5 Phenomenal Forces we are learning about in Science

This term we have been learning about various forces and types of movement in science class. Have a look at what we’ve learned so far!

5 Phenomenal Forces
Muscular Force
The muscles in your body are attached to bones. Muscles pull on these bones. This is called muscular force.

Gravitational Force
Planets pull objects toward them. Earth pulls you and other objects toward it. This pulling force is called gravity.

Frictional Force
When two objects slide over each other they rub and push against each other. This pushing force is called friction.

Buoyancy Force
What happens to the water when you jump into a pool? Some of the water splashes up. Your body pushed down on the water and the water pushed up on you. This made the splash. This upward pushing force is called buoyancy.

Magnetic Force
A magnet is a piece of iron or steel that attracts other pieces of iron or steel. This attraction can happen naturally, or can be created by people. Magnetics either push away or pull together.

Dear Parents,
Come join us on April 13th when Scientists in the School program visit our classroom to lead our students through a morning of experiments that will test and explore forces. Discover the science behind magically removing a table cloth from underneath the dishes without breaking any. Encourage a magnet to defy gravity while investigating magnetism. Charm a snake to learn about electrostatic force. Design a marble run and explore the effects of friction. Learn how to make a tornado with the flick of your wrist!
If you are available to volunteer your time on April 13th from 9:00am to 11:30 am, please send me an e-mail or a note with your son/daughter. Thank you in advance your continued support.

What’s up next in science?

Structures and Mechanisms
If you are not available to volunteer on April 13th, you can join us on June 6th when Scientists in the School program visit us again to build our knowledge on structural strength and stability. Students will be junior engineers for the day as they explore the difference between man-made and natural structures. They will also investigate how the strength of a material can be altered by its shape. Students will create structures and learn the impact of forces acting upon them. Lastly, students will take up the challenge to design, build, and test a bridge!
