![The Effect of Electrode Shape on the Electroplating of Copper [Chemistry experiment]](http://upload.wikimedia.org/wikipedia/en/thumb/b/b6/Copper_wire_comparison.JPG/220px-Copper_wire_comparison.JPG)
Here’s a fun experiment that I did with my friend over the holidays just to prove another friend wrong. DESIGN Purpose: To determine if physical deformations (ie. bending, etc.) of the copper electrodes used in the electroplating of copper will affect the amount of copper electroplated. Hypothesis: In electrochemical cells, spontaneous redox reactions convert chemical [...Read more...]

Another fun experiment we did to show our teacher that his remarks were indeed false. Design Purpose: To determine the effect of electromagnetic radiation, specifically ultraviolet radiation, on an iodine clock reaction. Hypothesis: The iodine clock reaction is famously known for its sudden colour change which does not occur immediately after the two reactant solutions [...Read more...]
One of the reasons why the IB is so popular in the world is because of its rigorous standards in Internal Assessments (eg. Maths Portfolios, Design Labs, etc.) and External Assessments (May/November exams). However, what should you, the student, know about this confusing and sketchy subject matter? Internal Assessment The Internal Assessment is used by [...Read more...]
