Bitesize, animated videos covering many chemical reactions topics, organised into these chapters: rates of reactions, equilibrium, redox, electrolysis and energetics through engaging, bitesize animated videos.

The aim of this lesson is to introduce the concepts of Electrochemistry and Electroplating and to present their applications in our daily lives. Students are encouraged to construct their knowledge of Electroplating through brainstorming sessions, experiments and discussions. This video lesson presents a series of stories related to Electroplating and begins with a story about house gates as an example of the common items related to the Electroplating topic. Prerequisites for this lesson are knowledge of the basic concepts of electrolysis and chemical equations. The lesson will take about 60 minutes to complete, but you may want to divide the lesson into two classes if the activities require more time.

This video resource is presented as a real-world application of chemistry in the field of archaeology. Conservator, Nichole Doub, walks through the process of electrolytic reduction and how it is used to conserve archaeologically recovered artifacts. Use to support Maryland/NGSS for grades 5, MS, and HS. For 5-PS1-1, pair with the Exploratorium's "Copper Caper" activity for a similar reaction which can be conducted safely in the classroom--have students watch the video and discuss why the spoon formed tarnish and why the tarnish was not visible as particles moved from the spoon to the sacrificial anode. For MS-PS1-1, pair with the Exploratorium's "Indicating Electrolysis" activity and have the students explain the charges of oxygen/hydrogen and compare/contrast those with the silver and sulfur in the tarnish. Have students research silver sulfide (the usual tarnish found on silver artifacts) and model a single molecule of it before and after electrolysis. For HS-PS1-1 have students research silver sulfide and model a molecule of it prior to watching the video and predict what will happen when the positive or negative charges change. For HS-PS2-6, have students postulate why, historically, coins were made from silver and gold (with reference to their chemical reactions), then have students design a coin and specify a different metal to make it out of, explaining why the atomic properties of that metal make it appropriate for use in currency.

Students act as engineers to apply what they know about how circuits work in electrical/motorized devices to design their own battery-operated model motor vehicles with specific paramaters. They calculate the work done by the vehicles and the power produced by their motor systems.

Through this lab, students are introduced to energy sciences as they explore redox reactions and how hydrogen fuel cells turn the energy released when hydrogen and oxygen are combined into electrical energy that can be read on a standard multimeter. They learn about the energy stored in bonds and how, by controlling the reaction, this energy can be turned into more or less useful forms.
