Science - Chemistry
Standard 4 Objective 1
1 class periods of 90 minutes each
Students will perform chemical reactions for the class to observe evidence of reactions and write equations to describe the reaction.
Each student will need a copy of the student sheet attached. Each section has the chemicals listed that will be needed for each group.
1-84 min class period. About 15 minutes for an introduction and separating into groups (this can be done the previous class period). Then, about 25 minutes for students to prepare their reaction and presentation and another 30 minutes for each group to present and cleanup.
Students should where goggles and work in the fume hood. Most of the chemicals can be discarded either in the garbage (solids) or down the drain with water (liquids). Be sure the acids and bases have been neutralized with baking soda (for the acid) or hydrochloric acid (for the base) before dumping them down the drain.
Students should have a basic understanding of lab technique and safety. Also, students should know how to write balanced equations.
I gave students 15 points for actually doing the activity and presentation. Students earned an additional 5 points if they covered all of the questions on the student sheet for their group in their presentation and an additional 5 points for a completed student sheet for all groups.
