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...

Young scientists construct an understanding of molecular compounds in this hands-on science lesson. Using LEGO® to model the atoms of different elements, students build molecules based on the chemical formulas of common compounds.

Show young chemists what a chemical reaction looks like with two parts of a hands-on experiment. First, learners conduct a wet lab where they observe the reactants (baking soda and calcium chloride, with phenolsulfonphthalein)...

Primo Levi wrote a collection of short stories comparing his life from Italy to Auschwitz to elements in the periodic table. Pupils read an excerpt from his book and research the characteristics of various elements. Then, they make a...

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...

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.

In this elements and compounds worksheet, learners complete a Venn diagram to compare and contrast elements and compounds. They show the similarities and what is unique to elements and compounds.

Scholars use sorting cards to try to define a pure substance versus a mixture. Risk becomes reward as they observe the differences and create a flowchart sorting matter into mixtures and pure substances (elements and compounds).

Investigate color, light and excited electrons and produce waves using slinkys. Your high schoolers will observe a continuous spectrum with a prism and an overhead projector. They observe flame tests to identify elements and they observe...

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...

Using simple materials, an informative lesson demonstrates the Law of Conservation of Matter and explains how to balance chemical equations. Young chemists perform experiments, analyze reactions, and balance chemical equations...

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. 

Scholars apply concepts learned in both Algebra II and Chemistry to answer the questions on the provided worksheet. The activity allows for extra practice in both classes and helps connect concepts usually taught in isolation. The...

Try not to blind anyone with science by following the safety rules. The lesson encourages scholars to form an ionic compound from magnesium and chlorine. Then they determine the empirical formula and determine the mole ratio and percent...

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...

This is not they typical set of teacher instructions. It is an organized chart of the important organic compounds. For each, the involved elements, the name of the building block monomers, the names of polymers, extra information, and a...

In this elements and compounds worksheet, students review the physical properties of different compounds and elements using websites for information. This worksheet has 1 graphic organizer and 1 short answer question.

What happened when the chemistry teacher told a bad joke? There was no reaction! A creative take on the traditional reaction types lesson invites learners to draw their own conclusions about how compounds and elements combine. Groups...

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...

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...

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...

If you aren't part of the solution, you are part of the precipitate! Young chemists learn about single and double displacement reactions including precipitation reactions, neutralization reactions, and gas forming reactions. They perform...

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...
