Physical and Chemical Change
Students study the differences between physical and chemical changes. In this physical and chemical lesson students complete several labs to help them to see the differences between these changes.
Curated OER
Observations & Chemical Reactions
Students conduct a series of experiments in which they explore chemical reactions. They detect chemical changes by observing how physical properties change when two different chemicals are combined. They list and describe the reactants...

Understanding Chemical and Physical Reactions
For this chemical and physical reactions worksheet, students read a 2 page science article, answer 10 statements as true or false, give 2 ways a chemical reaction is different from a physical reaction, answer 1 short answer question and...
Curated OER
Chemical Bonding
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...

Chemical Composition of American Coins
High schoolers investigate the chemical composition of pennies dated 1983 or later. In this chemical composition of American coins lesson plan, students scratch the surface of the penny to expose the zinc core. They put the penny in...
Curated OER
Dust in the Wind; Chemicals in the Water
Students explore mechanical and chemical weathering at stations. They articulate some mechanisms of chemical and mechanical weathering through exploration in a lab. Students stations describe how chemical weathering differs from...
Curated OER
Heat, Temperature, and Transfer
Physical science scholars discover an array of heat sources. They experiment to connect radiation to heat. They begin to understand thermal equilibrium. Then, they test to see if mass affects the rate of temperature change. Choose a few,...
Curated OER
Physical and Chemical Changes
In this changes in matter worksheet, students draw a picture that shows physical and chemical changes. This worksheet has 7 fill in the blank questions.
Curated OER
Scientific Method
For this scientific methods worksheet, students compare independent and dependent variables, hypothesis and theory, homogeneous and heterogeneous, and physical and chemical change. This worksheet has 17 short answer questions.
Curated OER
Physical and Chemical Changes
Students differentiate physical and chemical changes. In this chemistry lesson, students identify five indicators that a chemical change took place. They complete a reflection journal at the end of the activity.
Curated OER
Physical and Chemical Changes
Eighth graders distinguish between physical and chemical change. For this chemistry lesson, 8th graders observe a series of demonstrations showing physical and chemical changes. They identify the signs that a chemical reaction took place.

Up and Atom
"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...
Curated OER
Physical vs. Chemical Change Lab
Students recognize both a physical and chemical change in different substances. They determine which particles actually changed into different substances, and explain if it represented a physical or a chemical change.

The Law of Conservation of Matter
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...

Atomic Theory
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,...
Curated OER
Physical and Chemical Changes
In this physical and chemical changes worksheet, students will read 4 different examples of a physical or chemical change and will write in the effect of each of these changes.
Curated OER
Chemical or Physical?
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...
Curated OER
Stomach Chemistry
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.
