MOVIE (groups of 2/3) TOPIC: PHYSICS IN REAL LIFE
You are going to create a movie (not more than 5 minutes) that illustrates the importance of physics in real life. You have to select and area and expand it.

GRAPH USING EXCEL TOPIC: GENERATING DATA AND GRAPHING A LINEAR EQUATION
Investigation Making a Pendulum Clock
Follow the procedure to make the pendulum clock and develop the Table 1 where you get the values for the Length of the Pendulum and the time for 1 swing (back and forth).
The graph will be obtained using excel (look for tutorials) and the final graph (one page) must have a main title, y axis is the period T in seconds and the x axis the length in cm.
Include the equation of the line following y = mx + b and the value of r squared. The equation and r2 must be calculated by Excel.
Include your picture holding the pendulum clock
Attach your values for the period found with your pendulum clock (handwritten)
What Is R-squared? R-squared is a statistical measure of how close the data are to the fitted regression line. It is also known as the coefficient of determination, or the coefficient of multiple determination for multiple regression.
The definition of R-squared is fairly straight-forward; it is the percentage of the response variable variation that is explained by a linear model. Or:
R-squared = Explained variation / Total variation
R-squared is always between 0 and 100%:

BALLOON CAR COMPETITION TOPIC: VELOCITY AND ACCELERATION
You are going to make a balloon car that we are going to test in a 3m by 1m space. The car must cross the finish line (3m) within the 1 m width of the space.
The only thing you can use are wheels from another car (minimum 2 wheels) and everything else must be fabricated by you (you can not take a toy car and put a balloon on top). The day of the competition bring more than one balloon in case your balloon explodes,
We are going to test your designs in the hub so design your car early and test it before the day of the competition to be sure it works. As in the other projects, don't leave this project to the last minute since you had one week to prepare it. The grade will be based on the average velocity of your car compared to other cars (car competition).
At the end we will have a race and the winner will get bonus marks.

HOT AIR BALLOON PROJECT (GROUPS OF 2) TOPIC: FORCES PRODUCE MOVEMENT
The basic principle behind hot air balloon physics is the use of hot air to create buoyancy, which generates lift. In real life, a hot air balloon consists of a large bag, called an envelope, with a wicker basket suspended underneath. A burner (with power typically of several megawatts) sits in the basket and is used to heat the air inside the envelope through an opening. This heated air generates lift by way of a buoyant force.
Your project is to build a hot air balloon that will lift a small load up to the ceiling (we will test your balloons in the library). You have to test your hot air balloon and do the calculations of the inside volume of your balloon and the buoyant force.
Your report's title is THE PHYSICS OF HOT AIR BALLOONS and will be only one page with the picture of both partners and the balloon you are going to test. There is one report per group.
You have to research for your project, use your own words and include the sources. A sample calculation is shown in:

WATER PROPELLED ROCKET CONTEST (GROUPS OF 2)
The purpose of this project is to launch a rocket propelled by water. The rocket must not be taller than 60 cm, with an aerodynamic design and its own stand. We are going to launch the rockets in the football field and the rocket that stays the longest time will the the winner. We are going to test your rocket vertically and then with an angle (projectile)
You have to test your rocket without water and then with different amounts of water to get the highest initial velocity and therefore altitude.
Your report is titled, The Physics of Rockets and must explain Newton's Third Law, performance of your rocket with different amounts of water and your calculations including free fall and projectile motion. Include a picture of your team and rocket.
