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

High schoolers demonstrate that isotopes of an element have different masses. They illustrate atomic mass and neutrons. The periodic table is examined in length. Display of a collection of atoms is surveyed.

Students examine the concepts of isotopes and atoms.  In this powerpoint lesson, students see the balance in numbers  of protons, neutrons, and electrons create isotopes and ions of certain atoms.

Students write the electron configuration of elements in the ground state. In this chemistry lesson, students draw how subatomic particles are arranged in the atom. They construct Lewis dot diagrams of valence electrons.

Ninth graders explain how atoms and molecules form different substances during chemical reactions and how these processes require losing, gaining or sharing electrons. They correctly write chemical formulas and show how a balanced...

Middle schoolers investigate the atom and how it is formed. They conduct research using a variety of resources and then construct a model of the atom. Then students have class discussion. The lesson includes background information for...

Student uses Schrodinger's equation applied to a single electron Hydrogen atom. They use angular and radial portions equation to answer questions. Student use a model to answer equation questions.

Students study the basic structure of the atom. In this chemistry activity, students explain how colors relate to energy that electrons emit. They calculate energy of the emitted photons.

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...

An engaging activity enlightens young chemists in this lesson plan on atomic structure. They play musical chairs through a series of concentric circles that represent electon orbitals. A laundry basket in the middle holds the protons and...

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,...

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...

Explain the importance of radioactive half-life as your high school biologists demonstrate the concept by performing a series of steps designed to simulate radioactive decay. Pupils use pennies to perform an experiment and gather data....

Abracadabra! Provide your class with the tools to perform a chemical "magic show" as they predict the charges of various ions, determine ionic compound formulas, and make observations to determine when a chemical reaction between...

People have been using solar energy for many generations to dry crops, heat homes, and for light. This presentation explains how now it is possible to capture the solar energy and store it for future use, details how and where...

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...

Did you know the word energy comes from energeia, a Greek word? Introduce learners to the four types of potential energy, five types of kinetic energy, and energy transformation with a presentation about where we get our energy and...

An extremely thorough presentation walks new chemists through the basics of matter. There really isn't a unifying theme, however So many topics are covered: forces, elements, atomic structure, chemical properties, compounds, quarks,...

Here is an interesting science lesson/activity which has learners working in groups in order to simulate experiments done at the Jefferson Science Lab. In this one, groups use a pie tin, a Hula Hoops, a marble, and a magic marker to...

Without water there would be no life on this planet. Biology learners find out why by reading this handout. Create a worksheet of questions to answer after the reading. Follow it up with quick demonstrations or laboratory activities that...

Students determine what plasma is and why the sun is made up of plasma. They recognize situations where plasmas are found in nature and made by man. They discuss why the sun is a huge ball of plasma and if there are different levels of...

Food always gets attention! Model atomic structure using fruit loops to represent the subatomic particles. After building models, scholars create ionic bonds using their models. Finally, they use these concepts to create a periodic...

Electrons flow from negative to positive, but the general consensus is that current flows from positive to negative. Scholars explore current through construction of circuits in both series and parallel. The focus is on voltage,...

Start this lesson with a bang! The eighth in a 13-part series of lessons explains the origin of elements beginning with the Big Bang Theory. The reading describes the formation of elements hydrogen through uranium.
