Science Stop : Simple Machines Are Useful!


Once again, Mr. JR has contributed to our classroom learning!




Check out his collaborations about Matter and Light 

Mrs. Yollis met Mr. JR at the Google Teacher Academy in NYC, and they planned these science segments when there.



The topic for this session was SIMPLE MACHINES!
A simple machine is a basic tool used to do work.





Mrs. Yollis shared this great site about levers

Notice the fulcrum and the lever. 




Tweezers have a lever





A bicycle wheel is a wheel and axle. 









An incline plane wrapped around a cylinder is a screw.









Do you see any simple machines in your house?
(incline plane, wedge, screw, lever, wheel and axle, or pulley)

Tell us about them!


Which one do you use the most? 

Do you have any science questions for Mr. JR?

Science Stop: A Colorful Science Lesson




Last week,  Mrs. Yollis' and Mrs. Ranney's second and third graders teamed up with Mr. JR's high school chemistry students via a Google Hangout.   The high school students gave a fabulous science demonstration about color and light.

Mr. JR. welcomed the class! Everyone loved his new colorful hairdo!
 
 

 First Mr. JR. and his students taught the elementary students a great song about the rainbow. The seven colors of the rainbow are also know as the spectrum.

Have you ever heard of ROY G BIV?
What does ROY G BIV mean?







Next, the high school students demonstrated how to mix color pigment to make new colors! Watch and learn!






The students used a prism to split white light into the 7 colors of the visible spectrum. They used the word refract

What does refract mean? 
 
 
 

We ended the call with a chant about light!





Do you know any additional facts about light that you can add? 

What was your favorite part about the science lesson?
