Exploring Experimental Design with Toy Cars and Ramps

The video tutorial explains how to conduct a simple experimental investigation using toy cars and ramps. The teacher emphasizes changing one variable, measuring another, and keeping all else constant. The investigation focuses on how the height of a ramp affects the distance a car rolls. Students are encouraged to discuss the investigation's question and later, the teacher concludes by explaining the relationship between the ramp height and the car's rolling distance.

What is the first step in performing a simple experimental investigation?

• Measure multiple variables

• Keep all variables the same

• Change one variable

• Change multiple variables

What was used in the investigation to measure the distance the cars rolled?

• A meter stick

• A scale

• A ruler

• A stopwatch

What was the variable that was changed in the investigation?

• The height of the ramp

• The length of the ramp

• The surface of the track

• The type of car

What was kept constant during the investigation?

• The time of day

• The type of cars and tracks

• The distance measured

• The height of the ramp

What tool was used to measure the distance in the investigation?

• A ruler

• A meter stick

• A tape measure

• A laser distance meter

Why is it important to keep everything else constant in an experiment?

• To ensure the results are accurate

• To make the experiment easier

• To use fewer resources

• To save time

What question was the investigation designed to answer?

• How does the length of the ramp affect the speed of the car?

• How does the height of the ramp affect the distance rolled?

• How does the surface of the track affect the distance rolled?

• How does the type of car affect the distance rolled?

What was the main focus of the investigation?

• The distance the cars rolled

• The material of the ramp

• The speed of the cars

• The type of cars used
