USE THE DATA TO ANSWER THE FOLLOWING QUESTIONS:
1. The bluestripe snapper (ta'ape) is an introduced species that is not native to the Islands. What would be the probability of catching this fish compared to the native lavender tang (mai'i'i)?
2. The mean biomass of the whitebar surgeonfish (maikoiko) is much higher than the mean biomass of the saddle wrasse (hinälea lauwili). Which fish would you be more likely to catch when you go fishing? Why?
3. What would be the mean biomass for all of the species combined?

Slope Game
Zap the cockroaches by figuring out the equations of their straight paths! The goal is to keep moving up to the next level!!
If you have extra time, you can practice guessing the rule of linear functions.

Slope
Below is a graph that matches the equation shown.
Slope slider
Play around with adjusting the numbers and figure out how they effect the graph.
#1. When you change the number multiplied by x, how does that effect the graph?
What happens when it is negative?
What does the graph look like when it is zero?
#2. When you change the number added at the end of the equation, how does that effect the graph?
What happens when it is negative?
What does the graph look like when it is zero?

Walking Rates
Everyone open your book to page 18 and read the directions.
Instead of doing 2.2 A on your paper, you are going to complete the tables on the computer.
Open the folder on the desktop labeled "Walking Rates"
Find your period, and the spreadsheet for you (ex: if you are in period 6 and in the "first rotation" at the computer station.... you'd be Per6 rotation 1 Walking Rates.xls)
Walking Rates
Terry walks 1 meter per second.
Jade walks 2 meters per second.
Jerome walks 2.5 meters per second.
Complete the tables by typing in the data based off each person's walking rate.
Answer questions on page 18:
A) How does the walking rate affect the data in the table?
B) How does the walking rate affect the graphs?
C) For each student, write an equation that gives the relationship between the time and the distance walked. Let d represent the distance in meters and t represent the time in seconds.
When you are finished, do the problems on page 17.
