Criteria
Criteria
Work in family teams.
Complete design and construction of the merry-go-round within allotted time limit.
Brainstorm and sketch the design of the LEGO® merry-go-round in your journal and show plans to your FT&T facilitator before beginning construction.
Build a merry-go-round from the LEGO® set, powered by a motor.
The LEGO® merry-go-round should carry two to four LEGO® people and go slowly so the LEGO® people do not fall off.
Demonstrate and explain your merry-go-round design to other family teams during the Wrap-Up.
Write your reflections about the activity in your journal, using the FT&T Journal Page as a guide.
Gear ideas
Gear ideas
To slow the speed of your merry-go-round, use a small gear or pulley to turn a larger gear (A) or pulley (B). The more times this gear or pulley sequence is repeated (small to large), the further it will slow down the speed.
A
B
Changing the direction of movement can be accomplished using the worm gear (C) or the crown gear in different combinations. To stop an axle from wobbling, place a thin plate with holes over it (D).
