Radioactive Dating: Looking at Half-Lives Using M&Ms part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
Kathleen Babich, South St. Paul Junior High School, South St. Paul, MN, based on an original activity retrieved from http://www.ucmp.berkeley.edu/fosrec/McKinney.html also with the help of Jenni Johansen (other 8th grade science teacher at So. St. Paul Junior High School
This is an activity that students will use M&Ms to gain a better understanding of radioactive dating and half-lives.

Hurricanes Unit Overview part of EarthLabs for Educators:Hurricanes
LuAnn Dahlman, NOAA; John McDaris, Carleton College
In this EarthLabs module, students will do hands-on experiments and study hurricanes in satellite imagery and visualizations. They'll also explore over 150 years of storm data to find out when and where these storms occur. If students are studying hurricanes during hurricane season, they can monitor the position and status of storms in real time. Hurricanes can serve as an exciting entry point into understanding everyday weather, or a culminating topic for an Earth system or environmental science unit.

Investigating soil acidity: Comparing pH and buffering capacity of various soils part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
Patricia Babolian, Red River Area Learning Center, Moorhead, MN based on an original activity, Fake Lakes, from GEMS Acid Rain
In this activity students investigate soil pH differences and buffering capacity as it relates to acid rain, interpret and present their findings, and develop a new, experimental question.

Density Differences part of MnSTEP Teaching Activity Collection:MnSTEP Activity Mini-collection
Mary Holmberg Eden Valley-Watkins Elementary School Eden Valley, MN Based upon an original activity from Houghton Mifflin, DiscoveryWorks, p. E52
In this lab activity, students determine density differences of water samples with varying temperature and salinity levels. Students synthesize information to predict the effects of oil in given water samples.
