In this classroom experiment the students will observe primary colors mixing together to create a secondary color.
Explore forces, energy and work as you push household objects up and down a ramp. Lower and raise the ramp to see how the angle of inclination affects the parallel forces acting on the file cabinet. Graphs show forces, energy and work.

Discrete and continuum modeling of diffusion processes in physics, chemistry, and economics. Topics include central limit theorems, continuous-time random walks, Levy flights, correlations, extreme events, mixing, renormalization, and percolation.
Create your own sandwich and then see how many sandwiches you can make with different amounts of ingredients. Do the same with chemical reactions. See how many products you can make with different amounts of reactants. Play a game to test your understanding of reactants, products and leftovers. Can you get a perfect score on each level?
Explore what makes a reaction happen by colliding atoms and molecules. Design experiments with different reactions, concentrations, and temperatures. When are reactions reversible? What affects the rate of a reaction?
Percussionist Steven Angel has developed an innovative program that uses rhythm to help struggling students improve their reading fluency and comprehension. Deceptively simple -- a facilitator taps out a basic rhythm while students read aloud -- the method relaxes students, helps them focus, and is effective in after-school intervention programs as well as traditional classrooms.
Students will explore reflection using hand mirrors and a laser pointer in this competitive activity.
This activity is an investigation where students experiment with reflection using plane mirrors.
This is an activity about assessing magnetic activity on the Sun as astronomers do. Learners will select and compare five visible light solar images and identify and label each individual sunspot group. Then, learners will count all possible sunspots from each group and use both counts in a standard equation to calculate the Relative Sunspot Number for each respective solar image. This activity requires access to the internet to obtain images from the SOHO image archive. This is Activity 8 of the Space Weather Forecast curriculum.
This is a set of lecture notes for my course Relativity for Poets at Fullerton College. It's a nonmathematical presentation of Einstein's theories of special and general relativity, including a brief treatment of cosmology.
In this activity, students explore real data about renewable energy potential in their state using a mapping tool developed by NREL (National Renewable Energy Laboratory) to investigate the best locations for wind energy, solar energy, hydropower, geothermal energy, and biomass.
In this activity, students become familiar with the online Renewable Energy Living Lab interface and access its real-world solar energy data to evaluate the potential for solar generation in various U.S. locations.
In this activity, students work through the process of evaluating the feasibility of photovoltaic solar power in 4 different US cities.
In this activity, students play the role of energy consultants to a CEO, assessing and documenting the feasibility, cost, and environmental impact of installing solar power on 4 company facilities with the same design but in different geographical locations.
This video segment explores whether, in principle, renewable energy resources could meet today's global energy needs of about 15.7 terawatts.
In this activity, students will mix paints and create a formula to match a muted color. The formula will be tested. Students will discuss their observations and develop new questions about color mixing to pursue.
In this math meets physics game, learners pretend they are pilots of rescue helicopters and must fly their helicopters to the top of a mountain to rescue lost hikers. Learners first explore the four forces of flight: lift, drag, thrust, and weight. Before playing the game, learners conduct a probability experiment with spinners and record their results in tally tables and bar graphs. They then use their findings to select spinners with the greatest probability of helping them win the game. In a portion of the game, learners use ordered pairs to plot points on the coordinate plane to show their flight path.
Learn about the physics of resistance in a wire. Change its resistivity, length, and area to see how they affect the wire's resistance. The sizes of the symbols in the equation change along with the diagram of a wire.
