Design, build, and test a solar oven.
Each page of this activity has a CODAP doc for recording data from sensors. This can be used for ad hoc experimentation or just messing around with sensors to learn…
Semiconductors are the materials that make modern electronics work. Learn about the basic properties of intrinsic and extrinsic–or doped–semiconductors with several visualizations. Turn a silicon crystal into an insulator or…
Use a virtual scanning tunneling microscope (STM) to observe electron behavior in an atomic-scale world. Walk through the principles of this technology step-by-step. First learn how the STM works. Then…
Given the equation of a quadratic function in vertex form, students learn to identify the vertex of a parabola from the equation, and then graph the parabola. Two different quadratic…
In this activity, you will measure relative humidity in the air using just a temperature sensor, by comparing the wet bulb and dry bulb temperatures….
Measure how fast you can react to three different cues: sight, sound, and touch.
In this activity, you will use a computer model to explore what happens to the Sun’s energy when it strikes Earth….
Delve into a microscopic world working with models that show how electron waves can tunnel through certain types of barriers. Learn about the novel devices and apparatuses that have been…
Students solve two problems modeled by quadratic equations. One problem involves profits from a business and the other, water draining from a bathtub. Students graph quadratic equations and use their…
