Engineering a Raft for Juniper

What was the main reason for designing a raft for Juniper?

• Juniper wanted to race with Squeaks.

• Juniper needed a new toy.

• Juniper was too small to swim.

• Juniper wanted to explore the lake.

What material did Juniper use for her raft prototype?

• Aluminum foil

• Craft sticks

• Plastic

• Cardboard

What was a major issue with Squeaks' raft design?

• It sank immediately.

• It was too expensive to make.

• It was too heavy.

• It was too small.

Why did Sam's raft design fail after some time?

• It was too difficult to build.

• It was too light.

• It was too small.

• The cardboard got wet and fell apart.

What is an important part of the engineering process according to the video?

• Avoiding any mistakes.

• Testing and improving designs.

• Using only one design.

• Getting it right the first time.

What did Squeaks suggest to improve the raft design?

• Make the raft smaller.

• Add a motor to the raft.

• Use craft sticks instead of cardboard.

• Use more aluminum foil.

What feature was added to the new raft design for safety?

• A sail

• Sides to prevent falling off

• A parachute

• A motor

What was the outcome of the final raft test?

• It sank immediately.

• It was too small for Juniper.

• It was too heavy to move.

• It floated well and was safe.

What did the team realize at the end of the video?

• They needed to start over.

• The original boat was available all along.

• They should have used a different material.

• They forgot to test the raft.

What was the overall lesson from the raft-building activity?

• Only one person should work on a project.

• Never test your designs.

• Engineering is about learning and improving.

• Always use the first design.
