Photons Monochromatic Light White Light Rainbows Gene Expression DNA

Topics

Photons

Monochromatic Light

White Light

Rainbows

Description

Make a whole rainbow by mixing red, green, and blue light. Change the wavelength of a monochromatic beam or filter white light. View the light as a solid beam, or see the individual photons.

Topics

Gene Expression

DNA Transcription

Protein Synthesis

Cells

Stoichastics of Molecular Interactions

Description

Express yourself through your genes! See if you can generate and collect three types of protein, then move on to explore the factors that affect protein synthesis in a cell.

Topics

Polarity

Electronegativity

Bonds

Partial Charge

Dipole

Description

When is a molecule polar? Change the electronegativity of atoms in a molecule to see how it affects polarity. See how the molecule behaves in an electric field. Change the bond angle to see how shape affects polarity.

Neurons

Cells

Description

Stimulate a neuron and monitor what happens. Pause, rewind, and move forward in time in order to observe the ions as they move across the neuron membrane.

Topics

pH

Dilution

Concentration

Acids

Bases

Description

Test the pH of things like coffee, spit, and soap to determine whether each is acidic, basic, or neutral. Visualize the relative number of hydroxide ions and hydronium ions in solution. Switch between logarithmic and linear scales. Investigate whether changing the volume or diluting with water affects the pH. Or you can design your own liquid!
