Building a Basic Solar Car

This video tutorial by Ben Finney from Science Buddies demonstrates how to build a basic solar car for the Junior Solar Sprint competition using the Jr. Solar Sprint Deluxe Kit. The video covers assembling the motor, attaching alligator clips, constructing axles and wheels, building the chassis, and mounting the motor. It also explains how to attach the solar panel and make necessary adjustments for optimal performance. The tutorial provides practical tips and highlights the importance of gear alignment and friction reduction for a functional solar car.

What is the primary purpose of the Junior Solar Sprint competition?

• To build the fastest electric car

• To construct a water-powered car

• To create a solar-powered car

• To design a wind-powered vehicle

Which tool is NOT required for assembling the motor?

• Flat-head screwdriver

• Needle nose pliers

• Hammer

• Phillips head screwdriver

What is the purpose of crimping alligator clips onto the motor wires?

• To solder the wires

• To attach the motor to the chassis

• To create a friction-based connection

• To connect the motor to the solar panel

What material is suggested for use as a bearing in the axle assembly?

• Rubber tires

• Drinking straws

• Plastic wheels

• Metal rods

Why is it important to ensure axles are parallel when constructing the chassis?

• To increase the car's speed

• To ensure the car rolls smoothly

• To reduce the car's weight

• To make the car look symmetrical

What is a potential benefit of making the solar panel adjustable?

• It reduces the car's weight

• It allows for maximum solar power absorption

• It makes the car more aerodynamic

• It simplifies the car's design

What should you do if the motor does not spin when connected to the solar panel?

• Replace the motor

• Check the alligator clip connections

• Increase the size of the solar panel

• Add more gears

What is the role of the gear on the motor shaft?

• To support the solar panel

• To mesh with the axle gear and drive the car

• To increase the car's speed

• To balance the car

Why might you need to adjust the motor or axle alignment?

• To increase the car's weight

• To change the car's color

• To ensure the gears mesh properly

• To make the car quieter

What is a key consideration when entering a Junior Solar Sprint competition?

• The number of wheels

• The official competition rules

• The car's weight

• The car's color
