What I Did.
This Week In Science we had to research about the animals we was going to dissect. Also we dissected the animals that we researched which was a perch, skate, frog, and mouse. Me and my partner Mayra dissected a perch which is also known as a fish. What we did was cut the perch open to find the organisms. What we found was a heart, and probably the liver which im not really sure because when my partner cut the perch open she kind of destroyed the inside parts of a perch.
what I Learned.
I learned that a perch is common name for a fish. A perch is a freshwater gamefish that belongs to a family of percidae. I also learned that the body type of a perch includes a somewhat long, and rounded structure. Also a perch have a rough or ctenoid scaled, meaning that the scale is smooth but is rough which is also going to make it look like skin. A perch is a carnivourous fish that are can be found in ponds, lakes, streams, or rivers.
Structures and Functions
The two animals that were dissected was a skate and a perch. The smilarties between a perch and a skate is that they underwater but diffrent kind of waters. The type of water the skate lives in is a salt water.

TWIS #8
This Week In Science we learned the safety on how to use the scalpel when we start to dissect. Also This Week In Science we did a Dissection of a Craw fish or a Grasshopper. So me and my partner Mayra chose the crawfish which we had to dissect.But it was kind of gross but my partner and I got through it. I also learned what a Dorsel view is which is like a Top view from its back. A Ventral view is a view that you can see from its stomach which is also known as abdomen.
What I Learned.
When my partner Mayra dissected the crawfish I learned that its feature of its body has five legs on each side which it uses to walk around. And I also learned that the yellow stuff that was inside of the crawfish is the liver. When I found out that the yellow stuff that was inside the crawfish was its food that it digested. Crawfishes live in a enviroment that has to deal with water like lakes, rivers, etc.. Also I learned that a crawfish does not have bones.

This Month In Science #7
This month in science we did a project called zoology of the future. In this project we had to get in groups of four to create our fantasy animal. while creating our fantasy animal first we created a power point which included: where it lives, the climate, vegetation, the land form etc... Also in this project we had to pick animals that live in the hot and cold dessert and it had to adapt to its new climate. Doing this project took us like about 3weeks to do.
What I learned was that in the Hot and Cold that the plants of the dry dessert had adapted to the lack of water by using dew for moisture and taking in water through their leaves and stems. I also learned that the desserts take up to 8.6 million square miles ( 22 million square kilometers ) of earth's surface. I also learned that dunes are not only found in hot desserts but it could be found in dry desserts too. But also the dunes are made up of winds causing the sand to pile up.

Cricket Investigation
Testable Question : Do crickets prefer Dark or Light environments ?
Hypothesis: If I give a cricket the option of a dark or light environment. I think it will move to the dark environment because when we had to observe whether crickets prefer wet or dry environments. When Jamie turned the classroom light on, the crickets started to walk around.And then the crickets started to move like crazy.
Background Research: In science our group observed what the crickets where doing when we was doing the wet or dry environments. The things a cricket needs is food

This Week In Science # 6
We did a cricket investigation where we had to write what a cricket needs, like food,water,where they live,and etc... We also had to also ask question like : Do crickets prefer cold or hot weather ? or Do crickets prefer soda or water ? Also this week in science we did a mission challenge about crickets where we had to get in groups and do two sheet packet about whether crickets like wet or dry environments. The last thing we learned was about Dichotomous Keys.
What I learned :
This week I learned what A Dichotomous key is. A dichotomous key means to classify non-living things and livings things by putting them into groups. Also I noticed that Crickets chirp in the morning or afternoon.

This Week In Science #5
What we did in science:
I learned about animal behaviors. And talking about animal behaviors we watched a couple of videos with the class of how animals behave in some ways, like the first video we saw was about a rare owl parrot trying to mate with the scientist. The other one we saw was the monkey trying to make out with a cat. In this unit we are going to learn about how crickets behave.
What I learned :
I learned That animals for some reason act/behave in some sort way. I noticed that when I saw the video about the rare owl parrot he was being violent, rough, agresive, also a slapper, abusive, and playful at the same time. Also I learned that when crickets are kind of jumpy when I observed it with my group.
