Danny is trying to figure out how fast sugar crystals can dissolve in water. He has already tested crystals of table sugar by just pouring packets of sugar into a ball room-temperature water.
Which should Danny try next if he wants to make the sugar dissolve faster?
All of these
Cool the water
Use larger crystals
Stir the water
In an experiment, Kyle wants to test how stirring affect the rate at which sugar dissolves into water. He fills 3 glass beakers with water. Before each test he will pour sugar into each beaker. In beaker 1, he will not stir the substances. In beaker 2, he will stir the substances slowly. In beaker 3, he will serve the substances quickly. As he stirs, he will use a stopwatch to time how long it takes to sugar to dissolve into the water.
Before he begins the experiment, what should Kyle do?
Place beakers 1 and 2 on a hot plate for 5 minutes so they are warmer than beaker 3.
Check that beakers 2 and 3 are wider than beaker 1 so water does not spill when stirring.
Find two different size spoons to use for stirring the substances in beakers 2 and 3.
Measure the samples of sugar so the amounts in beakers 1, 2, and 3 are the same.
Susie is drawing with a blue pencil when she accidentally breaks it.
Which of the following statements about the pencil is true?

The total mass of the pencil increased when it was broken.
The pencil did not undergo a physical change when it was broken.
Before scientist do an experiment they tell what they think will happen.
