In this isotopes review sheet, students determine the atomic mass for three elements and they answer questions about isotopes.

Seventh graders, in groups, complete an Isotopes model and notice that atomic masses are decimal numbers. These masses are an average of all the isotopes of that element.

Students write the electron configuration of elements in the ground state. In this chemistry lesson, students draw how subatomic particles are arranged in the atom. They construct Lewis dot diagrams of valence electrons.

In this chemistry instructional activity, students identify and write how many significant figures they would use for each problem. Then they round the answers to the appropriate number of significant figures. Finally, students calculate...

For this AP Chemistry worksheet, students apply concepts of electron configuration to accurately answer the questions provided. Students also draw Lewis structures of the given elements. Students estimate the enthalpy of formation as...

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.

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.

How can one easily classify metals, nonmetals, and metalloids? Pupils answer this question as they experiment with unknown substances and perform tests on conductivity, brittleness, and malleability to determine...

Young chemists have unknown compounds they need to sort. Performing three different tests on each, the chemical behaviors they observe become the basis for data analysis. 

Illuminate your physics class with this examination of a photovoltaic cell. Teach the structure and operation of the device using a diagram. Then make a human-powered, larger-than-life sized model of a PV cell. Learners become electrons...

In this drawing Lewis structures worksheet, students read about the 5 steps taken to draw Lewis structures for atoms and molecules. These include identifying the valence electrons, placing pairs of electrons between atoms to be bonded,...

Facilitate learning by using small objects to teach the principles of atomic mass in your science class. Pupils determine the average mass of varying beans as they perform a series of competitive experiments. They gather data and...

Abracadabra! Provide your class with the tools to perform a chemical "magic show" as they predict the charges of various ions, determine ionic compound formulas, and make observations to determine when a chemical reaction between...

The goal of this science lesson is to have youngsters be able to identify the physical and chemical changes in the carbon cycle, and water cycle due to weathering. The in-class inquiry/experiment is quite interesting and easy to...

Students recognize different consumer products, found in and around the home, that have reactive or denaturing properties when used together. They explore chemical and physical properties of each product by identifying chemical formulas...

What is a chemist's favorite plant? Stoichiome Tree! Scholars produce hydrogen gas by reacting magnesium with hydrochloric acid. Then they calculate the molar volume of the gas produced before answering assessment questions. 

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...

Explain the importance of radioactive half-life as your high school biologists demonstrate the concept by performing a series of steps designed to simulate radioactive decay. Pupils use pennies to perform an experiment and gather data....

Using toothpicks, marshmallows, and round colored sticky dots, physical science enthusiasts build models of an atomic nucleus. In this eighth grade chemistry lesson plan, they play an atom-naming game with the models that they have...

How are chemical bonds similar and how are they different? Provide your young chemists with the resources to more thoroughly understand the concepts of ionic and covalent bonds. Pupils research these topics, diagram examples of each...

Every region has a renewable resource that can be used to make hydrogen. But, what is hydrogen and why can it be used as an energy source? Find out with a presentation that answers these questions and then discusses where hydrogen is...

Bacteria outnumber all other forms of life on Earth. Scholars observe the growth of bacteria in petri dishes to understand their role in maintaining good health. Then, they observe the growth of bacteria after they introduce...

A splendid chart of information about chemical bonding tops the first page. In it you will find information on London forces, permanent dipoles, hydrogen bonds, ionic bonds, and covalent bonds. A four-step process for assigning...

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...
