There are many free versions of this lab on the internet, but I've found that many of those labs are not as complete or clear, especially in the directions and background information areas.
This version of the lab includes specific, easy to follow directions for students, as well as a great review of the scientific method, experimental design, variables, and graphing. It also introduces students to conclusion writing in a way that would be a great first scaffolding step to start students towards writing detailed conclusions.
Students can do this lab over the course of 4 days (about half a class period for days 1-3, and all day on day 4). It's a great opportunity to allow for some remediation on the other types of transport either before or after they complete their lab portions for the day.
This product includes:
*Teacher recommendations for lab prep and administration
*Student lab packet (includes scoring break down in the details section of each slide for easy grading) **EDITABLE BY PURCHASER**
*Lab sample/answer key
Please feel free to ask questions if you'd like to know more! Thanks for looking!
