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...

Students investigate buoyancy. In this buoyancy lesson, students apply the Archimedes Principle of Buoyancy to the experiment conducted in class to determine how battleships float.

Eighth graders practice using correct vocabulary and apply content knowledge related to phases of matter when answering questions about situations or observations from everyday life.

Students explore the states of matter. In this physical science lesson, students observe what happens to water when it freezes and record observations. Students then observe ice when it melts and record observations.

Science rocks! Explore three types of rocks and the rock cycle with an igneous rocks experiment. Pupils discuss textures, composition, and learn how melts are formed from the Earth's crust. They weigh materials using a scientific scale...

Students are introduced to the processes of evaporation and condensation as they observe physical changes in water. They observe how matter changes from a solid to a liquid state. Students are explained that steam is water in its gaseous...

Students investigate moles and Avogadro's hypothesis. In this moles lesson plan, students complete a worksheet by finding the volume of 1 mole of each substance given its density and they find the number of molecules, the formula, the...

Students 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 test various liquids and identify as acids or bases. In this chemistry and pH lesson, the students use purple cabbage indicator to test a variety of teacher-provided substances, then bring in liquids from home to test acidity....

Love is in the air? Wrong — nitrogen, oxygen, and carbon dioxide are in the air. The final lesson in the series of five covers the impact of temperature on gases. Scholars view a demonstration of gas as a type of matter before performing...

Eighth graders biew each volume container and discuss where they have seen them in their home, and how they have seen them used. They explore the different names of volume sizes and their equivalents towards one another. Students...

Young scholars compare and contrast conditions on Mars to those on our own planet, specifically, their local or regional environments. The physical characteristics, the atmosphere, and other astronomical data is considered.

Students examine a density demonstration involving ice cubes and beakers of water and alcohol. After observing how one ice cube floats in water and sinks in alcohol, they determine which mixture of the two would suspend the ice cube in...

Students determine the force of a helium balloon that allows it to rise a specific distance.  In this helium lesson students calculate the amount of paper needed to construct a weight and determine the density of a piece of...

Students investigate crude oil. In this crude oil lesson, students investigate fractional distillation and use this technique to separate two liquids.

Students investigate the scientific concept of why some objects float when put in a liquid solution. They apply the laws of motion and force while conducting classroom activities. Students also take notes and answer target questions to...

Students define density and explain how to determine the density of an object. Students participate in a demonstration that shows the differences in the densities of different liquids and how they affect the liquid's physical properties.

Students participate in a demonstration to test the different densities of plastics, and suggest a method that plastic waste can be separated and collected.

Pupils design an experiment to determine which liquid is water. In this chemistry lesson, students perform the experiment as outlined in their design. They record observation and formulate conclusion.

Twelfth graders work in teams to design a method of recycled plastics purification by flotation. They base their design on the concept that different kinds of plastics have different densities and keep overall costs and purification time...

Students test the conductivity of selected liquids and solids. They test the circuit by touching the two free ends of the wires together and add salt little by little recording the data after each addition. Finally, students predict...

We have formulas for finding the volume of geometric shapes, but what if the shape is irregular? Lesson describes how to find volume through water displacement. After a demonstration, scholars practice in small groups. Then analysis...

Scholars find Earth won't support humans much longer and need to identify a planet with water to inhabit. They test four unknown samples and determine which is the closest to water. Then they explain and defend their results.

A fascinating and engaging lesson on the properties of water awaits you. In it, learners engage in four activities that are designed to teach about the properties of water. This exciting plan has worksheets embedded in it which make the...
