Chromatography and other chemistry techniques

Students started with a safety cartoon where they needed to identify what the people in the drawing were doing correctly and incorrectly. It was a contest and the winner had more than 50 points!

Next we discussed chromatography. Chromatography is used to separate inks into the colors that make them up. The reason it works is because the colors of ink have different size particles. The small particles move faster and will move further up the paper strip. Some black inks are actually made up of blue red, pink, and yellow.

We also discussed quantitative and qualitative observations. Qualitative observations are qualities and can be observed with the senses. Quantitative observations include numbers and are usually measuring something about an object. Toys were passed out for the students to practice with.
