…Earth science classes to life with dynamic modeling environments that students can use to create and test scenarios and explore concepts of geological systems and deep time. We’re also expanding…
…data shows a slowly increasing heat flux as the object slowly warms up. As an interesting test case, Figure 2 shows two rotating sensors, one placed precisely at the center…
In this activity students will design, build, and test a bridge made with file folders to see which design is the strongest.
…efficient multiplication approach. This illustrates our basic approach: creative thinking validated by empirical data. We will continue to develop and test creative ways to speed the software and improve the…
…on Mother Nature to give you an opportunity window. For example, you can test how big an obstacle should be in order to produce this effect. You will find that…
Students build model buildings and test them for sturdiness using a shake table and a force sensor.
…and unconfined aquifers, discover how water moves around gaining and losing streams, and explore the difference between rural and urban area aquifers. Create your own landscapes to test ideas about…
…3) simulates Ernest Rutherford’s experiment to test this model. He shot alpha particles—very high-energy, high-speed, positively charged helium atoms—at a thin piece of gold foil. If the positive part of…
…to develop, test, and analyze sets of technology-supported diagnostic classroom assessments for middle school physical science and life science. The validity studies address cognitive, inferential, and instructional aspects of validity…
…beautiful,” he says. “But sometimes, when shot at close distance without the distraction of beakers or test tubes, ordinary reactions such as precipitation can be very beautiful.” Beautiful Chemistry is…
