Teaching Tips

Educator should work through the interactive thoroughly before students start.

There are two options on the interactive lab bench section that asks if students want to use the signals that indicate is a correct lab technique choice has been made. It is strongly suggested that students use this.

Based on length of classroom time, educator may need to break up the virtual lab experience into two class periods, completing part one in the first class and part two in the second class.

Students should share their data on the board and create a class data table and graph, which could also include data from other classes doing the same activity.

VirtualUrchin website has several interactives that students can explore prior to doing the ocean acidification lab.
