1. Creativity and Innovation
Students demonstrate creative thinking, construct knowledge, and develop innovative products and processes using technology. c. use models and simulations to explore complex systems and issues.
d. identify trends and forecast possibilities.
2. Research and Information Fluency
Students apply digital tools to gather, evaluate, and use information. Students:
c. evaluate and select information sources and digital tools based on the appropriateness to specific tasks.
d. process data and report results.
Students need a clear understanding of horizontal projectile motion and vectors in Physics.
This lab should be taught half way through the chapter of projectile motion so students are familiar with needed equations.
Students should be comfortable with percent error equations and be able to reflect on what their results mean
Correctly calculate the flight path (ΔX) of an object using a horizontal angle with given velocity and mass of the object.
The Students will be given a lesson on basic projectile motion and how to calculate the ΔX using given angles of zero, speeds and masses of an angry bird.
They must use these formulas to calculate the horizontal displacement of the angry bird
The Students will have a screen shot of the angry bird’s game. They then must calculate how far the bird will travel with a given velocity and mass if it is shot from a horizontal angle.
The students must show their work and provide and hypothesis of a distance they believe their bird will travel.
Each student will have a different bird, which will have different masses and in turn velocities so each group will have different answers.
After they provide their hypothesis, they can go online and use the game to test their hypothesis.
Once the students see how far the bird actually travels in the game, they can calculate their percent error
Then see where (if) they made mistakes in their calculations.
Students will than write a lab report discussing their results and what was difficult or too easy during the lab.
The students will be partly graded on their percent error from the calculations from the screenshot and the actual recorded distance in the game. (%60)
The other part of their grade will be a lab report in which they will reflect on what they learned and how the exercise helped them understand horizontal projectile motion. (40%)
As this is a high school level lab, the accuracy of their calculations will carry more of the grade than the lab report.
This lab calls for students in groups of 3 to have access to a computer.
A scientific calculator such as TI-80 and above will also be used in order to ease calculations
I can see by the calculated percent error’s from the students lab reports if I taught them the equations and explained the presented material thoroughly enough
From the lab reports I can also see what the students found difficult or even too easy from the lab, and make changes for the next time I run the lab
Projectile Motion in physics can be taught along side another topic in a different class very easily. The lab could be done during a time where the students are learning about trebuchets or medieval warfare that also use projectile motion.
I could also show modern day examples of projectile motion such as the punkin’ chunkin’ in the Midwest.
