In this video adapted from the National Science Center, observe a demonstration to discover how helium gas is inert and hydrogen gas is reactive.

Students will be better able to discuss and describe what happens when air heats, and test their hypothesis with a hands-on demo

Engineers create and use new materials, as well as new combinations of existing materials to design innovative new products and technologies—all based upon the chemical and physical properties of given substances. In this activity, students act as materials engineers as they learn about and use chemical and physical properties including tessellated geometric designs and shape to build better smartphone cases. Guided by the steps of the engineering design process, they analyze various materials and substances for their properties, design/test/improve a prototype model, and create a dot plot of their prototype testing results.

This video segment adapted from A Science Odyssey looks at the invention of nylon.

What is chemistry? chemistry is the study of matter, so now the next question is what is matter?  In this unit we will discuss pure substances and mixtures, as well as physical and chemical properties.

This Introductory Chemistry textbook was developed by the Chemistry faculty at Montgomery College, and provided by Professor Patricia Takahara. The book is meant for students with very little or no background in chemistry. Concepts here are presented at a very basic level in order to provide the foundation for college-level general chemistry. This book is used in Introductory Chemistry, a non-credit, preparatory course at Montgomery College (Maryland).

This activity is a classroom lab in which students investigate and observe three types of balloons to help identify the states of matter and their properties.

In this interactive activity from ChemThink, learn how ionic bonds are formed and how an ionic bond structure is represented by its formula.

This activity is a mini-lab where students determine a procedure they might use to prove that air is matter.

This lab helps students to understand the density is state dependent and can change based on the state of the element.

In this video segment adapted from NOVA scienceNOW, follow scientists in their quest to understand how stable elements are made and how to create the elusive element 114.

How can you lift a heavy metal table using air? In this video segment adapted from ZOOM, cast members succeed in lifting a table using their own breath and a few plastic bags.

This 5th grade unit will take about 8 weeks, 25.5 hours to complete. Students plan and carry out an original investigation in which they observe the effect of different types of matter on the growth of plants. They create their own observable question with prompting such as: “What type of matter do you think will affect plants’ growth?” or “Do you think the amount of a particular type of matter will affect how the plant grows?” They observe their experiment over a period of seven days (or longer if time allows). At the conclusion of the investigation, students use their data to explain how plants convert matter (gas and liquid) into plant matter.

This video from KET traces the energy transformations that occur when coal is burned to produce electricity. Some of the mechanical processes are also described.

Two astronauts aboard the International Space Station (ISS) describe mass and weight and the differences between the two in this video from NASA’s Teaching From Space initiative.

The purpose of this lesson is to help students understand the relationship between the mass and the weight of an object. Students will study the properties of common materials and why airplanes use specific materials.

Students calculate the viscosity of various household fluids by measuring the amount of time it takes marble or steel balls to fall given distances through the liquids. They experience what viscosity means, and also practice using algebra and unit conversions.

This activity is a lab investigation where students gather data about the masses of various solid objects found in a classroom. The students graph their data, compare their data, and draw conclusions about what kinds of materials contain more matter than others.

This video segment adapted from Discovering Women profiles Fermilab physicist and Harvard professor Melissa Franklin.
