In this isotopes worksheet, students review mass number, molecular notation, electron attraction, and electron orbits. This worksheet has 5 matching and 5 short answer questions.

In this stoichiometry worksheet, learners review mole conversions, percent composition, empirical formulas and molecular formulas. This worksheet has 6 problems to solve.

In this stoichiometry worksheet, students practice calculating moles, molar mass, and percentage composition of given compounds. This worksheet has 55 problems to solve.

For this compounds worksheet, students determine the number of molecules in molar mass for given amounts of different compounds. This worksheet has 5 problems to solve.

Students experiment with inner tubes, weights, flasks, and pistons to demonstrate the gas laws. In this molecular motion lesson, students demonstrate pressure as a force per area. They conduct an experiment to show the relationship...

Students convert Celsius to Kelvin temperature. Students conduct three lab experiments, gas law simulations using Internet applets, lectures and demonstrations. The Laws included are Boyle's, Charles, Combined Gas, Ideal Gas, and Gram's...

For this empirical formulas worksheet, students read about determining empirical formulas from chemical formulas. They determine the empirical formula given ten molecular formulas. They also find the molecular formulas given the mass and...

Students experiment to examine high and low pressure areas. They investigate why a high pressure area seeks a low pressure area.

The radical reactions of polymers seems abstract to many pupils, but this lesson turns them into a fun building game. Scholars use dice and building pieces to build polymers. Then, they determine the theoretical and experimental weight...

Knowing what farmers are feeding livestock is just smart business. A WebQuest lesson helps learners build an understanding of the relationship between amino acids, nitrogen, and protein. With interactive instruction,...

Covering the molecular interactions involved with DNA packing and the control of gene activity in depth, this slideshow is useful for higher-level biology students. The biochemical components of protein translation are diagrammed and...

In this matter and energy instructional activity, students identify substances as solids, liquids or gases, they use the kinetic theory to describe the motion of particles and they explain the conservation of mass and energy when a...

In this chemical reactions practice learning exercise, students balance 6 equations and give the name of the reactants and the products. In addition, students balance 3 equations and determine the molecular formula and the molecular...

Upcoming chemists construct atom or molecule models out of candy. This is a classic idea that learners really enjoy; however, this lesson plan is vague. There is no instruction about the structure of atoms or molecules. Make sure you...

Beginning chemists examine a collection of elements and compounds as they are introduced to the periodic table. The lesson plan is not cohesive and does not provide detailed instructions on how to teach it. However, it does includes a...

To wrap up your year of general chemistry, have lab groups compete in a tot wire chemical vapor deposition (HWCVD) competition. With their foundation in chemical nomenclature, stoichiometry, and gas laws, each group completes several...

Because of the work of John Dalton, we are able to write formulas for compounds. The hands-on experiment has scholars prepare a compound from its elements. Using mass data, individuals write the empirical formula for the compound.

No practice problems are given on this handout; it is a detailed list of concepts to know and tips for working related problems in chemistry. Give this to learners as a study guide, or use it early in your career as a chemistry...

Do you have mole problems? If so, call Avogadro at 602-2140. The lesson starts with pupils working independently to solve for molar mass of ionic compounds. Then they learn to solve for percent composition and later perform an...

Atomic theory, experiments that contributed to our knowledge of matter, atomic structure, isotopes, and ions are covered in these 33 slides. Quality diagrams and labeled charts will help activate understanding. The presentation concludes...

Two activities explore the concept of size, especially small sizes down to the nano. Scholars practice determining volume, mass, and density and calculate exponential increases and decreases. They then predict and test the effect of size...

In this worksheet, students calculate the density, molar mass, and volume of given word problems. Students also calculate the partial pressure of the gases given in the particular problem.

Students observe the 'pouring' of a gas. They compare the masses (weights) and densities of two gases. Pupils define the following terms: matter, mass, and density. Students answer questions after watching the demonstration.

In this chemistry worksheet, students look for the weight of acid and examine its mass using chemical equations and a laboratory procedure.
