For the past couple of days we have been watching and describing what MythBusters have experimented on two videos. We learnt about the scientific method – test, guess, use certain equipment, if it works – good, if not change one thing at a time. – and whether these myths are real or fake.
Duct Tape Tires;
Problem:
Can you ride a bike with duct tape tires?
Hypothesis:
We think that duct tape tires will work.
Variables:
(dependent)
How smooth the ride was. They measured using mls of water lost from a cup.
(independent)
They changed the tires;
rims
duct tape tires
regular tires
the W,L,H of duct tape wheels
(control)
They didn’t change course, distance, bike or person.
Experiment: (equipment + steps)
They used;
duct tape,
bike,
wheels,
rims,
cones,
cameras,
cup with water,
helmet,
biker,
flags,
Steps;
set up course
make duct tape tires
get cup of water on bike
ride bike with different wheels
Observation:
The regular wheels worked best because they were smooth, and lost the least amount of water. The duct tape tires were 2nd best but weren’t too smooth they lost less water than just rims. The worst type of wheels were the rims because they were rough and spilt the most water.
Conclusion:
It did work but I wouldn’t use duct tape, because I have wheels.
Water Slide Into Paddling Pool;
Problem:
Can you slide 150ft off a water slide into a paddling pool?
Hypothesis:
You can’t travel that far and land in a paddling pool.
Variables:
(dependent)
Speed, distance, direction
(independent)
starting point on slide – speed, body position, person sliding
(control)
Angle of slide, length and angle off the ramp
Experiment:
Equipment;
Water slide – same Angle, weight, height as in video.
Soapy water
Person/people
Cameras, GPS
Floating ring
Steps;
Set up slide
Water and soap on slide
Slide from ½
Slide from ¾
Slide from top
Set up floating ring and tried again
Repeated with another person
Observation:
One person reached 15mph down the slide and got 4ft, and then the next went 30mph and got 72ft. The higher on the slide where you start the further in the water you land.
Conclusion:
You can slide down the slide into a pool, just not that far or in that small of a pool.
