We Provide STEM Education for Kids!
This week we built a fishing rod. The fishing rod used pullies to extend and pull in the hook. I would really appreciate it if everyone stuck with their teammates because some people left their teammates to go and play. So, before you leave, please finish your project and make sure your partner is complete as well.
Last week in class we built drag cars. This was a more difficult project, so I didn’t get time to go over the lesson. Essentially, the drag car is propelled forward by the spinning gear, which propels the car forward. When the button was pressed on the base, it connected the spinning gear on the base to the dormant gear on the car. The base was able to spin the gear on the drag car which continued to turn, propelling the car forward.
Today in class we built flywheel cars. A fly wheel is a device that stores rotational energy. The motions of the flywheels continue because of inertia. This allowed the car to move forward, even after the wheels have stopped! This was very enjoyable for the kids because they had an opportunity to race against each other. See you next week!
Hello everyone!
My apologies for the later post. Last week we built sweeper cars! This was a fun way to learn about gears and rotations. We noticed that a gear turns another gear an equal circumference to itself, for example when a larger gear turned a small gear, the small gear rotated extremely fast because it needed to be rotated according to the circumference of the larger gear.
This week we worked in teams and that worked out nicely. Next week you will be working in teams but with other students. I may include a prize for the fastest group! Next week we will be building a Fly Wheeler.
Today we built a hammer. This build taught students about friction and force. Depending on the tightness of each gear the friction is different. The students discovered that larger gears had a higher friction than the smaller gears. The force of the hammer was able to push the axle into the gear as well. Next week I would really appreciate it if students would check if each piece was inside their kit to make sure no one will have trouble finding anything.
Today in class we built motor cars. Although it was a little out of the student’s comfort zones, the majority of them were still able to complete it. This project helped them with the fundamentals of building with Lego, the parts and the instructions. Next week we built balances which the student’s enjoyed.
Hello Parents,
Today in class we built beam balances. The beam balance teaches students about the simple machine- the lever. In class, we discussed the correlation between length and weight and why one side of the balance dropped. Next week we will be building a hammer. Please complete the homework assignment and the worksheet provided in class.
