# Magnet Wall Finale

We met with the Middle School Engineers for the big reveal of the magnet wall creations. The kindergarteners were practically jumping out of their seats with excitement and anticipation.

Here is the pirate ship with a treasure box and pink and purple princesses.

The loop-d-loop with each of the students’ names on it as well as custom stoppers.

The tree, unicorn, and special ice cream. Look at the details!

The puzzle pieces that had to fit together and be decorated with dinosaurs, a unicorn, and buildings.

We went out to the Magnet Wall and put the pieces to work.

What an impressive showing! Thank you to our MS Engineers for all their hard work and dedication to this project. You made these kindergarteners VERY happy!

# Welcome Engineers!

Today we hosted the Middle School Intro to Engineering class as part of our project-based learning unit that revolves around the Magnet Wall. The kindergarten “clients” met with their engineer team.

They explored the magnet wall together, discussing pieces the wall lacks.

The Engineers took notes and made specific measurements.

Here are some preliminary ideas.

Big ideas! We will travel to the Upper School in a few weeks to check on the Engineers’ progress. Wait until you see the new STEM Lab where all of the pieces will be created.

# Magnet Wall

A few years ago, our Middle School Engineering instructor and I developed a project-based learning unit that revolved around a newly installed Magnet Wall. If you haven’t seen or heard about Magnet Walls, read on!

From the Kodo Classroom: (https://kodokids.com/outdoor-magnet-wall)

“The Magnet Wall was developed to provide a hands-on, minds-on, open-ended means for experiencing Newton’s Laws of Motion.

When it comes to motion, Newton’s Three Laws summarize everything you need to know about teaching young children about how things move.

I. Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.
II. The relationship between an object’s mass m, its acceleration a, and the applied force F is F = ma. Acceleration and force are vectors (as indicated by their symbols being displayed in slant bold font); in this law, the direction of the force vector is the same as the direction of the acceleration vector.
III. For every action, there is an equal and opposite reaction.

In other words…
1. A moving object will keep moving in that direction until something physically pushes on it. So if the ball is rolling down the ramp and collides with something, its motion will change.
2. It takes more force to accelerate massive objects. If you placed a bowling ball on the ramp, its mass would be greater than the force pushing up from the ramp, which would cause the bowling ball to push the ramp down and probably hurt everyone’s feet. So don’t use a bowling ball! If you used a wooden ball on a ramp the forces pushing on the ball, coupled with the mass of the ball would make it move forward. If you used a tiny marble on the ramp, its small mass would cause it to accelerate down the ramp quickly, because it has much less force than the other forces at work.
3. The third law refers to action and reaction pairs. My force is pushing down on the floor as the floor’s force is pushing up on me. So goes the same for the ball. It is pushing down on the ramp, and the ramp is pushing up on it.”

What a fun way for the kindergarteners to explore Newton’s Laws of Motion! In the coming weeks, the kindergarten students will become the clients of the Middle School Intro to Engineering class. The Kindergarteners will pitch an idea for a new piece for the Magnet Wall that our wall is lacking. The Middle School students will then work to create, build, 3D print, etc., this piece. They will also come to find out that kindergarteners change their minds a lot, ultimately sending the MS Engineers back to the drawing board!  I can not wait to see what ideas come to fruition!

# Magnawall Excitement!

The kindergartners were introduced to our new Magnawall. The installation of the Magnawall is the “hook” for a STEM infused project created by Upper School Engineering instructor, Zack Moore, Lower School Science instructor, Clara Svedlund, and myself. What is the MagnaWall and what concepts does it teach? According to Kodo, the company responsible for creating it, “The Mag Wall is a unique platform for expanding creative play in your classroom or outdoors. Examine slope, cause & effect, momentum and gravity through hands on experimentation! The Magnawall was developed to provide a hands-on, minds-on, open-ended means for experiencing Newton’s Laws of Motion. When it comes to motion, Newton’s Three Laws summarize everything you need to know about teaching young children about how things move.

Students explored the different pieces in preparation for the cross-age level learning that will take place next week.

It was a great exercise in listening to a partner’s ideas and sharing construction ideas.
