Science Week: Day 1

We are nearing the end of Calvert 1st grade, so we decided to knock out the last two chapters in our science book with a dedicated Science Week!  See also Day 2Day 3Day 4, and Day 5.

Welcome to the first day of Science Week!  Today's topics are: Position and Force.  Position is the place where something is located.  We took turns hiding this little magician's assistant in the other room to demonstrate position and to practice using words to describe position.  Under, beside, right, left, near, and far are some of the words that help us tell someone the position of things.

Next we learned that motion is a change in an object's position.  A ball's position can be changed by rolling it across the floor.  We raced bouncy balls and timed them to see how long it took them to travel two meters.

Any time we get to use the stop watch is a good day in Miss M's mind!  Force is the push or pull that makes an object move.  We classified toys with a Venn diagram showing whether they use pushes, pulls, or both to operate.

Gravity is a force that pulls objects toward Earth.  Miss M and Little Guy built a ramp and to test how far the force of gravity makes a marble roll when the ramp is raised 4, 7, and 10 centimeters high.

Conclusion: marbles roll farther when the ramp is steeper!

Increasing the ramp's height!

Our last experiment of the day demonstrated the effect gravity has on a raw egg!  Check out what happened in the video below.  This was a really fun experiment that I highly recommend!!

How have you explored position and force?
