In this solutions learning exercise, high schoolers answer 18 questions about solutions, saturation of solutions, solvents and solubility.

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.

Students explore latent heat and how it relates to clouds in the atmosphere.  In this earth science lesson students investigate how clouds are formed. Students examine clouds and the water cycle.

In this matter worksheet, students complete a graphic organizer by describing the properties of matter, the changes of matter, and how matter can form mixtures.

Anytime you make concepts clear with role playing or hands-on experience, it's a win for the whole class. Ping-Pong balls are used to represent carbon in a carbon cycle role-play activity. In small groups, children first discuss what...

Fifth graders explore the phases of matter, make observations of matter, the physical and chemical properties of matter, solutions and mixtures, formation of molecules and atoms and molecules all through hands on activities.

In this matter worksheet, learners compare and contrast chemical and physical properties and explain the relationship between a pure substance and a mixture. Students review the properties of metals and nonmetals. This worksheet has 1...

Students examine how humans perceive color. In this refracted light lesson, students explore the different ways color is seen by the human eye. Students will use colored lights and colored paper and solid objects to make additive color...

Students are introduced to the basic parts of rockets and the physical forces at work in the flight of rockets. They build and launch a model rocket and discuss the challenges of launching a real rocket.

In this separating solids experiment worksheet, students follow the procedures to find what physical properties could be used to separate a mixture of pepper, salt, sand and iron filings.

In this chemistry worksheet, students investigate through experimentation the solidifying behavior of some edible fat mixtures by determining their cooling curves. Then they data-log equipment to obtain a large number of temperature...

Learners isolate three species of bacteria using the plate streak method, implement sterile microbiology techniques, and produce pure cultures of each microorganism at the end of this exercise. They write a descriptive paragraph for each...

In this water worksheet, students review the properties of water including the density, boiling point, and evaporation. Students define mixture, solute, and solvent. This worksheet has 22 short answer questions.

Students complete lessons on a butterfly life cycle, moon phases, hot water, and shadows. In this science lesson plan, students complete activities where they read books, look at demonstrations, and complete experiments.

Young scholars mix two different solutions to become more familiar with molecules and polymers. In this chemistry instructional activity, students decide whether or not the reaction between two solutions is chemical or physical. Young...

Learners explore the concept of photosynthesis. They describe the light and light independent reactions of photosynthesis. Students relate physical plant characteristics to their functions. They distinguish between C3, C4, and CAM plants...

Young scholars explore permafrost.  In this 3 states of matter lesson, students identify characteristics of solids and liquids.  Young scholars observe water and soil melting and freezing at various temperatures.  Students...

Student examine the physical changes of matter and are able to describe them. They make ice cream in plastic bags to observe the changes in matter. They describe and record the changes in the ice cream mixture as it freezes.

Students experiment with plastics.  In this what is plastic lesson, students make a simple polymer and discuss recycling.  Students identify various types of plastics. 

In this science word search activity, students identify and locate words in a puzzle that relate to particle theory of matter. There are 24 words to locate in the puzzle and spell correctly.

In this science worksheet, students find the terms that are related to the concept of the ocean salt and sand. The answers are found by clicking the link at the bottom of the page.

Students investigate how information about the atom has been determined. In this atomic structure activity, students draw what they think an atom looks like. They conduct Internet research about the types of atomic models and how...

Students identify the different components of a given sample using chromatography. In this chemistry lesson, students compare paper and column chromatography. They collect data and construct data tables.

In this science worksheet, learners examine the physical changes associated with the change of temperature and mixtures. The answers are included.
