Week 16 : the crunch time before midterms begins

Our first challenge of this was to seperate sand salt birdseed and iron filings. This was so we could exploit the properties of matter. Our attempt did work in the end but it took several tries. We discussed the different properties of water and ethonol and discussed how we could tell which was which. Then upon Friday we touched the surface of the process called diffusion and we seperated ethonol from water and lit it on fire. I hope this week is as just as exciting
