Updated Atom Builder

September 5, 2014

A couple of my students asked for worksheets to practice drawing atoms and electron shells. I updated the Atom Builder app to make sure it works and to make the app embedable.

So now I can ask a student to draw 23Na+ then show the what they should get:

Worksheet

Draw diagrams of the following atoms, showing the number of neutrons, protons, and electrons in shells. See the example above.

  1. 14C: answer.
  2. 32K+: answer.
  3. 18O2-: answer.
  4. 4He2+: answer.
  5. 32P: answer.

I guess the next step is to adapt the app so you can hide the element symbol so student have to figure what element based on the diagram.

Embedding more Graphs (using Flot)

September 8, 2013

Here’s another attempt to create embeddable graphs of mathematical functions. This one allows users to enter the equation in text form, has the option to enter the domain of the function, and expects there to be multiple functions plotted at the same time. Instead of writing the plotting functions myself I used the FLOT plotting library.

Investigating the Heart Online

August 30, 2013

BodyXQ has one of the most impressive interactive apps of the heart that I’ve yet seen.

You can explore the heart in 3D while it’s in motion. You can see the valves open and close, while hearing the beat. I’m going to have to show this to the class tomorrow.

3d Molecule Viewer

July 23, 2013

An excellent 3d viewer for molecules.

An excellent 3d molecule viewer. (The actual app has a lot smoother animations than this.)

An excellent 3d molecule viewer.

In addition to the existing molecules, you can import any number of others if you can find them in one of the right formats (PDB, SDF or MOL molecule definitions): the ligand.info: Small Molecule Meta Database is a good source for SDFs.

An Online Microscope

July 5, 2013

Now that I have a new set of microscopes I didn’t think I would actually need to have an online, simulated microscope to show samples. However, I thought having a series of picture that I could scroll through would be useful to illustrate microscopy concepts such as depth-of-field when I talk about them to the whole class. Once I’d created the depth-of-field simulation, I figured it would not be too much extra trouble to put in a few different magnification levels. Now I have this embeddable online microscope simulator.

It’s started off with a single fly wing as a sample, but I’ll be adding to it as I take more pictures.

Depth of Field Demonstration: On a Simulated Microscope

July 2, 2013

At higher magnifications, microscope lenses will only be able to focus on layers within your specimen. You could take a series of images with different focal planes and stack them together, but without a camera mounted on the microscope, getting images to line up right for focus stacking is quite the challenge. The alternative is focusing in and out until you get a feeling for the three dimensional shape of the specimen.

Since I don’t have a camera mount I’ve created an html5/javascript page that simulates focusing in and out of a sample. It’s embedded above, but a direct link is here.

You can use the knobs to the right of the image to adjust the focal plane. You should be able to see hairs on the top and bottom of the transparent wing.

Use Tone Matrix to generate music by clicking squares on a grid.
