The end is near!

Thursday, June 2nd, 2011

For our final week of school we will be doing a couple of things.  Firstly, we will be reflecting on our learning in science over the year as a whole, but this semester in particular.  Use this powerpoint to help guide you. Reflection

In science there are a lot of misunderstandings and misconceptions, often published in the media.  Here is a list of some of them.  Choose some and find out the truth!  Happy researching! Science Misunderstandings and Misconceptions

Electricity in context

Friday, May 13th, 2011

plug by Samuel M. Livingston on flickr

For our last piece of the puzzle before we begin reviewing for exams, we are going to take a look at some of the applications of what we have been learning so far.  You can choose one of the questions from the list below (or come up with your own and clear it with Mrs D) then find out the answer, and share it with the group in a meaningful way.  This could be a poster, a video, a model, a powerpoint, a speech – whatever you feel is appropriate to convey the information.

  • How is electrical charge associated with nervous impulses (signals) passing along neurones?
  • What is the difference between AC  and DC?
  • A time traveler from 100 AD arrives at ISM.  Explain to this person the dangers of electricity.
  • How does an electric motor work?
  • What is a fuse and what does it do?  Why are there different kinds of fuses?

 

Electromagnets

electromagnet by cobalt_grrl on flickr

This week you will find out what an electromagnet is and how it works.  You will make a simple electromagnet like the one described on this site.  You will then design an experiment to investigate some factor affecting the strength of an electromagnet.  Carry out your experiment, record data, process and present the data, write a conclusion and evaluate. You need to read the rubrics carefully and make sure you are aiming for the “exemplary” column in all cases.  Good luck and enjoy!

final exam by dcJohn on flickr

3 weeks and counting ….. your semester 2 Integrated Science exam is on Thursday 26th May.  Make sure you check the exam schedule CAREFULLY so that you report in the right place at the right time.

You will need to bring pens, pencils, ruler, eraser and calculator to the exam.  YOU ARE NOT ALLOWED TO BORROW.

Here is the “traffic light” review sheet for semester 2.  USE IT!  Come to tutorials to ask me about anything you don’t understand.  Happy studying 🙂

Ohm’s Law

Friday, April 29th, 2011

We are going to investigate the relationship between voltage, current and resistance in an electrical circuit.  This is called Ohm’s Law.   This might be useful to read first.

Log on to the online circuit construction kit we have been using in class.  Build a circuit containing 1 battery and 1 resistor in series.  Add in an ammeter and a voltmeter.  REMEMBER – ammeters in series and voltmeters in parallel.  Record the values for current, voltage and resistance in this table. Ohm’s Law data

Now change the resistance.  Record the data for current and voltage in your table.  Collect at least 10 pieces of data – or more if you need to, until you see a pattern emerging.  Add in another battery, and take some more readings.  Keep adding in batteries and recording data.  Can you come up with a relationship between each of these three quantities?

Using excel, draw a graph of voltage against current.  Add a trendline, label axes, give a title.  What does the gradient of the line tell us?

Hand in your data tables and graph for grading.  FINALRubric DCP

Current electricity

Monday, April 25th, 2011

There are LOTS of cool links coming up in the blog post.  Explore them.  Try them out.  You will learn stuff!

Tim and Moby at brainpop have lots to say on this topic.  Here are links to one, two, three of their videos.

Here is Mr Dickinson’s “soldier’s marching” analogy: Electric Circuit

This site has really good, easy to follow information on all matters concerning electric circuits.  We will use this online circuit construction site as well.  And watch this: YouTube Preview Image

Electricity terms and symbols

Electricity pillar by Dhammika Heenpella Images of Sri Lanka on flickr

As with any new topic there is new vocabulary to learn.  Find out the meaning of the following electricity terms:-

circuit, series circuit, parallel circuit, current, voltage, potential difference, resistance, diode, ammeter, voltmeter, amperes, volts, ohms

Draw correct symbols for the following pieces of electrical equipment:-

lamp, cell, battery, voltmeter, ammeter, resistor, fuse, switch

Here are a few links to help get you started.  S-coolBBC BitesizeGCSE.com

Lightning by -Qualsiasi on flickr

Start by watching this brainpop video.   And here is our old friend Bill Nye‘s explanation.

Here are a couple more links to some useful information:- this one from enchanted learning and this one from science made simple.  

Now can you explain how lightning happens?

Another useful bit of information.  And download this animation to help you as well.

Flooding from tsunami near Sendai, Japan by NASA Goddard Photo and Video on flickr

No one can have failed to be shocked by the recent earthquake and tsunami in northern Japan. 

The final perfomance task for this unit requires you to take what you have learned about water, solubility, osmosis, and use it to answer this problem:-
