In this matter worksheet, high schoolers compare and contrast chemical and physical properties and explain the relationship between a pure substance and a mixture. Students review the properties of metals and nonmetals. This worksheet...

Students classify items according to their physical properties. In this chemistry activity, students define what matter is in their own words. They use the matter diagram to organize different substances.

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...

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...

Lights, shadows, action, and inquiry await your artistic scientists. They explore the way light travels, absorbs, reflects, and transmits through shadow play. They create folktale-inspired shadow puppets, explore the science of light,...

There's no such thing as the perfect crime! Your class of sleuths are ready to investigate the trace evidence at a crime scene and compare it to a list of suspects. They use their investigative skills to record physical properties of the...

Section 9 of the 12 linked Saxon Math sections introduces the young algebrist to graphing periodic functions, creating graphs from quadratic roots, working with inequalities, and rational equations. Common among all the lessons is the...

Ah, caffeine! What would some of us do without it? Teach your high school chemistry class the concept of sublimation as they complete a hands-on experiment to visualize the changes caffeine undergoes during heating and cooling....

Students develop their own techniques for drawing a small sample of solutions into a straw. They hypothesize ways to increase the density of water, and discuss how salt-free rainwater tends to float on top of salty seawater.

Students determine the base metals and surface metals in a penny. In this analysis of metals lesson plan, students determine the density of five pennies minted in different years. They use different chemicals such as hydrochloric acid,...

Young geologists discover the important role that rocks and minerals play in our everyday lives through this series of hands-on activities. Starting off with a lesson that defines the difference between plants, animals, and...

Solidify understanding of the properties of crystals by crushing them to compare hardness. After some class discussion, a procedure is planned, and then small groups go about making observations as they crush five different crystal...

Does the depth of a pond matter to the waves created when rain is falling? Many people assume the answer is no, but interestingly, it does matter. Pupils explore this concept and other variables related to wave behavior through a...

In this science worksheet, students read passages and derive the meaning from them to answer three key questions related to mass and weight.

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....

In this matter worksheet, students complete a graphic organizer by describing the properties of matter, the changes of matter, and how matter can form mixtures.

First graders discover the properties of matter through hands-on experiences, 1st graders discover how to protect their Freeze Pop from melting.

Students experiment to find which liquids are more dense.  In this density and mass lesson, students predict and then test objects to observe and measure their density. students observe which items sink and float. Students complete...

Young scholars experiment with balloons, soda water and raisins to find out about the states of matter.  In this solids, liquids and gases instructional activity, students complete a group activity with balloons to recognize the...

Students explore matter by conducting an in class demonstration. In this liquid mixture lesson, students identify the difference between a solution in which a solid dissolves into liquid, and a suspension where the solid doesn't dissolve...

Fifth graders identify, through experimentation, what properties of substance are, determine what variables tested will be, identify constants and variables of experiment, conduct experiment to conclusion with measurable, recorded...

Viewers define viscosity as resistance to flowing and they compare the viscosity of different liquids. Instructions are not provided, but junior scientists design an experiment to test different liquids and order them from low to...

Ninth graders conduct research on the subject of sea water. They use a variety of resources to obtain information. There are helpful resource links listed in the lesson. In conjunction with the research students make inquiry of the...

Is assembling the periodic table as simple as Tetris? Scholars arrange colored cards into a logical order and then make connections to the arrangement of the periodic table. Hands-on activities include adding trend arrows and analyzing...
