Engineering a Raft for Juniper

The video introduces a problem-solving scenario where the characters need to build a raft for Juniper. They approach the problem like engineers, discussing and selecting materials that float, such as craft sticks, corks, cardboard, and aluminum foil. Various designs are proposed, each addressing specific needs like size, safety, and buoyancy. The video emphasizes collaboration and testing to find the best solution, encouraging viewers to think like engineers.

Why does Juniper need a raft?

• Because she is afraid of water.

• Because she wants to build a sandcastle.

• Because she wants to swim.

• Because Squeaks' toy boat is missing.

What is one of the first steps engineers take when solving a problem?

• They immediately start building.

• They talk and share ideas.

• They ignore the problem.

• They buy new materials.

Which material was found to float and could be used for the raft?

• Modeling clay

• Big flat rock

• Craft sticks

• Paper

What was a key feature of Juniper's raft design?

• It was made of cardboard.

• It had a sail.

• It was made of aluminum foil.

• It had a motor.

What was a concern with Dino's paper airplane design?

• It was too small.

• It was too expensive.

• It was too heavy.

• It might get soggy and sink.

What was a unique feature of Squeaks's raft design?

• It was powered by a fan.

• It had a handle for safety.

• It was made of aluminum foil.

• It had a sail.

What did Sam's raft design include to help it float?

• A motor

• A large rock

• A paper sail

• Corks on the bottom

What was the main purpose of testing the different raft designs?

• To see which one looks the best.

• To determine which one solves the problem best.

• To find the most expensive design.

• To see which one is the fastest.

What is the next step after designing the rafts?

• Building and testing them

• Painting them

• Throwing them away

• Selling them

What is the main goal of the raft designs?

• To be the fastest
