what are the 2 components they test the bridge on?
mass & weight-bearing
would cling wrap or foil be a better idea for the windows
cling wrap
what is the best shape for the wind turbine's blade?
triangle
how do you win this game?
gamble
which bridge structure is the best option for the challenge?
truss (triangles one)
why is it a bad idea to cover the roof using cardboard?
not waterproof & less sturdy
why is balance really important when making the wind turbine? (balance meaning placement of blades, weight of blades, etc)
- wastes energy, causing fan to go slower
- makes the forces spread out unevenly, meaning more chance of damage
how many tries do you get for each scenario testing?
1
what do you have to measure before designing?
the height of the bridge platform
water catchment, weight bearing, wind strength
how many blades is ideal for the turbine?
3 to 4
a scenario that tells you to collect only HALF of the 'fish' (marbles), what do you do?
create a vertical border/ pocket on one half of the board, to collect half of the marbles and let the other half flow through
is mass or weight bearing more important?
trick question, neither
why shouldn't you use all the materials to make your house in order to pass the tests?
more materials = more money
why shouldn't you start recording the amount of spins as soon as the turbine starts spinning?
the turbine hasn't reached its max. speed yet - loosing points
what is the most important thing to remember in this challenge?
TIME MANAGEMENT
why are triangle supports better than rectangler supports?
- keep their shape under pressure
- absorb/ transfers the forces using tension and compression (explain)
choose the best option:
flat roof, triangular prism roof, half sphere roof, cone
triangular prism
what shape is the tail?
trapezium
what is another important thing to think about during this challenge?
do not overthink
