Students demonstrate radioactive decay using candy corns. In this Physics lesson, students make predictions, collect data and form conclusions about patterns in radioactive decay.

In this chemical bonding worksheet, students read about the invisible killer, dihydrogen monoxide. Students read about the products it is used in and the problems it causes to the environment. Then students complete 19 short answer...

How do you get a theorem named after you? Euler knows what it takes! The third lesson of five asks pupils to use an interactive activity to compare the faces, vertices, and edges of seven different three-dimensional solids. They use...

Students investigate vocabulary words associated with electricity.  In this electrical lesson, students utilize the Internet to research what electricity is and how it works.  Students create an actual circuit in class using a...

Students identify the different states of matter. In this chemistry lesson, students differentiate the physical properties of the three states. They apply what they learned by playing a team game at the end of the lesson.

Students predict the shape of molecules using VSEPR theory. In this chemistry lesson, students differentiate a polar and nonpolar molecule. They discuss why water's polarity is very important.

Students calculate the values of electron binding energies. In this physics lesson, students solve for different wavelength characteristics of X-rays. They present their findings to the class.

Students calculate the Balmer series. In this physics lesson, students observe hydrogen lamp spectra using spectrometers. They calculate wavelength and compare them with their theoretical calculations.

A video and a short quiz on the parts of an atom, the periodic table, and molecules.

Understand the basic structure of atoms and molecules in the Earth's crust.

Learn how basic elements form molecules to support life.

Read common questions and answers about atoms, elements and molecules.

This lesson introduces students to scientific models. The students will learn how models of the atom have changed as new evidence is gathered. The students will also learn about the current model of the atom. Each student will make a...

Through this reading, students will learn that a substance's properties arise from its molecular structure, not from how it's made (i.e., synthesized by people or found in nature). There is no fundamental difference between natural and...
