Curated OER
2009 U. S. National Chemistry Olympiad - Local Section Exam
Here is a copy of a past national challenge exam that you can use in your general chemistry course as a unit or semester review. Sixty multiple-choice questions query learners on properties of matter, stoichiometry, reactions, and...
Curated OER
Fluid Thinking About Liquids and Solids
Second graders examine the physical characteristics of the different states of matter. In this chemistry lesson, 2nd graders observe how matter changes from one phase to another. They classify substances according to its type of matter.
Curated OER
Chemistry
As the title implies, this PowerPoint defines and illustrates the basic terms involved with describing matter. Phases of matter, atomic structure, and the different categories of compounds are included. Slides are simple and uncluttered....
Curated OER
States of Matter Mini-Unit
Middle schoolers identify he phases of matter (solid, liquid, gas), and why they take place. They comprehend what a physical change is and what a chemical change is. Students know the difference between a Mixture and a Solution.
Curated OER
Solid, Liquid, and Gas
Delve into the differences among solids, liquids, and gases with this PowerPoint. It is both applicable and attractive. Large, colorful diagrams display the molecular arrangement of each state of matter and their properties are arranged...

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...
Curated OER
It's The States of Matter
Students investigate the properties of solids, liquids and gases. For this states of matter lesson plan, students observe dry ice and its characteristics. They calculate the density of dry ice and observe the sublimation of the dry ice...
Curated OER
Physical and Chemical Properties of Matter
Students 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.
Curated OER
Mixing It Up!
Third graders identify the different states of matter. In this science lesson, 3rd graders describe the different components of solutions and mixtures. They create emulsions, foams and suspensions in the lab.
Curated OER
Be a Scientist: A Kindergarten Unit
Students conduct observations using their five senses. In this science lesson, students describe different states of matter. They investigate the factors affecting mold growth.
Curated OER
What's the Matter?
First graders identify solids, liquids, and gases. In this matter lesson, the teacher guides students through numerous demonstrations as they determine the properties of solids, liquids, and gases and classify things as each. As the...
Curated OER
Dark Matter In The Universe
Students investigate the concept of dark matter and how it occurs in the universe. They conduct research using a variety of resources. Students use the information by reading at least two articles about dark matter. They also generate...

Chemistry: States of Matter Quiz
For this chemistry worksheet, 11th graders take a states of matter quiz by matching 10 terms to their definitions, decide if 10 statements are true or false, and answer 2 fill in the blank questions.
Curated OER
State Change
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,...
Curated OER
Phase Changes
In this phase change worksheet, students read about the particles in substances that speed up and slow down for substances to change phases. They answer eight questions about phase changes, the states of matter and how changing...

Condensation
It's time to break the ice! If you are doing all of the lessons in the unit, children have already seen that increasing heat increases the rate of evaporation, but is the opposite true? Does decreasing temperature cause more condensation...
Curated OER
What's Matter?
Middle schoolers explore the definition of matter. In exploring matter lesson plan students get into groups and navigate the Internet to answer questions.
Curated OER
It's a Gas! Or is it?
Oceanography enthusiasts are given a series of thought experiments to consider in order to relate the solubility of gases and solids to underwater volcanoes. It is not particularly engaging to perform these thought experiments. Choose...
Curated OER
The Same, But Different
Third graders examine the phase change between solids and liquids and determine it to be a physical change. Ice is the perfect item to use to demonstrate this phase change. Pupils experiment with measuring and weighing solid ice and the...
Curated OER
Thermochemistry
In this thermochemistry worksheet, students indicate whether the given processes are endothermic or exothermic reactions. Students complete the phase change diagram as well as define a given set of vocabulary words. Students calculate...
Curated OER
What's the Matter? Where Did it Go?
Eighth graders analyze questions posted on a large poster in the room and work in groups to record their response to the question on paper, rotating to the next question after two minutes have passed. They review the characteristics of...
Baylor College
What Is the Water Cycle?
Small groups place sand and ice in a covered box, place the box in the sunlight, then observe as evaporation, condensation, and precipitation occur. These models serve as miniature water cycles and demonstrations of the three phases of...
Curated OER
Phases of Matter
Students describe the motion of solids, liquids and gases. In this chemistry lesson, students describe how temperature affect motion of the particles. They determine the physical properties of each phase.
