I put a paper plate on top of a glass of water. I turned it over, and the water stayed in the glass.
The weight of the water is pushing down on the paper plate, but the plate stays in the glass because the pull of gravity is being balanced by another force. What is that force?
-
Attraction
No. The slight attraction between the water and the glass is not enough to balance the pull of gravity. -
Air pressure
Yes! Because the plate is keeping outside air from entering the glass, outside air pressure is keeping the plate in place. As long as the outside air pressure is enough to balance the weight of the water and the plate, it will stay in place. If you made a small hole in the glass to let outside air get in, that would unbalance things, and the water would fall out. -
Surface tension
No. The water tension at the surface of the water would not balance the force of gravity. -
The weight of the paper card
No. Gravity is pulling down on the paper plate and the water. The weight of the paper does not help balance the force of gravity.

Which part of the food web do these termites belong to?
-
Producer.
No. A producer captures energy from sunlight, and stores it as food. To do that, the organism needs to contain chlorophyll. -
Primary Consumer.
No. Primary consumers eat producers. Termites do not eat live plants. -
Secondary Consumer
No. Secondary consumers eat other consumers. This butterfly does not eat animals. -
Decomposer
Yes! Termites are one of the few animals that can digest the cellulose from dead wood, thanks to special bacteria that live inside them. That makes termites very important as decomposers, but it also means that they can be a problem when we build things from wood.

This is a lichen, which is actually a fungus and an algae living together. As it grows, it produces chemicals which dissolve some of the rock it grows on. This is an example of:
-
Erosion
No. Erosion means that the pieces of rocks are being carried away. The lichen is dissolving the rock, but not carrying it away. -
Weathering
Yes! Lichens cause quite a bit of weathering in rocky areas. -
Both erosion and weathering
No. The rock is not being moved, so it is not erosion. -
Neither erosion nor weathering
No. As the lichen dissolves the rock, that is an example of weathering.

These are the four stages of a mealworm's life cycle. What kind of life cycle is it?
-
Incomplete metamorphosis
No. For an incomplete metamorphosis, there are only three stages: egg, larva, and adult. The young also look very similar to the adults. The mealworm larva looks very different from the beetle. -
Complete metamorphosis.
Yes! For a complete metamorphosis, the animal goes through four stages: egg, larva, pupa, and adult. -
Full metamorphosis.
No. There is no life cycle called full metamorphosis. -
Partial metamorphosis.
No. There is no life cycle called partial metamorphosis.

Which of the following is a major characteristic of hurricanes?
-
Low barometric pressure
Yes. Hurricanes always have very low barometric pressure. -
High barometric pressure
No. Hurricanes always have very low barometric pressure. -
Winds blowing towards the shore.
No. The direction of the winds depends on the location of the storm, relative to the shore. Depending on location, hurricane winds can blow towards shore, away for shore, or parallel to the shore. -
Winds blowing away from the shore.
No. The direction of the winds depends on the location of the storm, relative to the shore. Depending on location, hurricane winds can blow towards shore, away for shore, or parallel to the shore.
