This week in Science #9
This week in science we did some sugar honey ice tea! We first brain stormed the creatures that we were going to dissect. They were the mouse, the frog, a skate and a perch. Then we observed the two animals that we were willing to dissect. My group chose the skate and the perch. We drew dorsal and ventral views of the animal we were going to do. Later on in the week my group and I dissected the skate and we found many parts like the stomach, large intestine and liver. I was disgusted and fascinated at the time. But the skin of the skate is very thick and was thorny because of its spikes in certain ares like the tail. You can see this in the picture above.
This week in science I learned weird things. I learned that the skate has very thick skin and if its a male it has claspers. I learned that frogs and mice are more like humans than the skate and perch. I learned that female perch produce hundreds of eggs in one laying (called caviar). I learned some organisms are harder to dissect because of their skin like the frogs skin is way thinner than the mouses because the mouse has a lot of fur which makes it harder to dissect. Lastly I learned that skates have a whole lot of water in them still after they are dead.
Well my group dissected the skate and my "table mate" dissected the perch. These two animals are similar because both are harder to dissect. The perch does not have spikes or thorns on its body but the skate does for protection purposes. The perch has scales and fins the skate doesn't it has a smooth skin. The skate has a long tail with spikes to wave off predators. And lastly the skate has its mouth on the bottom but the perch has its mouth in the front.

This Week In Science #8
Above is the dorsal view
Below is the side view
This week in science we did some pretty disgusting stuff. We dissected an earth worm, a craw fish, and a giant cricket. My group took pictures and drew pictures of the creatures we dissected, which was the craw fish. We saw the heart of the craw fish and the gills that were inside of the craw fish's tough armored skin. We also took dorsal and side photos of the fish before getting crazy with the dissecting. We also used scalpel and the scissor for the first time during a dissection with a creature.
This week in science I learned how to dissect different species such as the earth worm, a cray fish and a giant cricket. I also learned how to hold and use the scalpel and scissor the correct and appropriate way. I learned that I like dissecting things. I didn't know cray fish had gills inside their of their bodies unlike fish, who have it outside their bodies. I learned that Angela likes to play with the disgusting earth worms. And lastly I learned the different views of the dissections. A couple are the proximal view, dorsal view and the ventral view.

This month in science
This month in science we did a project. We had to make a power point video with our group on the background that we chose to do. We had to choose an animal that lived in the environment and what it eats and etc. During this project we also had to vocally record what was on our power point (vegetation, location, climate, and landforms). My group actually chose the desert and and we chose desert animals, and described the climate. I chose the desert bighorn sheep. I did one slide and it was beautiful, but my recording part was horrible.
This month in science I learned how to create a great power point for my science project. I also learned how to put a picture as the background of the slide. I learned that speaking over laptop is not my strong suit and that I work slowly with a group. I learned that the desert has sheep, and the desert bighorn sheep eats bobcats, mountain lions, coyotes, golden eagles, and wolves. I learned that it rains in the desert but very rarely. And lastly I learned that I should do better in science class because I have a C+.

Classification Challenges.
Dogfish Pup:
-Can hunt alone in groups.
-Eat small fish, squid, and crustaceans.
-Has a string jaw for crushing shells and has small but sharp teeth.
-Is a bottom dweller but needs to be in temperatures of 45 to 59 degrees.
-Has a sharp spine in front of the dorsal fin (can be poisonous).

Cricket investigation
Background Research:
Female crickets have a ovipositor in the rear. Crickets are omnivores and feed on organic materials. They live under rocks and logs in meadows (many are nocturnal). Crickets are eaten by spiders, some wasps, ground beetles, small rodents, and lizards. They are either brown or black. They are an important food source for other animals.
Question:
Do crickets prefer light or dark?
Hypothesis:
If we give crickets the choice of light or dark
then we think the crickets will prefer dark
because crickets aren't seen or heard in the light as much as the dark.
Experimental setup:
The first time we put a cricket in the tank the cricket was in there for a long period of time. So then we got more and all of them were also in there for a long time. Actually 20 minutes.
Mini Conclusion:
I learned that crickets like the dark more than the light because they spent a long time inside the dark tube than outside in the light.

This Week in Science #6
This week in science we research crickets body parts, what they eat, who eats them and more. After we did our cricket investigation we did a data day for crickets. We did also do a activity for dichotomous keys involving classifying shoes into there own categories. We made dichotomous charts and lists for jelly bellies to see how we classified them and decided which flavor was which by observing them (in spots and color). While we were in groups we had to make a dichotomous chart and show how we did it and which style do we prefer ( chart or list).And we had to do our cover page for our new quarter, which had to be colored from end to end and had to have animals on it. We also drew how the crickets looked from the front, side, and top view.
This week in science we learned how to classify things by using a dichotomous keys and lists. We also learned how to read them. I learned that crickets are obviously more active with the top of the lids off.
I learned that there are also of kinds of jelly bellies and flavors. I also learned that crickets prefer wet environments rather than dry spots; because our research shows that crickets sit on wet spots for a longer period of time than dry environments.
