Semester 1 Test Review

Ethan, Jackson, and Daniel are conducting an experiment in their physics class. Which of the following hypotheses is written correctly for their experiment?

• Frozen tennis balls will not bounce as high.

• If Ethan freezes a tennis ball, then it will not bounce as high.

• If Jackson freezes a tennis ball, it won't bounce as high as one that Daniel has not frozen.

• If Daniel heats up a tennis ball, it will bounce high.

Olivia, James, and Daniel are working on a school project. They need to follow a series of steps designed to help them solve problems and answer questions. What is this process called?

• Hypothesis

• Experiment

• Scientific Method

• Observation

Maya and Michael are conducting a science experiment. In their experiment, the variable that Michael decides to change is called what?

• Controlled variable

• Experimental variable

• Dependent variable

• Independent variable

Ethan is trying to understand the concept of linear equations in his math class. Samuel explains to him that there is a standard form to represent these equations. Can you help Ethan identify the correct slope-intercept form that Samuel is referring to?

• y=mx+b

• y=x+b

• mx+y=b

Grace, Isla, and Aria are studying for a math test. They come across a problem where they have to write the slope-intercept form of a hill's incline. The hill has a slope of -2/5 and the y-intercept is -2. What is the slope-intercept form of this hill's incline?

• y = -2/5x - 2

• -2/5y = x - 2

• 2x - 2/5y = 0

Arjun is trying to calculate the slope of a hill. He came up with the formula 6x - 3y = 12. Which is the correct way for Arjun to write this formula in slope-intercept form?

• -3y = -6x + 12

• y = 2x - 4

• y = 2x - 13

Isla, Elijah, and Samuel are trying to build a ramp for their skateboard park. They want the ramp to have a specific slope and intercept. Which of the following equations represents the slope-intercept formula of the ramp they are planning to build?

• -4x + 3y = 2

• 3y = -4x + 3

• y = -4/3x + 3

William is studying the growth of a particular plant species. He has collected data for 6 months but wants to predict the growth for the next 2 months. What should he do to extend the graph, along the same slope, above the measured data?

• Interpolate

• Extrapolate

• Dependent

When James increases the speed of his car, the distance covered by the car also increases.

• Directly Proportional

• Inversely Proportional

• Control

William is conducting a science experiment and needs to measure the mass of a fly he found in his garden. Which unit should he use?

• grams

• liters

• meters

• celsius
