Look inside a battery to see how it works. Select the battery voltage and little stick figures move charges from one end of the battery to the other. A voltmeter tells you the resulting battery voltage.
The PhET project at the University of Colorado creates "fun, interactive, research-based simulations of physical phenomena." This particular one deals with Beer's Law. "The thicker the glass, the darker the brew, the less the light that passes through." Make colorful concentrated and dilute solutions and explore how much light they absorb and transmit using a virtual spectrophotometer! The simulation is also paired with a teachers' guide and related resources from PhET. The simulation is also available in multiple languages.
Explore bending of light between two media with different indices of refraction. See how changing from air to water to glass changes the bending angle. Play with prisms of different shapes and make rainbows.
Watch beta decay occur for a collection of nuclei or for an individual nucleus.

This is a long-term inquiry activity in which students investigate locations they believe harbor cellulose-digesting microbes, collect samples, isolate them on selective media, and screen them for cellulase activity. These novel microbes may be useful for the production of cellulosic ethanol. In the process they learn about plating techniques, serial dilutions, symbiotic relationships and enzyme specificity. Two methods are provided, one focusing on isolation of pure microbial strains, the other focusing on finding symbiotic communities of microbes. The companion activity is here: https://www.glbrc.org/outreach/educational-materials/bioprospecting-cellulose-degrading-microbes-filter-paper-assay
How does the blackbody spectrum of the sun compare to visible light? Learn about the blackbody spectrum of the sun, a light bulb, an oven, and the earth. Adjust the temperature to see the wavelength and intensity of the spectrum change. View the color of the peak of the spectral curve.
This introductory Blogging Rubric can be used with any "blogging" assignment. It is very basic but covers what is expected of the students.
Determine the value of two fractions you have chosen (which are represented as points on a number line). Then find a fraction whose value is between your two fractions and determine its value. This manipulative is the same as "Bounded Fraction Pointer" but there is no arrow to help the user determine the value of a fraction between the two endpoints. Bounded Fraction Finder is one of the Interactivate assessment explorers.

Then find a fraction whose value is between your two fractions (using an arrow on the number line as a guide) and determine its value. Bounded Fraction Pointer is one of the Interactivate assessment explorers.
This activity allows the user to view box plots for either built-in or user-specified data, and experiment with outliers.
Break-Even analysis and the effect of changing Fixed costs, Variable Costs, and Selling price on Profit/Loss
Try to move points (one at a time) C, B, and D C for a change in fixed cost B for a change in selling price D fora change in variable cost
Historical tool demonstration, showing a man using a broad ax and adze to prepare timber for construction.
Tracking of income & expenses for student budgeting.
This activity utilizes an online interactive simulation (PhET.colorado.edu) that allows students to explore and manipulate the subatomic particles that comprise the atom. Students also explore atomic mass, ions, nuclear symbols, and the periodic table. A link to the simulation and a downloadable file that includes a pre-lab, a student activity guide, and a post-lab assessment. The simulation also includes other inquiry opportunities and a game.
This student inquiry activity walks students through the construction of basic electrical circuits using an online simulation and asks them to record their observations. This activity is a great activity to 'spark' interest in learning about electricity.
