One for the Money
Eighth graders sort items as they are shown one at a time by the teacher. They attempt to identify the one physical trait the teacher is looking for (metal and not metal). After several objects have been shown and placed in groups, the...
Curated OER
Structure of the Atom
Students practice drawing the atomic structure of several different elements. They complete critical thinking questions about atomic structure and compare the atomic mass units for different ions and isotopes of an element.

Gases
In this gases worksheet, students review the 3 states of matter, the types of molecular motion, and the characteristics of gases. This worksheet has 30 problems to solve.
Curated OER
Chemical Reactions
Students work in groups to define chemistry vocabulary including the terms reactants, products, exothermic and endothermic. They then combine the group definitions to arrive at a consensus definition for the class. Students also listen...
Curated OER
Uranium On a Diet
Students examine how nuclear reactions differ from other chemical reactions they have studied. They add up atomic masses of both the product and reactant side of an example of uranium decomposition, demonstrating mass loss involved.
Curated OER
Pounds of Pollution
Students examine pollutants and investigate air pollution emitted by a car in a year. In this air pollution lesson plan students complete an activity and make calculations.
Curated OER
Bouncing Balls
Students create a polymer to demonstrate its properties and develop an awareness of the wide variety of uses for polymers.
Curated OER
How Can We Accurately Make Different Solutions of Different Concentrations?
Students work together to create different solutions made from different concentrations of liquids. They record and analyze their data. They answer discussion questions to complete the lesson.
Curated OER
Quantum Mechanics and Atomic Physics
Students will discuss the de Brogile Hypothesis and state the circumstances under which the wave nature of matter is observed. They will also calculate the wavelengths of matter waves.
Curated OER
Atoms, Kinetic Theory, Solids and Fluids
Students identify and describe the building blocks that make up an atom. They also compare the ages of atoms to the ages of the materials they compose,as well as, give examples that illustrate the small size of atoms.
Curated OER
Forces And Energy
Middle schoolers investigate the atom and how it is formed. They conduct research using a variety of resources and then construct a model of the atom. Then students have class discussion. The lesson includes background information for...

In this atoms worksheet, students determine an atoms based on its protons, and neutrons. Students determine the electron levels for the oxygen atom. This worksheet has 1 multiple choice, 4 fill in the blank, and 13 short answer questions.
Curated OER
Oxidation Numbers
In this oxidation numbers worksheet, students determine the oxidation number for given elements and draw Lewis Dot Diagrams. This worksheet has 6 fill in the blank and 11 short answer questions.
Curated OER
Matter and Chemical Bonding
In this chemical bonding worksheet, students read about the invisible killer, dihydrogen monoxide. Students read about the products it is used in and the problems it causes to the environment. Then students complete 19 short answer...
Curated OER
Bridge Cable Corrosion
Students investigate the corrosion of different materials in the lab. In this chemistry lesson, students construct a bridge considering different bridge designs. At the end of the lesson, they play the role of scientists and engineers...
Curated OER
Flame Test
Students conduct a flame test on different substances. In this chemistry lesson, students predict the element present based on the color emitted during the flame test. They explain how different elements produce different colors.
Curated OER
Atoms and Molecules
You can use hands on and kinesthetic activities to teach abstract concepts, such as atom and molecule lessons.
Curated OER
Detecting Magnetic Materials in "Martian" Soil
Students simulate some of the Pathfinder experiments by devising methods of collecting and measuring magnetic substances in pseudo-Martian soil. The efficiency of each of the methods used to collect materials is evaluated in this lesson.
