I didnt learn very much on the nature walk because i already knew alot about nature. one thing that i did learn was the name of a tree called autum olive. some things that i did on the nature walk is walk with my partner and show her some different types of plants like milk weed and queen anns lace. i also taught her how to make leaf rubbings. my partner said that she had fun.
my water chemistry test is dissolved oxygen in the water, this relates to my project which is hydrogen power in a couple of ways. one way is that u can use a process call electrolysis which is sending an electric current through water causing the water molecules to split releasing hydrogen and oxygen. another reason it relates is that when ever temps rise due to global warming the amount of oxygen in the air decreases causing organisms that live in the water to die, and if we stop using fossil fuels and use more hydrogen power this will stop happening.
right now are project is going good we know pretty much exactly what we need to do to complete it we just have to get some supplies such as magnesium and all of the electrical supplies that we need to get to complete the circuit that we have to make to convert DC power into usable AC power.
my role in the project is to find out about converting our combustion motor to run on propane and to get it running and figure out the reaction to use to make hydrogen.

my footprint
www.mycarbonfootprint.org
this site was ok for me but not good for little kids because it asks for information that most kids wouldn't know. my footprint was 8.26.
three ways i can reduce my footprint are unplug charges when not in use, more efficient lightbulbs and ride my bike when i can instead of a car.
three ways that the school can reduce their footprint are use hydrogen generators, use computers instead of paper in classes, and use solar panels as a source on energy.
three ways that the community could reduce their footprint are by uses wind turbines to power businesses, build a hydroelectric plant and more bike lanes to encourage people to ride bikes instead of driving cars.
for my action prject my group and i are going to creat hydrogen using a chemical reaction and use it to power a small engine. this relates to reducing our footprint because hdrogen burns very clean and does not have the harmful effects on the environment that CO2 does. hydrogen can also be used to power many thing suck as cars or heaters or anything that runs on propane gas.

post #1
i dont know very much about technology or the internet so there a lot of things that i can learn. one things that i would like to learn is how data is sent in the the internet. i also would like to learn how cell phones can send and receive messages and calls. another thing i want to learn what kind of technologies there are that can help the environment. another thing that i think would be good to know is how the motors in electric cars function.
in global science this year i would like to learn about the oceans and the life in them and how their ecosystems work. i also want to learn about space like the life cycle of a star. i also want to learn about growing crops and the technologies the go along with it. i also think animals are very interesting and fun to learn about so i would like to learn more about them to. another thing i want to do in global science is do many expirements.
