Blogging is difficult because our school district does not allow access to blogging from school computers where all my lesson plans and materials are so I will be doing this at home.
I did complete the lesson plans that I had originally planned and they went reasonably well with my 9th grade chem/physics class
Day1: Introduction to measurement of volumes
Day2: Mixing different volumes of colored water to increase measuring skills
Day3: Limestone rocks and vinegar crstalling growing. This illustrated that different strengths of acetic acid got different results
Day4: Growing copper sulphate crystals using different slution concentrations. Done on a Friday so we could see they results on Monday
Day5: The students wrote an essay recording there thoughts about the experiments
I was disappointed that at present no other teachrs have shown any interest in using these lesson plans.
But I thought that the lessons were a great way of showing the importance of precise measurements and led into discussion of atomic property of mattter as we discussed the crystal structure showed an underlying symmetry to matter
