CHEMISTRY IB - INTERNAL ASSESSMENT

The Year 12 IB students were super busy last week, completing their Chemistry IA (Internal Assessment) experiments.

This work started last year, when each student researched a chemistry field they are interested in, generated a research question and designed an experimental method.

We also ran two pilot sessions, where the students tested their method, did a lot of trouble shooting and modified their experiment.

Finally, after extensive planning, testing, modifying and refining, they ran their experiments over two full days in the Chemistry laboratory last week. 13 periods of practical work - not an easy task!!

We had a variety of experiments:

James: Electroplating of Copper 

Luka: Analysis of iodised salt

Connor and Adelle: Analysis on antacids

Gracie: Analysis of iron tablets

Cloe': Analysis of Paracetamol tablets

Zoe: Analysis of calcium levels in different milk brands

Vitia: Vitamin C in strawberries

Isabel: Rates of reactions between aluminum foil and an alkali solution

Mikaela: Analysis of Vitamin C tablets

Allegra: Formation of spheres in acidic and alkali solutions

Isla: Effectiveness of soap in different water samples

Jessie: pigment extraction from flowers under different pH solutions

Mikey: Analysis of the pickling process

Our students demonstrated creativity, critical thinking and resilience at every stage of this long, demanding process. Well Done!!

Finally, a special THANK YOU to our lab technician, Catherine Brulez-Marion, for her dedication and hard work with this project. We couldn't do it without you !!
