Young scholars observe the periodic table and draw the Lewis Dot Diagram.  In this investigative lesson students construct information on several elements including the Lewis Dot Formation and take a quiz on the information they...

There are different types of radioactive decay, and alpha decay is when there are too many protons in a nucleus. Here is a simulation that shows alpha particles being emitted from a polonium nucleus. Learners see how radioactive decay...

How much energy is required to break apart an atomic nucleus and does it vary based on the type of atom? Scholars virtually experiment with a linear accelerator in order to answer these questions. They alter the voltage, length of the...

In this atoms worksheet, students determine an atoms based on its protons, and neutrons. Students determine the electron levels for the oxygen atom. This worksheet has 1 multiple choice, 4 fill in the blank, and 13 short answer questions.

In this atoms worksheet, students 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 chemistry instructional activity, students fill in the blanks with the correct word from the word list. They examine the arrangement of elements in the periodic table.

For this atom worksheet, students review the structure of an atom. Students also explore radioactive elements and quarks. This worksheet has 10 fill in the blank, 6 true or false, 1 short answer, and 3 multiple choice questions.

In this science instructional activity, students choose the multiple choice answer that best defines each of 15 science related vocabulary words.

Fifth graders investigate the structure of matter. They examine pictures of atoms and molecules and discuss their relationships, and construct a model of a molecule using toothpicks and gumdrops.

For this stars worksheet, students read about the different stages in the life cycle of a star. Then students complete 3 short answer questions.

Students explore neurological disorders. They examine the presence and absence of discernible genes. Students describe neruological diseases and draw faces of affected persons. They play a human neurology disorders learning game.

Neat! Show your physics class exactly how Ernest Rutherford fired alpha particles at a piece of gold foil and so determined that most of an atom is composed of empty space. Not just a slide show, but almost an animation, this...

The creator of this collection of chemistry slides is clever! Electron configuration is explained as, click-by-click, orbitals are displayed and then each is subsequently filled with the proper amount of electrons. After the progression,...

In this periodic table worksheet, students review atomic mass, molar mass, and percent composition of compounds. Then students complete 4 problems.

For this atoms worksheet, high schoolers will review the characteristics of elements, atoms, and isotopes. Then students will compare the difference between ionic and covalent bonds. Finally, high schoolers will balance a chemical...

In this science worksheet, students identify and locate vocabulary words related to various sciences. There are 20 words located in the word search.

In this bonding worksheet, students read about the two different types of chemical bonding: ionic and covalent bonds. Students review ion notation and oxidation numbers. This worksheet has 24 fill in the blank, 2 drawings, and 4 short...

In this universe worksheet, students read about the big bang theory and the evolution of the stars from the elements. Students answer four critical thinking questions about the beginnings of our universe.

In this periodic table worksheet, students complete a chart with the appropriate element symbol, the atomic mass and the atomic number. They classify elements by their groups and as metals, nonmetals or semi-metals. They also answer two...

A huge slide show provides a review of almost every topic there is to cover in basic chemistry! Your young scientists will be interested to see each illustration and example given. The appearance of the 120 slides varies greatly, most...

Eighth graders discuss and write about what led up to the discovery of the atom. Students label proton, nucleus, electron, and neutron in their notes. Students take notes on electron shells and how different atoms have different...

In this chemistry review worksheet, students answer and solve 95 questions about chemical reactions, hydrocarbons, functional groups, moles, acids and bases and solutions.

Starting with a recap of atomic structure, these slides continue by comparing different isotopes of uranium and explaining which are stable and which have a decay period and emit alpha or beta particles. Gamma decay is just mentioned on...

A great way to learn about molecular structures is to make a model. Gumdrops and toothpicks are used to construct crystal models. The models are based on theories of crystal shapes that occur because of positive and or negatively charged...
