Classification Challenge

This is a Squalus Acutirostris

                Kingdom: Animalia(means it's an animal)
                Phylum: Chordata( means it has a backbone)
               Class: Chondrichthyes(means are jawed fish with paired fins)
               Order:Squaliformes(is an order of sharks that includes about 97 species in seven families)
               Family:Squalidae(means the family of dogfish sharks)
              Genus:Squalus(means is a large genus of dogfish sharks)
              Species:Acutirostris(is a dogfish shark of the family squalidae) 




     A dogfish or a Squalus Actirostris are harmless. They are found in the Atlantic, Pacific, and Indian oceans. Also from tropical equatorial climates to the Arctic and antarctic. They are small to medium sized sharks (48 centimeters 19in) to 16 meters or (5.2 ft) in adult body length. They have 2 dorsal fins with smooth spines. They have no anal fins. They have or possess venom and it coats the dorsal spines but is mildly toxic to humans. They are carnivores and prey upon organisms smaller than themselves.    

                    

cricket investigation

Question: Do crickets prefer light or dark environments?

Hypothesis: If I put a dark area in the tank. Then I think the cricket will be in that area. Because that's where they like to be the most.
   

Background Research: Crickets can live in different places. Some habitats are like meadows, trees, forests, lawns, and houses. Crickets are important in the ecosystem. Because they can breakdown plant material. Things they eat is grass, fruits, seedling plants, fungi, and meat. I also found out that male crickets make the sound. I also found out that small owls, spiders, birds, mice, shrews, snakes, frogs, and opossums can eat crickets.

The cricket is on top of the tube which the inside is dark.

 

This is the Data picture.

 The data picture mostly shows that the cricket is on top of the tube and again inside is dark.

What I did: First I had to pick one question from I think four questions as a group. And then with that question I had to a hypothesis with the if, then, and because format. With the research I did about crickets and recorded in my notebook I just had to put it in a paragraph. I took a picture of the cricket in the tank with the dark area in it. i also took a picture of how I collected data and that's it.

What I learned: Doing this I learned that somethings can easy and some can be hard to do. Because you not make the cricket do something you want them to do. I saw that the cricket liked to be on top of the tube which inside is dark. The cricket was in the dark area but not for a long time. Not a long time to convince me they like the dark. And that show that my hypothesis is wrong I was wrong because I said that it will be or stay in the dark area.

This Week In Science #6

   This week in science I did some research on crickets. It was based on what are there needs. Like what kind of food they eat,how do they live thing like that. And then I made testable questions or you could of pick one that the class made. Finally I did Dichotomous keys one of them was a list style and the other one is flow chart style. Based on jelly belly I think because they were different color one and some of them had spots.

These are jelly belly's and as you can see they come in different colors and some with spots.

  This week in science I learned that there's different kinds of crickets. And that some of them have different things on them like one has wings and another don't have wings. Also I learned more about Dichotomous keys. Because last year in the 8th grade I did something like the list style.So that's why I got fast. And it was with different animals I did it with last year.

This week in science #5

  This week in science,the first thing I did was finish my Rocket conclusion. Then I went in a group to finish my conclusion. I skip a page for a cover page for the new unit. Then the best part is observing crickets and some of them were dead and with one leg missing. Also I look at different videos about animals and there behavior. And I took notes of the animals and there behavior.
  This week in science I learned that observing animals could be a bad and a good thing. Because they may do something funny or something horrible. And I learned that drawing about what you are observing could be a good thing in the future. Also I want to know why the crickets make the nose they make.

    The cat is on the sofa playing around. Putting its paw in the sides and is really funny and that's why I put it up.

This Week In Science #4

  This week in science we as a class started to pick who was going to do what job in the plant investigation. And when was the job going to be done like in block 1 or in block 2. My job was the results and i had to to make a date table and a graph showing the growth of the plant based on the amount of soil i put in each cup. Also I was not done the first day or in block 1 so in block 2 I showed what I had done to David the he fixed it up.
  This week in science i learned important things like making data tables and graphing things faster and easier. Also i learned that is important to keep in mind what as been teached. One them is like the hypothisis. And i learned that in order to get a job done every boby in the group have to get a job because if not is never going to be done.

This Week in Science #3

   This week in science I did half a page about what we need to know about the the plant investigation. I did a hypothesis work sheet tape in. I did a procedure about how to make a peanut butter and jelly sandwich. Had to it twice because the first time i notice that it didn't turn out right and did the other one in more detail. And write a procedure for gathering data. Finally i had a mission to do and had to do a graph.
    This week in science i learned what  is a independent and a dependent variable. And i learned how to write a hypothesis. Also with a question or testable question i can turn it into a hypothesis using the if...,then..., and because... format. I can turn a hypothesis in to a question. And that when you going to write a procedure it's very important to write it in detail. Because you want some one else to do what you did.

    
    

this week in science #2

    This week I started out by writing my own testable question and that means a question that can be answered using observation.I was introduce to poppers and of course they make a pop sound.I had to write about a plant called BrassicaRapa based on the plant i did a t chart and wrote facts i learned and
what am wondering and do a summary.Then after that we planted the brassica rapa based on the testable question we picked as a group.
     What I learned this week is what was a testable question is. The poppers come in different color,sizes, some go higher than others. I learned about variables(what you an change) and dependent variables(things you can measure. I learned that the brassica rapa does his life cycle in 14 days.
