When a scientist makes a new discovery, other scientists usually do exactly the same experiment. Why?

  1. They want to get part of the credit.

    No. While replicating an experiment is very important, the scientists who do it usually don't get much credit for their work unless they discover an error in the original experiment.
  2. Repetition is part of the scientific process.

    No. Repetition is when scientists repeat their own experiment several times, not when other scientists do the same experiment.
  3. They think they can make changes to improve the experiment.

    No. By doing exactly the same experiment, they are not changing anything. Instead, they are replicating the experiment as closely as possible.
  4. Replication is part of the scientific process.

    Yes. By replicating the experiment, other scientists can help verify that the results are accurate. There is always a possibility that there was some unnoticed influence on the original experiment, and replication can help spot that.

Which of these is NOT a form of energy?

  1. Light

    No. Light is a form of kinetic energy.
  2. Thermal

    No. Thermal is a form of kinetic energy.
  3. Fire

    Yes. Fire is a chemical reaction that can produce forms of energy such as light, heat, and motion, but fire is NOT a form of energy.
  4. Motion

    No. Motion is a form of kinetic energy.

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?

  1. 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.
  2. 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.
  3. 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.
  4. 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.

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?

  1. Attraction

    No. The slight attraction between the water and the glass is not enough to balance the pull of gravity.
  2. 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.
  3. Surface tension

    No. The water tension at the surface of the water would not balance the force of gravity.
  4. 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.

This is the mineral galena. What type of luster does it have?

  1. Vitreous

    No. A vitreous luster means that the mineral looks glassy. Galena does not look like it is made of glass.
  2. Shiny

    No. Shiny is not a type of luster.
  3. Metallic

    Yes! A metallic luster means that the mineral looks like it is made of metal. Galena reflects light in the same way that a piece of metal does. If a mineral looks like it is made of metal, it has a metallic luster.
  4. Silver

    No. Silver is a color, not a type of luster. Luster is the way that a mineral reflects light, not is color.
