How to Use This Journal
Keeping a record of the design process is an important part of Junior Solar Sprints. This presentation is here to guide you along. Included are important investigations that will help your team understand the science behind your model solar car. All blue slides are explanation slides, no action needed. All yellow slides require responses. You must fill in and answerYou can change the color, theme, font or anything that doesn’t change the content. You can add more investigations or any additional information, but that is optional. Anything in blue is an example. To use this presentation go to “File
” “
Make a Copy...” and save that file to your own Google Drive or computer hard drive.Feeling stuck? Email me for an example journal from previous years at Ktomasicchio@transoptions.org

A good definition explains a word by telling you what the word is, the class of object and its characteristics
Example: Water is a liquid made up of molecules of hydrogen and oxygen in the ratio of 2 to 1. What Class CharacteristicsYou try! Define Solar Power:Solar Power is a form of _ _ _ _ _ _ made up of ____ and _____from the _ _ _. Hint: the missing sections are hyperlinked to websites that contain clues.Definition: Solar PowerSlide5
Investigation: Solar Panels
Hypothesize on what things may affect how your solar panel works.(The formula goes, If _____ then ____ .) Idea1

Investigation: Solar Panels
Choose one of your hypotheses to test. Design an experiment that will help decide if your hypothesis is true. What we are testing: If electricity is generated by the solar panel if it’s inside.How we are testing: Hook the solar panel up to a small motor with a wheel attached. While inside, see if the solar panel will generate electricity to cause the wheel that is attached to the motor to spin.

Here are the gears included in your kit. To determine the size of each gear, count the “teeth” around the outside.
What are the sizes of gears in your kit, from largest to smallest?Investigation: Gear RatioWhy are there 2 of each size? What is the difference?Slide10
Investigation: Gear Ratio
Hypothesize on how gears matter to your model car construction. Example: (The formula goes, If _____ then ____ , because ___________)
1
If my model car’s gears don’t fit together my car won’t move because it’s the connection of gears that transfers motion/energy to move my car

Materials
IMPORTANT - you have to use: 1 motor (from our provided kit, no modifications) 1 solar panel (Pitsco Ray Catcher model only) 1 soda can (to act as your passenger, must have tab attached)We include all the pieces necessary to build a model car but you can use your creativity when it comes to the wheels, chassis, axles, motor mounts and race line attachment.Use the chart on the following slide to assess your choices for the different components of your model car.
You need to use an empty SODA CAN. N
o other types accepted, none will be provivded on race day. You may share a can amongst your groupSlide14

Battery Vs. Solar
Be sure to test out your car with the solar panel. You will need to attach the solar panel to your motor with the guide wires. If your car runs backwards, switch the wires around. If your car works on battery but not on solar, look for this – when you pick the car up do the wheels move but when you put it down the car doesn’t budge? This means you don’t have the right gear ratio. Try using a different combination of gears to get the car moving. It may take several tries, don’t get discouraged! Try, try, try again!Slide19
Prototypes and Testing
Use this space to explain any issues or problems you had to deal with when testing your model. Also discuss solutions to those problems. Include pictures or videos if possible. Model VersionDid it work with the battery?Did
it work on just solar?
