4th Grade Science Review Checkpoint 1

We are testing the effects of gravity. To make this a fair test, what procedure would we have to add?

• Use different cars for each trial.

• Increase the ramp height after each trial.

• Change the surface of the ramp after each trail.

• Add more mass to the car after each trial.

Students gather the following materials to conduct an investigation: a block of wood, a spring scale and different types of surfaces. What question could the students be answering?

• How do different surfaces affect how far the block is pulled?

• How does a magnet affect the force used on a block?

• How can we use a spring scale?

• How does gravity affect how far the block is pused?

When Macadamia nuts are mixed with cookie dough, they create a mixture. If a 650 gram bag of nuts is added to the bowl, what would be the mass of the nuts after being added to the dough?

• The mass of the nuts would be 2650 grams because it adds the mass of the dough.

• The mass of the nuts would be 2000 grams because the nuts mix with the dough.

• The mass of the nuts would be 1350 grams because the nuts mix with the dough.

• The mass of the nuts would be 650 grams because when two substances are mixed together, matter is conserved and the mass stays the same.

Which TWO statement are correct observations made about the mixtures?

• Mixture 1 is a solution because the lemon juice spread out evenly in the water.

• Mixture 1 is NOT a solution because the lemon juice spread out evenly in the water.

• Mixture 2 is a solution because the substances maintain their physical properties.

• Mixture 2 is NOT a solution because the substances maintain their physical properites.
