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...

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...

This PowerPoint is a gem! Seventy-eight slides present an entire introduction to matter in bullet-point fashion. Viewers learn about everything from mass and inertia to phase changes and gas laws! The only glitch is that the links to...

Sugar crystal growth is observed as an example of physical change and cabbage juice pH indicator is used to demonstrate chemical change. The crystal growth is tracked over five days. The cabbage juice experiment is involved and can also...

After viewing a short video about property changes, preteen scientists watch you combine different materials, and then perform two of their own experiments. For each demonstration or activity, they are to determine whether a physical or...

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...

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....

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...

Written as a textbook reading guide, this worksheet covers foundational concepts for any general chemistry class. From scientific method, measurement, and temperature, to more chemistry-specific topics like chemical and physical changes,...

A comprehensive practice exam, this resource covers many areas of chemistry. The test includes 71 multiple choice questions on topics such as problem solving, chemical equations, chemical formulas, thermodynamics, acids and bases, and...

These fourteen questions require learners to calculate energy change in joules in certain circumstances and after specific reactions. A nice sheet to review math calculations and chemical enthalpy.

In this chemistry review worksheet, students identify chemical changes, isotopes, ions, and chemical bonds. This worksheet has 32 multiple choice questions.

A list of questions that will test the understanding of nuclear chemistry. There are some definitions of terminology required and then generic equations that clarify nuclear transmutation. Pupils should also be able to describe the...

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.

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...

Learners 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 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...
