Fourth graders study evaporation and condensation as parts of the water cycle. First they determine the similarities and differences between a cup of water and an ice cube before measuring the volume of ice before melting it, and...

Fourth graders determine what is meant by a physical change, and they demonstrate how they can make physical changes. They complete activities at stations that entail changes in color, size, texture, hardness, or state of matter. Using...

This is one in several lessons that explore the relationship between temperature and phase changes of water. After some discussion, elementary physical scientists place wet paper toweling on a hot and a room-temperature water bag...

Young scientists get to the heart of the matter as they complete this worksheet on the properties of solids, liquids, and gases.

Students learn about matter and energy. In this science lesson plan, students gain an understanding of the properties of matter and energy as they discover that some things float, some things dissolve in water and discuss that energy can...

In this chemistry activity, students answer 73 fill in the blanks and multiple choice questions on the structure of matter and properties of elements in the periodic table.

What's the matter? Gas, solid, liquid, or plasma. The presentation covers how to describe and identify matter, changes in matter, types of matter, measuring matter, particles of matter, Democritus, and John Dalton's Atomic Theory.

Students solve a mystery using evidence gathered during a science investigation.  In this physical changes lesson, students analyze a note written in marker to determine the physical changes the ink from the pen underwent....

Pair earth scientists up to use an amazing online arctic portal mapping tool and Google Earth to analyze permafrost changes. They compare changes to data on atmospheric concentrations of methane to see if there is a correlation. Then...

Here is part two of a two-part lesson in which scholars investigate the changing states of water—liquid, solid, and gas—and how energy from heat changes its molecules. With grand conversation, two demonstrations, and one hands-on...

Here is part one of a two-part lesson in which scholars investigate the changing states of water—liquid, solid, and gas. With grand conversation and up to three demonstrations, learners make predictions about what they think will happen...

Students observe physical change of melting by observing substance in original state, melting substance, allowing substance to return to original temperature, determining if substance retained its original properties, and recording results.

Students participate in experiments to visualize the differences between chemical and physical changes. They attempt to detect the five characteristics of a chemical change.

Middle schoolers explore heat energy and how it is used to change the phase of matter, and discover that temperature does not increase or decrease until the phase change is complete. This extremely well-written plan is packed with great...

Does gold really boil? Learn what temperature gold boils at and more using an animated activity about the properties of matter. Scientists learn about the properties of matter including examples of physical properties, the effect changes...

Once I told a chemistry joke, but there was no reaction. Get young chemists involved in changes and reactions with a presentation that begins with physical and chemical changes and chemical reactions. It moves on to chemical...

Scientists have been studying exothermic reactions before they were cool. The lesson begins with a discussion and a demonstration of heat curves. Scholars then determine the heat of fusion of ice and the heat needed to...

Pupils explore matter by conducting an in-class experiment. They experiment with water's various forms by melting and freezing water, identifying its new shape. These observations are recorded to supplement later discussion. They also...

Pupils explore the states of matter. They discuss the different phrases of matter and categorize everyday substances as solids, liquids, or gases. Students explore the relationship between the phases on an atomic level and the role of...

In this properties of matter worksheet, students answer 6 questions related to matter. They classify and categorize given statements as chemical or physical properties, they identify chemical and physical changes and they find the...

Teaching is a balancing act! Keep things on an even keel with a comprehensive equilibrium lesson plan. The resource covers reversible and irreversible reactions, Le Chatelier's Principle, and the industrial applications of equilibrium...

In 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...

Display the arrangement of molecules in solids, liquids, and gases. Demonstrate how the addition of heat energy results in greater molecular motion and therefore a change of phase. Give examples of heat conductors and insulators, and...

Do charged and neutral particles behave differently as they undergo phase changes? Science sleuths examine two types of attractive forces using an informative interactive. Pupils can vary the amount of Van der Waals attraction present...
