Enzymes Internal Assessment

Today we spent half the period discussing your first official Internal Assessment and the remaining half of the class reviewing your test on Topics 3.1-3.5 and 7.1-7.4.

You will be investigating the decomposition of hydrogen peroxide by catalase.  

On Wednesday March 7th, you must submit a completed Design for this experiment.  Essentially this Design would be suitable for submission to the IB.  You will have Friday March 9th to play in class and tweak your design.  You will be graded on the Design that you submit on March 7th and this will be the last grade you have before midterms.

Your Design should have:

A Title

Research Question & Background Information

Null Hypothesis (Ho) and Alternative Hypothesis (Ha)

Table that lists the Independent & Dependent Variables, as well as Controls.

Materials (with uncertainties)

Photograph of experimental set up ** You do not need to include this at this time, however you do need to identify a space for it in your paper. ** You do not need to include a protocol diagram.

Method (listed in steps).

A data table

A couple of things to keep in mind: 

* Your lab design can not be identical to another student (even if they are in a different period).

* If you research information on this topic, you must cite it in your Design.  This includes information contained in the Background section.

* As you are designing the experiment be mindful of how you will collect the data, since you will actually be doing this experiment.

* Internal Assessments count for almost 25% of your overall IB grade.  Since unlike a test, you know exactly what your Internal Assessment will cover, you should take the extra time to make it perfect.

* Refer to the rubric you received for the Osmosis Design Lab for more details on the requirements.
