Upon further testing, D block “wins” with the worst carbon emissions from a 2000 Jeep Cherokee. #environmentalscience #rstories18

G Block testing carbon emissions from various vehicles today. The 2006 Hummer H2 scored the worst in the class. #rstories18 #environmentalscience

Today’s lab compared the differences between petroleum-based oil (motor oil) and a renewable sourced oil (vegetable/corn/peanut). Motor oil was more efficient, but students noted the disadvantages being the excess smoke and air pollution & that sources will eventually run out.

G Block’s Biofuel lab is set up! From the manure ones, they’ll be harvesting methane. From the yeast ones, they’ll be harvesting CO2. They each gave their hypothesis for which combination they thought would be most efficient/productive. #rstories18 #environmentalscience

A few weeks ago, at the height of flu season, @randolph_school #environmentalscience students did the #moldybreadexperiment. The results are in. #washyourhands #rstories18

What do teachers do after school? Drive to @bellechevre to pick up some goat poo for a biofuel lab tomorrow. #whyrandolph #rstories18

We are THRILLED to have @JeffThornburg speak to the Environmental Science classes about his incredible career and alternative fuel sources he’s used in rocket propulsion. #rocketsarecool 🚀 #rstories17

G Block is testing for the LD50 of various everyday toxic substances in brine shrimp 🦐 today. #rstories17 #gblockrocks #seamonkeymoms #seamonkeys #science

Things I never thought I’d be doing as an educator... hatching #seamonkeys. instagram.com/p/Bf_J2PIAf81/

This week, ES students designed their own lab testing the effects of various substances (like different sunglasses lenses or monetary bills) against UV rays (on UV activated paper). #environmentalscience #rstories17

Big money city! Lab groups were given criteria to include for a fictional city with the only instruction to make it realistic and sustainable, using all the knowledge they’ve learned thus far. #rstories18 #environmentalscience

Thank you for having me over!!! xitter.cf/lisawatson_lisa/status…

“Cookie Mining” to learn about the costs and environmental damages from coal and mineral mining. #environmentalscience #rstories17

G block: future sustainable energy leaders of America! They managed to provide sustainable energy to an electronic city for 2 decades. So impressed. #rstories18

How soil forms and how nutrients are absorbed through different ecosystems. #environmentalscience #rstories17

Our self-sustaining ecosystems are complete! All we have to do is provide precipitation. #environmentalscience #rstories17
