Pine trees do not have flowers. What structure do they have that servers the same purpose?
-
Needles
No. Pine needles are a kind of leaf. They are not used for reproduction. -
Cones
Yes! Pine cones produce pollen and seeds, just as flowers do in flowering plants. -
Fruit
No. Fruit are used for dispersing seeds, not for pollination. -
Buds
No. Pine tree buds produce needles. They are not involved in reproduction.

Which of the following is a difference between a meteor and a comet?
-
Meteors are mostly made up of ice.
No. Meteors are made up of rock or iron, Comets are mostly made up of ice. -
Only comets have a visible tail.
No. A meteor is a meteoroid that has entered our atmosphere. As it burns, it also produces a tail. -
Meteors seem to move faster because they are closer.
Yes. Meteors are entering our atmosphere, so they are much closer to us that a distant comet. That makes them seem to move much faster. -
Comets are smaller than meteors.
No. Meteors are small, often the size of a grain of sand. Comets are much larger.

In the Yeast and Sugar video, I added different kinds of sugar to bottles with yeast and warm water. One of the bottles was a control. What should have been in that bottle?
-
Just water
No. With just water, you are removing two variables, the yeast and the sugar. You only want to remove the independent variable.
-
Water and yeast
Yes! A control should be exactly like the others, but without the independent variable (the variable you are changing in the experiment.) In this case, the variable you are changing is the kind of sugar, so the control should have everything except for the sugar. -
Water and sugar
No. The yeast is not the independent variable, so leaving it out would not be correct. -
Water and salt
No. Adding salt would be adding a new variable, which is not correct.

Which part of your body comes closest to serving the same function as a plant's roots?
-
Mouth
Yes! The main functions for most plant roots is to anchor it in place and to take in water and nutrients from the soil. We do not need anything to anchor us in one place, but we use our mouth to take in water and nutrients. -
Feet
No. A plants roots anchor into in place, keeping it from moving. Your feet do not do that. -
Lungs
No. A plant takes in air through its leaves, not through its roots. -
Skeleton
No. Your skeleton supports your body and protects your organs. In plants, this is done by the cell walls. The cell wall around each cell of a plant make it stiff, supporting stems, leaves, flowers, and other parts of the plant.

Which of the following observations is NOT scientifically testable?
-
Butterflies have pretty wings.
Yes! Pretty is an opinion, and can vary from person to person, so it is NOT scientifically testable. -
Butterflies have six legs.
No. This could be tested by counting the legs of a variety of butterflies. -
Butterflies can sting like bees.
No. A claim does not have to be true to be testable. Examination of a variety of butterflies would show that they do not have stingers. -
Most butterflies drink nectar from flowers.
No. This could be tested by observing the feeding habits of butterflies.
Explain more about it.
If I said that butterflies did not have six legs, you could show me physical evidence by counting their legs. After counting the legs, the physical evidence would show that butterflies have six legs.
If I said that I don't think butterfly wings are pretty, you could show me wings that you think are pretty, but I might not agree with your opinion. "Pretty" is not something that we can measure. What is pretty to one person might not be pretty to another, so it is not a testable property.
