Demonstrate the particle theory of matter to high school scientists with an engaging experiment that allows them to visually see the results as substances change from one state to another. The class concludes with a discussion about how...

Take a "conservative" approach to planning your next unit on mass and matter! What better way to answer "But where did the gas go?" than with a lab designed to promote good report writing, research skills, and detailed observation....

Can your class tell the difference between a burette and a pipette? Develop their lab apparatus knowledge using a series of puzzles. The online activity associates the name, image, and sizes of burettes, pipettes, volumetric flasks, and...

It's assessment time! Determine your young mathematicians' understanding of elapsed time with this brief, five-question quiz.

In this spherical tanks and fuel level worksheet, students are given a diagram showing the effects of gravity or acceleration on the level of fuel in a spherical tank. Students solve 3 problems including finding the general formula for...

Students explore the three states of matter. For this physics lesson, students are shown examples of solids, liquids, and gases. Students make cookies and identify the three states of matter during the baking process.

Learners determine the heat of fusion of ice. In this heat of fusion lesson plan, students use a calorimeter to measure the molar heat of fusion of ice. Learners determine the heat required to melt one mole of ice using hot water and ice...

Learners determine the density of 1 drop of water. In this determining density lesson plan, students determine the mass and volume of a drop of water in the lab using appropriate lab techniques and calculate the density of a drop of water.

Students investigate density and salinity of water. In this density and salinity lesson plan, students find the density of objects and liquids and show the relationship between the salinity and density of water. Students add salt to...

In this planet models learning exercise, students use the radius of a given planet and its mass to answer questions using a model of a planet with a given radius. They determine the volume of the planet's inner core, the volume of its...

Learners identify the physical and chemical properties of matter. They review the types of matter. Students list the four states of matter (Solid, Liquid, Gas and Plasma). They recognize and describe the different types of matter.

Students explore the concept of density. In this density lesson plan, students determine the density of a crown and a sample of clay. They hypothesize about the densities of 4 liquids they are given including molasses, cooking oil, a red...

Learners investigate the gas laws and how they apply to changes in gases. In this gas laws lesson, students use Boyle's Law and Charles' law to show the relationships between pressure and volume and volume and temperature of gases.

Students investigate the properties of matter. In this properties of matter lesson, students observe containers of different metals and discuss their properties including density. Students find the density of an unknown metal and of...

Students participate in experiments at five stations to practice measurement. In this measuring lesson, students are presented different produce and objects and must measure with an appropriate tool. Students use metric and customary...

In this pressure worksheet, students read about Dalton's Law of Partial Pressure, about vapor pressure and about collecting gases over water. They answer 6 questions using the concepts of Dalton's Law of Partial Pressure and they solve 4...

In this absolute zero worksheet, students experiment with a closed-end syringe and a ice bath and boiling water. They record volumes of gases in the syringe as well as temperatures of the water and they plot their experimental data. They...

In this classification of matter learning exercise, students answer 15 questions about solids, liquids and gases, types of mixtures and compounds vs. elements. They also answer 2 questions about measurement and 1 question about a biome.

Stir chocolate drink mix into hot and cold water to see if there is a difference in how quickly it dissolves. Number three in a six-lesson unit on dissolving, this installment investigates the effect of temperature. If you consult the...

Watch the damage from a forest fire in this interactive simulation activity that challenges learners to estimate the burn area using different approaches. Learners are given a worksheet to track the different burn patterns and practice...

Learners explore the solar system. In this planets lesson, students learn about the other planets in the solar system. They watch a video clip from National Geographic on the solar system, compare and contrast the planets and create a...

Students design a simple boat and predict how much weight it can carry. They should also discover why objects float or sink and how this can be determined experimentally. A great lesson on buoyancy!

Students consider what happens to herbicides or insecticides that are used in agricultural practices, especially herbicides that are used to control noxious weeds. They become acquaint with a chemical assessment method known as...

Students explore tessellations. In this shapes and geometry lesson, students describe the attributes of many of the shapes displayed on an Elmo. Students create examples of tessellations using pattern blocks.
