Season/Energy Activity Part II



Using the same concept in the post below the professor had solar powered fans that he purchased from Radio Shack (see second picture packaging). One was taped at the equator and one was taped at the north pole.

He took us outside and covered up the solar panels. He made a big deal of finding the most direct source of light from the sun and tilting the globe so that the equator was getting the most direct light. He released his hands from both locations and the fan at the equator was going full tilt but the one at the pole was going very slow (because it was getting less light).

This was a great demonstration of how certain parts of the earth receive more or less of the suns energy at different times of the year (causing our seasons).

I love this idea! I teach alternative energy and this would be a great way to demonstrate solar power. I would also be handy teacher 1st grader about seasons.
I enjoy your blog and was inspired to do science notebooks in my science classrooms. My science team has a blog and would love to get feedback.

Thanks for all the wonderful ideas.

Is that Dr. Thompson from the University of South Carolina? He was one of my favorite professors! I use a lot of his ideas in my fourth grade classroom. Thank you for sharing this!

Sandy -

Love your blog. I passed on the simple machines scavenger hunt to some of our 6th grade teachers.

Mrs. Whisnant -

Yes, that is Dr. Thompson. I'm really enjoying his class. He has lots of energy and good ideas.

I'm looking for the same product online and can't come up with anything. I LOVE this idea and would like to tie it into my seasons lesson in 3rd grade.

Do you mind seeing if there's a place online that sells this product? Or if you could provide some more information the product that would be so helpful. I did go to Radio Shack online but didn't find anything.

Thank you for your help! What a great idea :)

I found the kit on Amazon -http://www.amazon.com/American-Educational-4741-Basic-Solar/dp/B005QDPUMY

It is kind of expensive $23 but you would only need two for the demostration and it could be part of a grant write up.

Here are some other seller -

I like the the Solar Made quote of $15. The shipping cost is quite high but if you contact the company directly they might wave the shipping cost.

Secret Messages - How To (Light and Color)

This was fun activity that I got from Roper Mountain Science Institute. They suggested red theater gel to reveal the message, which can get pricy. Another idea I heard was to ask movie theaters to donate left over 3D glasses, which also have a red filter. A guest speaker we had last year said red jello would work. Tried it this week and it worked like a charm. The students thought it was very cool. I found my "attention challenged" students had trouble focusing on making their own secret messages so I was very glad that I had made extra copies of the sheets from the GEMS Color Analyzer book that they could color and then check under the jello.

Picture of the Day - Activity

I attended a training class and a science coach shared an activity that he does with his students to help them differentiate between observations, inferences, and predictions. He puts a picture on the interactive white board as a warm up (he gets the pictures from a variety of sources but uses National Geographic's Picture of the Day a lot). The picture above is from the National Geographic site. He has the students make five observations. Then he makes the students make five inferences. Finally he has the students make five predictions. He does this every day and it really drives home the difference between those three key inquiry vocabulary terms. I've done this activity with both my sixth and fourth grade science classes and the students really got into it and became proficient at telling me the difference between those terms.

QR Project - Open House

Twitter Post Link -  https://bit.ly/3Umic7r I saw this adorable QR code project on Twitter and decided to try it out with a couple of third grade classes. We have several schools in our district who are "Leader in Me" schools and I asked a teacher if I could come in and make them for her open house (you don't need to be a "Leader in Me" school but I know they do a lot of goal setting and mission statements). She loved the idea! I decided to use Flip (formally Flipgrid) to do the recording. The web based program is free for educators and automatically generates the needed QR code. We started on a Thursday. I pulled students into the hall to get a picture of them holding a square piece of paper prior to an ELA block. The paper acted as a place holder for the QR code (which is square) and ensured I got the correct hand spacing so the students looked like they were holding the QR code. I found a spot that didn't have anything in the background. The background...
