Introduction to Quantum Physics concepts with an activity demonstrating Heisenberg's Uncertainty Principle, wave/particle duality, Planck's Constant, de Broglie wavelength, and how Newton's Laws go right out the window on a quantum level.

Students are given a figure from a journal article of a northern blot, and are asked to interpret the results, demonstrating an understanding of both the northern blot technique and RNA processing in eukaryotic cells.

This is an activity that students will use M&Ms to gain a better understanding of radioactive dating and half-lives.

Spreadsheets Across the Curriculum module. Students build spreadsheets to forward model an example of exponential decay and interpret the meaning of the decay constant.

This activity is a guided inquiry investigation where students gather data on rate of water falling on erosion. Student will interpret their data, and develop a conclusion from the data. The data will lead to further questions, which can be developed by the students.

In this inquiry lab activity, the students will attempt to layer 6 different kinds of soda pops in a large test tube. The students will have to use prior knowledge of the physical properties of liquids, in particular density, to accomplish this task.

In this classroom experiment the students will observe primary colors mixing together to create a secondary color.

This activity helps students develop better understanding and stronger reasoning skills about distributions in terms of center and spread. Key words: center, spread, distribution

A case for the analysis of externalities (social costs and benefits) in the context of recycling. Drawn from a program in New York City.

This activity uses simulation to help students understand sampling variability and reason about whether a particular samples result is unusual, given a particular hypothesis. By using first candies, then a web applet, and varying sample size, students learn that larger samples give more stable and better estimates of a population parameter and develop an appreciation for factors affecting sampling variability.

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 an inqiury based activity where students are asked to sequence events that have occurred to a block of wood and justify their answers.

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.

A case based upon the environmental devastation of the Aral Sea that illustrates economic concepts of opportunity cost and social marginal cost.

Through this independent research project, students experience the process of doing real economics research using appropriate econometric methods.

This activity requires students to research, design, construct, and test a solar oven. Students will collect data from their own individual oven to combine with research of "real-life" solar ovens in an activity ending scientific paper.

This is an Interactive Lecture Demonstration for resolving force vectors using the suspended block demonstration (1J30.10).

The PhET Activities Database is a collection of resources for using PhET sims. It includes hundreds of lesson plans, homework assignments, labs, clicker questions, and more. Some activities have been created by the PhET team and some have been created by teachers.
