This week in science #9

This week in science we dissected animals , my group dissected a perch and a skate. we had to sketch out the animals from different angles from its Dorsal View and Ventral View. then we had to open photo booth and take pictures of it and upload them to google doc's. then we cut the perch into a rectatangle shape and we had to first locate the gill bladder and liver than take them out. with the skate we had to cut a circle in the center of it and look inside.

Earlier this week in science we learned how to use the utensils such as the scapel and the scissors designed espeically for cutting flesh. We also learned at is the Dorsal View.
Ventral View. i learned how to identify if a perch or a skate is male or female. My perch was a female perch and i learned that she was pregnant but most people take that out and make caviar out. in the skate we cut its intestines and we found that the skate had ate a sand crab. how come when my team and i removed its lungs and lever we found some oil behind it.

The two animals i dissected were the skate and the perch are similar because they are both marine animals but there body shape are very different. Both of the animals skin where very tough like the skate had spikes on them and the perch had a lot of scales on it. they both carried alot of water inside of there bodies.Another similarity

the perch has fins and the skate has fins too but the difference is that the skates are bigger.

This month in science #7

  This month in science my group and i made different slides on the tropical rain forest. We did screen casting. We had to make an agreement with all the group members on what to do when some ones absent or is not doing what the have to do right, i am glad we stuck to it. We all had to do research on google  about the tropical rain forest now and the animals that live there. Then, David and Jamie sent us a letter saying that our biome turned into the ocean 1,000 years later. So what we had to do is transform our pervious animal into an animal that would survive in that enviorment.



  This month in science I learned about a beautiful butterfly that lives in the tropical rain forest named blue morpho butterfly. i learned that my group works very well together. I also learned about the panthera tigris and how its prey is a monkey. I figured how to make one organism out of plenty. I also learned how to make a screen casting video.

Cricket Investigation

Question : Do crickets prefer fruit or vegetable ?

Hypothesis : if we put fruit on one side of the tank and vegetable on the other , i believe they would prefer fruit because david just put an apple in their tank so if they liked vegetables better he would of put a piece of lettuce or something in the tank.

   On one side we put celery and on the other side we put apple.

This Week In Science #6

      This week in science I have observed cricket behavior. We used four methods to see if crickets prefer damp or dry better. we had two crickets inside one tank, the whole tank had paper towels. In one side the paper towel was damp and on the other it was dry. the crickets stayed in the dry side most of the time. Then my group and i took off the lid. Afterward the crickets started to become more active. One of the crickets went on the damp side and then back to the dry side and both crickets began to fight. 

      Towards the end of the week my group and I had a mission challenge. We learned how to use dichotomous  keys. The challenge was to use different methods to classify jelly beans and see which method works best. To help us learn how to use dichotomous keys David showed us by using shoes from different students in our class room.

This week in science 5

   
        The video above is a video i found on youtube of this fascinating creature found in japan. i found this animal to be strange. 



 
This week in science my group and i have been observing animal behavior. we have been watching youtube videos of strange animal behavior it was actually interesting how animals behave way differently than humans act.  yesterday in class we were observing actual cickets. they barely were moving , the crickets were hidding the the loose leaft. Afterwards i saw a baby cricket come out of the paper and started eating the piece of apple that was there.
