1. Students have a box of ice pops to take to their soccer game to sell on a hot day. The students know they need a device to keep the ice pops from melting for 3 hours. They have a $15 budget. Which step of the engineering design process does this demonstrate

• Identify the problem

• Test and evaluate

• Redesign

• Develop possible solutions

We do not want our glider wings to produce lift.

• True

• False

The three forces acting upon a glider are:

• weight, height, width

• weight, width, slope

• weight, thrust, drag

• weight, drag, lift

What is lift?

• the force that pushes and object DOWN

• the force that pushes an object UP

• the force that pulls an object down

What is thrust?

• the force that comes from a power source, and move and object FORWARD

• the force that pulls an object DOWN

• the force that pushes and object UP

What is drag?

• a force that pushes and object UP

• a force (resistance) that slows an object down

• a force, from a power source, that moves an object forward

What is weight?

• the force of gravity the pulls an object DOWN

• the force that pushes an object UP

• the force that pushes and object FORWARD
