Thursday 10/24 - MM Mid Unit Test Mod - Elorde Tuliao | Library

Directions: Read and answer each of the questions below to show your science mastery.

2

Are these two liquids made from the same molecules? Why or why not? (2 pts)

A. Yes. Both of the substances are liquid, so they must be made up of the same molecules
C. No. Substance A is made of atoms and Substance B is made of molecules
D. No. The two substances have different properties, so they must be made of different molecules

Melanie looks in a reference book and finds the properties of 4 different liquids.

Fabian is doing an experiment to see if the ink in a black marker is a mixture or a substance. Fabian draws a dot with the marker on a paper and records what it looks like in his notebook. Then he places the left side of the paper in water. The water moves across the dot on the paper and Fabian records what happens to the dot.

2

Which model best represents the particles (molecules) in the water? (2 pts)

2

Which of these molecules is moving the fastest? (2 pts)

A. The molecules in the water used in the experiment
B. The molecules in the air around the experiment
C. The molecules in the paper used in the experiment

Criteria For Success

Claim: Short answer
Identify whether the marker ink is a substance or mixture
Evidence: Use evidence from the model (picture) to support your answer.
Describe what you see in the picture.
Reasoning: Explain your claim with details.
Explain why the marker ink is a substance or mixture.

4

Is the marker ink a mixture or a substance? Explain how you know. (4 pts)

Claim: The marker ink is a ____

Evidence: In the model, it shows

Reasoning: This means the marker ink is a _ because __________

Type your paragraph (at least 3 sentences!) below.

2

Which statement best explains what happened to the ink? (2 pts)

A. The water made the ink change color to red and blue
B. The water made the ink molecules stretch and get bigger
C. The water moved the blue ink molecules farther up the paper than the red ink molecules

2

Fabian created 3 different models of the molecules in the marker ink before the experiment. Which model is the most accurate (correct)? (2 pts)

Criteria For Success

Claim: Short answer
Describe what property caused the dyes to separate into different colors.
