During an experiment, students observed that an unknown substance was a fine, white powder that reacted to vinegar, was soluble in water, and did not conduct electricity.
Based on the chart, which is the unknown substance?
Table Salt
Chalk
Sugar
Flour
Baking Soda
Students poured water and sugar together in a cup. Based on the picture, which model best represents the number and arrangement of the water and sugar particles after it was mixed? PAY ATTENTION to the number of particles.
Looking at the picture, organize the minerals into either magnetic or not magnetic.
The images below show water particles in different phases. Select the correct lettered images of water particles and place the letters in the appropriate boxes to develop a model for solids, liquids, and gasses.
Gas
Liquid
Solid
The diagram below represents the setups a teacher showed students for an investigation about a closed system. In Setup 1, the teacher placed a balloon over the top of a container that has some water in it. The total mass of this closed system was 460 grams. In Setup 2, the teacher used appropriate safety equipment and followed all safety procedures as the container was placed on a stand above a heat source for five minutes. Why did the balloon inflate?
The teacher added a tube for the balloon
The teacher added a heat source and turned the water into a gas
The teacher raised the container so it was higher
The teacher added more water for the balloon
A teacher did a demo lesson for her students with a balloon. Setup 1 and Setup 2 are a CLOSED system. Using the picture, complete the bar graph to represent the masses (in grams) of this closed system in Setup 1 and Setup 2 by coloring in how much each one weighs (mass). The bar graph does not have to look perfect.
A cook has containers with several white powders in them. She cannot tell the powders apart
by looking at them. Which of the following would NOT be useful to help her?
touching each of the powders for its texture
Looking at the color.
test if they dissolve in certain liquids
smelling the containers

Maxine makes a claim that a new substance formed as a result of mixing these two substances.
What evidence from the data best supports this argument?
Identify an example of each of the three states of matter present when the candle is burning.
Solid
The hard wax of the candle
Liquid
The melting wax
Gas
The fire/flame
Read each fact. Decide if that fact is TRUE or FALSE.
when matter changes it can be destroyed
When you see a gas, it is a chemical reaction.
Melting is a type of physical change.
Love and Energy are Matter
Air is not matter because I can't see it
I need to add cold to get from a liquid to a solid
