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).

Construct a scientific explanation based on evidence for how environmental and genetic factors influence the growth of organisms. Examples of local environmental conditions could include availability of food, light, space, and water. Examples of genetic factors could include large breed cattle and species of grass affecting growth of organisms. Examples of evidence could include drought decreasing plant growth, fertilizer increasing plant growth, different varieties of plant seeds growing at different rates in different conditions, and fish growing larger in large ponds than they do in small ponds. Assessment does not include genetic mechanisms, gene regulation, or biochemical processes.
