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.

Discover how the periodic table tells the story of its elements. Learners begin by studying the makeup of several mixtures. Their analysis leads to a discussion of elements and the periodic table. As they dig deeper, they understand the...

Fifth graders explore the differences between elements.  In this elements and atoms lesson students complete an activity that shows how chemicals react to a flame test. 

High schoolers examine the differences between elements, compounds and mixtures. Using diagrams, they compare and contrast atoms and molecules and describe various chemical reactions. They distinguish the differences between ionic and...

Students investigate the characteristics of alkaline earth metals. For this alkaline earth metals lesson plan, students experiment with a variety of alkaline earth metal compounds and perform tests to observe their properties. Students...

What makes up the air we breathe? Young scientists explore the atoms and molecules in the air. An interactive lesson allows individuals to watch the movement of the particles in the air and change the makeup from a mixture to a...

Fourth graders, in groups, compile information on groups of elements. They study Alkali Metals, Alkaline Earth Metals, Halogens, and Noble Gases.

Does the change in energy of matter lead to a change in mass? Upcoming chemists compare the mass of equal-volume, but different-temperature liquids and materials both before and after a chemical reaction has occurred. In another...

Four activities immerse beginning chemists into the world of elements. They examine the periodic table, use cobalt hydroxide to learn about chemical formulae and valence electrons. Also, they name binary compounds and examine the...

Density comes to life as investigators place soda cans into containers of various liquids to find if they sink or float. They layer different density liquids, compare densities of different gases, and more. A total of six different...

Young scholars are introduced to the elements on the Periodic Table and what is meant by element. Using the Table, they identify the name, atomic mass, number and symbol of each element. To end the activity, they discover the...

Cookies and chemical equations have a lot in common! Using cookies as a reference, scholars learn to balance chemical equations. Pieces of the cookies represent different parts of the compounds and elements. This is the sixth installment...

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...

Students examine the importance of applying the scientific knowledge of elements, mixtures, and compounds to manufacture consumer goods and conduct civil operations, such as water purification. They also practice categorizing examples...

"Up and Atom" is a mini-unit introducing middle-schoolers to the wonders of elements. Participants draw atom models, examine the periodic table, compare samples of metals to nonmetals, identify unknown elements, and more! The beginning...

Students explain how radioactive decay occurs. For this physical science lesson, students simulate radioactive half-life through an experiment. They graph their data and share their results in class.

Students find the percent of oxygen in potassium chlorate. In this percent composition lesson plan, students heat a solution of potassium chlorate using a catalyst, manganese dioxide, to decompose the potassium chlorate and release...

Students explore elements and compounds. For this lesson about elements and compounds, students will do an experiment. Students work in groups of 2-3 as they complete two separate activities. Students understand how two elements combine...

Young scholars investigate elements by by defining scientific terms.  In this Periodic Table of Elements lesson, students utilize a glass of water, and powdered fruit drink to perform a lab activity demonstrating properties of...

Eighth graders explore the chemical and physical properties of a variety of elements in a lab setting. They organize the data they collect onto a spreadsheet and then choose one element from the periodic table to research. They...

Students perform a review assignment in 3 portions to review chemistry compounds, formulas, and equations. The assignment consists of several different portions that can be used as assessments. The majority of the lesson plan is composed...

Students explore simple and compound machines. In groups of four students, they design a compound machine using K'NEX that has a stated purpose and consists of at least two simple machines.

Eighth graders read and interpret the Periodic Table. They also make decisions on how to group and arrange different kinds of matter and draw the structure of atoms of pure elements. Finally, 8th graders contrast and compare basic...

Elements, to the rescue! Scholars first review the periodic table, and then learn about the first 20 elements and their properties and uses in the fourth of six lessons in the Mixtures and Solutions unit. Applying their newfound...
