Here is a lesson on chemical changes and reactions that already incorporates many 21st Century Skills, including critical thinking and collaboration. To extend the 21st Century Skills, teachers may also discuss with their students the surprising effect of mixing chemicals and how this relates to the harmful nature of chemicals we use in everyday life (e.g. household cleaners, gasoline, antifreeze). Have the students discuss the need for responsible handling of chemicals for both health reasons and environmental reasons. In groups, have the students work together on the computer to research and collect images on the use, on the dangers, on proper storage, and on the disposal of household chemicals. After performing their group research, have the students use this information to develop a multimedia presentation explaining the virtues and dangers of chemicals in the house and the responsibility of people in society to handle them carefully.
Students will be able to observe changes and design experiments to explain observations.
Students will demonstrate critical thinking by actively participating in discussion and research on household chemicals. Students will demonstrate ICT Literacy by locating images and information about a household chemical on the internet. Students will demonstrate collaboration skills by working within student groups.
