Science Review

1. What do you do when you COLLECT DATA by OBSERVING?

• offer an explanation

• make a statement

• plan a way of finding answers to your questions

• use your senses to notice details

Jesse added drops of liquid soap to three jars of water and shook each jar. Then he measured the height of the bubbles in each jar. The graph below shows the results.

Analyze the patterns in the data to construct a reasonable explanation based on the evidence from the investigation.

• The more soap a jar has, the more bubbles it will make.

• The more soap a jar has, the fewer bubbles it will make.

• The less soap a jar has, the more bubbles it will make.

• The amount of soap in the jars does not affect the amount of bubbles.

3. Why do scientists use models to represent the natural world?

• to investigate things that are too big or small to observe

• to measure the actual size of objects around them

• to compare data about different people

• to organize data into rows and columns

• one column for color, one column for length, and one row for each book

5. Which of these technologies can transport people the farthest distance in the shortest amount of time?

• an airplane

• bicycle

• a bus

• a skateboard

6. What is the main goal of the design process?

9. Kayla lives in a city with a lot of people. There is not enough land for each family to have its own house. How can engineers help solve this problem?

• by designing tall buildings where many families can live

• by communicating with others to share the problem

• by making a graph to show the number of people

• by telling different families that they must live together in one house
