“Juggling Earth’s Resources”
BES students were educated and entertained on Tuesday, September 26, in the BES gymnasium by Jay and Leslie Seifert-Cady. We want to thank the Hays Arts Council and Brenda Meder for again making it possible for them to be part of our school year. Some of the science and environmental concepts covered are as follows.
10 Earth Science conceps from “Juggling the Earth’s Resources”:
- Things made of atoms.
- Atoms are tiny and go together in groups called molecules.
- Water molecules are H2O (two atoms of hydrogen, one atom of oxygen).
- The water cycle has four parts – evaporation, condensation, precipitation, and accumulation,
- Carbon dioxide molecules are CO2 (one atom of carbon, two atoms of oxygen).
- Oxygen and carbon dioxide go in a cycle through plants and animals.
- Burning fossil fuels adds CO2 to the atmosphere.
- More CO2 in the atmosphere causes climate change (global warming).
- Solar and wind technology create energy without adding CO2 to the atmosphere.
- We can help the environment by learning to Reduce, Reuse, and Recycle.
As a bonus, here are five ways we can all help the environment, courtesy of Bridging the Gap (more at bridgingthegap.org).
- Give up bottled water.
- Wash your laundry in cold water.
- Switch to compact fluorescent lightbulbs.
- Set your thermostat at 68 degrees in winter, 78 degrees in summer.
- Cut your gasoline use by one fourth.
