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

• potential energy to kinetic energy
• kinetic energy to potential energy
• gravitational potential energy to kinetic energy
• all of the above

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

• Potential energy
• Acoustic energy
• Thermal Energy
• Kinetic energy

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

• Potential energy
• Chemical energy
• Thermal Energy
• Kinetic energy

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

• levers
• inclined planes (ramps)
• wheel and axle
• reels

"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?

• Ask
• Imagine
• Test
• Plan

Building a taller paper ball run can be difficult. It needs to be sturdy, so it does not fall over. Consider to connect beams in triangular shapes to form _____________ to support a tall ball run.

• Bridge
• Truss
• Cable
• 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 _____________.

• experiment
• repetition
• alteration
• iteration

In this STEM challenge, your goal is to make the marble/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.

• Time
• Distance
• Force
• Velocity

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

• Make the run taller or longer
• Make the run a little less inclined
• Add obstacles or features
• Make the run a little less inclined and add some obstacles
