium polyacrylate.
No. For the control, we want to skip the thing we are testing for. We are not testing changes caused by the amount of sodium polyacrylate. -
Water, sodium polyacrylate, and grass seed, without any fertilizer.
Yes! We are testing to see how different amounts of fertilizer change the growth of the grass. The amount of fertilizer is the variable we are testing, so the control group should not have any fertilizer. -
Water, sodium polyacrylate, and fertilizer, without any grass seed.
No. For the control, we want to skip the thing we are testing for. We are not testing changes caused by the amount of grass seed, and we know that no grass will grow if we do not have any seeds. -
Sodium polyacrylate, fertilizer, and grass seed, without any water.
No. For the control, we want to skip the thing we are testing for. We are not testing changes caused by the amount of water.

Why are trees an important part of the water cycle?
-
Trees need water.
No. While trees do need water, that is not why they are part of the water cycle. -
Transpiration
Yes! In order to get nutrients up to the top of a tree, it has to let water evaporate from its leaves. This process is called transpiration. One tree can put hundreds of gallons of water into the air as water vapor every day. -
Trees help prevent erosion.
No. While trees can help prevent erosion, that is not why they are part of the water cycle. -
Condensation
No. Trees are not a major source of condensation.
