Does the power of the light source shone on a solar powered car affect the distance a solar powered vehicle needs to be from the light before it starts to move? = =

=  __Task 1__  = = __: Answer these Questions__ =

__ 1. What is a circuit? __ A circuit is a path which lets electricity flow.

__2. What are the parts of a circuit?__ A conductor (wire), voltage source (battery), load (bulb or buzzer) and the switch.

__3. What are the symbols for the parts of a circuit?__ __4. What is a parallel circuit?__

In parallel circuits, the electric current can follow more than one path. __5.____What is a serie____s__ __c____ircuit?__ A series circuit allows electrons to follow only one path.
 * Parallel Circuit**
 * Series Circuits**

__6. How does solar energy work?__ __The solar panal abzorbes the sunlight and converts the sunlight into electiricity__

==  __Task 2: List your independent, dependent and controlled variables:__  ==

__1. Independent variable__ The wattage of light

__2. Dependent variable:__ Using a ruler

__3. Controlled variables:__ The car

=  __Task 3: What is the hypothesis for your experiment?__  = My hypothesis is that the 100 wattage light bulb will make it work from the closest distance

=  __Task 4: What equipment do you need for your experiment?__  = __A ruler,peg, siccers,lamp and light blubs.__

=  __Task 5: List all steps in the method of your experiment (try and include a diagram or video that helps explain):__  = 1.Get the peces for the car and make the car. 2.Get a lamp and some light bulbs(different wattage light bulbs. 3.Get a ruler and a peg. 4.Get the lamp and put the light bulb in. 5.Get the car and sine the lamp over it. 6.Get the ruler and measure how far it needs for the car to start working.

__**Task 6: Observation and discussion**__

Note down what you noticed as you did each experiment. Try and include an image or a video or photos of your experiment.

__Experiment 1 Observations:__

__Experiment 2 Observations:__

__Experiment 3 Observations:__

= __Task 7: Results__  =

Take a screen shot of your results table. Upload it and put it here:

__Task 8: Conclusion__
Write a statement that says whether your hypothesis was wrong. If you were wrong, why were you wrong?
