In this heat worksheet, students determine the heat gained or lost when matter changes phases. Students review the energy flow through ecosystems by comparing trophic levels and food webs. This worksheet has 10 fill in the blank, 5 short...

Students explore the structure and property changes of water through videos and classroom discussion. They are introduced to atomic arrangement of solids by looking closely at carbon in different forms, such as graphite and diamond....

Students discuss and experiment with the phases of water.  In this phases of matter lesson plan, students recognize the different states of matter.  Students measure and record changes and understand when the state changes.

Young scholars explore the concept of healthy treats. In this healthy food lesson plan, students read ingredients and create healthy Halloween treats.  Young scholars also practice the skill of congruent shapes by drawing healthy...

Students determine the differences between the crystallization of igneous and metamorphic rocks. They examine both liquid state and solid state crystallization.

Students examine physical change with different temperature and solvents. In this elements and compounds lesson, students conduct experiments to discover what happens to the mass of a substance when is undergoes a physical change.

In this cold quiz worksheet, students complete a six question multiple choice on-line interactive quiz about cold places and cold weather.

Students review properties of matter and discuss how materials change when things are done to them. They observe how materials change as a reaction to temperature by following the procedure to make ice cream and recording the temperature...

Middle schoolers investigate various properties of ice including melting points and the effect of pressure on ice. They demonstrate how increased pressure lowers the melting point of ice and perform a simple experiment proving that water...

Pupils are read the story "Snowballs" and discuss what the conditions must be for it to snow. They make snowmen out of snow when it snows outside. They discover what happens to their snowmen when they take them inside.

Students discover the origin of the Great Ocean Conveyor. They participate in a demonstration showing how salinity and temperature affect water density. They also examine the new sea ice that forms every winter.

In this glaciers learning exercise, learners review terms associated with glaciers including esker, till, plucking, and outwash. This learning exercise has 14 true or false questions.

There are some amazing ways species evolve to survive. From large ears to sneezing salt, learners read about these interesting adaptations in an interactive lesson. Great to supplement an in-class lesson, it also works well as a remote...

In this half-life worksheet, students determine how much of the radioactive isotopes will remain after a certain amount of time. This worksheet has 11 problems to solve.

In this participial adjectives worksheet, students choose the correct way to complete the sentences with adjectives either ending in -ed or -ing. Students complete 16 sentences.

In this 3rd grade science worksheet, 3rd graders complete a total of 25 multiple choice questions related to grade 3 concepts. An answer key is given.

Students learn how science affects foods. In this chemical reactions lesson, students make two kinds of ice cream. They evaluate the different changes based on the ingredients.

Learners explore matter. They use a formula to measure the volume of matter.

In this winter facts learning exercise, students use provided links to find answer to 17 winter related questions. Two bonus questions are included.

Freezing temperature, the temperature at which a substance turns from liquid to solid, and melting temperature, the temperature at which a substance turns from a solid to a liquid, are characteristic physical properties. In this...

Percy Julian and Josef Pikl used the fact that melting point-the temperature at which a substance changes from a solid to a liquid-is a characteristic property of a substance to prove that the British chemist Robert Robinson could not...

Engage students in the study of the ocean and saltwater with these activities. Students will see that saltwater has different physical properties than freshwater - mainly density. This lesson can serve as a springboard into other...

A page from the University of Maryland Physics Lecture Demonstration Facility. Provides directions for a teacher demonstration of the effect of an ionic solute upon the freezing point of water. Shows apparatus and set-up; provides...

In this activity, Students can use an EasyTemp temperature probe to determine the normal melting temperature of ice. They will then study how the addition of salt to the melting ice affects its melting temperature. They will finally...
