Teaching about the five senses can be a ton of fun. I found some great videos for you to use while learning about senses. Instead of watching all the videos at one time, I suggest breaking your viewing into sessions. Watching them all at one time will be too much information at one time leaving your kids overwhelmed.
When we learned about senses I showed an introduction of the 5 Senses then discussed it. Then I introduced each individual sense while doing simple experiments to teach how they work and why that specific sense is important. Watching, discussing then doing an experiment helps kids to understand concepts on a higher level than just using one learning style. For experiment ideas scroll past the video links.
