Our experiment:) -- 05-07-12

2012-05-07T13:12:29-05:00

My group is using 2 containers with dirt in them with 3 dixie cups in each all colored a different color. Then we will put a snail in each container and see what color each snail goes to see what colors snails are attracted to. Or if snails can even see in color. I think the snails will go to the brighter colors because i think they will stand out to the snails more. I will make another blog with the results! Check it out:)

Snails!!!! -- 05-02-12

2012-05-02T12:49:23-05:00

What I know about the snail?

~They are all the same sex.
~They leave a slimy trail.
~They have a shell.
~They all vary in sizes and color.

What I want to know about the snail?

Why are snails so slimy?
Why do snails only eat plants?
Can snails live without their shell?
Do snails have feet?
Why do people eat those nasty things!?!?

My Science Experiment:) -- 04-18-12

2012-04-18T13:09:28-05:00

So for the past couple weeks,my group and i have been trying to grow Lima beans but also get a lot of interesting facts about them. Our Lima beans did not grow they ended up splitting in half and molding because we did not control how much water was entering our container of dirt so they pretty much flooded because we had them on top of the roof on the building out side. Plus we had very little sunlight for the Lima beans. But when we presented we had a Prezi for our experiment and what we did wrong. On our i-movie we had many interesting facts about Lima beans and the different types such as bush Lima beans and pole Lima beans. Lima beans are also known as chad and butter beans. This is what are experiment turned out to be.

So... me and my group decided to swab the door handle, lunchroom table, toilet seat, and the locker room locker for bacteria. We made a bad mistake when we put the bacteria in the container because we broke the agar that was at the bottom of the container. it broke in all the sections except for the toilet seat section. 24hrs later after we stuck the petrie dish in the incubator we found only one small speck in the toilet seat section. we believe that it didn't grow anywhere else because we broke the agar which was the food, which made it so the bacteria couldn't eat..we found out that bacteria cant feed of plastic...that is all for are observation:)

Paramecia -- 12-13-11

2011-12-13T14:28:53-05:00

I believe that Paramecia are single celled organisms that can live on their own without having to be attached to something to survive or get life support off of another living organism. Paramecia are very cool! They are very interesting to look at under the microscope because you can see right through them, they look like very little stretched out ovals. The Paramecia move by using their hair like arms to move through their environment. When my group put red food dye in the tray that held them you could watch the Paramecia eat it so it turned the inside of the Paramecia red. The liquid was red to be able to tell if the Paramecia could eat on their own. This is what I've learned so far about Paramecia.

feather under the microscope -- 11-18-11

2011-11-18T13:47:53-05:00

Me and my group were experimenting with the microscope...our science teacher mr. G gave us a feather to study as we looked at the feather under the 10x zoom each strand of the feather was like it had been curled into very small microscopic curls it is very interesting to see all the details and characteristics of a feather under a microscope. What things did u guys see when u looked at the feather?

Yeast and monster energy -- 11-16-11

2011-11-16T13:51:53-05:00

When i did a experiment with trying to grow yeast in a yellow monster energy drink i discovered that the yeast seperated the energy drink up! I couldn't really figure out why it seperated...Does anyone know or have any idea why it would have seperated?

Experimenting with yeast -- 11-03-11

2011-11-03T13:58:46-05:00

First me and my partner Hanah brought in a bottle of apple juice, monster energy drink, sugar water, salt water, and cola we added the yeast and after a day mostly all the yeast settled to the bottom but we noticed that in the cola test tube the yeast had rose to the surface and created a brown circle around the top they alsmelt kind of like carbonated soda

!!!!!!!!!!!!!!science about a straw!!!!!!!!!!!!! -- 06-02-10

2010-06-02T11:48:45-05:00

over the weekend i was trying to make a experiment well i finally figured out a experiment it was a straw experiement when you stick your straw in your cup of soda and then you bend your straw lower than the height of your drink the staw will fill up with soda all the way up to the bend and the the straw holds the soda there intell u you unfold the straw.

