10y4 ISA prep.

Today we will befinishing the research for our ISA, ready to sit section one on Monday. 

The section 1 paper will ask you questions about the types of variables in your experiment, as well as writing a method.  You will also need to identify any hazards that might need to be considered, and finally draw a table for your results.

To prepare, first complete your research sheet.  Secondly, or at home, answer these questions -

1. Look at  the powerpoint on this link ( copy 'results table independent dependent variable' into google search. click on the link near th top titled - How science works: variables.  Don't worry about the physics stuff).   Where do the independent ad dependent variables go in the results table? (slide 16)
2.  What is the independent variable in our experiment? http://www.ncsu.edu/labwrite/po/independentvar.htm
3. Explain what the dependent variableis we will measure? - http://labwrite.ncsu.edu/po/dependentvar.htm 
4. What control variables can you think of tat we will try to keep the same 
5. Complete this quiz - http://www.funtrivia.com/playquiz/quiz97961224e8.html 
6. Explain what a hypothesis is - http://www.bbc.co.uk/schools/gcsebitesize/dida/using_ict/questionnairesrev1.shtml   
7. Watch the video on this link, use earphones if you have them. What was your hypothesis? Did the experiment support it? Clicking on one of the other objects will open the video in Youtube, and then you can click on them and see what happens.

6. You should also spend some time thinking about the hypothesis we wil be testing.  what do you expect to see? - www.science-spark.co.uk/.../Emulsions%20ISA%202011%20Student%20Instructions%20website.docx

10y4 research lesson

Today we wll be filling out our research sheets.  The most important pat (although al the boxes on te back of your sheet need to be filled in today!) is the hypothesis - copy this down word for word:

 The output voltage from a solar cell depends on the area of the solar cell exposed to
the light.

Centre number - 62307         Centre name - Cheney School
When filling out your planning sheet, make sure you talk about the voltage instead of the current.  This link might be useful in deciding how to run your experiment - http://www.bbc.co.uk/schools/ks3bitesize/science/energy_electricity_forces/electric_current_voltage/revise5.shtml

Ask me if you have any questions, and make sure you have the seet filled in and handed back to me at the end.
