Conservation of matter lab- This is an important concept in chemistry: In a chemical reaction, all the atoms in the reactants end up in the products. When an equation of a chemical reaction is written, it is “balanced” to show this. A balanced chemical equation shows that no atoms are destroyed and no new atoms are created in the chemical reaction. Explain to students that another way of saying that no atoms are created or destroyed in a chemical reaction is that mass is conserved.

PURPOSE: To compare the experimental mass to the theoretical mass of a product of a chemical reaction. Given the mole relationships in a balanced chemical equation, and the mass of one of the reactants, it is possible to determine the number of moles of every other substance taking part in the reaction.

Here's a set of lab safety dominoes and related posters.

This is a nice little demonstration showing the Conservation of Mass in action. Educational Videos for all levels of chemistry. The video could be used in the classroom by teachers or viewed by parents/students to gain a better understanding of conservation of matter.

This lab is a classic! Students will be working in small groups to watch a chemical reaction occur before their excited eyes! The lab starts with preliminary questions that get them thinking about Magnesium. After they burn the Magnesium (the burning of the Magnesium does not take long at all) they will answer a few analysis questions regarding the reaction they just witnessed. This lab is always a total HIT with my 8th graders, although this would be fun in any chemistry class.

This is a set of 4 mini-labs that I use when teaching my unit on Matter and Change. Each mini-lab is a stand-alone activity, so you can choose to do all of them or just a few of them. Purpose of the labs: 1. To determine the density of pennies minted before 1982 and after 1982. 2. To use paper chromatography as a method of separating the components of a mixture. 3. To determine if a strange substance is a solid or a liquid. 4. To observe several chemical changes.

Chemistry Lab: Specific Heat Of A Metal. PURPOSE: To calculate the specific heat of a metal using mass and temperature data obtained by using a calorimeter. $
