100

What is the first step of the Engineering Design Process?

Ask (what’s the problem?)

100

What simple machine is a catapult based on?

A lever

100

What block starts many Scratch programs?

When green flag clicked

100

What do you need for a circuit to work?

A complete loop

100

What sensor helps Milo know if something is in front of him?

The motion (distance) sensor.

200

What step do you create drawings or plans in?

Imagine/Plan

200

Pulling back a catapult stores what kind of energy?

Potential energy

200

What does the “forever” block do?

Repeats code again and again.

200

What provides power in Snap Circuits?

The battery pack

200

What does the motor help Milo do?

Move or spin parts of his body.

300

What does “prototype” mean?

A first model you build to test your idea.

300

What force helps slow things down when they rub together?

Friction

300

What is a sprite in Scratch?

A character or object you can code.

300

What does a switch do?

Turns the circuit on or off.

300

What does the WeDo Smarthub need to connect to a tablet or computer?

Bluetooth

400

Why do engineers test their projects?

To see what works and what needs to change.

400

In the fan build, why should the fan blades be even on both sides?

So it spins smoothly and doesn’t wobble.

400

What kind of block makes your sprite ask questions or talk?

A “looks” block (like “say ___”).

400

If a fan won’t spin, what should you check first?

If any pieces are loose or not snapped in all the way.

400

If Milo isn’t moving, what’s the first thing you should check?

If the Smarthub is turned on and connected.

500

Why is the “Improve” step important?

Because no design is perfect the first time. Improving makes it stronger and better.

500

Why do engineers test a catapult many times?

To find the best angle, power, and design to make it launch farther or more accurately.

500

What is a variable used for in Scratch?

To keep track of things like score, time, or lives.

500

Why do some circuits make lights dim or fans slow down?

Because electricity has to go through more parts, which slows it down.

500

Why is it important to test Milo after you build him?

To make sure the pieces are connected correctly and the code works.
