Fifth graders explore volcanoes and the rocks they produce using the Internet. The lab portion of the lesson prompts young scientists to compare and describe igneous rocks. Next, they critique a pair or more of...

Students will discuss the de Brogile Hypothesis and state the circumstances under which the wave nature of matter is observed. They will also calculate the wavelengths of matter waves.

Students discuss the mass-energy relationship based on Einstein's work. They calculate the energy released in various scenerios and sketch diagrams for the Lyman, Balmer and Pfund Series. In groups, they discuss the role of photons and...

This lesson will define hydrogen bonding. It is 1 of 2 in the series titled "Hydrogen Bonding Definition."

Resource investigates how Bohr's model of hydrogen explains atomic emission spectra.

[Free Registration/Login may be required to access all resource tools.] Explains hydrogen bonds including why they form and changes of state.

This lesson will explain how to identify molecules that exhibit hydrogen bonding. It is 1 of 2 in the series titled "Hydrogen Bonding Identification."

The team at Periodicvideos has created a TED-Ed Lesson for every element of the periodic table. This one is about hydrogen and an exploding balloon. But what creates the fireball? [7:17]

1HNMR theory begins in the nucleus of hydrogen. Complete this tutorial on the 1HNMR spectrum graph to learn about the number of equivalent hydrogens, b) the chemical environment of each hydrogen type and c) the number of neighbouring...

Ever wonder why solid ice floats in liquid water? In this video lecture you will explore the special properties of water. Learn "the science behind how hydrogen bonds keep the ice in your glass (and the polar ice caps) afloat". At the...

[Free Registration/Login may be required to access all resource tools.] In the following online tutorial students will describe the structure and polarity of a water molecule. They will also describe the hydrogen bonding that occurs in...

[Free Registration/Login may be required to access all resource tools.] The following online tutorial describes how the electronegativity difference between two atoms in a covalent bond results in the formation of a nonpolar covalent,...

[Free Registration/Login may be required to access all resource tools.] In this module, students will define pH and use the hydrogen or hydroxide ion concentrations to calculate the pH of a solution. They will also differentiate among...

This lesson will introduce the molecular structure of water, including the Hydrogen atoms, Oxygen atoms, and types of bonds. It is 2 of 4 in the series titled "Molecular Structure of Water."

[Free Registration/Login may be required to access all resource tools.] Covers physical properties of water, hydrogen bonding, surface tension, and vapor pressure.

Asteroid strikes get all the coverage, but "Medea Hypothesis" author Peter Ward argues that most of Earth's mass extinctions were caused by lowly bacteria. The culprit, a poison called hydrogen sulfide, may have an interesting...

This module simulates the excitation of hydrogen atoms through irradiation with electromagnetic radiation of different wavelengths.

[Free Registration/Login may be required to access all resource tools.] The chemical and physical properties of water are examined in this lesson, including the role of hydrogen bonds in determining water's properties. The importance of...
