If you have taught the first lesson in this mini unit, learners already know that cabbage juice and vinegar cause chemical changes in some materials. Now, they get a chance to use them to compare the liquids' reactions to five known and...

Here is a 25-question Jeopardy-style game to use as a review with physical science classes on elements, the periodic table, atomic structure, and basic chemical reactions. If there are any questions that you did not cover with your...

Poor Sam! His graham crackers have undergone a physical change, so he can't make his s'mores! Mia explains that their molecules haven't changed, therefore they are still graham crackers. The two teens then discuss clues that would...

This is a classic chemical reaction to use in your science class. Starch and iodine mix to cause a color change. Discuss with aspiring chemists the chemical and physical changes that occur as you demonstrate.

This is a classic chemical reaction to use in your science class. Starch and iodine mix to cause a color change. Discuss with aspiring chemists the chemical and physical changes that occur as you demonstrate.

Give your charges a charge with this clip on chemical reactions! Bill initiates some pretty flashy chemical reactions that you most likely won't be doing in your classroom. When you are teaching the difference between physical and...

Twenty changes have occurred today, and Dr. Sparks needs help sorting them out! First-time physical science fans simply decide whether each represents a physical or a chemical change. The handout would make a useful quiz or review...

First-time physical scientists explore chemical change with three activities. They combine calcium chloride with water, fertilizer with water, and baking soda with copper sulfate. For each, they describe what happens and write down the...

Budding chemists achieve a basic understanding of the role of heat in chemical reactions. An online worksheet gives learners instructions and questions to answer as they investigate the Chem4Kids website and perform a hands-on lab...

When your upper elementary or middle school class is learning about chemical changes, these activities help demonstrate the concepts. In Part A, they submerge and place a nail partially underwater, then after a week they make...

Little chemists observe the effects of acid on calcium carbonate as an example of chemical change. As a demonstration you will place a raw egg in vinegar overnight, and as a lab activity, learners drip vinegar onto a piece of chalk....

Third graders investigate how temperature and motion (energy) create a chemical change that turns cream ( a liquid) into butter (a solid). They create a class pictograph of their favorite mils choices (white, chocolate, or strawberry)...

A simple assignment that reviews physical and chemical changes with your physical science pupils. They fill in the blanks in a paragraph about each. In addition, they list three examples of each. Without a word bank, it may prove...

A 12-page midterm exam sample can be given to young scientists in preparation for an exam. This particular installment is geared toward a class that delves into both ecology and chemistry concepts. There is no way to separate the 50...

"Up and Atom" is a mini-unit introducing middle-schoolers to the wonders of elements. Participants draw atom models, examine the periodic table, compare samples of metals to nonmetals, identify unknown elements, and more! The beginning...

Students explore matter and its chemical and physical changes.  In this exploring matter lesson students participate in an activity where they find examples of physical and physical changes of matter in food. 

Though it states that it is a worksheet, this technically is a set of directions for a series of six activities exploring physical and chemical changes. Chemistry or introductory physical science aces examine carbon dioxide production of...

A combination of lab activities, class discussion, and teacher demonstration shows chemistry aces the difference between physical and chemical changes. Participants track the mass of a candle as it burns, rotate through a series of...

Does the change in energy of matter lead to a change in mass? Upcoming chemists compare the mass of equal-volume, but different-temperature liquids and materials both before and after a chemical reaction has occurred. In another...

A collection of ten slides reveals bright graphics and photos. Though the title is "Properties of Matter," the content is incoherent. You will find a couple of slides on chemical reactions, a few on the example of the S.S. Hindenburg...

In this chemical equations activity, students review chemical changes, define catalysts and coefficients, and review the five general types of reactions. This activity has 12 fill in the blank and 42 short answer questions.

Consider our energy sources: wood, coal, oil, uranium. Learners compare the pollution to energy produced for each. They practice fractional distillation of an alcohol/water mixture to simulate the process of refining crude oil....

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...

A full-fledged practice final prepares pupils for their general chemistry final exam. If they complete these 57 multiple-choice questions correctly, they will be well-prepared. Note: even though the questions are multiple-choice, there...
