Building interactivity into a Moodle course can be difficult, especially if you are lacking JS/YUI experience. With the eocontenteffect and eocententquestion TinyMCE plugins available on my GitHUB you can easily add interactive effect.
After installing the plug-in a button will appear in your TinyMCE HTML editor.
No scripting is required! Simply highlight the text you would like the effect applied to, click the effects icon and choose an effect either the What? or Show/Hide effect. You can use these interactive effects to help maintain interaction and interest in your content.
What? Hidden Text Effect
This effect is best used with single words or small phrases of text since it is inline. Users must click the What? text to reveal the hidden words. You can easily modify the reveal word. Here are some examples.
What? EasyOChem is the coolest thing since sliced bread.
Show/Hide Blocks of Text Effect
Similar to the What? effect but more appropriate for larger blocks of text.
BVO (brominated vegetable oil) is used in the food industry as an emulsifier. BVO is synthesized by the bromination of oleic acid. Normally the density of a fatty acid is less than that of water, however upon brominating its density increases to about the same as waters density (~1 gm/mL). Becasue BVO is not soluble in water it forms an emulsion and appears cloudy. Typically only a few ppm (parts per million) is required. It's what makes some soda pops appear cloudy. BVO is prohobited in foods in some other countries. The FDA still allows it in foods i the Unites States.
