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...

Compounds take on different properties than their elemental components. How can scientists determine those elements? A lab-based activity has learners explore several double replacement reactions to analyze compounds qualitatively. They...

What must a sentence contain in order to be complete? What different types of sentences exist? Look at declarative, interrogative, and exclamatory sentences with this 17-slide presentation. Several example sentences are shown, and the...

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)...

If you use this as an outline for your chemistry lecture on metals, your young chemists will absorb a well-rounded overview. This is not a worksheet per se, but a useful summary of the behavior of metals. Save yourself some planning and...

What's smaller than a kiwi seed? Atoms! Basic atomic structure is detailed for beginning chemists in a light-hearted animation. Protons and neutrons are explained as part of the nucleus, and so are electrons that encircle the nucleus....

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...

Max Born and Fritz Haber developed the Born-Haber cycle in 1916, which is used for measuring enthalpy that otherwise couldn't be measured. Young scientists solve four matching puzzles using their knowledge of the stages, standard...

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...

A flashy PowerPoint includes clear summaries of atomic structure and electronic configuration. Dot and cross diagrams will help viewers learn how to draw an atom. As a result, learners should be more clear how electronic configuration...

Three experiments involving pennies help young chemists see the chemical reactions between copper and other elements. The first experiment is rhetorical (it prompts learners to leave a bright penny out for a year) but the second two...

The process for balancing chemical equations is stepped through slide by slide in this presentation. For some strange reason, the subscripts for certain elements are not dropped down on the first slide only, so you may want to copy the...

In this periodic table I quiz, students select the best answer to the given questions. Students apply their knowledge of the periodic table and the arrangement to correctly answer the questions presented.

In this etymology worksheet, students read about the history of naming words and how words are named. They think critically by answering three questions about the meaning of words, etymologies and the derivation of words.

In this chemistry science worksheet, students identify the parts of a chemical reactions. Students name the major particles of the atom. Students apply knowledge about the atom, theories, and models.

In this atoms learning exercise, high schoolers circle the term in parentheses that makes the 20 statements correct. The statements review the parts of an atom, isotopes, and basic matter principles.

In this molecules, moles and molar masses worksheet, students find the atomic masses of 8 elements, they write the formulas for 6 diagrams of molecules and they find the molecular masses of 12 compounds. Students also find the fraction...

In this molecular mass and percent composition activity, high schoolers complete 5 sections where they determine atomic masses of given elements, they determine formula masses for given molecules, they find the molecular mass of 12...

Students perform varied activities as part of a layered curriculum unit: They write and perform a skit that outlines the evolution of the model of the atom. The script is submitted to the teacher for review before performance.

In this chemistry worksheet, learners calculate specific changes that take place with different chemical reactions. Students indicate whether the reactions are endothermic or exothermic and spontaneous or nonspontaneous.

Bone-crusher. Troll-wife. Battle-sweat. Blood-worm. What study of Beowulf would be complete without offering readers of this Old English epic poem an opportunity to craft their own kennings and epithets? Provide individuals with a copy...

What are alloys, and why do we use them? Through a series of interactive puzzles, scholars examine the components and uses of several common alloys. The accompanying teacher's resources provide support in using the lesson, printable...

Teach young engineers that all machines, no matter how complicated or complex, are made up of just six simple devices with this hands-on physical science lesson. Using the included templates, students first create paper models of...

Winning a spin game is random chance, right? Pupils create a table to determine the sample space of spinning two spinners. Individuals determine the probability of winning a game and then modify the spinners to increase the probability...
