More on Equilibrium: a suggestion to have students draw representations of the system before and after the stress is applied. A teeter totter is an often used analogy.

The lesson plan developed by the 11/6/12 DAIT group a concept map to go with the unit Note: during the lesson study we found that some teachers spend considerable time on learning the reaction types and activity series, neither of which is tested on the CST or reflected in the released test questions.

A lab from Pam on comparing the activity of different metals

Students can verify conservation of mass by comparing the mass before and after a simple reaction that releases gas (i.e. Alka Seltzer and water) and then be challenged to find a method of trapping gas to verify that no mass is lost given an assortment of materials. Some people can get balloons to work, but I have had success with 22 oz soda bottles.

quick labs or demos to mass before and after- Iron wool over a flame, candle while it burns,


A chemical formula worksheet

A reading on Avogadro's number.

A great tool that can be adapted for any test (Choose to do this with a few key items)

A lab comparing ionic and covalent compound in terms of conductivity

This lab gives hands-on experience with the mole concept

Have students weigh out a mole of different elements and compounds (charcoal for carbon, copper shot, water, zinc pellets, iron filings)- give them the amount to weigh out and try to figure out what they all have in common.

Pam Ls way of teaching Stoich problem solving

A yummy way to learn Stoich

A game to practice balancing equations-

Pam L. uses a laminated card stock with circles on it instead of spot plates to do dropper bottle reactions.

For ionic bonding do modeling activities where students are assigned an element and some need to give away chips and some need to gain chips (eg. boys are metals and girls are non-metals). You can run this like musical chairs where students have a short time to find a partner and sit- use the music from the dating game.

Students guess how many water molecules are released from a single exploding popcorn kernel. Then have them pop 20 popcorns in a beaker covered with foil with holes in it. (pop it the old fashioned way with a little oil and shaking the beaker on a hot plate). Based on the change in mass, they should be able to calculate the number of water molecules that escape from one kernel.

Use ball and stick models to build models of reactants, then re-arrange them to form products. Start with the methane burning reaction and demonstrate how gas burns dirty without enough oxygen by holding a white plate over restricted burner. When there is enough oxygen (balanced rection) the gas will burn clean and will not leave residue on the plate.
