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...

Assist your middle school class with one of the most inclusive weathering and erosion labs available. Individuals use sugar cubes and alka-seltzer to demonstrate the process of physical and chemical weathering. They sketch results...

Climate models mathematically represent the interactions of the atmosphere, oceans, land, sun, surface, and ice. Part two in the series of four lessons looks at the role greenhouse gases play in keeping Earth warm and has participants...

Sometimes, despite the best laid plans, the unexpected will occur. Learners witness this firsthand as they carefully design an experiment to determine the time needed for ice to melt in salt water or pure water. They uncover facts not...

Use STEM activities within the class to provide connections to concepts. The resource includes activities that range from working with buoyancy to building rockets and launching them. Other activities involve the engineering design...

Students are able to give specific examples of what to do and what not to do during given safety situations, and classify materials as metals, polymers, ceramics/glass, or composites. They are able to distinguish between chemical and...

Some say cooking is an art—and a science! Scholars scope out the savory subject of molecular gastronomy with a series of related activities. The teacher's guide contains printable worksheets and helpful tips for implementing the lesson.

In this matter and change worksheet, students answer 24 questions on topics such as elements, compounds, mixtures and chemical reactions. Students answer questions about the properties of matter such as their physical state and shape. In...

Designing the right package — it's more than a pretty picture. Challenge small groups to design a food package. They must consider the type of food they are packaging and the package's ability to control the physical and...

RJ argues that playing the video game, Super Duo Breaker and Whoosh, is a good way to study for a quiz on weathering and erosion. The game character Mr. Breaker breaks things down and the character Mr. Whoosh carries them away in the...

If you are willing to sort through this outline and overlook the portions relating to inaccessible videos, you will find a wealth of support for your introductory chemistry unit. Narrative is presented to help you help learners navigate...

In this physical and chemical change worksheet, students calculate the entropy change involved in different chemical changes. This worksheet has 4 problems to solve.

Topping this worksheet is a comprehensive collection of notes about phase changes. The phase change graph is displayed, along with formulas for the gas laws, and information relating energy to change of phase. After reviewing these...

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

Young scientists form teams and compete by providing questions for words and phrases related to science topics arranged in a Jeopardy quiz show game format. The categories include matter, measurement, vocabulary, and chemical or physical...

Fourth graders investigate chemical changes in everyday life settings, such as cooking. They investigate leavening which is one of the classic chemical changes that people experience. Pupils observe leavening in biscuits with the...

Students investigate the chemical composition of pennies dated 1983 or later. In this chemical composition of American coins lesson plan, students scratch the surface of the penny to expose the zinc core. They put the penny in...

Students compare the carbon dioxide content of four different samples. In this chemistry lesson, students research the causes of global warming. They explain how humans contribute to rising global temperature.

Is your class in the dark about photosynthesis? Shed some sunlight on an important biological process with a thoughtful activity. After answering questions to help determine their level of knowledge, learners work with chemical equations...

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

Fifth graders conduct an experiment.  In this changing matter lesson, 5th graders receive a cup of crystals, record their observations, add water to the crystals and record new observations. Students then discuss the differences...

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...

Fifth graders investigate chemical reactions. In this physical science lesson, 5th graders make dry ice root beer and identify the type of change that occurs to the root beer mixture.

Students investigate osmosis and diffusion in a liquid environment. In this osmosis lesson plan, students use dialysis tubing made into bags and filled with 3 different solutions. They observe the movement of water molecules into higher...
