PeriodicTable from wisegorilla.com

We have, and will continue, to look at the Periodic Table.  Make sure you bring the paper version you were given in class with you to every lesson.  It is an important document.

Here are some resources that may be useful.  Read through the notes, and say thanks to Mr. Boulton for producing them, (with a little help from wikipedia). Classification of Elements   Comparison of groups in the periodic table

Here is the link to the video demonstrating what happens when you mix the more reactive alkali metals with water.  We will do Li and Na in class, but nothing quite as exciting as this!

Have a great no homework weekend 🙂

maximum heart rate 214 by Laurel Fan on flickr

In class this week and next we will be working on a lab dealing with factors affecting heart rate.  Your task is simple – to design, carry out and write up your findings on how a particular factor affects heart rate. 

Begin by listing all the factors you can think of that might influence how fast or slow your heart beats.  Decide on one independent variable to test, and write it in the form of a research question.  Next write a hypothesis, including justification.  Then plan an experiment to test your hypothesis, remembering to state clearly how you will control all the variables you mentioned earlier. 

Then comes the fun part – performing your plan.  You may need to ask, beg, bribe some of your classmates or family members to participate.  Once you have your data, process it and present it appropriately, explain your findings, and evaluate both your results and your method.  Suggest improvements for next time. 

Phew!  That should take a while…. This is a great opportunity for you to boost your IA scores and gain complete on the various aspects of lab grading.  Here is the  IA rubric.
