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...

Fifth graders watch a video about physical and chemical changes. In groups, they participate in a variety of activities involving color. They write their observations in a journal. To end the lesson, they use a checklist to classify...

Students comprehend that a chemcial change produce substances with a different composition and physical and chemcial properties. They state the differences between physical and chemical changes. Pupils observe changes that occur during...

In this physical and chemical properties worksheet, students read a 2 page article, identify 10 changes as physical or chemical characteristics and decide whether 3 combination of objects are chemical or physical mixtures and explain why.

Students 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...

In this chemical reaction worksheet, students investigate the results of mixing calcium chloride with sodium bicarbonate. They observe the chemical and physical changes that occur, identify the properties of the chemical before and after...

Students break into four groups, starting at different stations. Each station should take about 10 minutes depending on prior knowledge of the topic. They then rotate when everyone is finished to the next station and discuss answers of...

This is actually a 10-day mini unit on thermal energy for your high school chemists. Every avenue is taken to get learners absorbed in heat: a pretest, a PowerPoint presentation, Internet exploration, demonstrations, lab activities, and...

Does the size of a sample change the physical properties of that substance? It turns out it can! Young scientists combine physics and chemistry to synthesize CdSe quantum dots and record their color properties. Learners should...

In this properties worksheet, students compare and contrast physical properties and chemical properties. This worksheet is a graphic organizer.

Fifth graders compare physical and chemical changes. They perform a simulation experiment/activity that replicates what happens in the stomach as food is digested by stomach acids.

For this chemical and physical change worksheet, students conduct a variety of experiments with unknown solutions and make observations. Students determine if the properties of the solutions have changed and if there is...

Eighth graders explore the physical change of matter. As a class, they discuss their favorite super hero and determine if the hero undergoes a physical or chemical change. Students examine the change of state and phase change. In groups,...

In this chemistry overview worksheet, students compare atoms and molecules, intensive and extensive property, and physical and chemical change. This worksheet has 12 short answer questions and 3 problems to solve.

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.

The Law of Conservation of Matter can be complex for young scientists to fully grasp. Use this experiment to help simplify the process as pupils perform two experiments to determine mass: one that melts a substance and the other that...

If you aren't part of the solution, you are part of the precipitate! Young chemists learn about single and double displacement reactions including precipitation reactions, neutralization reactions, and gas forming reactions. They perform...

A table of the physical properties of metals and non-metals opens this high-school chemistry handout. Also covered are the chemical properties of metals and non-metals, reactivity, and fossil fuels. There are no specific questions to...

Scholars learn about heat release in phase changes. They perform calculations as they compare and contrast a science fiction passage and a home heating application.

Household materials can be used for more than cleaning! In this collaborative experiment, emerging chemists use products such as vinegar and liquid antacid to explore chemical reactions that commonly occur in the human body.

Examine the nature of landfills through experimentation. Scholars build miniature landfills and monitor changes over a six-week period. Observations allow individuals to draw conclusions about the different types of trash and their...

Fifth graders compare and identify variables that affect the rate of a chemical change using Alka-Seltzer, water, ice, and hot water. They time how long each variable takes to pop the canister into the air, and record the results on a...

Fifth graders watch a demonstration in which a balloon is inflated using the gas created by combining vinegar and baking soda. Then, in groups, they combine various assigned substances and watch and record the results.

Is it easy to make snow? Scholars use critical thinking skills as they investigate the concept of polymers by making snow. The class tests several different variables and takes measurements over the course of several days. They then...