!!!!!!!!!elastic force!!!!!!!!! -- 05-05-10

2010-05-05T11:54:45-05:00

the elastic force of a rubber band is the force that is coming off the rubber band as you pull the rubber band the force increases as the rubber band goes ferther. i learned that a elastic is a force when you are pulling something yourself and your thing is pulling further to make your force get stronger or increase.

energy -- 04-26-10

2010-04-26T12:01:44-05:00

The energy changes from stored energy to chemical energy when the energy goes through the wire in to the thing you are powering and out the other wire back into the battery it is then called chemical energy this is what makes the battery go dead after all the stored energys gone. When you charge a battery it puts more stored energy in your battery then your battery will be able to be used again if your battery is rechargeable. if your battery is not rechargeable your battery is know useless. When you use a battery it goes from stored enegy in the battery to chemical energy.

all you need to know about energy!!!! -- 04-23-10

2010-04-23T12:24:54-05:00

Alessandro volta made the first battery in the 1800's. his batterys weren't practical because they were to big they were the size of a classroom. so he decided to use his batterys and make another branch of science called electrochemistry. some archaeologists believe that alessandro did not make the first battery because they found 3000 year old batterys made in baghdad that were made of clay.there is one thing that batterya have in common which is they all have stored chemical energy. that is ready to be turned into electrical energy. some batterys can hold more energy bacause of there capacity and it also depend on what the electodes and electrolytes are made of. there are two mane types of batterys which are dry cell and wet cell. a wet cell is like a car battery that is 12 volt to power bigger things such as cars and tractors and ect. a dry cell battery has a interior of a zinc-carbon dry cell. it is filled with lots of electrolyets (mno2) which is a type of paste. this battery powers little things like flashlight toys and ect. !!!!!!!!!!!!!THIS CONCLUDES MY BLOG HOPE YOU ENJOYED AND LEARNED LOTS!!!!!!!!!!!

Freshwater pollution
By: Haley, Hanah, And Kate.

This pamphlet will provide you with information about how fresh water pollution can be caused and prevented.
What is water pollution?

A. Fresh water pollution is when there is runoff or people dump trash or oil into the water. The water is then polluted.

What are some of the sources of pollution?

A. Oil is one source of pollution, and from the ships dumping large amounts of waste into the ocean is another.

What are some of the consequences of water pollution?

A. Animals from the ocean and land that drink the water get sick and could die. They die from people dumping waste in the water.

What can be done to improve the quality of water after it has been polluted?

A. Pick up trash around the water and recycle properly. Get people educated about water pollution.

What are some actions that can be taken to help prevent water from being polluted?

A. Recycle properly. And add in less household cleaners and chemicals. Don’t throw trash from your boat into the water.

What are nitrates and how do they get in are water?

A. Nitrate is a natural compound present in all eco system. It is one of the chemicals essential to plant life but too much can be a problem for plants and animals. It is also a component of chemical and mature based fertilizer.
Nitrates can enter watercourses and ponds from sources such as areas of high fertilizer use, livestock feedlots and pastures, and sewage treatment areas.

What effects do high nitrates levels have on people?

A. Well it caused blue baby syndrome that put big effect on people.
.

What is considered to be the safe level for nitrates in drinking water?

A. Under 10 mg /l no.

What should a person do if there are high nitrates in their water supply?

A. If you are pregnant try to avoid drinking water on a daily basis from that source. You should call your water supply company right away.

What can be done to prevent nitrates from entering our water supply?

A. Reduce the high fertilization dig tile drains deeper in the ground. This will prevent nitrates in your water.

What are point and non point sources of pollution and what are the differences between the two?

A. A point source of pollution is when you know what’s causing it. A non point source is when you don’t know what causing it. The difference is that one can be traced and one can’t.

We hope that you try and get people educated about fresh water pollution because it is becoming a huge problem.
