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...

In a neat and straightforward manner, this PowerPoint delivers basic introductory information on the properties of matter, physical and chemical changes, and pure substances vs. mixtures. It also defines the states of matter. For some...

Although preparation-intensive, this would be an unforgettable experience in materials engineering. Stimulate learners' curiosity with a slide show and then introduce them to the components of concrete. Small groups mix and pour concrete...

A total of five experiments lead chemistry pros to understand the difference between physical and chemical change. They also experiment with exothermic reaction factors that affect rate of reaction. The procedures are not written in the...

Students explore physical and chemical changes. In this chemistry lesson plan, students will go outside to observe changes seen in nature. Students will then work in the lab to identify changes at different stations prior to doing a...

Middle schoolers 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. ...

Students measure the heat of physical and chemical changes in reactions.  In this chemistry lesson students determine at what extent changes emit or absorb heat. 

Fifth graders conduct an experiment.  In this changing matter lesson, 5th graders receive a cup of crystals, record their observations, add water to the crystals and record new observations. Students then discuss the differences...

In this chemical reactions worksheet, learners answer follow up questions to a lab where they were observing chemical changes in reactions after mixing products such as hydrochloric acid and sodium bicarbonate. They answer six questions...

In this classification of changes worksheet, students identify each example as either chemical or physical changes. Students also classify other examples as either element, compound, solution, colloid, or suspensions. In the other...

In this chemistry practice activity, students solve sixteen problems including identifying chemical and physical changes, calculating numbers with significant figures, naming compounds and writing formulas and converting from one unit to...

Learners apply their comprehension of colligative properties to real-world situations. They review the concepts of physical and chemical changes. Students are reminded that science is used extensively in food-production. They are...

Students observe what happens when sugar is dissolved in water and when it is heated. They weigh the products after each of the two experiments on a balance scale. Pupils distinguish between physical and chemical changes. Students are...

Third graders explore forms of matter through reading, hands-on science activities, and research using the Internet. Students create a booklet, directions given, that they title and decorate, to later serve as a review visualization...

Students define the words "reversible" and "irreversible." They complete a worksheet that shows a number of changes. Students must decide which are reversible and which are irreversible.
