on agriculture, land use and human nutrition. Most of you have already seen Food, Inc. in SuperScience. We will discuss parts of that video as we go through this unit.
Prior to beginning Science Fair presentations, I had you make lists of household cleaners. Most of your have developed a lab testing some of those cleaners/chemicals on wheat grass (wheat seeds that have been planted and germinated). Some of you have thought you may want to see what the wheat grass looks like when the chemicals are applied directly to the grass; others want to test soil pH; still others see what the lethal dose is going to be.
We will start this experiment this week and see where it takes us. We will need to conclude the experiment before break so that you can turn in a formal lab report.
