Chemistry Homework – It’s a big one! 😛
Please don’t forget to do the week 12 homework I’ve not had them all in yet.
Homework
You have been comissioned to be the minister of energy in a new country Arcland. There are a few hills, one quarter of the country has coastline, the country is relatively warm but not too warm, there is rain on average two days a week.
Make a presentation for the prime minister to put forward your proposals for all the ways how the country should obtain it’s energy with percentages for each one. You don’t need to explain the exact percentage, just why the number you have chosen is roughly what the country should do. You must choose at least 3 methods of generating energy.
Consider efficiency, environmental factors and the landscape of the country in your presentation.
I’d like at least 15 slides, good detail and a professional presentation will gain extra marks.
Deadline is the 3rd of Febraury. Have fun!
Homework
Either a scientific report or presentation on near earth objects, things to include
What are they?
The risks they pose
What plans do we have in place
How likely are we to get hit by one
Has it happened before?
How do we track them?
Buy a large bag of salt,
time how long it takes a pan of water to boil without salt (calculate the efficiency of your hob too)
put a lot of salt in the water and time how long it takes to boil then.
Make sure to discuss the control variables and why they are important.
Homework:
Make a poster on how a star is formed from a nebula.
Make a poster on the proton cycle.
Bonus Homework:
Watch the film armageddon, do some online research and write a report on the scientific accuracies and innacuracies of the film.
You do the project as a scientific report or presentation. Report style is preferred as my hope is to coach you through how to write a longer scientific report, a vital skill for university and a great skill to learn early. If you’re really keen you can write a report and then put a more bullet pointed version in a presentation.
Project choices
- Radioactive fallout – some questions to address, what radioactive isotopes were realeased at nuclear plant accidents or bomb sites? What type of radiation do they emit? How has this radiation affected the people and environment in the short term and the long term? I would reccomend picking one or more of, Chernobyl, Three Mile Island, Hiroshima or Nagasaki. It might be a good idea to pick more than one of these and compare your findings too. You can pick all of them if you find it really intersting.
2. Uses of radiation – some questions to address, what other everyday uses of radiation are there? What type of radiation do they use? What half lives do they use and why?
3. Any other project of your choice, please email me and let me know if you’d like to do another project.
Deadline 4-6 weeks depending how interesting everyone finds it.
Specific Heat Capacity Experiment Template
Solubility Experiment
Measure temperature of water
Measure the mass of salt.
Pour salt into your water until you have a saturated solution (stir the salt in to help it dissolve)
Note the difference in mass of salt, and calcualte the mass of salt in your water.
Increase the temperature of the water slightly and repeat (pour more salt in).
Repeat until you have at least 6 readings.
At the end, boil off all the water (predict what will happen) and then discuss all your results.
