This collection of videos, animations and documents comes from the NCSSM AP chemistry online course. This introduction provides practice and demonstrations of basic concepts of chemistry such as significant figures and the distinction between physical and chemical changes.

This activity provides a demonstration and lab exploration of one of the main "building blocks" of the periodic table of elements: chlorine. During the lab, students compare physical and chemical properties of chlorine compounds.

An interactive applet and associated web page defining a circle. The applet shows a circle where the user can drag the center and a point on the circle. The radius line supports the definition that all points on the circle are a fixed distance from the center. The web page has the definitions of all the circle-related objects, such as diameter, chord etc, with links for each. Applet can be enlarged to full screen size for use with a classroom projector. This resource is a component of the Math Open Reference Interactive Geometry textbook project at http://www.mathopenref.com.

This new version of the CCK adds capacitors, inductors and AC voltage sources to your toolbox! Now you can graph the current and voltage as a function of time.

Build circuits with capacitors, inductors, resistors and AC or DC voltage sources, and inspect them using lab instruments such as voltmeters and ammeters.

An electronics kit in your computer! Build circuits with resistors, light bulbs, batteries, and switches. Take measurements with the realistic ammeter and voltmeter. View the circuit as a schematic diagram, or switch to a life-like view.

Build circuits with resistors, light bulbs, batteries, and switches and take measurements with laboratory equipment like the realistic ammeter and voltmeter.

An interactive applet and associated web page that show the properties of a circumcircle of a polygon. The applet shows a regular polygon where the user can drag the vertices to reshape it and alter the number of sides. As the polygon is being varied, the circumcircle is shown, passing through all vertices. The text describes two ways to calculate the radius of the circumcircle, depending on what you are given to start. Applet can be enlarged to full screen size for use with a classroom projector.

An interactive applet and associated web page that demonstrate the circumference of a circle. The applet shows a circle with a radius line. The radius endpoints are draggable and the circle is resized accordingly. The formula relating radius to circumference is updated continually as you drag. Introduces the idea of Pi. The formula can be hidden for class discussion and estimation. See also the entries for circumference and diameter. See also entries for radius and diameter. Applet can be enlarged to full screen size for use with a classroom projector.

The app is currently used in a research study which aims to investigate how Augmented Reality can influence STEM (Science, technology, Engineering, and Mathematics) education and if it can improve pupils interest towards STEM.
Its main purpose is to enhance interest and curiosity levels in STEM, particularly focused on topics like astronomy, space exploration, and space technology.

This lesson covers the definitions of differences between weather and climate. Students will discuss local climates in Washinton state, then they will dicsuss climates around the world and collaborate to determine distinct attributes of different climates. For this lesson, the focus will be on the ice block activity to demonstrate how a changing climate affects the local ecosystem.

The Climate Momentum Simulation allows users to quickly compare the resulting sea level rise, temperature change, atmospheric CO2, and global CO2 emissions from six different policy options projected out to 2100.

This National Weather Service interactive visualization includes outlook maps for different types weather predictions. The map includes temperature and precipitation predictions for up to 3 months out, as well as predictions for tropical hazards, weather hazards, and drought. Further data is easily accessed.

This interactive visualization is a suite of weather and climate datasets as well as tools with which to manipulate and display them visually.

This is a rich compilation of resources and tools to help decision-makers across the US identify their local climate threats and vulnerabilities and reduce their risks from impacts of climate​ variability and change. As part of President Obama's Climate Action Plan, the toolkit was developed by NOAA in partnership with NASA and other departments and agencies in the U.S. Global Change Research Program.

ClimateSim is a fast and simple climate modeling and simulation tool. It is a web app that is freely available to anyone interested in climate science. ClimateSim allows users to model scenarios of greenhouse gas emissions in the current century and simulates the first-order response of the earth system. ClimateSim makes climate simulation accessible in a simplified form and provides an easy-to-use simulation platform for performing virtual climate experiments. ClimateSim is primarily targeted as a science education tool for undergraduate and advanced high-school students in physics, environmental science and related courses. Instructors can use ClimateSim to illustrate climate-change concepts, demonstrate dynamic relationships between climate variables, and assign simulation-based exercises as part of their courses. It is also an appropriate and accessible tool that policymakers, journalists and others can use to get a better understanding and working knowledge of the basics of climate science.

This is a simulation that illustrates how temperature will be affected by global CO2 emission trajectories. It addresses the issue that even if global emissions begin to decrease, the atmospheric concentration of CO2 will continue to increase, resulting in increased global temperatures.
