Reflection: Adjustments to Practice Company Erosion Solutions - Section 5: Testing Solutions


The kiddos were extremely excited to try out their erosion solution and absolutely involved in the lab, but when it came time to write the observations, it was like letting air squeak out of a balloon. I felt like I said 'write your observations' or 'who is the geologist /hydrologist ... they need to write the observations' with every other sentence that came out of my mouth.

Isn't there a saying that goes something like 'best laid plans...? I had plans, I thought by designating who would write the observations and sharing the task among 3 students there would be this synergy to ... write observations.

I don't know maybe it isn't as bad as all that. The kiddos were involved and I have not seen the the team's lab papers since the mud has dried, but those observations sure looked scanty when water was eroding the hill.

Since students tested only one of their two designs, I had an opportunity to modify how I presented the jobs. The student job descriptions were on one page. This made it less user friendly for students to access the tasks they were to do for their job.

For the second day of the lab,  I had each job on its own half page and stapled to the lab papers that go with that job. To encourage everyone to help with the observations, I stressed that all company members should help with the observations.

For the 2nd day, I encouraged the kiddos to discuss their job responsibilities, instead of me discussing it. They need time to read the job descriptions and digest what this will look like in their lab.

That first day, I knew we had only so much time to do the lab, but in the long run, laying a solid foundation so that the students understand their roles in running the lab would most likely save time. Its all in the prep.
