This week i have learned that there are multiple types of algae. I also learned that only specific type can survive in different water types. Different algae such as Batrachospermum and Euglena help determine clean and polluted water. Algae such as Batrachospermum  can only survive in clean water while Euglena can survive in heavily polluted water.



Anabaena
1.Odor resembles that found in pig pens.
2. This algae can fix it's own nitrogen.



Pandorina
1. Has a fishy odor.
2. Occurs in groups of 8, 16, or 32.



Closterium
1. Causes blooms in southern states.
2. Contains gypsum crystals in tips.

To focus on a the high power objective you must first start on the scanning objective. Once there you focus on scanning so that the specimen is clearly visible. After this you want to move up to low power and focus in using the coarse adjustment knob. Once adjusted you can move up to high power. From here you only want to use the fine adjustment knob. To make a wet you want to place a specimen on the slide. Once placed you add a drop of  water. After this hold the cover slip at a 45 degree angle over the slide and drop it. If done correctly there should be no air bubbles. To correctly add dye, add a drop of dye to one side of the slip. Next take a paper towel and place it on the other side of the slip. With the magic of cohesion the towel should absorb water and move the dye under the slip. This lab really helped improve my microscope skills by both helping me be more patient when focusing and helping me prepare slides.

1. There are bewteen 5,000 and 6,000 species of amphibians known today.
2. Amphibians were the first four-limbed vertebrates.
3. Amphibians have simple body structures.
4. Most have life cycles which progress through 3 stages.
5. Amphibians are declining throughout the world.

Amphibians are reliant on water because it is needed for them to survive and their skin releases the water quickly. They are important because the habitat they live in and also we must study them in case of dangerous toxins they release.

Our aquarium is doing great. As for our water test, they remain the same as the week before so still good. Our turtle seems to be enjoying his new home but he keeps trying to swim to other tanks. He does this by attempting to swim through the glass. He has eaten three of our five fish already. The other two seem to be afraid of the turtle. We have made no changes since it seems like none needs to be made.

Watershed - Any area with flowing water which empties into a much larger body of water
We live in the Trinity River watershed. It is important to monitor the quality of this water because we are all going to consume or use it in some way, shape, or form. We may use it to drink, eat, play in, or wash with.

1. Common snapping turtle
2. Chelydra serpentina
3. They have powerful jaws and highly mobile necks and heads. Snapping turtles developed the snapping attack simply because they are too big. They are too big to fully fit in their shell so snapping is their way of a deffensive mechanism. They usually don't bight humans, when confronted they slip into the water.
4.
5.They eat anything they can swallow, which includes fish, frogs, reptiles, birds, and mammals, They are omnivores.
6. In most areas these turtles are hunted for their meat. This is used for turtle soup.
7. I chose the snapping turtle because, well, we have a turtle in our aquarium. Also, i wanted to learn more about my favorite type of turtle.

As of 4/18 our tank is looking good, and now even better after our water test results. Our water finally passed with a 10 on nitrate and 0 on ammonia. We are still addind bacteria to help ammonia levels. Some thing that might of also help was the addition of duckweed and plants to our tank. Hopefully we will soon add our turtle.
