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:
