The Nano Scale

Starters 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). How tall do you think you are in inches and meters? Record your estimated height.

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?
