The Nano Scale
Starters
• How tall do you think you are in inches and meters?
• Record your estimated height.
• Use the meter sticks to take your height and compare it to your estimation.
• List 5 objects that have a similar height (only one may be another classmate).
What is the average height in meters of a middle schooler?
• Take your colored dot and place on the histogram at your height.
• So, what is the average?
• Insert histogram.
Can you name an object that is 2 times bigger than our class average?
Can you name an object that is 10 times bigger than our class average?
