Photosynthesis and excitement are not generally two words used together unless you happen to be a plant biologist, but we happened on a series of science videos on YouTube that are quite fun. They are targeted at middle school age kids and older.
There are some views the presenter voices that I don’t agree with, but even my kids (who are sticklers for right and wrong) enjoyed these and decided that it is not important to completely agree with someone in order to learn from them. Good lesson.
Lots of fun. Yes, sciency geeky fun, but fun nonetheless.
