New Mexico Ag Inquiry Institute here are the ppts that we shared at our workshop. Good Luck and Teach Them Well!!
Loved these activities at the FAST symposium last year! What liquids do you use for the Tracking the Spread lab?
You can use anything with a pH indicator. So you could use a baking soda/ water solution, or put a little acid in the water and use phenolphthalein indicator. Just remember which one you actually infected. Easiest to always infect the same number. couple of new activities with this like the irrigation, and engine shuffle. Hope things are going good.
