Electrify your science class with this simple electrolysis experiment. After first reading about hydrogen and its potential as an alternative energy source, a demonstration is performed showing young scientists how water molecules can be...

Get a surprised reaction from trying out the chemical reaction. Scholars conduct a chemical experiment by adding yeast to hydrogen peroxide and dish soap in a plastic bottle. They learn that yeast contains a catalase enzyme that releases...

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.

My name is Bond, Hydrogen Bond. Written for distance scholars working on chemistry at the high school level, the lesson includes eight weeks worth of material divided into six parts: substances you use, mixing it up, your skin, what's...

Sure, your learners know water is made up of two molecules, but watching them separate helps the class see the construction like never before. This resource provides directions on how to build a simple electrolysis device using a...

Let knowledge of chemistry flow like water. Future scientists conduct two different experiments to investigate the properties of water. They learn about surface tension and cohesion as they see how many drops of water they can place on a...

Does the mention of proteins and polypeptide relationships in your classroom result in mass confusion? Does the attempt to teach this important concept generate multiple questions and, at times, lead to a room filled with blank...

Science teams make models of four different hydrocarbon compounds that we commonly use for fuel. Then they demonstrate chemical reactions that result when energy is produced. This can be used as an enrichment when your class is studying...

Young scientists know that water is H2O, but can they prove it? Through a simple electrolysis of water demonstration, scholars see the two gases produced as a result of a chemical reaction. Because this reaction doesn't happen...

Break down light into spectra. Scholars learn how atoms emit and absorb photons and come to understand how this process allows scientists to identify different atoms based on either absorption lines or emission lines. Learners then...

Here is a six-page exploration that will spark interest in the periodic table of elements. After reading a diagram-supported explanation of the periodic table's organization, pupils answer questions to familiarize themselves with it. To...

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...

What's in soil? Young scientists study the pH levels of soil from their school yard. They observe the land and area the soil came from to decide if location has anything to do with acidity level.

Where does the mass for a growing tree come from? Scholars consider a few different hypotheses and guess which is correct. They then analyze data from different experiments to understand which concepts science supports.

Hydrogen peroxide (often used as a disinfectant) has also been approved for use in pesticides. This science fair project investigates whether hydrogen peroxide has any effects on seed germination or on roots of plant cuttings.

A site showing the structures of water and ice and explaining how they are affected by hydrogen bonds. Includes a movie animating hydrogen bond formation and disruption.

In this experiment, you will use a meterstick spectroscope to observe the emission spectrums of hydrogen, sodium, neon, helium, and mercury. Requires Java plug-in.

From the Brockport High School Physics Labs web pages. Includes an excellent graphic depicting the energy levels of a hydrogen atoms and portraying the electron level transitions for the Lyman, Balmer, and Paschen series. Includes both...

In this experiment, students generate hydrogen gas and examine its properties. Teacher's notes are included.

The New Mexico Solar Energy Association provides an article entitled, "Electrolysis: obtaining hydrogen from water - the basis for a solar-hydrogen economy". The article is medium size in length with pictures and charts throughout to help.

This lab exercise exposes students to a potentially new alternative energy source-hydrogen gas. Student teams are given a hydrogen generator and an oxygen generator. They balance the chemical equation for the combustion of hydrogen gas...

A lab activity from an AP Physics course. Students measure the energy changes associated with electron level transitions to the second energy level for hydrogen gas. Includes directions and suggestions. Ideal for a student project or lab...

Identify the composition of stars by applying the ideas of quantum theory. Investigate the field of spectroscopy, and examine the spectra of stars to locate the emission and absorption lines of hydrogen.

This experiment and video demonstration shows how students can break up water into hydrogen and oxygen gas with a simple electrolysis device.
