A _________________________is study of motion.

• a. Kinematics
• b. Alegbra
• c. Time
• d. Force

As illustrated in the STEM challenge activity, the ball run uses different forms of energy, and these are _______ and ________?

• a. potential energy to kinetic energy
• b. kinetic energy to potential energy
• c. gravitational potential energy to kinetic energy
• d. all of the above

When the ball collides or bounces off something, some of the kinetic energy is converted to other forms, like sound. Sound is known as _________ energy.

• a. Potential energy
• b. Acoustic energy
• c. Thermal Energy
• d. Kinetic energy

As the ball moves, some of the energy is lost to friction and converted to heat which is also known as __________.

• a. Potential energy
• b. Chemical energy
• c. Thermal Energy
• d. Kinetic energy

The ball run might make use of different simple machines, which below are samples of simple machines?

• a. Levers
• b. Inclined planes (ramps)
• c. Wheel and axle
• d. All the above

"To design and build a ball run for a ping pong ball using nothing but paper and tape. Their goal is to make the slowest ball run possible". This statement is an example of what STEM step or process?

• a. Ask
• b. Imagine
• c. Test
• d. Plan

If a student makes a ball run taller, it can take longer for the ball to travel through it. However, building a taller ball run can be difficult. It needs to be sturdy, so it does not fall over. For example, students might need to connect beams in triangular shapes to form _____________ to support a tall ball run.

• a. Bridge
• b. Truss
• c. Cable
• d. Tension

In the engineering design process, students will need to design, build, and test their ball runs, and then change them or make improvements, and test again. This process is called _____________.

• a. experiment
• b. repetition
• c. alteration
• d. iteration

In this STEM challenge, your goal is to make the ping pong ball run longer or to go down slower, thus you need to measure _________. It is known as the measured or measurable period during which an action, process, or condition exists or continues.

• a. Time
• b. Distance
• c. Force
• d. Velocity

What options or features to add to the marble run to make the ping pong ball go down slowly?

• a. Make the run taller or longer
• b. Make the run a little less inclined
• c. Add obstacles or features
• d. All of the above
