In this physical world instructional activity, students review concepts relating to the chemical and physical properties of matter, density of matter, and if matter is a solid, liquid, or gas. This instructional activity has 9 terms in a...

Does the size of a sample change the physical properties of that substance? It turns out it can! Young scientists combine physics and chemistry to synthesize CdSe quantum dots and record their color properties. Learners should...

Pupils conduct a mock trial focusing on environmental accountability of industrialized nations. As an example, they evaluate evidence provided on carbon dioxide emissions. They participate in a mock trial of industrialized nations by the...

Who can grow the best crystals? Challenge class members to develop strategies for enhancing growth in the crystals. Through a lab investigation, learners study the properties of crystals and test the effectiveness of different...

We all know limestone weathers, but what affects the rate of weathering? Young scientists investigate the physical and chemical weathering of limestone (chalk) through experimentation. First, they conduct trials with different-size...

We have all heard the debate about teaching both theories, but an innovative lesson takes the discussion to a new level. Scholars research and debate Newton's Law of Gravitation versus Einstein's General Theory of...

Students participate in a science experiment to understand that matter takes up space.  In this matter lesson, students experiment with solids, liquids and gases to recognize that matter is everywhere. Students make observations and...

Whether you're battling the flu or trying to warm up on a chilly day, your body's ability to react to temperature change is fascinating! Anatomy scholars discover the fantastic feedback loops that control body temperature in a rigorous...

Crystals are more than meets the eye! Can learners tell them apart simply by observation? As they examine five samples with a magnifier, they find that appearance alone is not enough. This serves as an introduction to a mini unit on...

Students examine and discuss how atoms change from solid to liquid to gas. They inflate a balloon by melting ice that converts to steam, and discuss the results.

Sixth graders, in groups, observe the difference between physical and chemical changes and create a collage of pictures to show the difference.

Eighth graders, in groups, explain the difference between physical and chemical changes.

Second graders investigate how objects can be described, classified and compared by their composition. They recognize that the same material can exist in different states. Students verify that things can be done to materials to change...

In this matter activity, students identify words and match them to their definition. Students identify words dealing with matter, its physical changes, and the effect of heating and cooling matter. This activity contains nine matching...

Third graders conduct experiments in matter to create chemical changes resulting in gases. By mixing solids and liquids, they create a chemical reaction and capture the gas in balloons. After observing the balloons fill with carbon...

Let Einstein's work shine the way. Pupils read about Einstein's iconic equation, E=mc^2, using a remote learning resource and see how ideas from other scientists such as Kepner, Curie, Galilei, and Newton led to its discovery. They...

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...

Students investigate and explore the three states of matter. They read and discuss the NASA article "The Engine That Does More," identify examples of each state of matter, and as a class complete a section of two worksheets. They...

Students study matter. In this science lesson plan, students examine the relationships among gravity, weight, and mass, the metric measurement of distance and volume, and density and its application to physical properties.

Students study the difference between physical and chemical properties. They also discuss changes in matter, known as physical and chemical changes. They observe and discuss several demonstrations of both physical and chemical changes

Students make ice cream as a result of viewing changes of states of matter. In this matter lesson plan, students learn how heating and cooling can effect a state of matter to change.

Students analyze the causes of corrosion. In this chemistry lesson, students investigate what is necessary to cause chemical changes in matter. Students discover the causes of rust and tooth decay.

A review of a full unit on energy and matter, this slide show starts with basic definitions of states of matter and their mass. It then develops the ideas of the forces that that matter can exert. Details about bonding within matter and...

Chemical and physical properties give compounds an identity. Learners use the identity of a compound to predict what it is. By performing different tests like solubility, flame, heat, and reactions, individuals attempt to identify an...
