Whoa! What just happened? That's right, change is everywhere. But what exactly is changing? Middle school science sleuths get to the bottom of the changes matter can experience. Through simple demonstrations, engaging videos, and an...

The more things change, the more they stay the same. This unit includes seven lessons starting with physical change and moving through to chemical change. Conservation of matter is explained clearly with multiple hands-on activities and...

Now you see it, now you don't. Our moon seems to pull a disappearing act from time to time—but why? Take your seventh grade scientists above and beyond to discover the truth about the moon and the role it plays in Earth's little...

Adolescence and teenage years are very difficult in terms of emotions, primarily due to the amount of change going on in growing teens' lives. Guide middle schoolers through disruptive changes and transitions with a set of activities...

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....

Building off young chemists' knowledge of the states of matter, kinetic molecular theory is the focus of the unit. Eight days of lessons including multiple demonstrations, one lab experiment, directed instruction, and worksheets,...

Even though they may not be tested on standardized assessments, social skills are vital for students to develop during their years in school. Through a series of discussions, activities, and role-playing exercises,...

Astronomy is literally over your head, but this lesson will explain how we study it. Young scientists make telescopes, calculate and compare the light gathering power of lenses, and simulate detection of infared radiation....

Students explore human growth and development as they participate in class activities, reading and discussion. Worksheet and handouts are included in the lesson.

By the end of this section, you will be able to interpret a phase diagram; state Dalton's law; identify and describe the triple point of a gas from its phase diagram; and describe the state of equilibrium between a liquid and a gas, a...

This lesson will introduce a phase change diagram, and show how a substance changes from one phase to another. It is 1 of 3 in the series titled "Phase Changes."

This lesson will introduce a phase change diagram for water, relating energy to progress of a phase change, with labeling including specific heat values, heat of fusion value and heat of vaporization value.

Through an instructional video, games, and activities, students explore three types of change matter makes: physical change, in which only the shape of the matter changes; physical phase change in which matter changes to a different form...

This lesson will introduce a phase change diagram, and show how a substance changes from one phase to another. It is 3 of 3 in the series titled "Phase Changes."

By the end of this section, you will be able to examine heat transfer and calculate final temperature from heat transfer.

[Free Registration/Login may be required to access all resource tools.] Students explore how heat of fusion and heat of vaporization energy are used to create a phase change, and how a phase change can be used to do work.

This lesson will explain how a phase diagram graphically represents phase changes. . It is 2 of 3 in the series titled "Phase Diagrams."

Given the description of a real-world relationship, find the sinusoidal function that models it. The functions in this exercise have a phase (horizontal) shift. Students receive immediate feedback and have the opportunity to try...

When we look up at the night sky, why do we see the Moon's appearance changing over time from a full sphere to a crescent to nothing at all? Find the answers in this interactive resource adapted from the National Air and Space Museum.

This lesson focuses on the states of matter: solids, liquids, and gases. It also discusses the Kinetic Theory of Matter, Thermodynamics, Triple point, Phase Change Graphs and the Heating Curve of Water. It provideds adrawing of a heating...

[Free Registration/Login may be required to access all resource tools.] Defining horizontal translations of sine and cosine functions.

Learn how states of matter can change as heat is added to a system.

Watch different types of molecules form a solid, liquid, or gas. Add or remove heat and watch the phase change. Change the temperature or volume of a container and see a pressure-temperature diagram respond in real time. Relate the...

Bill Nye explains the phases of the moon with an experiment using a baseball, a lamp on a table, a dark room, and a stool or chair that swivels. As the person moves around, the changes in reflected light show the phases of the moon. The...
