Students are presented with the problems of percentages and focus upon numbers in contrast to 100. They calculate problems with money and are engaged with the use of games as a teaching tool. Students also interpret data as presented in...

In this chemistry worksheet, students identify the process of Stoichiometry and use it to calculate various chemical reactions similar to that of a recipe. In addition, they identify a connection between isoamyl alcohol and the product...

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...

In this stoichiometry worksheet, students use balanced equations for chemical reactions to determine the percent yield and the mass of product produced. This worksheet has five problems to solve.

Many people confuse atomic mass and atomic numbers. The sixth of seven lessons in a unit requires scholars to find the weight of different groups of pennies. Then, they must solve how many of each type of penny exists in a closed system...

In this science instructional activity, students read two example problems that include a problem, observation, and conclusion. Students also answer 2 questions using inductive reasoning.

In this calorimetry lab, students apply the information read about a calorimeter to conduct a scientific investigation. Students record their data in a chart. Students use the information from the chart to calculate specific heat of...

Stoichiometry sounds complicated, but it really means the study of the amount of substances involved in a reaction. The sixth lesson in an 11-part series has scholars use stoichiometry to find the theoretical yield of a reaction. Then,...

In this chemistry instructional activity, students determine the oxidizing agent and the reducing agent in each stated problem. Then they determine the molarity of acetic acid. Students also use the previous activities to predict whether...

In this solutions worksheet, students solve fifteen problems including finding molar concentrations, writing net ionic equations, determining molarity of solutions, identifying oxidized and reduced agents and finding mass percent of...

What happens when you combine 6.022 times 10 to the 23 piles of dirt into one? You make a mountain out of a mole hill. Scholars use dehydration to obtain percent composition and then calculate the molarity of the original...

In this renewable energy worksheet, students put an X on their opinion on the energy source that will help the Earth's problems. Students have 5 energy sources to choose from and then complete math problems based on the results.
