Levers homework

Monday, August 9th, 2010

Levers around us ……

Your task is to pick one example of a lever and produce a glogster poster about it.  Your glog must include:

  • A large diagram or photo of your chosen lever.
  • The position of the load, effort and fulcrum must be clearly labeled.
  • The class of lever must be clearly stated.
  • How the lever operates – how is it used to make work easier?
  • Proper referencing for your pictures and text.

You will print out a colour copy of your glog for display in the classroom, and you will leave a comment on this post with the url so that your parents, or anyone else, can view it.  Be sure to make your glog public not private, or nobody but you will be able to see it. And don’t forget to use first name plus initial only (not surname) when posting your comment.

  • Can you explain the difference between accuracy and precision?
  • Do you know what SI units are?
  • Can you choose the appropriate number of significant figures to use in calculations?

Check out this post to discover more about what we’ll be doing this week.  And here’s a brainpop video to help too.

Levers & moments

This is the presentation we used in class Levers & Moments and I am attaching the worksheet as well. Identifying levers

We’ll do a lab activity where we look at balancing a beam using various weights.  Investigating moments

Take a look at this useful site beforehand, so that we can understand moments and turning forces.

And this cartoon clip is helpful in explaining the concepts of balancing moments too.

Finally, here is a worksheet with practice questions on the application of moments using everyday examples.  Moments homework G10 IntSci2

Statistical analysis

Wait a minute – this is maths not biology!  Well, technically, yes it is, but you need a basic understanding of statistical analysis in any science subject so that you can correctly interpret data and make more meaning of the numbers.

Topic 1 – syllabus outline

Useful resources: Your IB Biology study guide, pages 1-2, this document (prepared by Mr Boulton) Statistical Analysis and this powerpoint T-test.  In addition we will be using this very useful site: click4biology

But best of all, the most detailed, thorough and well-explained presentation of how all this is relevant to biology comes from Mr Stephen Taylor at Bandung International School in Indonesia.  Here is a link to his presentation.  If you like it and find it helpful, I’m sure he’d appreciate a comment.

Integrated Science 1

The year ahead …

the long road ahead by qmnonic on flickr

This first document shows the intended timeline we will aim to follow for the year.  Schedule for 10-11

You can cross reference with the syllabus guide, also attached.  IB Biology Syllabus Guide

This is a plan, and therefore is subject to change, but we will aim to stick to it a far as possible.  We’ll start with Topic 1, and pretty well work our way through in order, supplementing material from the HL section as we go.  We must complete 60 hours of lab work over the 2 years of study.  This does not mean you will have to write up 60 lab reports, as many of the labs we do run over more than a single lesson.  And a highlight of the year is our field trip in January to Candaba Swamp.  I will post something specifically about the grading criteria used for labs later.

Welcome to school year 2010-2011!

welcome by Aunt Owwee on flickr

Phew!  Didn’t that summer fly by fast?

Welcome back to all returning students and a special welcome to those just joining ISM.  Get ready for a busy and fun year ahead.  I look forward to our learning journey.

Some ground rules for a happy classroom (and teacher!).

USE THIS BLOG.  I will update it regularly.  This is where to come to follow up on what we have been doing in class, find out what you missed if you were absent, get ideas on homework assignments, or just generally improve your science.

IF YOU DON’T UNDERSTAND, ASK.  It is my job to help you learn.  I cannot do my job unless you communicate with me.  So, if you are having problems with the work we are doing, or are not sure what is required, just say so.  You can email me, or come and see me.

BE ORGANIZED.  High school is busy.  You need to stay on top of your work load.  Use your planner, your phone, whatever you prefer, to keep yourselves organized.  Do not leave assignments until the night before a deadline.  If you do, and you have difficulty, there is no time to sort it out.  If you do the work in advance of the due date, you can show me what you have done and I can give you feedback.

COME TO TUTORIALS.  School does not end at 2.30 – it ends at 2.50 so that you have chance to attend tutorials.  I am usually in my classroom by 6.30 in the morning, and until around 4pm in the afternoon, so come and find me if you need help.  The students that come to tutorials are generally the students with good grades, and the reason they have good grades, is because they use tutorial time.

IT’S NOT ABOUT THE GRADES.  You will soon discover that asking questions like “is this graded?” or “what can I do to get an A?” lead to a very grumpy Mrs D!  In fact, it makes steam come out of my ears.  We come to school to LEARN not to earn grades.  Ask me how I think you can improve your learning and understanding, and you are more likely to get a friendly response.

Ready, set, let’s go!
