How do strong and weak acids differ? Use lab tools on your computer to find out! Dip the paper or the probe into solution to measure the pH, or put in the electrodes to measure the conductivity. Then see how concentration and strength affect pH. Can a weak acid solution have the same pH as a strong acid solution?

Ancestors, Archaeology and the Anishinabek: Bridging the Past into the Future

Representatives from 10 sovereign Native American nations in Michigan, five State of Michigan agencies, two universities, and three private organizations collaborated to develop two short curriculum units, one for 3rd grade and one for 5th grade. Each grade level unit includes five lesson plans and support materials for teachers using information from two archaeological sites provided by MDOT and cultural, historical, environmental, and indigenous knowledge provided and vetted by Michigan Native American tribal partners participating in the project. The lesson plans use the Inquiry Arc of the College, Career, and Civic Life (C3) Framework and focus on specific Michigan Social Studies Standards. The lesson plans also provide links to Michigan English Language Arts (ELA) literacy standards, as well as science and math applications.

Beer's Law Lab
Conditions of Use:
No Strings Attached
Rating

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.

Bug Hunt
Rating

“Bug Hunt” uses NetLogo software and simulates an insect population that is preyed on by birds. There are six speeds of bugs from slow to fast and the bird tries to catch as many insects as possible in a certain amount of time. Students are able to see the results graphed as the average insect speed over time, the current bug population and the number of insects caught. There are two variations to try for the predator, one where the predator pursues the prey and one where the predator stays still and captures insects that pass nearby. In the first case the “bird” catches the slow insects and the faster ones survive, reproduce and pass genes on. The average speed of bug should increase over time. In the second case the faster bugs come near to the bird more often than the slow ones. The slow ones survive more, reproduce and pass their genes on.
