When Nancy and I moved from Florida to our new home in Utah, we found that many of the flowers we grew in Florida would not grow well here. Why?
-
The soil is different.
This is part of the answer. The soil here is mostly sand, and is very alkaline. The soil in Florida had much more organic matter and was more acidic. Plants that need rich soil do not grow well here. -
The climate is different.
This is part of the answer. The climate in Utah is very different from Florida. The winters are MUCH colder (down to -20°F) and the summers are MUCH hotter (up to 125°F). The climate here is also much drier. When we lived in Jacksonville, FL, we got about 52 inches of rainfall each year. Here in Utah, we only get about 14 inches of rainfall each year. Some of the plants from Florida can grow here, but the ones that cannot stand the cold, heat, and dry conditions do not. -
The animals are different.
This is part of the answer. The wildlife here is much different from the animals in Florida. There are insects here that eat plants that were not bothered by Florida insects. There are rock squirrels, western pocket gophers, jack rabbits, mule deer, and many other animals here that love to eat many kinds of flowers. Plants that do not have a bitter taste, spines, or other ways to discourage animals do not do well here. -
All of the above.
Yes! All of the answers are correct. When you take an organism from one environment and put it into another, you may see different results. If the organism is not adapted for the new environment, it may die or not grow well. If it is very well adapted to the new environment, it may take over, crowding out some of the native organisms.

The wood in this pile will be reduced to this much ash when it is burned. What happens to the rest of the mass from the wood?
-
It was converted into energy.
No. Burning does not convert matter into energy. -
It evaporated.
No. While any moisture in the wood may have evaporated, wood itself does not evaporate. -
It was converted into water and carbon dioxide.
Yes! Burning converts the cellulose in wood into water vapor and carbon dioxide. The white ash that is left behind is made up of the minerals and nutrients which were taken in by the plant's roots. -
The matter is still there. It just got smaller.
No. If all of the matter was still there, the mass and weight would still be the same. The ash is much lighter than the wood, because the water vapor and carbon dioxide are now part of the air of the room. Still, if we could weigh all of the ash, water vapor, and carbon dioxide, the total mass would still be the same.

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.

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

This is a simple chart showing how energy flows through some of the parts of a food web. For example, the arrow from the grass to the grasshopper shows that the grasshopper gets it energy by eating the grass.
The hawk gets its energy by eating the water snake, but there is no arrow leading from the hawk. What should the arrow from the hawk point to>
-
Egret
No. The egret does not eat hawks. -
Carrion
Yes! Carrion is dead animals. When the hawk eventually dies, flies will get their energy by eating the dead body. You could also draw arrows from all of the other animals to carrion. -
The Sun
No. The Sun is not on the chart, and The Sun does not get its energy from the hawk. -
There should not be an arrow leading from the hawk.
No. Energy cannot be destroyed. It always goes back into the system.
