Classification Challenge

this is a Uca pugnax 

Kingdom - Animalia ( means its an animal ). 

Phlyum - Arthropoda ( means its an  invertebrate animal  having an exoskeleton ).

Class - Malacostraca ( the largest of the 6 classes , includes crabs, lobsters , shrimp, etc ). 

Order - Decapoda ( means it has 10 feet ). 

Family - Ocypodidae ( means its in the family of crabs , that includes ghost crabs ).

Genus - Uca ( its a group of over 100 species ).

Species -  ( U. pugnax ) There are man species of Uca , over 100 crabs. 

The other members of my group picked a fish , shrimp and jelly fish. These animals are similar because they all are sea animals , but my animal can be on land. 

My animal is special because one of its claws is bigger than the other giving it a distinct look. There are over 100 species of fiddler crabs. 

Cricket Investigation

   Question : Do crickets prefer light or dark environment's ?
  
  Hypothesis : I think the crickets will like the dark environment ( a cave , toilet roll ) because they seem to like cool weather things. We did a previous experiment on wether they like wet or dry environments , and the crickets liked the wet side better. So i think they will prefer the dark side.

 Background Research : Crickets are omnivorous so they will eat almost anything. They need water , and the need a lot of air so any containers should have holes. Crickets also seem to like wet environments more than dry.

      

                                                                                      
This shows the cricket when we placed it in the tube. The cricket did not seem to like being in the tube , but the cricket was on top of the tube.

       

This picture shows the placement of two crickets. The top pic is the first cricket and the second one is the second cricket. 

My data does not support my hypothesis. I thought that the cricket will like the cool environment , but it always went on top of the tube. So my data shows that the crickets like the light. The cricket crawled out two times when placed inside the tube. So my final conclusion is that the crickets like the light. 

This Week In Science #6

      

  This week in science was very fun. My group and I had to observe crickets , recored data , and we  made a chat about jelly beans. The week started with the crickets. We observe them and their behavior's. Then we recorded it by putting dots on a piece of paper , marking the position of each cricket every 15 minutes. We also tried to group jelly beans using a dichotomous key. We used pictures and descriptions of the jelly beans to group them.

    This week in science i learned many interesting things. I learned how to use a dichotomous key. Its a very good way of grouping animals by species , and then brakes them by using specific features. But in my situation i had to use jelly beans and group the different flavors using the dichotomous key.
      

      
      
  

  

This Week In Science #5

                          



   This week in science , my friends and I shot our paper  rockets. We had three rockets and each of them had there own amount of fins. We wanted to see if the number of fins, affected the flight of the rockets. This week we also observed some crickets. We had to draw 3 pictures of what we saw , and write down some of the crickets behavior. Last we viewed videos all a class on youtube, and we watched how animals  behavior.
    

  
   This week i learned about crickets. I was given a sheet with labeled cricket parts on it. I never knew the names of the cricket body parts , so that was interesting. For example , the body of the cricket is called the abdominal segment , and behind the head is called the thorax.

this Week In Science #4

This week in science i did a document with my group. We all were assigned a part in the document. My part was to record the data of the cups , and put them on a graph. I had to average the growth with the help of a one of my group members, Then i had to to a experimental set up, where i had to explain how my group and I set up the cups .


This week in science i learned how to put data on a chart. David taught me how to set up the chart. Then he taught me how to copy the graph to my group document . The chart showed the growth of my plants over time .

  

This Week In Science #3

                                        Here is a example of the bar graph my group & I did .

This week in science i DID  two experiments . I did a experiment with jaime , where we gave directions & she had to follow . Her goal was to make a perfect peanut butter sandwich . Then we did another experiment .  Every group had a different task . My group and I had to make a graph about the months every student was in .

This week i LEARNED a few things . From the peanut butter jelly experiment i learned that if you give directions they have to be really specific , because then the person wont know how to do it . I also learned that my hypothesis was wrong . I though that the seed in the bottom  of the cup will grow slow but its the fastest & biggest so far .

This week in science #2

                                                          A picture of Brassica rapa

This week in science i learned many interesting things . I learned all about Brassica rapa which is a type of seed . One of the cool things about this seed is that its lifespan is about a month . It reaches full growth , & they are made to grow fast . Then i was given a task to write a few fact about the Brassica rapa by searching it online . I find this seed very interesting & its in the mustard family .

 Now my group & I are going to try a experiment with the brassica rapa . Our question is - Does the depth of the the seed affect the growth ? So we put seeds in 3 different cups at different depths to see if the depth does affect the growth . We also had a little fun with "poppers" which are little plastic toys that use air suction to pop of the table . We used these for a experiment .
