Balloon Car Presentation

Transcript: Bessy- My Balloon Car Speed per Meter Graph! Acceleration Graph! Distance- The length of a path between two points. Our goal for the balloon car lab/race was to get our car to go five meters. My car only went four meters. Speed- The ratio of the distance an object travels to the amount of time the object moves. Formula: distance/time=v (speed) We had to find the speed of our cars. To be more exact, we found the instantaneous speed. Instantaneous speed- The speed is measured at a particular instant. For example, every time our balloon car crossed one of the meter marks the person timing the car stopped their timer. We then used that time and the distance to find the instantaneous speed. Average speed- Average speed is computed for the entire duration of a trip. Formula: avg. distance/avg. time Not only did we have to find the speed per meter for each trial, but we also had to find the average speed for each trial. Acceleration and Instantaneous Acceleration: Acceleration- the rate at which velocity changes. Instantaneous Acceleration- how fast a velocity is changing at a specfic time. We had to find the acceleration of our car per meter. In order to find the acceleration we already had to know the speed because the formula for acceleration is change in velocity divided by total time (vf-vi/t). I had positive acceleration, but I also had negative acceleration. Displacement- the direction from the starting point and the length of a straight line from the starting point to the ending point. When a ball bounces off a wall and comes back some you can find displacment. Sure, it may have went a total of 10 feet but now it's only 5 feet away from where it started. Vector additon- combining of vector magnitudes and direction. Resultant vector- the vector sum of two or more vectors. Frame of Reference- a system of objects that are not moving with respect to one another. Example: The people sitting at the different meters timing the cars could be considered the frame of reference. Linear Graph- display data from straight-line parts. Vector- a quantity that has magnitude and direction. Constant Acceleration- a steady change in velocity; the velocity of the object changes by the same amount. Example: This didn't relate to any of our balloon cars; I know it didn't relate to mine. Velocity- speed and direction in which an object is moving. Example: You could have found the velocity for our balloon cars; they went in one direction for the most part and we already had found the speed. Nonlinear graph- curve connects the plotted points (data). Relative Motion- movement in relation to a frame of reference. Example: The cars being pushed by the balloon.

Transcript: DPIM mutations' background the lab's mutational strategy data from literature alpha fold predictions What is Y2H? Yeast two-hybrid screening system is a molecular biology technique used to discover and analyze protein-protein interactions and protein-DNA interactions by testing for physical interactions (ex.: binding) between two proteins or between a protein and a DNA molecule, respectively. The mutations (Pol32 permutations for Y2H assays X Pol1) we are interested in are as following: Pol32:AlphaFold predictions: predicted aligned error plot DPIM area: DED GY: confidence level of the residues according to AlphaFold: D -> A CONFIDENT E -> A CONFIDENT D -> A VERY HIGH G -> A CONFIDENT Y -> A CONFIDENT

Balloon Car Presentation

Transcript: Our balloon powered car! My partner and I predicted that with a light base, we would have a balloon car that would glide across the floor easily. After a few trials with the car, we realized it was not going to work, so therefore, our hypothesis was proven incorrect. My partner and I thought this was a good idea because it is light and there wouldn't be much weight added to the car. Balloon Car Presentation For our base, we used a paper towel roll. Here's our balloon powered car in motion! Watch it down below! For wheels, we used ping pong balls. Shake n' Bake Our finished project ! Hypothesis We had the balls spin on the axle of the wooden skewers. My partner and I put Styrofoam pieces around the balls so they wouldn't move.
