This is my fifth science project. It is about light and prisms. Enjoy!

Objective: To observe properties of light. 
Procedure: 
1. Get a prism and some cardboard.
2. Set the prism on the cardboard and put it in a lit window. Record observations.
3. Go into a dark room.
4. Shine a light on the prism and record your observations.
Data:
Sunlight:
I see the colors red, orange, yellow, green, blue, indigo, violet, and some undefined colors.
LED flashlight:
The light is less pure than than the sunlight. I see the colors red, orange, tan, and blue.


Iridescent flashlight:


I see the colors redorange, yellow, and tan.


Xenon flashlight:


I see the colors red, yellowgreenblue, and violet.


The sunlight was the most spectacular and the other weren't as bright.






This is my fourth science project. It is about insulators, resistors, and conductors. Enjoy!

Purpose: To discover good conductors and insulators.
Procedure:
1. Get assorted objects.
2. Run a current through the objects. 
3. See how well the current goes through each.
Data:

Conclusion: The best conductor was the wire, the best insulator was unknown and the best resistor was the skin. The project went well and without a problem. At the start, we we got the answers wrong often, but at the end we were getting them right often.

This is my third experiment and it is about chemical energy. Enjoy!


Objective: To make a battery from lemons to test a property of chemical energy.
Procedure:
1. Connect three lemons together with copper and zinc wires and also screws and pennies.
2. Do not connect the last screw and penny together. Instead, connect to a voltage meter or LED to test voltage.
3. How much voltage do the lemons produce? 
Data:
It works!
Conclusion: We had some problems with this project. We couldn't get the penny in, and the LED needed more power than we thought. Other than that, the experiment went well and we got the answers we wanted.

Here is my second science project. See what you think. Enjoy!

Purpose: To observe how objects attract each other through static electricity.
Procedure:
1. Blow up two balloons. 
2. Set up a control balloon.
3. Test the control balloon.
4. Test the other balloon by rubbing it on the surfaces required.
Dependent Variable: Attractive force, length of tim balloon sticks.
Independent Variable: Things on left of chart.
Standard Variable: Balloon, Humidity.
Data:



Conclusion: The balloon stuck to most of the objects, but it ultimately depended upon the material we were rubbing it with. The balloon, the hair, the silk, the wool, the cotton, and the dog’s hair are insulators. The transfer of electrons happens more easily between two insulators, meaning an imbalance of charge is likely to occur. This imbalance causes the negative charge on the balloon to be drawn to the positive charge on the other surfaces.

The Groundhog

Today is groundhog's day, so how about a poem about groundhogs? Enjoy!

A fat groundhog fell over feet,
Tumbled down garden paths,
Carrots rose, trees with orange toes,
The groundhog cleared large swaths.
