Students classify compounds as ionic or covalent. In this chemical bonding lesson plan, students experiment with 6 chemical compounds. They test physical properties such as the melting point, the solubility and the electrical...

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.

In this chemistry activity, students answer 73 fill in the blanks and multiple choice questions on the structure of matter and properties of elements in the periodic table.

Blue-tinted water is added to unknown liquids that have been tinted yellow to find out how they interact. This is a memorable activity that is part of an investigation on the properties of liquids, which is part of a unit on the...

Fourth graders make observations of the reactions that happens between calcium carbonate and various liquids. During the experiment the students determine if there is a chemical change, a physical reaction, or no reaction when they mix...

For this scientific methods worksheet, high schoolers compare independent and dependent variables, hypothesis and theory, homogeneous and heterogeneous, and physical and chemical change. This worksheet has 17 short answer questions.

Pupils study the difference between chemical and physical weathering. They explore the effects of climate on the weathering process.

What's the matter? Gas, solid, liquid, or plasma. The presentation covers how to describe and identify matter, changes in matter, types of matter, measuring matter, particles of matter, Democritus, and John Dalton's Atomic Theory.

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....

An extremely thorough presentation walks new chemists through the basics of matter. There really isn't a unifying theme, however So many topics are covered: forces, elements, atomic structure, chemical properties, compounds, quarks,...

While this resource does not provide problems for chemistry learners to solve, it outlines skills that they should have and concepts that they should grasp. Topics include thermodynamics, periodicity, redox equilibria, transition metals,...

Students identify the physical and chemical properties and explore the differences.  In physical and chemical property instructional activity students test polymers for the differences between the physical and chemical properties,...

In May of 1981, the Winter Park Sinkhole in Florida first appeared and is now referred to as Lake Rose. Scholars learn about the causes of sinkholes through an inquiry project. Then, they analyze recent data and draw conclusions to...

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...

Students determine the base metals and surface metals in a penny. In this analysis of metals lesson plan, students determine the density of five pennies minted in different years. They use different chemicals such as hydrochloric acid,...

To guide learners through observations of chemical samples in the lab, this resource asks them to give all formulas and complete the attached data sheet.  There are multiple questions about categories of elements and general...

In this petroleum products activity, students are given the components of crude oil and they graph the various products found in a 50 gallon barrel. Students complete an activity to determine if they have collected cards that represent...

Fourth graders predict what happens in a teacher demonstration of a chemical change, before watching it. They observe the demonstration and list what the see on the board before determining which represent chemical change. Working at...

Students compare the weathering of materials. in this weathering lesson, students experiment with the chemical and physical weathering of different materials. Students use salt and water as an example of how weathering occurs.

Students identify the functions of packaging food and how the designs work.  In this food packaging lesson students identify the changes that occur in different types of materials. 

Students investigate how changes occur on the surface of the earth through erosion and glaciation. They observe what happens to salt and iron after they interact with water and vinegar, and analyze what occurs when water is sprinkled on...

Learners identify the physical and chemical properties of matter. They review the types of matter. Students list the four states of matter (Solid, Liquid, Gas and Plasma). They recognize and describe the different types of matter.

Students explore matter by conducting an in class demonstration. In this liquid mixture lesson, students identify the difference between a solution in which a solid dissolves into liquid, and a suspension where the solid doesn't dissolve...

If the area you live in is arid, or the preceding experiment in this unit didn't yield obvious results, use this one in place of it to help reveal where condensation comes from. The mini unit that this is part of a comprehensive...
