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...

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...

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...

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...

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

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...

Students 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...

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

"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...

Future chemists practice laboratory techniques by creating a monochloramine solution. The objectives are to use of dilution, 9concentration, and measurement skills and to prepare a solution that will be used in a water treatment...

What does size have to do with it? Learners analyze different mixtures, both homogeneous and heterogeneous, to discover the properties related to the size of their particles. The activity connects these properties to those of...

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...

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...

Eighth graders investigate chemical reactions to produce polymers. In this polymers lesson plan, 8th graders experiment with sodium silicate and ethyl alcohol to make a polymer. They also experiment with borax and glue to make a polymer....

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

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...

Young scholars explore mixtures and compounds. In this lesson plan, students do an experiment to distinguish between mixtures and compounds. Young scholars complete ten different phases of the experiment testing many different...

High schoolers 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 lesson, they discover the...

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...

Don't take for granted the technology behind power packs. Build an understanding of the chemical mechanics of a battery pack that charges your phone. The simulation allows young scientists to manipulate the type of elements in a pack and...

Should you trust the water you drink every day? The hands-on activity has scholars test water from different sources for contaminants. Pupils perform chemical testing and make conclusions about pH, hardness, iron, chlorine, lead,...

Explore the makeup of the earth's atmosphere. Using the set of specific experiments, pupils examine the main elements and compounds present in the atmosphere. Their study extends to investigate the effects of atmospheric...

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...
