Key question

1. Sand is insoluble in water and is therefore able to be separated.

2. Salt is soluble in water and is therefore difficult to separate. Salt is an ionic compound and

therefore soluble in water.

Conclusion

1. I think I was pretty successful in separating the substances. I was able to separate the dirt,

water, and salt.

2. To improve this in the future, a finer sieve could be used than a paper towel to separate the

dirt as much as possible.

Questions:

1. The original mixture was water with salt and sand. This is heterogeneous.

2. Sugar and sand could be separated with heat. Sugar would melt and evaporate at a lower

temperature than sand would. This could be heated in a beaker over a hot plate.

3. Fractional distillation separates two liquids from each other. Because alcohol and water

have separate boiling points, this allows fractional distillation to occur.

PHY101 Colorado State Egyptian Pyramids Construction Discussion

The ancient Egyptians most likely used simple machines to build the pyramids. Discuss how you might use one or more of the simple machines to move the massive stone blocks up the growing pyramid, and into their proper places. (Hint: Space aliens are not part of the answer!) How else could you use simple machines?

Hey team, so we have a big presentation this week.here's the assignment:Access the ATSDR website.Collaborate with your group to develop a toxicology treatment plan for the contaminants you outlined in the Contaminant Scavenger Hunt in Week 4.Create a Quick Reference Guide of your group’s treatment plan using a 10-slide Microsoft PowerPoint presentation. Each slide must refer to one contaminant and include the following:Classification of each contaminant, with at least two examples of each contaminant:heavy metalharmful solventvolatile organic compound or vaporpesticideradiationPossible sources of each contaminant within your environmentEffects on plants and humansHow each contaminant is absorbed--route of exposure--and distributed--transportToxic response, or symptomsHow each contaminant is eliminated, or detoxificationEffect on the environmentWhat to do if you are exposed: What is the treatment?Include one additional slide for introduction and one slide for conclusion.Suggested Overall Layout:Cover Slide with everyone’s nameIntroduction slide highlighting presentation content10 content slides with one slide per contaminant including content list above (note it’s ok if some contaminants take more than one slide)Conclusion slide with overall team conclusionReference slidesCite your sources for each slide using separate reference slides at the end.
