Bleach Chemical Reactions

More than 90 percent of chemical products are made using a catalyst. Lesson demonstrates the way a catalyst changes the rate of reaction without altering the chemical reaction. A catalyst doesn't appear as a reactant or a product, yet it...

Investigate the Law of Conservation of Mass through a lab exploration. Individuals combine materials to initiate chemical reactions. They monitor for signs of reactions and measure the masses before and after the reactions for comparison.

Students distinguish between physical changes and chemical changes. They comprehend that chemical reactions produce new substances with compositions and properites which are different than those of the starting materials. Pupils also...

In this chemical reactions worksheet, students follow a flow chart to determine what type of reaction is occurring. Students then classify reactions and balance the equations. This worksheet has 2 short answer and 10 fill in the blank.

Fourth graders examine and identify chemical and physical changes in a variety of substances. They observe a vinegar and baking soda demonstration, and a water, laundry detergent, and Epsom salt mixture demonstration. They discuss the...

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...

Unique properties of hydrogen, its production, and reaction with other elements make this slide show uncommon. The appearance, however, is common with plain white background and only black and red font, a formatting issue on the second...

When was the last time your class saw a catalyst in action? Chemistry scholars observe an activated complex during an engaging experiment. Through both color change and evolution of a gas, individuals gain insight into the...

Students identify the signs that a chemical reaction took place. In this chemistry lesson, students role play the movement of different molecules of matter. They classify matter according to their properties.

Sixth graders combine chemicals to create a chemical change. For this chemicals lesson plan, 6th graders will investigate characteristics of chemical change by combining chemicals. They will learn that color change is an indicator of...
