Well, the unit is over. We looked at freshwater, performed experiments, and then took a look at ocean water. I was going to have the kiddoes conduct a project on density and salinity, but, felt writing skills in greater need of honing, so our project was to write an imaginery story about strolling on the ocean floor.
Making Stone
Tomorrow, we return to the FOSS geology unit. Talk about having to rewrite something. The entire 9-week unit was geared more towards 8th grade. I toned it down a bit, explained more where needed and interjected material I felt was more critical to learning than retrace the exploration of the Grand Canyon. All-in-all, the FOSS unit is great, but needed tweeked. For this week's class, the munchkins will use sodium silicate as a cementing agent (matrix) in the formation of sedimentary rock. We will first make sandstone, coal and shale, then move onto limestone. I can't wait until we do geologic time and dinosaurs - grrrooowwwlll!!!
Speaking of Dinosaurs
Well, sort of, this time I'm talking about the tiny sea critters that inhabited our area 360 million years ago. Keystone Central School District (Lock Haven/Renovo area) has a great website on Red Hill http://www.kcsd.k12.pa.us/renovo/dig/ -- about the fossil finds from the Devonian period. Check it out. The kiddoes in that school district did a fantastic job with this lesson.
