Viewers learn how to identify the substances in a chemical reaction, how to balance it, and the different types of chemical reactions by watching a presentation that also includes a review of monomers and polymers. The presentation...

Once I told a chemistry joke, but there was no reaction. Get young chemists involved in changes and reactions with a presentation that begins with physical and chemical changes and chemical reactions. It moves on to chemical...

Technology can help save money and add convenience. The resource offers a free textbook for a complete Chemistry course. The text begins with a review of the scientific method and continues to explain topics such as chemical bonding,...

You didn't know you'd find moles in chemistry class! Through the introduction of moles and molar volume at STP, classes see how to calculate moles using a given chemical equation. The presentation includes a short review of ions in...

In an electrolytic cell, electrical energy is converted into chemical energy, the exact opposite of a battery! Lesson 15 in a series of 36 explores electrochemistry. Participants begin by reading and discussing oxidation/reduction...

On Earth, a candle flame points up, but on the International Space Station, it forms a sphere. Young scientists practice their skills by recording observations before, during, and after a candle burns. Chemical and physical...

Stop wasting energy searching for physics resources, this comprehensive collection of worksheets has you covered. Starting with introductions to the scientific method, dimensional analysis, and graphing data, these skills practice...

Young chemists grow ionic crystals, metallic crystals, and supersaturated crystals in three different lab experiments. Observing these under a microscope allows pupils to compare the various structures. 

What is a reasonable percent yield in the manufacturing process? Scholars develop a process for producing chalk in the third lesson of a six-part series. Then, they must determine the theoretical and percent yield. Discussions about...

What did one titration say to the other titration? We should meet at the end point! Young chemists perform four experiments: dilute solution, neutralization, titration, and figuring pH/pOH. 

What is a chemist's favorite plant? Stoichiome Tree! Scholars produce hydrogen gas by reacting magnesium with hydrochloric acid. Then they calculate the molar volume of the gas produced before answering assessment questions.
