Science (and some math)

We worked on measuring the size of satellites this week in science.  The kids had to make a prediction by looking at pictures, which satellite was the largest.  Then the kids were given pieces of color coded string to measure.  Had a good experience in learning how to measure a piece of string that was longer than our meter stick.  We will have more measuring practice during our watermelon afternoon.  The largest satellite was the ocean satellite that had many solar panels, smallest satellite was a hummingbird.  How can that be?  There are two types of satellites, artificial and natural.  Have your kids explain what is the difference.
