The rattle on a Rattlesnake is an adaptation that:
-
attracts a mate.
No. Snakes do not hear airborne sounds, so another snake would not hear the rattle. -
attracts mice and other prey animals.
No. Like other animals, mice would be frightened away by the rattle. -
warns predators to stay away.
Yes! The sound of a Rattlesnake's rattle is a warning that the snake will bite to defend itself. -
helps the snake hide.
No. There is nothing about the rattle that would serve as camouflage or help the snake hide.

Baking a cake is an example of:
-
A physical change
Partly right. Some of the changes involved in baking a cake are physical changes. -
A chemical change
Partly right. Some of the changes involved in baking a cake are chemical changes. -
Both
Yes! The process of baking a cake involves many changes. Some, such as water evaporating and sugar melting are physical changes. Others, such as baking powder reacting cause a change in the chemical formulas, indicating a chemical change. For more on this, read Changing How We Look at Changing -
Neither
No. There are many changes involved in baking a cake.

When this cannon fires, cannon and the cannon ball both move, but the cannon ball moves much farther and faster than the cannon. Why?
-
The cannon ball is smaller.
No. While smaller size means a little less air resistance, that is not enough to cause the difference. -
The wheels on the cannon are stuck.
No. Even with the wheels moving freely, the cannon ball will still move much faster and much farther. -
The cannon ball is round.
No. While the round shape means a little less air resistance, that is not enough to cause the difference. -
The cannon ball weighs less.
Yes! According to Newton's Second Law of Motion, the more mass an object has, the less it will be affected by a force. Newton's Third Law of Motion tells us that the cannon and the cannon ball will both be pushed by the same amount of force, but since the cannon is much heavier (more mass), it will not move as fast or as far.If the cannon was made of very light weight plastic, so that it was much ligher (less mass) than the cannon ball, then the cannon would move farther and faster.

Which of the following observations is scientifically testable?
-
Honeybees are good insects.
No. "Good" is a generic term that could mean many different things in different situations. It is an opinion, not a testable property. This statement is NOT scientifically testable. -
Honeybees are important insects.
No. "Important" is a generic term that could mean many different things to different people. It is an opinion, not a testable property. This statement is NOT scientifically testable. -
Honeybees are pretty insects.
No. Some people might think that a honeybee is pretty, and some people might not. It is an opinion, not a testable property. This statement is NOT scientifically testable. -
Honeybees are not insects.
Yes! While this statement is not correct, it is scientifically testable. You could examine the bee to see that it does fit the definition of an insect. This statement is IS scientifically testable.

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.
