Clean up the environment with a lesson that focuses on replacing hazardous cleaning supplies with green, environmentally-friendly products. Using a dirty patch of surface as a control area, kids clean other parts of various surfaces...

Students analyze the chemical equation for the reaction between vinegar and baking soda. They observe that the gas produced in the reaction is also part of the products of the written chemical equation.

Students will observe an exothermic reaction in this activity where they add calcium chloride to a baking soda solution. This increase in temperature is due to the chemical change that has occurred.

See what happens when you dip a popsicle made of vinegar into a plate of baking soda in this science experiment.
