In this Activity, students examine a piece of newsprint and recycle the paper to make a new sheet of paper that can be compared to other types of paper. They then use this experience, and information from Internet sites, to create a paper work of art. The Activity could be used as a cross-curricular topic in an art class.
When the outside temperature drops below 0°F (-18°C), the conditions tempt this experiment!
Recent ChemEd X posts about Expo neon markers led Tom Kuntzleman to create a video showing how he uses these markers to teach fluorescence and chemiluminescence.
One of over 100 activities in the collection, JCE Classroom Activity #92 describes how to test for the presence of iodide in iodized salt using only water, iodized salt, 3% hydrogen peroxide, vinegar and liquid laundry starch. Watch the video for an added twist to the activity.
Halloween is a great time of year to do experiments with fluorescence. Check out the video in which we experiment with some fluorescent yarn.
Have you ever seen the soap boat experiment? Check out the video.
This is a series of experiments, PhET Interactive Simulation activities, and clicker questions to relate macroscopic and molecular representations of homogenenous solutions. Graphing skills are also used.
Looking for an easy, hands-on experiment to use in your classroom at the beginning of the school year? In the June, 2013 issue of the Journal of Chemical Education, Isao Ikemoto and Kouichi Saitou describe a simple experiment to demonstrate the electrolytic dissolution of copper ions from a copper electrode. This experiment can be conducted using only items that are easily obtained around the home or in grocery stores.
Some students of mine and I have published two papers in the Journal of Chemical Education that describe how stunt people use chemistry to safely set themselves ablaze while filming action movie scenes. The secret behind this stunt lies in the use of superabsorbent polymer (SAP) gels. To pull off this trick...
I’d like to report on one of the end-of-year research projects that two of my general chemistry students completed during class this year. If you’d like read more about these end-of year research projects in general, click here.
