Classification Challenge



Kingdom:Animalia (Means it's an animal)
Phylum:Chordata (Means It has a backbone)
Class:Mammalia (Means nurses it's young)
Order:Chiroptera (Whose forelimbs form webbed wings)
Family:Vespertilionidae (The majority of common bats of temperate regions of the world)
Genus:Myotis (A Genus is the hierarchal point in the scientific system for grouping related organisms together)
Species:M. lucifugus (One of the basic units in biological classification)
 My animal is not similar to any animals in my group. In my group there is a squid and a turtle. However my animal is very different from the animals in my group. My animals order is the chiroptera, which means its forelimbs are webbed together. That is a trait my animal only has. My animal is also a mammal unlike any other animal in my group. That is all the differences my animal has.

Crickets Behavior Investigation




                 My testable question is, do crickets prefer wet or dry land? My hypothesis is crickets prefer wet and dry land. I believe this because I observed crickets in a environment that was half dry, half wet. What I saw was that the crickets kept going and staying on the wet land. I also know that some species of crickets dig tunnels when the land is wet. Crickets also like dry land because some crickets dig chambers with a wet chamber, dry chamber and exercise chamber. Crickets also have to be in a dry environment because if their in a humid one they can grow a fungus on their bodies. Crickets need both wet and dry land to survive!                                                                                                                      
          I did a lot of things while observing the cricket. First I made a data table to show the crickets movements. I wanted to see if it preferred wet land over dry land. I drew all of its movements and saw it preferred the wet land. That was the first cricket. The second cricket didn't really move at all it just stayed on the wet land. I took took trials for each of them, and in both trials both crickets stayed on the wet side.                                                                                                                                                                                                                                                                                                              
           While I was observing the two crickets I learned that they both preferred the wet side. I also learned some crickets are more active than others. Another thing I learned is that crickets can only survive in dry weather. So it really surprised me that the crickets preferred the wet side. That is all I learned during my observation of the crickets.

This week in science #6

                 This week in science we did a lot. For example, we made a list from information we got from the internet about crickets. We also wrote a testable question from the information we got. Then we observed the crickets to see if they preferred wet land over dry. While we observed them we were drawing their path to see what type of land they liked better.We then explained to our class what we did. After that we made a dichotomous  key for jelly beans. They gave us a bag of jelly beans and we worked with those.  
This is an example of an dichotomous key
               This week in science we learned many things. For example, I learned that crickets are omnivores. I also learned how they make their chirping sound. They scrape their wing along the surface of their body. Only the men produce this sound. I also learned from observing the crickets that they prefer wet land over dry land. Another thing I learned this week is how a dichotomous key works. A dichotomous is something used to identify things specifically.

This Week In Science #5

              This week in science I've learned a lot. For example, I've learned how different variables affect the distance a rocket goes. Wings in the center of a rocket make it fly better than wings at the bottom of a rocket. I've also learned how animals interact in certain situations. Some animals act aggressive and others docile. The last thing I've learned in this week is the different parts of the crickets.                        

This picture shows crickets from different angles and their labeled body parts

              This week in science I've done many things. For example, we've watched videos of cats fighting, dears and dogs fighting and birds trying to mate with humans. We've also observed crickets in a clear box with food or sometimes paper in it. We took down notes on what we saw and what we we're wondering. After that we drew the crickets from different angles and labeled each part we saw.
