In this project, you will design, construct, test, and modify a device that releases thermal energy by chemical processes. You will be provided specific materials by your instructor, and will use these

materials to design a device that releases energy to the environment. Next, you will build the device and

test it by gathering temperature data. Finally, you will use your data to evaluate the design and decide

how to improve your device.

1. loamy sand is about 80% sand with 10% clay and defined mostly by sand particles with some clay to provide structure and fertility. the sand particles are easily visible and the soil holds structure but breaks apart easily.

2. scott sand can improve his soil quality by incorporating more silt and organic matter into the soil. peat moss and organic matter can also be incorporated.

its temperature is increasing. this causes molecular vibrations to increase.
