For this scale worksheet, students use the SI system to compare the sizes of some of the smallest and largest organisms on Earth. This worksheet has 7 problems to solve.

In this thermochemistry worksheet, students indicate whether the given processes are endothermic or exothermic reactions. Kids complete the phase change diagram as well as define a given set of vocabulary words. Students calculate mass...

Students explain scientists' ideas about the structure of the atom over the last century. They develop a pictorial history of the changing ideas about the atom and write a caption describing the scientific thinking behind the model.

Students explore matter through the concept of displacement. They perforrm an inquiry experiment with a glass, paper and a bucket to demonstrate that gases take up space.

Young scholars examine the physical properties of matter. They identify and classify a variety of objects based on their physical properties.

Third graders investigate the three states of matter and the properties of materials as they undergo physical changes. They identify examples of each type of matter, role-play atoms in solids, liquids, and gases, and conduct an...

Second graders investigate the properties of solids and discover how to classify them. Using rulers, they measure various solids on display. In groups, they play an identification game where one students names a location, such as the...

Learners use indicator paper to determine if substances are acidic, basic, or neutral. They test for Ph levels in them. They investigate the effect of oxygen on darkening fruit cut and exposed to the air. They observe vitamin C as an...

Physical science learners define matter, explain the law of conservation of matter, and identify compounds according to their state on this twenty-question test. Most appropriate for the introductory physical science class, this resource...

Students examine the processes of melting and freezing.  For this matter lesson students complete a lab in groups, discuss what they learned and view a teacher demonstration. 

Ninth graders explain how a scanning tunneling microscope works. In this chemistry lesson, 9th graders construct atomic models and simulate how their images appear under the STM. They discuss the limitations of their atomic model.

Students complete presentations of their understanding of the concept of matter in many different forms. In this matter lesson plan, students use whatever multiple intelligence they feel strongest in to present their presentation.

In this limiting behavior of equations worksheet, students use the Klien and Nishima formula to find the limit for large X which is the ratio of energy carried by a photon compared to the rest mass energy of an electron.

In this Bill Nye packet, 5th graders focus on the phases of matter.  Students complete a chart of what is already known and what has been learned as well as 6 short answer, 7 true/false, and 3 multiplie choice questions about the...

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

Students explore snow. In this forms of water lesson, students read a story about snow, identify the types of snow found in Alaska, and learn Inuit words for snow. The lesson calls for an Intuit Elder to visit the classroom as a guest...

Students study the liquid and solid states of water. In this water states instructional activity, students complete three experiments to study water as it cycles from a liquid state to a solid state and back. Students finish with a Venn...

Students conduct an experiment. In this forms of water lesson, students observe ice to see what changes take place and then write in their journal about what they observed.

Young scholars explore the states of matter. In this physical science lesson plan, students observe what happens to water when it freezes and record observations. Young scholars then observe ice when it melts and record observations.

Students investigate the states of matter. In this physics lesson, students use water and ice to demonstrate the characteristics of a solid and liquid. Students record their observations as the state of the water changes.

Students explore the water cycle. In this water cycle lesson, students complete a hands-on activity that replicates the water cycle. Students record their observations.

Students investigate water in its solid and liquid form. In this states of matter lesson, students experiment to see what happens as water goes from a solid, ice, to a liquid, water, and back again. They write about and illustrate the...

In this online interactive anatomy crossword puzzle activity, students use the 8 clues to find the appropriate answers to complete the word puzzle.

For this tools worksheet, students read about the tools used during the Stone Age and how the process of smelting lead to a great change in tool making. Then students complete 3 short answer questions.
