Stone Table STEM Club

Presentations: Wonderful presentations!  Centripetal Force, Jellybeans, Chocolate, Atoms Presentation Reminders: Provide an image or a hands-on example.   Highlight key-words, or use bullet points on an index card. Practice presenting before you come.   Project your voice, so that everyone can hear you.  (I usually say to bounce your voice off the back wall.) Science Time: We continued our unit on Simple machines this week.  This week we learned about wheels. This is the video we watched.  In our lab time we built balloon cars with wheels and axles.   Here is a link to learn more about wheels:   http://www.explainthatstuff.com/howwheelswork.html Math: Keep up the good work mastering facts!  I will be working this week to post more black belt math challenges. Please note: It is okay to stay on a level as long as it is necessary to master the material. Perhaps some students it will need to take several weeks to master +1 and +2 addition bef

Presentations: Great Job on the presentations! Presentation Reminders: Provide an image or a hands-on example.   Highlight key-words, or use bullet points on an index card. Practice presenting before you come.   Project your voice, so that everyone can hear you.  (I usually say to bounce your voice off the back wall.) Science Time: We continued our unit on Simple machines this week.  This week we learned about pulleys. This is the video we watched about pulleys.  It would be well worth watching again if you can fit it in. https://youtu.be/9T7tGosXM58 Here is another video.  It does a much better job of describing how pulleys work.   In our lab time, we placed pulleys on a rod and used the pulleys to help us lift our load.  Each time we added a pulley we were able to see that it helped us use a small force over a longer distance to lift a heavy load.  Here is a link to learn more about pulleys:   http://www.explainthatstuff.com/pulleys.html , 

Presentations: Here is some of the delight driven presentations we heard about today: Trees, Venus Fly Trap, Earthquakes. Presentation Reminders: Provide an image or a hands-on example.   Highlight key-words, or use bullet points on an index card. Practice presenting before you come Project your voice, so that everyone can hear you.  (I usually say to bounce your voice off the back wall.) Science Time: We started our unit on Simple machines this week.  We started with levers. This is the video we watched about levers.  It is silly but kept their attention.  It would be well worth watching again if you can fit it in. In our lab time we placed a long board on a fulcrum (jack-stand) and placed our load on one end (a concrete block)  We adjusted our beam in different ways to explain how a lever helps to overcome the resistance of the load.   Here are a couple of links about levers:   http://eschooltoday.com/science/simple-machines/what-is-a-lever.html
