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.

These cells have a cell wall. What does that tell us?
-
These are young cells.
No. Even new cells can have a cell wall. -
These are plant cells.
Yes! Plant cells are surrounded by a cell wall, which provides structure and protection. -
These are animal cells.
No. Animal cells do not have a cell wall. -
These are dead cells.
No. Being alive or dead does not change whether a cell has a cell wall or not.

I used this piece of quartz to scratch a piece of glass. What was I testing?
-
Streak
No. To test streak, you rub the mineral on a white tile, to see its color when it is powdered. -
Fracture
No. Fracture is one way that minerals can break. I am not breaking the mineral. -
Hardness
Yes. Hardness is measured by scratching other substances, such as your fingernail, copper, and glass. This quartz scratches the glass, which tells us it has a hardness or 5.5 or more. Actually, the hardness of quartz is 7, quite a bit harder than glass. -
Cleavage
No. Cleavage is one of the ways that minerals can break. I am not breaking the mineral.

Which part of the food web does this roadrunner 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. In spite of what you may have seen in cartoons, roadrunners do not eat plants or bird seed. -
Secondary Consumer
Yes! Secondary consumers eat other consumers. Roadrunners are predators, and eat lizards, snakes, mice, and many other small animals. -
Decomposer
No. Roadrunners may occasionally scavenge freshly killed animals, but they are not decomposers.
