Project Log

Date	Hours	Tasks / Work Done	Obstacles Encountered	Modifications to Car
8/23	1hour	We drew our idea of what our car would look like. We started to gather materials.	Since it was our first time building a solar car, it wasn’t easy to come up with a building plan.
8/30	1hour	We worked on creating our body.	It took us a long time to cut the body.
9/6	1hour	We built supports to support our body’s sides.	It was hard to position the support bar.
9/13	1hour	We taped and glued our car.	The glue kept breaking apart.	We put the sides up for speed.
9/20	1hour	The bars to hold the passenger kept falling off.	Putting the passenger in the car.
9/24	1hour	We cut the wood for the ball-holder and cut wood for more security.	It was hard to put our wheels and motor on.
10/1	1hour	We cut a hole to fit the motor.	Time went too fast.
10/8	1hour	We put on our back wheels.	We accidentally punctured the top right side of our car.
10/15	1hour	We attached the wires and alligator clips to our motor and battery pack.	It took us a long time to find good gears.
10/22	1hour	We finished our motor system. There is a motor, switch, and battery pack. We will have to place it so that there is not too much weight in one place and so that everything fits on our car body.	Time again went too fast. It is hard to get things done in a small amount of time.
10/29	1hour	We put on the switch and the motor.	The motor fell off when we were running the car. We will have to add it back on next time and figure out how to secure it better.	The switch and the motor were added to the car.
11/6	1hour	We put the motor on (again!).	Our car went backwards! We had the wires on the wrong terminals. We decided to mark them so that it doesn’t happen again.
1/17	1hour	We put on the solar panel. The car looks awesome!	We had to replace the wheels.
1/24	1hour	We put on the guide so that we could run it on the guidewire. We decided to put it underneath the car.	We needed to make sure that we put the guide on straight and that it was not going to rub on the ground.	guide is on the car
1/31	1hour	Worked on Web Page.
2/28	1hour	Worked on Web Page.
3/6	3hours	Worked on Web Page.
3/9	1 hour	We ran our car outside
3/11	1hour	We ran our car outside
3/16	1 hour	We ran our car outside on battery and on solar panel
3/17	3hours	Worked on Web Page. Put on The Wind Shield on the car.		added part 1 of the wind shield
3/20	1hour	Worked on Web Page. Put on the other part of The Wind Shield on the car.		added part 2 of the wind shield
3/21	30min	Worked on Web Page.
3/22	1hour	Finished the Webpage. When we get back from our spring break we are going to try to make changes to the car so that it will run faster.
4/3	1.5	We added a 3cm x 3cm piece of wood to the car so that we can have our race number displayed. We also put velcro on our wires so that they would not interfere with the wheels or gears.		Velcro to hold wires. Pieces of wood to display race numbers.
