We've Got Worms! And More Questions from My Daughters

Earlier this week we had some relatively warm days and were able to do a little spring yard work. My daughters like to try to help with some of it. But like most four and five year old kids, they quickly get distracted. Such was the case when they discovered some worms under some leaves in our yard. 

One of the worms my daughters found this week was picked up by my five year old who put it in bucket. Her younger sister then named the worm Suzy. Now for the last few days they've been adding dirt, water, and grass into the bucket to take care of Suzy every morning and afternoon. 

Suzy has been the inspiration for a bunch of questions about worms this week. I've had to try to explain answers to the following:

  • What do worms eat?
  • Do worms have babies?
  • Do worms hibernate?
For a general overview of the answers to these questions, SciShow Kids has a good video lesson about worms.  

For a more specific answer about worm reproduction, take a look at this short video from the Natural History Museum

And for more about what worms eat, watch this Reactions video titled How Do Worms Turn Garbage Into Compost?

The Chemistry of Thanksgiving or "Why It's Not the Turkey Making You Sleepy"

Tomorrow is Thanksgiving here in the United States. Just like I did last year, on this Thanksgiving Eve I found a video that would have made for a nice Thanksgiving-themed lesson. So even though it is too late to use it this year, bookmark the Thanksgiving Turkey Compilation from the Reactions YouTube channel. The video explains two things. First, it explains how the deep-frying process works and how it helps to make a turkey more flavorful. Second, the video explains why turkey isn't the primary culprit in making you drowsy after devouring your Thanksgiving meal.

How Does Air Conditioning Work? - A Lesson for the Dog Days of Summer

Here in northern New England we don't handle hot and humid weather well. The first heat wave of the summer always sends people scrambling to buy the few air conditioners that are in stock at Home Depot or Walmart. In fact, I was one of those scramblers a couple of weeks ago. This leads me to a new video from Reactions titled How Air Conditioning Works.

How Air Conditioning Works uses excellent drawings and narration to explain the inner workings of air conditioners. The video also explains the environmental impact of the chemicals that are used in air conditioners and the alternatives that are currently being explored.
