Record your prediction in your notebook. Hold the cart so the rear axle of the vehicles is at notch B on the ramp instead of notch A, and repeat steps 3-7. Predict what you think will happen to the block if the cart starts from notch C. Remember that realeasing the cart from notch C results in the slowest cart speed. Record your predictionin your notebook. Hold the cartaxle of the cart is at notch C on the ramp, and repeat steps 3-7.
PK-S Lab 03 – Lab Report Name: ____________________ Section: ___________________ EXPERIMENT 3: Trigonometric Measurements Procedures: 1. Experimental measurement of the angles and sides of a right triangle: A. Create a triangle by taping a string against a wall and taping the bottom of the string to the floor or a table set against the wall. Make sure that the wall is perpendicular to the floor or table by measuring angle C, which should be 90o. B.
Along the side, write "1", "2", "3" and so on all the way up to twenty (20) or twenty-five (25.) Add color to distinguish between each type of paper airplane. Here are some examples...

After 1 minute has passed, put the wax paper and the potato chips into the trash. Try to remove all of the extra bits from the graph paper, too. Do you notice a grease stain on the graph paper? Tape the paper to a well-lit window so that you can see the stain clearly. 6.
You can conduct a web search with keywords “instructions for paper airplanes” to see some designs and the instructions for making them. Go outside, throw the plane and time how long in seconds the plane flies. Using a stopwatch or the second hand on your wristwatch, record the number of seconds from the time it leaves your hand until the time it lands on the ground. Using a meter stick, ruler, or tape measure, measure the distance the plane traveled. Record your measurements in the data table at the end of this document.
Experiment #1 Reaction Time Purpose and Preliminary Discussion: In this experiment, we tested reaction times for ourselves and various objects. For part 1, the purpose was to test our individual reaction time using a stop watch, measuring how long it would take to start and stop. Part 2 was measuring eye and hand reaction time, using a pencil and piece of paper, the object was to make as many dots as possible within 5 seconds. Part 3, again testing our own reaction time, involved dropping a meter stick from a certain height and recording the time it took to catch it. Part 4 involved using a 2-meter stick and dropping various objects and recording the time it took for them to fall.
Newton’s 3rd Law: For every action, there is an equal and opposite reaction. The racecar demonstrates Newton’s 3rd law because the action that takes place in this project is the air blowing out through straw when the balloon is filled with air. The reaction that happens is the car moving forward. This is considered to be the reaction because it happens immediately after the action happens. The changes that I would make to enhance my racecar’s performance are to use another balloon to achieve the fastest acceleration and the
Teach how to grip the ball and throw it. (Transition) II. Changeup A. Three Finger Changeup 1. Usually the slowest pitch and used to throw batters off.
The dependent variable was the time taken to complete the two trials. Computerised Stromberg Dexterity Test This was a brief version of the SDT, undertaken on a laptop computer using a mouse to drag and drop the coloured blocks into their correct positions. Instead of the 54 blocks in the SDT, the computerised version consisted of just 18 blocks, 6 of each colour. A practice trial was given to allow participants to orientate themselves with the task and to ensure that they had the necessary skills to use the mouse to drag and drop the blocks. The trial was then repeated and the response time recorded.
