science on the week of halloween

this week in science, i was sick from the flu until thursday:

On thursday, i had no clue what was going on.

we talked about how an index works. this is the most simplified ratio when making a ratio on a quantitative observation.

We use index making when there is something moving per a time measure.

suppose a pop corn machine makes 10 corns in the period of 7 seconds. This is a ration of how it looks before simplification

10/7=?/1

so, we divide the ten by seven and get 1.428.

that was the rate of how many kernels were popped in one second. this is a simplified index.

This is important to us because we should be able to know how to calculate simplified ratios for different rates.
