Chemistry is often defined as the science of matter and how it changes. This pathway introduces the composition of matter and the physical and chemical changes it can undergo.

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.

While this 10-question multiple choice quiz is published to accompany Glencoe's Physical Science textbook, it covers the basics of matter classification taught in any course. Written in standardized test style, learners can take the quiz, find out their score, and email their results to themselves or their instructor afterward.

Matter is all around us, so it's a good idea to know what it is, and why it matters. Learn about matter, its categories, and its subcategories with this interactive lesson.

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.

Through three lessons and their four associated activities, students are introduced to concepts related to mixtures and solutions. Students consider how mixtures and solutions and atoms and molecules can influence new technologies developed by engineers. To begin, students explore the fundamentals of atoms and their structures. The building blocks of matter (protons, electrons, neutrons) are covered in detail. The next lesson examines the properties of elements and the periodic table one method of organization for the elements. The concepts of physical and chemical properties are also reviewed. Finally, the last lesson introduces the properties of mixtures and solutions. A comparison of different mixtures and solutions, their properties and their separation qualities are explored.

This is the first instructional sequence in a teacher's guide built with the purpose of helping students build a deeper understanding of the Structures and Properties of Matter standard.Students have the opportunity to engage with interactive simulations, create poetry, drawing scientific diagrams, read complex text, develop evidence based explanations and design a model . The instructional sequence described in the lesson uses the 5 E learning model and includes a variety of online simulations, polls and model drawings.

In this interactive activity from ChemThink, learn about covalent molecules and how the VSEPR theory predicts the shapes of covalently-bonded molecules.

This is a guided inquiry investigation for students to determine the state of matter of a mystery material and to make potential real world applications/products for the mystery material.

Join a group of middle-school students on a visit to a laboratory at the Massachusetts Institute of Technology, where they experiment with "mystery mud" and learn about the relationships between magnetism, particle motion, and changes in the state of matter.

NREL’s Education team presents Matter by Andi Diehn. Join us as we read about matter and chemistry. After the story, we create animals made of gas, using balloons and other art supplies.

In this video adapted from NOVA scienceNOW, find out about the discovery of a new building material, the carbon nanotube, whose physical properties could theoretically enable the creation of a 22,000-mile elevator to space.

At this site read about Ernest Rutherford (1871-1937 CE), the scientist who was awarded the Nobel Prize in Chemistry, "for his investigations into the disintegration of the elements, and the chemistry of radioactive substances." This website includes both primary and secondary texts as well as resources for further reading and research.

Help Emilie keep the winery stable and sturdy. Join her to learn about different materials and their properties.

Set sail with Oleif, the Viking. Make his boat move by learning all about matter and particles.

This video segment adapted from FRONTLINE looks at nuclear fission as an energy source that can be used to generate electricity.
