I handed out The Simpsons worksheet over the scientific method and we worked through the first problem together identifying the difference between Independent Variables and Dependent Variables and reminded students tat they should only manipulate or change one variable at a time to have a valid scientific experiment or observation. We also spoke about Control Variables and the difference between this and Control Groups. Students were then permitted to work on the sheet with a partner. Anything not completed was assigned as homework and will be collected today.
I did ask every class to calculate the percent difference between the experimental group and control group in Smithers experiment as part of the homework. A tutorial on calculating percent difference can be found on that link.
Add Step 5 to the scientific method concept map. Begin graphing in Excel
