Force and Motion

I asked these third grade students to repeat the physics investigations we did in class, so I could record them in slow motion. All three of these investigations illustrate the concept of inertia- an object at rest tends to stay at rest until an outside force acts upon it (Newton’s first law).  Vocabulary included mass, gravity, friction, and force.

Can you whip off a tablecloth without the dishes coming with it?  Why?
Investigation 1

A hex nut is on top of the yellow ring.  How can you move the ring and make the hex nut fall into the bottle?
Investigation 2

A golf ball is on top of a toilet paper tube which is on top of a tray.  How can you get the golf ball to fall into the cup of water without touching it? Why doesn’t it sail off with the pie plate?
Investigation 3

If you repeat the tablecloth investigation, make sure the tablecloth doesn’t have a hem. 🙂

I demonstrated this one too.  I hit the side of the tray which had more mass and the three balls fell into the glasses.  It is fun to try this with eggs. It is all about inertia!

Fireflies

First grade wrote in their journals about our firefly lab yesterday.  Their teachers sent me some pictures.  I am so impressed with what they remembered and I am so glad they shared them with me!

Turtles

After learning about a turtle’s anatomy, habitat, and life cycle, we observed our own turtle and fed him a worm. Then the Pre-First class made turtles and wrote a fact they remembered.

Blue Moon

Usually there is one full moon each month.  A blue moon is defined as any time there is a second full moon during a calendar month, according to NASA.  The last blue moon was in 2012. The next blue moon takes place in January 2018 — and that year will be a double blue moon year.

I saw the Blue Moon in Hilton Head.

Science in the Rockies

I just returned from Science in the Rockies with Steve Spangler. Steve is a leader in science education and believes engaging children in memorable hands-on experiences is the only way to get kids excited about science.  He also feels passionately about equipping teachers.  This was the best conference I have ever attended and I can’t wait to use the materials and ideas with your children!
