    Chemistry Lab: Conservation Of Mass. PURPOSE: To determine experimentally whether mass is conserved in a particular set of chemical reactions. $

  • Christina Dorsey

    Matter cannot be created or destroyed by a chemical change. During a chemical change (reaction), the atoms of one or more substances (reactants) undergo some "rearrangements". The "rearrangements" can create "different" subtances, but the original atoms are still there. The total mass of the reactants before the reaction will be the same as the total mass of the products after the chemical reaction (in a closed system).

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.

Chemistry Lab: Types Of Chemical Reactions. The purpose of this lab is: 1) To observe some chemical reactions and identify reactants and products of those reactions. 2) To classify the reactions and write balanced equations. $

60 Chemical Reactions Task Cards - I normally avoid tpt, but this looks interesting.

FREE. Chemistry Lab: Heat Of Crystallization. Purpose: The student will determine the heat of crystallization of a wax sample.

Set up an organized chemistry review with stations covering topics such as chemical and physical changes, components of chemical equations (vocabulary review), modeling formulas, recognizing balanced and unbalanced equations, modeling chemical equations, fill-in-the-blanks atomic structure vocabulary, atomic structure table (with element name, symbol, atomic mass, atomic number, protons, neutrons, electrons), building an atom model, and chemical reactions review task card questions.

Lab: Isotopes and Atomic Mass. Purpose: 1) Determine the average weights of each isotope of the fictitious element Vegium. 2) Determine the percent abundances of the isotopes of vegium 3) Calculate from experimental data the atomic mass of vegium ($)

This lab requires that you already have density cube sets, you that you have various cubes made of different materials that the students can measure etc. This lab was designed for block sets where the blocks all have the same volume, but varying masses and densities. This is great because it helps the students understand that density does not rely only on size, that when the masses change within the same volume, the density changes as well.

Matter and Change 4 Mini Labs (Elements, compounds, mixtures, density). Nothing gets kids more excited about science than doing science experiments. This set of 4 mini-labs includes experiments that are fun, engaging, and thought provoking. These experiments will reinforce the concepts you have taught in class as well as develop good critical thinking and problem solving skills.

Density Lab PURPOSE 1) To practice the techniques used to determine mass and volume 2) To learn to calculate the density of a variety of objects.

Chemical Reactions Lab! Perfect for teaching chemical change! Includes a a PowerPoint for the lab write-up, lab data/question page, chemical/physical property and change foldable, and evidence of change tabs.

Photosynthesis with M&M's. After learning the photosynthetic equations students put their knowledge to work building the molecules in the equation out of M&M's. Students are also reminded of the Law Conservations of Mass. Link to lesson provided.
