He decided to compare filter materials in the solar wax melter. I have three styrofoam box solar wax melters so he compared three filter materials - coffee filter, paper towel, and silk.
He measured and weighed the wax shards so that there was a ball that weighed 2 ounces of wax on each plastic container.
Then on a hot but somewhat cloudy day in August, we put all three solar wax melters out on the sidewalk - one with coffee filters, one with paper towels and one with silk. Dylan said in his report that "we left them out for three days, including nights."
At the end of the experiment, he discovered that his hypothesis (that paper towels would be the best because that is what his grandma used), was wrong. The coffee filter resulted in the cleanest wax by subjective observation. The silk, which took three full days to filter through completely, absorbed the least amount of wax, thus resulting in the most volume of wax filtered through.
He and I printed out and put captions on photo of everything he did. Here he is in front of his board.
I was so proud of him and excited that he wanted me to do this with him. I hope he'll choose a bee project next year also.
1. That's adorable.
ReplyDelete2. Are you going to switch to coffee filters now?
What a bright boy! You have good reason to be proud. And thanks foe the information.
ReplyDeleteI am not going to switch to coffee filters - they are too small for most of the containers that I use so it would be inefficient enough to justify the wax being less clean. I always filter the wax through silk before making it into lip balm and I always filter it again through something - usually panty hose when making candles. So it will be filtered again before I use it after filtering through the paper towel in the solar wax melter.
ReplyDeleteI am so glad I found your blog! As a Mom who loves homeschooling projects (particularly solar ones!) and is starting out with bees here in sunny Tanzania, I found this experiment brilliant! I'd love to know more about solar melters! We will have to try it and post our results on our blog!! Thanks! Rachel
ReplyDeleteIf you explore this blog, I have both a video and a slide show on how to make a solar wax melter on the right column....>
