Grade 3 Science
Understanding Matter and Energy:  Forces Causing Movement

Below are sites and videos that I will use in class for our Forces Causing Movement unit of study.  Children are encouraged to review these videos and their notes to ensure understanding.

Learning Goal 3.1:  We will identify a FORCE as a push or pull that causes an object to move.

Learning Goal 3.2: We will describe different types of FORCES.

Learning Goal 3.4:  We will learn what DIRECT forces and INDIRECT forces mean.

One of the different types of forces is GRAVITATIONAL force.  Students will learn that gravity is a pulling force, that pulls all matter towards the Earth.  They will also experiment how objects fall in airless vacuum chambers (all objects fall at the same rate).  This is proven in many labs, including the NASA science lab.  Here are two videos that explain this for the teacher, and the student!!

Which one falls first ....the hammer or the feather?  Well, it all depends WHERE you drop them!!!!

Scientists tried it again (with a bowling ball and feather) in an airless vacuum chamber.

We also learn about MAGNETIC force.  This is a push or pull force that ATTRACTS or REPELS objects that contain nickel or iron.  Objects that have the same charges REPEL each other, and objects with opposite charges ATTRACT each other.  I guess it is true---OPPOSITES ATTRACT!!!

TVOKIDS is a great site that has great videos to show magnetic force.

Finally, we learned about electrostatic force.  Here are some cool experiments you can try!

Learning Goal 3.3:  We will describe how different forces can cause an object to stop, start, repel, attract, or change direction.

Learning Goal 3.5:  We will identify different ways in which forces are used in our everyday lives.

Longer Videos for Lunch Time Learning!

SCIENCE MAX  (TVO KIDS)  is a great show to stimulate kid's interest in Science.
