We charged a drained battery for 3 min. And hooked a lightbulb to it. The lightbulb used heat and light energy. The light stayed lit for about 12 min. Then we used another drained battery and charged it for the same amount of time we hooked it to a motor which used mechanical energy. The battery only stayed on for about 7 min. The motor used more energy. Batteries give off electrical energy. That is what turns things on. Batteries have stored chemical energy that help the battery work and give things an electrical charge.

A: yes, because to turn on a light it uses energy caused by an electrical charge and our light did turn on, B:describe what makes up a battery. B:a battery needs positive and negative energy to give things an electrical charge. C:what do you conclude from your observations of the zinc-copper strips you placed in the copper sulfate solution ? C:the zinc was the positive energy and the copper was the negative energy, and them put together into the acid made a battery. D:what happened to your lightbulb after you removed the assembly from the solution? How could you explain to someone what happened? D:the light slowly faded and then finally turned off. E: In these activities you probably noticed that the bulb was not very bright. What could you do to make the bulb glow more brightly? E:well, I think it depends if you have a lightbulb with larger watts and a larger zinc and copper strip. If it had that I think it would be brighter.

What thats means is at the beginning of the year we were split up into groups. All of our jobs were something we gould test in Chimacum creek. There was nitrates, ammonia, P.H. (posotive hydrogen)  flow rate, D.O. (which is disolved oxygen) and tempeature. In our classroom we have been presentating to the class what our job is and what it means. I learned soooo much!    Over all I think chimacum creek did fantastic. Now heres my proof. With the bugs in our creek we got 21 points. Now that could be better but overall that isnt that bad of a score.    Our average for water temperature was 33.5 degrees f. That is a pretty good average for Chimacum creek. At this temperature the salmon and other life is comfortable and algae wont over grow. Temperature is very important because without a temperature range eventually everything would die.     The average for P.H. (posotive hydrogen) was 6.3. This average for the creek is pretty good. P.H. is a balance of positive hydrogen ions and negative hydroxide ions. It tells how actitic the water is. Fish need a balance of alkaline and acid.    D.O. is  dissolved oxygen. Our average is 9.16mg/L. This average is fantastic for our creek. It is very comfortable for the fish. Without dissolved oxygen the fish wouldnt live. Dissolved oxygen is the only soure of oxygen they have.    For ammonia the average was 2.828 mg/L. Now if that was true that would be very bad. But we believe that we had a probe that did not work. So we dont know what the average was but we know it  for sure wasnt 2.828mg/L. Ammonia is a chemical that is used in cleaning agents. it is colorless and will kill the fish. The average for nitrates was 0.3. That is really good!     Nitrates is in fertilizers. Our average was 0.38mg/L. For our creek 0.38mg/L is very good. This means that the farmers this year did an outstanding job!   Our average for flow rate was 1.3459 cubic meters per secnd. This is very good for the salmon. Flow rate is the amount and speed of the water that passes by per second.    Overall Chimacum creek is pretty healthy. Everything was about where it should be.  RECCOMENDATIONS TO KEEP THE REEK CLEAN: 1. Dont litter. 2. Keep your gutters and drains clean because when garbage and other stuff goes down gutters and drains it ends up in lakes and rivers and oceans. 3.Keep fertalizers and other products away from the creek.

 Article posted January 27, 2012 at 04:33 PM GMT • comment (2) • Reads 1109 Yesterday all of the six grade students went to Snow Creek in Discovery Bay. We planted tons of trees. The reason we planted trees is because 1. They are good for the environment. 2. because there arent very many trees out there and the trees that there are are old so now that we planted more trees when the older trees fall over, there will be more trees to surround the creek. Now you may be thinking that trees dont have any effect on the creek but the truth is they do. they affect the creek a lot. They do many things to help the creek. They prevent the creek from eroding (which means dirt falling into the creek and making it smaller or blocking it.) The trees also provide shade that keeps the water cool. there are many other ways that the trees help the environment. I probably could think of many other ways how trees help. The list just goes on and on. Article posted January 27, 2012 at 04:33 PM GMT • comment (2) • Reads 1109

Chimacum creek scored 21 points. 23 points means that the creek is very healthy. We aren't quite there but we came close. We got 21 because some of the bugs we found were very tolerant. Tolerant isnt always good. Tolerant means that the bugs in the water can handle water pollution. Too much water pollution could hurt our salmon. Group one, intolerant, were worth four points, group two, tolerant, were worth three points, group three, really tolerant, was worth two points, group four, extremely tolerant, was worth one point. With all of the bugs we scored a total of 21 points. Now most people would be wondering why yellow jacket creek got a better score than chimacum creek. The reason is that their bugs were less tolerant. And the reason is because less tolerant bugs means that they can't stand water pollution. Yellow jacket creek had less tolerant bugs and less tolerant scores more points. Something that might have helped chimacum get a better score is if there wasn't as much civilization by our creek.

 Article posted October 18, 2011 at 04:34 PM GMT • comment • Reads 1929 Water pollution is one thing that this world needs to improve on. Water pollution is a problem that is ruining out water source. In this article I will be answering the following questions. What is water pollution? Whatwater types of water pollution? What is the outcome? What are solutions? And how can we prevent water pollution? Water pollution can come from a number of sources. If the pollution comes from a single source such a an oil spill, it is called point-source pollution. If the pollution comes from many sources, it is called non point-source pollution. There are manso types of water pollution. One example is, oxygen depleting. Oxygen depleting is a substance in the water that depletes the oxygen. Some more examples are ground water nutrients, microbiological, suspended matter, chemicals and surface pollution. Ground water nutrients some ground water nutrients nitrogen and phosphorus. If too much of these, water can grow algae and become clowdy if too much algae grows it is called algal bloom. Microbiological is small life form such a parasites that can only be seen under a microscope. Suspended matter is floating objects that don't belong such a fecal matter or litter. Chemicals are material involving changes in atoms or molecules such as oil or pesticides. Surface pollution is pollution such as plastic bags that float at the surface polluting water. There are many consequenses of water pollution,but some of the main ones are problems,less fish, unhealthy water plus a polluted earth.Water pollution hurts our water resourses, such as lakes, rivers and oceans and our drinking water. It is a big problem and a global concern. Many diseases, health problems and even deaths have been tied to water pollution. The contamination starts with humans and ends with death. To improve our water we can pick up litter litter and not have farms or pipes so close to creeks, lakes and oceans. We also could work together to clean up the oil. To prevent water pollution we can build stronger pipes, recycle, and not dump sewage into the water. Article posted October 18, 2011 at 04:34 PM GMT • comment • Reads 1929
 Article posted October 3, 2011 at 04:31 PM GMT • comment (2) • Reads 2147 I think Mt. St. Helens might be able to rebuild itself depending on if erupts. If it keeps on erupting it won't get a chance to rebuild. If it doesn't erupt it will take about 140.5 years to go back to it's normal state. The reason it will take so long to rebuild is because it has to rebuild 4,213 feet of rock. You are probably thinking how could Mt. St. Helens rebuild itself? It grows over 1 inch every day. That's 300 feet every 10 years. That's a lot! Article posted October 3, 2011 at 04:31 PM GMT • comment (2) • Reads 2147
