Encourage them to try more than once, to ensure that their observations are correct. Have students observe the starting point of both the handle and the minifigure. If you want Sam or Sally to make a full turn, how many times must you crank the handle? For the prediction, the correct answer is model A7 however, it does not matter whether students get the answer right or wrong at this point, only that they should make a prediction that can be checked later. If I compare model A6 to model A7, then I think Merry-Go-Round Model (A6/A7) will turn faster.Įncourage students to discuss the effects the different gearing has on the merry-go- rounds in their own words. Next, look carefully at the pictures of the models and make a prediction. Students should notice the difference in both size and number of gears used on model A6 compared to model A7.Ĥ. What do you notice? Explain how the models are different. Then look carefully at the pictures of the models and compare Merry-Go-Round Model A6 to Merry-Go-Round Model A7. He has been a Lego maniac since kindergarten.There are two gears used in model A6: a spur gear (8 teeth) and a crown gear (24 teeth).ģ.

This phonograph is by no means high-fidelity but provides the tool to play records from the $2 bin or other vinyl you do not mind damaging as you experiment with building Lego and programming in Scratch. You, of course, might already have all the bricks needed to build the phonograph and can purchase the Lego M-Motor and Lego USB Hub separately. The motor speed is programmed in Scratch, which interacts with the phonograph through a USB hub. This particular phonograph is build from the programmable Lego WeDo Kit. Based on an arm design by Jose Pino and using a Lego WeDo motor and the Scratch programming environment, my friends and I built a phonograph that played a record loudly enough to be heard across the room with no amplifier needed: just a nine ounce plastic drinking cup serving as the horn! I have built a series of Lego phonographs, but none as successful as this model. Gift the gift of Make: Magazine this holiday season!
