Answer: hypothesized that the higher pH levels would increase the rate

of movement of the Artemia. The students placed the Artemia in petri dishes with 2 mm x 2

mm grids marked off on the bottom of the dishes. The students calculated how fast the Artemia

traveled in each pH (4-9) solution by counting the number of squares on the grid that the

Artemia crossed per second of timing.

The data collected from their experiment is presented below:

pH of Water

Rate of Movement of

Artemia

(squares per second)

1. Using the grid below, create a graph based on the above data.
