Instructional Ideas

• Have the class build a model of the cell before and after enzymes have been put into place to speed up a chemical reaction; discuss the effects of this reaction on the overall cell
• Instruct students to brainstorm scenarios in which chemical reactions do not take place as they should and a dysfunction occurs; discuss the ramifications of such issues

Classroom Considerations

• Due to the short nature of this video, it is important to use it as a supplemental tool when teaching a unit from an already existing lesson plan

• This video is hosted on YouTube

Pros

• Simple video contains vivid animations that engage individuals with all learning styles
• Plain and simple language allows those individuals who are not native speakers of the language to better understand a complex concept
