The flower is not necessary) The Challenge: Calculate how many revolutions the bee will make, given its programmed speed and time. Procedure: 1. At a speed of 1, the bee makes about 0.6 revolutions during the first second of the program and 0.45 revolutions for every second thereafter. About how many revolutions should the bee make during 7 seconds at a speed of 1?______
Determine the relationship between the number of blue handle turns and the number of green handle turns. Procedure: 1. How many teeth are on the gear turned directly by the blue handle? _____ 2. How many teeth are on the gear connected to the gear turned directly by the blue handle? _____ 3. How many times bigger is the gear turned directly by blue handle compared to its connecting gear? (divide answer #1 by answer #2) _____ 4. How many teeth are on the gear on the other end of the axle from the gear in answer #2? _____ 5. How many teeth are on the gear turned directly by the green handle? _____ 6. How many times bigger is the gear in answer #4 compared to the gear turned directly by the green handle (divide answer #4 by answer #5) _____ 7. To find the number of times green handle turns for each blue handle turn, find the product of the two relationships between the pairs of connecting gears. (multiply answer #3 times answer #6) _____. 8. Turn the blue handle completely around once. Does the green handle turns completely around this many (answer to #7) times?______ If not, check your work for steps 1-7. 9. Now complete the chart below. To find “Green Handle Turns,” multiply “Blue Handle Turns” by answer #7. You can then check your answers by turning the blue handle and counting the turns of the green handle. Blue Handle Turns Green Handle Turns
2. Gear A drives Gear B. How many times more teeth does Gear A have compared to Gear B? (divide the number of teeth on Gear A by the number on Gear B) ____ 3. Gear C drives Gear D. How many times more teeth does Gear C have compared to Gear D? (divide the number of teeth on Gear C by the number on Gear D) ____ 4. Gear E drives Gear F. How many times more teeth does Gear E have compared to Gear F? (divide the number of teeth on Gear E by the number on Gear F) ____ 5. To find the number of times green handle turns for each blue handle turn, find the product of the three relationships between the pairs of connecting gears. (multiply answer #2 times answer #3 times answer #4) _____. 6. Turn the blue handle completely around once. Does the green handle turns completely around this many (answer to #5) times?______ If not, check your work for steps 1-5. 7. Now complete the chart below. To find “Green Handle Turns,” multiply “Blue Handle Turns” by answer #5. You can then check your answers by turning the blue handle and counting the turns of the green handle.
