Join Civil Engineer Carrie Feuer P.E. as we do hands-on explorations of how water goes from dirty to clean.
Display: books on engineering and on the water cycle.
Opening: Ask who attended http://carolsimonlevin.blogspot.com/2016/07/on-your-mark-get-setengineer.html. Discussion what is an engineer? What do engineers do? Show engineering process diagram.
Read: All the Water in the World by George Ella Lyon
Talk about what the title means…All the water in the world is all the water in the world – dinosaurs drank the same water you do.
Introduce: Mrs. Feuer (“Foyer”) – she is a civil engineer who works with water – what would be the problem with water? It gets dirty but we have to use it again – how?
Carrie Feuer took kids through the process of making dirty water clean.
1. Kids all added dirt, sticks, stones, grass etc. to a bucket of water –> dirty water
2. Screen the water (rough garden screen to get out the big items -- Carrie Feuer showed a bunch of things that should and shouldn’t be put down drains
3. Let the water settle so dirt and heavy stuff sinks to the bottom – 5 minuntes – spent time discussing where water is found (air, sea, rivers, clouds, sinks, toilets, drinking glass, swimming pool, etc.)
4. Poured off the water, left solids in pail
5. Added alum & chlorine* to clump solids and dis-infect, stirred for 5 minutes – while stirring read: The Magic School Bus at the Waterworks by Joanna Cole, finished with the last “experiment” in 11 Experiments That Failed by Jenny Offill.
6. Voila – clean water!
