Pauling Electronegativities in a Flash

Lewis dot diagrams, VSEPR theory and Pauling electronegativities can be used to predict the polarities are small molecules, generally with fewer than ten atoms. Once the polarity of several molecular substances is known, it is usually possible to indicate the relative order of their boiling and/or melting points with some confidence.

Use Adobe Flah to draw faithful animations, with perspective, of the following bonding arrangements: AX and AX2 (linear), AX2 (V – shaped), AX3 (trigonal planar), AX3 (trigonal pyramidal) and AX4 (tetrahedral). Craft a short flash animation illustrating the polarity of these bonding arrangements.

Organelles in Motion

Students make a flash animation illustrating distinguishing features of their assigned organelle(s).

Using a variety of electronic resources, research, and storyboard accurate information about your assigned organelle(s), citing your sources. Select one or more distinguishing features to animate. In your animation, at least one micrograph should be included. Include a written summary.

SWF-ly Animated Angles

Extend the concepts of sine and cosine for angles from 0 to 180

Create a web-based flash animation illustrating the solution to the following math problem:
Using available technology, calculate and record the values, to four decimal places, of the following trigonometric ratios.
sin 70º
sin 110º
sin 47º
sin 133º
sin 69º
sin 111º
cos 70º
cos 110º
cos 47º
cos 133º
cos 69º
cos 111º

Summarize the patterns found in the trigonometric ratios of supplementary angles. Identify if there is a pattern between the tangent ratios of supplementary angles.

Use the patterns identified above to solve the following equations for 0 < o < 180.
a) sin o = 0.3267
b) sin o = 0.8593
c) cos o = 0.6481
d) cos o = -0.3719
e) tan o = 2.1847
f) tan o = -0.5915
