This is a great lab to begin with in your scientific method unit! Students will test whether or not the 5 second rule is really valid or not. Three versions of this lab are included: 1. Teacher led (grades 6-8)- Students will be given the procedures for the lab and be expected to test the experiment, collect data, and draw conclusions. 2. Student led (grades 9-12)- This inquiry based version allows students to come up with their own experimental design. Many students will not have the best set-up, and that is okay! It leads to great discussion about controlled experiments. Both versions have been left editable so you can change food types, amount of time food is dropped, etc. 3. Student led (grades 9-12)- Same format as the inquiry based version but includes a CER chart instead of post-lab questions. To complete this lab you will need to order pre-poured agar plates from a biology supply company or pour your own. Other materials you will need: food source, gloves, stopwatches, stereoscopes (optional).
