WHO’S GOT THE HOTTEST WHEELS?
a scientific method lab
INSTRUCTIONS: Work with your group to design and test an experiment with three different types of
Hotwheels cars. Make sure you fill in ALL of the blanks below.
QUESTION:
Which type of matchbox cars will go the farthest?
VARIABLES:
Distance cars go
Type of car
Person rolling car
Area car is rolled in
Times cars are rolled
INDEPENDENT VARIABLE: ____________
DEPENDENT VARIABLE: _____________
CONSTANTS: ____________________________________
HYPOTHESIS: If I roll all three types of cars, I think the __________ car will go the farthest
because _________________________________________________________
EXPERIMENTAL DESIGN: Answer the questions below about how you want to conduct your experiment
with your group.
1.
How many times do you want to roll each car?
2.
(FROM QUESTION 1) If you chose MORE THAN 1 time, how will you decide which time will count
towards results?
3.
How many people will roll the cars?
4.
How will you measure how far each of the cars roll? 5. How will you show your data? Table?
Graph? Both?
MATERIALS:
• 3 types of matchbox cars
• ruler or something to measure distance
• space large enough to roll the cars
PROCEDURE: Write detailed steps you will follow to figure out which car rolls the fastest (make sure to
make it SO DETAILED that if someone wanted to replicate it, THEY COULD!). ** INCLUDE:
measurement and times 1.
