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.

Review Matter-4 | practice |

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

The "strings" in a stalk of celery are made up of xylem and phloem. Which part of your body comes closest to serving the same function?
-
Skeleton
No. Your skeleton provides support and protection. In plants, the cell wall provides support and protection. -
Intestines
No. Your intestines allow you to absorb nutrients from your food. Plants make their own food, so they do not need a digestive system. -
Nerves
No. Your nerves carry signals to let the parts of your body communicate. They carry messages for your senses, to move your muscles, etc. Instead of having nerves, plants release chemicals that signal other parts of the plant. -
Blood Vessels
Yes! Your blood vessels carry water and nutrients to different parts of your body. In plants, the xylem is made up of tubes that carry water and some nutrients from the roots upwards to other parts of the plant. The phloem is made up of tubes that carry the sugar produce by photosynthesis to other parts of the plant. While they work in very different ways, your blood vessels serve basically the same function (carrying water and nutrients) as the xylem and phloem in plants.

Which position would the Moon be in when it is a full moon?
-
A
No. This would be a half moon, with the half towards the Sun in light, and the half away from the Sun dark. -
B
No. This would be a new moon. The entire lighted side of the Moon is facing away from the Earth, so the entire side of the Moon that we can see would be dark. -
C
No. This would be a half moon, with the half towards the Sun in light, and the half away from the Sun dark. -
D
Yes! The side of the Moon that is facing the Sun is also facing us. That entire side would be illuminated (unless the alignment was right for a lunar eclipse.)

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.
