For Friday, April 3, 2015
1 – April 22 is Earth Day. The week of Earth Day, April 18-25, is Climate Education Week.
The week, organized by the Earth Day Network, urges teachers to educate and engage students on climate change.
To help, there’s a free Toolkit that educators can use. It includes a week of lesson plans, activities and contests for K through 12 students.
The lessons meet Next Generation Science and Common Core standards.
There’s a different theme for each day of the week, and the lessons include videos and items for various grade levels.
You can find the lesson plans and more information at ClimateEducationWeek.org.
2 – Look up at the sky tonight. How many stars do you see?
You’d see more if there were fewer unnecessary outdoor lights on homes and other buildings.
April 13-18 is International Dark Sky Week.
Several Michigan state parks will remain open late for night sky viewing during the week. Some parks will host special astronomy events.
Participating parks include Port Crescent State Park in the Thumb.
3 – Biodegradable plastics are better than regular plastics, right?
Not really, according to a study by Michigan State University researchers.
Some water bottles and other plastics are dubbed as biodegradeable. But they don’t break down in the environment much faster than plastics that don’t contain additives.
According to Chemical & Engineering News, plastics labeled as LDPE and PET can remain in a landfill for years, so some manufacturers include additives to help the plastics disintegrate faster.
The MSU researchers designed a study to see if the materials performed as promised. Among the findings: After three years of soil burial, plastic samples with additives did not show any greater physical degradation than samples without them.
