Assignment and new topic

Today we have a tiny bit more to do on the lat assignment before starting work on the next topic.  On paper that you already have in your assignment folders, answer the following questions:

1. Define relative atomic mass - http://chemistry.about.com/od/chemistryglossary/a/atomicmassdef.htm
2. Explain why the relative atomic mass of chlorine is 35.5 - http://www.bbc.co.uk/schools/gcsebitesize/science/add_aqa_pre_2011/chemcalc/chemcalc_bothrev2.shtml

Once you've answered these, submit your assignment back to me so I can re-mark them. Next, answer the questions below that relate to the subject we are going to start on today, Humans and the Environment.

1. How many humans live on the Earth now? - http://www.bbc.co.uk/news/world-15391515
2. From the link above, write down the number of births while you were on the site -
3. List  some impacts that we have on the Environment - http://www.bbc.co.uk/schools/gcsebitesize/science/aqa_pre_2011/evolution/humansrev1.shtml
4. What environmental problems can low-cost housing cause? - http://www.driversofchange.com/housing/introduction/impact-on-environment.html
5. List three things that people can do in their homes to reduce environmental impacts - http://www.ecohouseagent.com/

Assignment work

Today we will be continuing on our assignments from last week.  First of all, finish your table for the first pass criteria using the link below. 
Once you're done with that, make sure you've saved and printed your table and put it in your assignment pocket.
Secondly, use your assignment sheet to start on the next criteria for task 2.  You will need to use the same tbale link - http://ptable.com/ to name the elements in group 1 (on the left hand side) and group 7 (second from the right). 
For the different reactions of sodium, use these links - http://wiki.answers.com/Q/What_is_the_Chemical_equation_for_sodium_added_to_water , http://wiki.answers.com/Q/Whats_the_balanced_equation_when_sodium_reacts_with_chlorine_to_form_sodium_chloride , http://wiki.answers.com/Q/Word_equation_for_sodium_and_oxygen

This site will help you answer the last question about how reactivity changes as you move down the group - http://www.chemguide.co.uk/inorganic/group1/reacth2o.html

Atoms Assignment

Today we will be completing some more work for our assignment. For p3, you will need to complete the following table -
Element     Symbol     Atomic number     Mass number     Electronic structure


Use this link - http://www.ptable.com/ to find the information you need and enter it into an excel table.  If you finish early, let me know and you can start on the next section.
This link will help you with the mass numbers, or use the 'weight' part of the interactive table. - http://nobel.scas.bcit.ca/chem0010/unit3/3.1.3_numNeutrons.htm

Assignment

Today we will be completing more of the assignment, looking at the merit and distinction criteria.  With your assignment sheets, use the following websites to help you acheive the criteria for task 3 and 4:

Task 3 - Basic information - http://chemistry.about.com/od/chemistryfaqs/f/aircomposition.htm
Elements, Compounds, mixtures - http://www.chem.purdue.edu/gchelp/atoms/elements.html
Tests for gases - http://www.gcsescience.com/itestoxygen.htm , http://www.gcsescience.com/itestcarbondioxide.htm , http://www.gcsescience.com/itestnitrogen.htm

Task 4 - You can asnwer this on the piece of lined paper we started in class last lesson.

Task 5 - http://www.bbc.co.uk/schools/gcsebitesize/science/add_aqa/atomic/differentsubrev5.shtml
http://www.elmhurst.edu/~chm/vchembook/143Aioniccpds.html . Make sure you compare metal elements to their compounds.

Investigating chemicals

Today we're going to start work on the assignment criteria for the pass grade. You need to make atable explaining the different properties that different chemicals have. Make a table like this in excel:

Chemical name:      State at room temperature:     Reactivity:    Used in:    Number of electrons:

Hydrogen
Sulfuric acid
Copper
Silver
Gold
Potassium
Neon

Use the following websites to help you find information to fill your table in - http://www.chem4kids.com/files/elements/index.html
http://www.hpa.org.uk/webc/HPAwebFile/HPAweb_C/1202115622321
http://chemistry.about.com/od/elementfacts/a/silver.htm
periodic table needed to work out numbers of electrons - http://www.ptable.com/

Make sure you save your work!

Environmental Chemistry

Today we're going to start on a new assignment topic, 'Affecting the Environment'.  Answer the following points in your books, as they will be very relevant to the work you will need to porduce for assessment.

1. How can the following human activities affect the natural environment (including the land, air and water)? Make three dot points for each heading.

Mining -
Oil Drilling -
Burning Fossil Fuels -


2.       Natural disasters also affect the Environment in different ways.  Explain how each of the following can influence the Environment.
Forest fires -
Earthquakes -
Volcanoes -


Mining - http://kids.mongabay.com/lesson_plans/lisa_algee/mining.html

library lesson

Once this video finishes, watch 'we are nothing' which comes up at the bottom.  It covers the material we've been looking at in class really well.

Today we will be using the library to continue our assignments.  We're going to continue with our posters, and start on the final section which deals with space exploration.  Make sure by the end of the lesson you have

• Completed a poster of planets, stars and galaxies (with explanations), and also described asteroids, comets and moons.
• Started the second pass requirement talking about how different wavelengths are used to investigate the Universe.
• If you've finished the first two dot points, use the link below to research the final pass criteria: Looking at manned space missions.
