Pick something that is NOT matter. Explain why it is not matter.
Energy, force, feelings, thoughts, etc
because matter has to be something that takes up space and has mass.

3. It shows how the atoms in a solid can move easily around one another.
4. It shows how the atoms in a gas can fill a space.
4. It shows how the atoms in a gas can fill a space.

A student wanted to conduct an investigation with a solid that had a mass of 50 grams. She wrote her observations in this data chart.
What other data is needed to show that mass was conserved when the matter changed phases?
1. She needs to measure the mass of the liquid and the solid at 4 minutes
2. She needs to measure the mass of the liquid at 10 minutes
3. she needs to measure how long it takes to change the liquid into a gas.
4. She needs to look to see if the solid and the liquid look like the same amount.
2. She needs to measure the mass of the liquid at 10 minutes

A limitation of this model is that it does not show:
1. How the atoms in matter might look in various phases
2. The actual size of atoms
3. How liquids, solids, and gases differ in how they fill the container
4. How the atoms in a liquid may move more easily to flow past one another.

What was the student's testable question?
1. What is the effect of different substances on temperature?
2. What is the effect of whether something is a liquid or a solid?
3. What is the effect of temperature on phase changes in different substances?
4. What is the effect of different substances on solids, liquids, and gases?

A student conducted an investigation where liquid was transformed to a gas. Look at this data table and give a possible explanation as to why it appears that matter was not conserved.
When liquid was heated, the gas began to evaporate; the mass was less than it was before heating because the mass of the gas could not be measured.

How does energy transform matter?
Use science words in your answer.
Energy transforms matter by causing it to change phase. Heat energy causes matter to go from a solid to a liquid to a gas. Removing heat energy causes the matter to cool, returning it to a liquid or a solid.

What would you do to separate salt, water, and small pieces of metal which were mixed together?
Use a magnet to separate the metal and then evaporate the water (using heat energy) to a gas leaving the salt behind.

Which set of models best demonstrates matter with the same volume and different mass? Select the best answer:
Set A

In this investigation, what would you expect to happen if heat energy was removed? Select the best answer.
1. The temperature would increase and gas might change phase to liquids.
2. Solids might change phase to liquids.
3. The mass would increase.
4. The temperature would decrease and the gas would change phase to a liquid.
4. The temperature would decrease and the gas would change phase to a liquid.

Which of the following models demonstrates a mixture that is a solution and which one demonstrates a mixture that is not a solution?
*Bonus 200 points if you can identify an advantage of the model and a limitation of the model*
A - Mixture that IS a solution because the particles are evenly distributed showing something has been dissolved.
B- Mixture that is NOT a solution because the particles have not dissolved.
