The Mysterious Floating Ball

Students in Room 206 demonstrating Bernoulli's Principle...the mysterious floating ball!






"Bernoulli's Principle is the principle that allows wings to produce lift and planes and helicopters to fly. There are many factors that can effect the lift produced under this principle, but in order to understand how and why things can effect flight one must understand how Bernoulli's principle works."


Bernoulli's principle works on the idea that as a wing passes through the air the its shape make the air travel more over the top of the wing than beneath it. This creates a higher pressure are beneath the wing than above it. The pressure difference cause the wing to push upwards and lift is created.

When the students blew air into the flex straw, the Bernoulli ball mysteriously floated in the air...how? Can you explain?

Rocket Day RESCHEDULED

ROCKET DAY rescheduled!

Due to chance of rain, Rocket Day will be THURSDAY, October 28th at 9:00am at Pine Glen School in the side parking lot

Thank you and hope to see you there!

Lovin' Language Arts

We heart books in fourth grade! During Language Arts, students have an opportunity to explore different genres and respond to readings in writing...here's a little glimpse.



Ms. Hayes' class is reading The Orphan Of Ellis Island by Elvira Woodruff. This chapter book is about a boy named Dominick Avaro, a ten-year-old foster child, who travels back in time to Ellis Island in 1908.


Wilfred, Sean, Catherine and Jaimee really seem to be enjoying the book.

Miss Comunale's class is reading Because of Winn-Dixie by Kate DiCamillo. This chapter book tells a story of ten-year old girl Opal. She has just moved to Naomi, Florida with her preacher father. On an errand to the grocery store she finds a homeless dog. Opal is immediately attached to the dog who changes her life.
Above, Liam and Dyviansi are writing in their reading response log. Below, Athena, Sydney and Morgan are going back to the text to confirm their responses.

Sir Isaac Newton

Students in Room 206 have been learning about Sir Isaac Newton's Three Laws of Motion.

The students have completed hands on activities in the classroom learning about each law. Be sure to ask them about the relay race that helped explain Newton’s first law. They also completed an activity called “Move That Truck” for the second law. The most difficult one was for the third law called “Make It Twirl”!How can you begin to guide your child's understanding of these concepts? Without thinking about them, we use Sir Isaac Newton's three laws of motion every day. Newton's first law explains why it is harder to stop a moving car than a roller skate. Newton's second law algebraically relates the force on an object, its mass, and its acceleration. Newton's third law concerns how forces act upon objects.

By relating every day experiences, you can help your child understand Sir Isaac Newton's three laws of motion.Newton's first law of motion is also known as the law of inertia. Newton's first law states that any object will remain at rest or will continue to move in a straight line unless it is acted upon by an external, unbalanced force. A force is a push or pull on an object. Inertia is a measure of the mass of an object. An automobile has more inertia than a roller skate. Any time you want to change the speed or direction of an object, you need to use the appropriate force.Newton's second law of motion relates the concepts of mass, force, and acceleration. In science, acceleration is the change in speed or direction of a moving object.

Force on an object is equal to its mass multiplied by its acceleration. The strength of the force on an object depends upon the object's mass, or how much material it contains, and how fast its speed is changing, or its acceleration.Newton's third law of motion is more commonly called action reaction. For every action in one direction, there is an equal and opposite reaction in the opposite direction; even if the object does not move. Forces always act in pairs, even if the object remains still. While sitting in a chair, you provide a force on the chair acting down towards the floor. At the same time, the chair provides an equal and opposite upward force on you. If this were not the case, you would be sitting upon the floor instead. While you walk, for each step that you take your foot pushes against the floor. As you push, or provide a force, against the floor, the floor also pushes against your foot, propelling you forward. If you try to walk across sheer ice, you must adjust your steps, since the ice does not provide the same force as the floor.

By using every day examples, you can help your children understand Sir Isaac Newton's three laws of motion.

The law of inertia, or Newton's first law of motion, describes how a stationary object begins to move or how the motion of an object changes. Check out below!

Newton's second law of motion algebraically relates an object's mass and acceleration to the amount of force involved to cause motion.

Finally, Newton's third law of motion involves the fact that forces on an object always act in opposing pairs, whether or not the forces cause motion.

We are all looking forward to seeing you all on Rocket Day!
