Intro to half life phet lab radioactive dating game answers
These labs give the students the adventure of laboratory experimentation without costly supplies, worrisome environmental and safety issues, or time-consuming clean up.
They are from all different areas of science: Biology, Physics, Genetics, Earth Science, Physical Science, and Chemistry. Students will be directed to specific labs in class but there are over 100 labs offered here!
As alpha particles are released during radioactive decay, the mass of the atom decreases by 4, and the atomic # decreases by 2.
The links on this page are all VIRTUAL LABS offered by the Glencoe textbook company.
Change temperature, composition, and thickness of plates.
Discover how to create new mountains, volcanoes, or oceans!
The first lesson, Isotopes of Pennies, introduces the idea of isotopes.
Context This lesson was developed by the Challenger Center as part of NASA's MESSENGER Mission, of which Science Net Links is a partner.
A strong eruption can consist of violent explosions that send great clouds of gas-laden debris into the atmosphere, or may consist of explosions that blast sideways from a collapsed portion of the volcano, as happened in the 1980 eruption of Mount St. Eruptions can alter the land and water locally through lava flows, lahars, pyroclastic flows, and landslides.
Purpose of activity: To reinforce learning about types of radioactive decay (alpha, beta and gamma decay). The idea for the game came from the card game "War" where you try to give your opponent all the cards.
The site also contains well preserved arthropods, sponges, starfish, conulariids, worms, and other soft-bodied organisms, as well as brachiopods, bryozoans, and molluscs.
Some volcanic eruptions are mild and slow, while others are powerful and dramatic.
