Summary: Raising money for charity can really make you feel good. The Marine Mammal Foundation helps raise money to raise protection for endangered marine mammals. The charity saves and rescues marine mammals for many different reasons such as human activity: net and fishing line entanglements, gun shots, and more. To help raise money for this worthy charity, we sold cake pops at the charity fair. If we sell these items for $1 each, we would make $.75 per cake pop in profit. Transporting all the materials for the cake pops with the original materials creates 4317203302.5 g of CO2. If we could find a way to source our material all from California, that number would go down a bunch. I really liked the charity fair! Backward-Looking:  Have you done a similar kind of work in the past (earlier in the year or in a previous grade; in school or out of school)? I did the charity fair last year as well as this year. There were some differences and similarities. Last year, we did...

Image - Summary -  This week I learned about Soil. There are two types of soil treatments - plant and trench. Trench makes the soil shape like a staircase while plant keeps it as a firm,flat surface as the plant roots hold the figure of soil together. There are  also different soil types. A few types of soil are silt, sand, and a mixture of both. We used virtual explorations to learn about soil texture and type, and more. I also learned about carbon footprints. A carbon footprint is the amount of carbon and other compounds let out due to the utilization of fossil fuels. Soil has different layers called horizons. Topsoil is the top layer aka the A horizon, and is made up of decomposed materials. The next layer is the subsoil aka the B horizon, and it is  made up of clay, mineral deposits, and less decomposed materials. The layer below is the C horizon. It is made up of a little unbroken rock and very little decomposed materials is in this layer. SP5 - I used math ...
