STEM Week 7/8

Presentations: Here is some of the delight driven presentations we heard about today: rocks, hurricanes, chemical reactions, cotton, and compost. 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: This week we introduced another natural force.  Magnetism.  We learned that magnetism is an invisible force or field.  This week we focused the magnetic field and on magnets.   Students learned that a magnet is a special material whose molecules are arranged so that their electrons spin in the same direction.  This molecular structure creates a magnetic force that flows from one side (or pole) to the other.   In class, we placed magnets under a piece of paper and sprinkled iron filings on top of the paper.  This allowed us to see the ma

Week 10

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 ,

STEM Week 3

It is official!  Your kids are amazing.  We threw some pretty big ideas as them yesterday, and they took on the challenge.  Read below for recap, videos, Black Belt Math support material, and suggested homework. Note:  It is best to view our blog on the computer. Presentations:   They did another great Job Today!  I loved all the great science facts and demonstrations shared today.  Reminder:  Presentations are better received with some kind of visual.  Some things that might help:  There is a whiteboard in class and students may have access to my computer (if they would like to show something on a link. ) Science Time: This week we tackled both Newton's 2nd and 3rd Law.  We learned a little about acceleration and learned that items with more mass do not have the same velocity when acted upon by the same force.  Newton's Second law  of motion.   For an object of certain mass, the greater the force applied to the object, the greater its increase in velocity over ti
