Why do sidewalks in New Jersey have so many more cracks than the sidewalks in Florida?

• Only ice wedging is causing the sidewalk cracks in New Jersey. Both root wedging and ice wedging are causing the sidewalk cracks in Florida.

Do the cold New Jersey winters affect how many cracks appear in the sidewalk? To answer their question, Jayla and Aiden decide to carry out a science investigation. They first need to show that there are more sidewalk cracks in New Jersey compared to sidewalks in Florida. Which of the following could be used as evidence to answer their question? There may be more than 1 correct answer. Choose all the correct answers.

• They can use rulers to take measurements of the mushrooms that they notice along 3 streets in their neighborhoods. Then they can compare their measurements.

• They can take measurements of the cracks that they notice along 3 streets in their neighborhoods. Then they can compare their measurements.

• They can make observations and count how many sidewalk cracks they notice along 3 streets in their neighborhoods. Then they can compare their observations.

• They can make observations and count the number of houses they notice along 3 streets in their neighborhoods. Then they can compare their observations.

Do you think a volcano could pop up where Isabella lives in Peru?

• Yes, I think a volcano could pop up where Isabella lives. The map shows that there is already a volcano where she lives.

• No, I do not think a volcano could pop up where Isabella lives. The map shows that there isn’t a volcano where she lives so it could never happen.

• No, I do not think a volcano could pop up where Isabella lives. The pattern of volcanoes on the map shows that it’s not possible for a volcano to pop up in this location.

• Yes, I think a volcano could pop up where Isabella lives. The pattern of volcanoes shows that it’s possible for a volcano to pop up in this location.

Kenji finds some interesting black rocks next to a hill. The hill is very close to where Kenji lives. Kenji shows the rocks to a scientist, who tells him that the rocks are basalt. Basalt is a type of rock that is formed after lava erupts from volcanoes, but there currently aren’t any volcanoes where Kenji lives. Do you think that there used to be a volcano where Kenji lives?

• Yes, because the presence of basalt rocks indicates past volcanic activity.

• No, because basalt can also be transported by rivers.

• No, because the scientist mentioned there are no volcanoes.

• Yes, because there are many hills which could hide ancient volcanoes.

What would be additional evidence that Kenji could use to support a claim that there used to be a volcano where he lives?

• If Kenji finds more hills, but without basalt rocks near them in his neighborhood, this is more evidence to support his claim.

• If Kenji finds more hills with basalt rocks near them in his neighborhood, this is more evidence to support his claim.

• If Kenji finds other types of rock where he lives, this is more evidence to support his claim.

• If Kenji finds more basalt rocks where he lives, this is more evidence to support his claim.
