Welcome to our second day of Science Week! Today we investigated simple machines and magnets. A simple machine is a tool that can make it easier to move things.
First we tried to lift a textbook with one finger, but it was too heavy! So we built a simple machine using a marker, a ruler, and some masking tape.
|First, tape a marker to the table.|
|Second, balance the ruler on the marker.|
|Third, place one end of the lever (ruler) under the textbook.|
Next Miss M tried to pick up and carry a heavy bottle of vinegar.
|"I can lift it, but it's too heavy to carry far," said Miss M.|
|"Look! I can pick it up much easier now!"|
We didn't do any hands-on investigations with ramps. Both kids have seen their 88-year-old great-grandmother being pushed up and down ramps (and sometimes steps!) in her wheelchair many times, so we had a brief discussion about that and moved on.
Our last activity of the day was playing with magnets! Miss M sorted a pile of office supplies according to what she thought would stick to a magnet and what wouldn't.
|She predicted correctly on all but one: the pencil's eraser band got pulled by a magnet!|
|Sometimes the attraction is so strong it works right through your hand!|
|Little Guy was "training" his magnet and making it do tricks.|
What's your favorite thing to do with magnets?
