SSA Review - Big Idea 8 and 9 - properties and changes in Matter

During station 1 Davian's group crushed the sugar cube. How does crushing the sugar cube speed up the rate of dissolving?

• by stirring the water

• by changing the temperature of the water

• by increasing the surface area of the sugar exposed to the water

• by decreasing the surface area of the sugar exposed to the water

Mario's group went to station 1 and followed the same procedures as Davian's group. At the end of the lesson the two groups compared thier results. Why is it important to compare the results of the same experiment?

• to prove thier answers correct

• to check the reliabliity of thier data

• to change their data to match each other

• to show they followed every step of the scientific method

When Ms. Jones graded Mario's group's station 2 activity, she found two errors in thinking. What were the two errors Ms. Jones found

• boiling is a physical change and burning is a chemical change

• crushing is a chemical change and rusting is a physical change

• tarnishing is a physical change and evaporation is a chemical change

• digesting is a physical change and condensation is a chemical change

• container 1

• container 2

• container 3

Kimba pours 14 grams of sugar into a jar filled with 500 mililiters of water. She thoroughly stirs the sugar and water. Which change most likely occurs to the sugar when it is added to the water?

• The sugar completely dissolves in the water.

• Te sugar floats on the surface of the water.

• The sugar dissolves to form a new substance.

• The sugar causes water to become a new substance.

Candace was asked to compare the masses of four blocks that were all the same size, but made if different materials. She used a balance to compare the masses of two blocks at a time. Candace repeated this process three more times with different pairs of blocks and recorded her observations. Which list shows the blocks in order from least to greatest mass?

• Blocks P, M, L, N

• Blocks P, L, M, N

• Blocks N, M, L, P

• Blocks N, L, M, P

Ms. Underwood pushes the mower around the yard, cutting the grass. When she stops the mower, she removes the grass catcher and pours the clippings into the compost pile. The grass will eventually decompose and can be mixed into the garden. Finally, Ms. Underwood sweeps the grass clippings off the sidewalk. Which statement is true?

• Cutting the grass is a physical change

• composting the grass is a physical change

• sweeping the sidewalk is a chemical change

• pushing the lawnmower is a chemical change

Colin was using a pan balance. He placed three boxes on the pan balance as seen. Which of the following is a true statement about the boxes based on your observations of the pan balance?

• box 1 has less mass than box 3

• box 2 has greater volume than box 3

• box 1 and 2 have the same amount of mass

• boxes 1 and 2 have a combined greater mass than box 3
