 Topics in Physics, Day 4

By: Kilali and Sara

  Today was full of excitement! We started off by using a projectile launcher. We calculated how far away a cup can be on the floor for the marble inside the launcher to land inside the cup. After doing the calculations we were able to successfully get the marble inside the cup. We did have a few complications, we had accidentally moved the range of the launcher. To solve this problem we did trial and error to get the same range that we started with.

After doing this we had a quick lesson on Force. We proceeded to uses a force plate to see how many Newtons we could produce by jumping, pushing, and hitting the plate. It was fun to see how many Newtons we could produce. It turns out that Kilali can produce the most amount of Newtons between Alex and me. 


Sara Prepping for Parachute Launch

At the end of the day, we did an Egg-Streme Parachuting Experiment. Our goal was to have a plastic egg filled with water land on the floor without cracking.  Everyone had different ideas and ways to make the parachute. Alex made a big rectangular parachute with four strings attached to the corners. Kilai made a circle with eight strings attached to it. I made three circle parachutes with eight strings attached to each circle. 


   After this, we did a quick experiment that focused on showing Inertia. We put three cups of water with a paper plate on top, three paper towel rolls cut in half on top of the plate and aligned with the cups, on top there were plastic eggs with rocks inside. We had to smack the plate without hitting the cups and get all three eggs into the cups. This was a really fun way for learning how inertia works. I can't wait to see what fun things we learn tomorrow!

Action Shot of Drop Zone   Topics in Physics, Day 3 Photos By: Sara - Blog By: Alex We started off the day today with an activity called "The Drop Zone." The goal was to have a cup with a marble in it slide down a 2 meter long fishing line "zip line" and have the cup dump the marble in a specific target zone before the end of the line. We used paperclips, weights, and precisely carved pieces of paper that we attached to the inside of the cup to have the marble roll through a tube and into the target zone. The main concept that we covered in this activity was the idea of projectile motion, which we later dove into deeper with equations and practice problems. Kilali Measuring Free Falls Later on in the morning we got a lesson on free falls and acceleration due to gravity, which we followed up with an experiment that demonstrated the possible accuracy (and inaccuracy) of using human response time to make precise measurements. We did this by dropping a ball from a speci...

 Topics in Physics, Day 5 By Alex and Kilali Sara working on the Hotwheels activity Today we did a lot of fun lessons and activities. We started off doing some practice force equations since we started learning about forces yesterday. These were pretty difficult, but it made me very happy when we got the correct answers in the end. Afterward, we did an activity with the Hotwheels. In this activity, we set up a pully system with the Hotwheels and where we had washers hanging off the table which was connected to our Hotwheels car. We would attach a different amount of washers each time we ran the experiment. We did this activity to see the change in acceleration of the Hotwheels car for each amount of washers we used. This activity was very fun and exciting. I really enjoyed seeing how fast the car would move depending on how many washers we had attached to the other end of the pulley.  Sara and Kilali working on the collisions activity In the afternoon we started working on mom...

Topics in Physics, Day 6 Photos By: Sara - Blog By: Alex Kilali Connecting the Spiral Track Segments The Building Blocks of our Coaster We started off the second week of our A-Term by doing some practice and review into the concepts of energy and momentum, and doing a few fun projects that applied these concepts. We built roller coasters! Using some of our advanced lab tools and our new skills of interpreting data from a graph, we were able to see the acceleration and velocity of the car that we shot down the rollercoaster. The first rollercoaster we made in the first half of the day went well and was able to launch the card using a chain and a motor. The second one didn't really go as planned. We had to use improvisational engineering skills to change most the design of the rollercoaster, and it ended up being twice as large as it was supposed to be according to the instruction book. This was a very fun experience, and I definitely learned a lot about having to work...
