TWIS #7

What I DID: This week in science  we worked on are zoology of the future project. We had to create are animals that we think could adapt in an eviorment in that is different from the one they lived in previously. First we choose any animal that lived in are first biome . I choose a seal. Then when it got moved from a tundra to tropical rainforest. I gave it some characterics of animals that live in rainforest to help it adapt.
 What I LEARNED:A tropical rainforest is an ecosystem type that occurs roughly within the latitudes 28 degrees north or south of the equator (in the equatorial zone between the Tropic of Cancer and Tropic of Capricorn). This ecosystem experiences high average temperatures and a significant amount of rainfall.

TWIS #8

This week in science we dissected a crayfish and crickets. What I did was dissect a cricket, before dissecting a cricket I took a dorsal view photo of the crickets body. I labeled the abdomen where i dissected the cricket down the middle. I also did a lot of research on crickets to find out their internal anatomy to know what things to look for when i dissected it That way i could i list the Proximal, Distal, Anterior, Posterior  . Once i dissected it i took a ventral view photo of its body.

What i learned was: Anatomy directional terms, labeling, and dissecting. I learned about some parts in a crickets body even though i couldn't find any because they looked the same. But i learned how to cut an animals body. How to use the scissor and the other thing.



TWIS #9

What I DID : This week in science, I dissected  a frogs and a mouse . My group did the frog. We prepared for the dissection by examine the body of the frog and mouse days before. We looked at the external view, internel view,  dorsal view, ventral view. We took pictures of the frogs and mice for each view. When we dissected we identify each of the internal body parts. And labeled the parts on a picture we use for are google collection.
 What I LEARNED : I learned the different parts of a frogs body. I learned how to label my pictures. And I learned a lot about the internal anatomy of the frog. I did a lot of research and found out about its body.

The organisms we dissected were a mouse and frog. The frog and mouse both have a heart, liver, and intestines. They both serve the same purpose but are positions on the body. The heart of the mouse is in like the middle of its body but in the frog its higher up almost attached to the head. The large intestine of the mouse is over more to the side and not really around the small insetine like the frog. And liver looks different in the animals but are in the same place.

What I DID : This month in science we did many things to do with zoology. We made slide shows of a biome of are choice . We included information on climate , landforms , vegatation , location and other things about a arctic tundra. We learned about are own animals food chain. And used information to adapt are animals to change into a tropical rainforest.
What I LEARNED : I learned a lot about arctic tundras.

Classification Challenge



Kingdom - Animalia (means it’s an animal)
Phylum - Chordata (means it has a backbone)
Class - Mammalia (means nurses its young)
Order - Reptilia (sounds like reptile! )
Family - Chelonioidea 
Genus - Testudines ( Most scientists recognize seven species and one subspecies of sea turtles)







My Animal is similar to the ones in my group because they all are in the animalia kingdom. And they also all have the mammalia class. That is all that is similar about are animals.


Facts about sea turtles:
Sea turtles are large, air-breathing reptiles that inhabit tropical and subtropical seas throughout the world.Only females come ashore to nest; males rarely return to land after crawling into the sea as hatchlings. Most females return to nest on the beach where they were born (natal beach). Nesting seasons occur at different times around the world. In the U.S., nesting occurs from April through October. Most females nest at least twice during each mating season; some may nest up to ten times in a season. A female will not nest in consecutive years, typically skipping one or two years before returning.They grow slowly and take between 15 and 50 years to reach reproductive maturity, depending on the species.It is theorized that they spend their earliest, most vulnerable years floating around the sea in giant beds of sargasso weeds, where they do little more than eat and grow.sea turtles eat seagrass and algae. They are mainly carnivorous as babies they will eat fish and adapt a more herbivorous diet as they age

Cricket behavior investigation

Question: Do crickets prefer fruits or vegetables ?

Hypothesis: I think that crickets will prefer fruits because David put apples into the cricket tanks

Background:  Crickets are omnivorous scavengers who feed on organic materials, as well as decaying plant material, fungi, and some seedling plants. Crickets eat their own dead when there are no other sources of food available, and exhibit predatorial behavior upon weakened, crippled crickets.
Crickets have relatively powerful jaws, and several species have been known to bite humans.
Crickets mate in late summer and lay their eggs in autumn. The eggs hatch in the spring and have been estimated to number as high as 200 per fertile female. Species Acheta domestica however lays eggs almost continually, with the females capable of laying at least twice a month. Female crickets have a long needle-like egg-laying organ called an ovipositor.
Crickets are popular as a live food source for carnivorous pets like frogs, lizards, tortoises, salamanders, and spiders. Feeding crickets with nutritious food in order to pass the nutrition onto animals that eat them is known as gut loading. In addition to this, the crickets are often dusted with a mineral supplement powder to ensure complete nutrition to the pet.

                                                         Experimental setup:
Data Table:

What I DID: What I did was record the data of crickets actions every 30 seconds. He just did everything pretty much everything over and over again. So i wrote out in words what he did and I also  drew an Illustration of how he was in the cage.

What I LEARNED: I learned how to record animal behavior data using pictures. I also learned that the cricket prefer the fruits because he ate apples twice for 2 minutes and never once ate the vegetable. And I also learned that the cricket would walk away before getting more food.

TWIS #6

What I DID : This week in science we did a thing with crickets . And we also work on classification with the dichotomous key. We did a mission challenge with jelly beans we had to Create two types of dichotomous keys in order to classify your Jelly Bellys. And we had to classify them.

What I LEARNED : I learned about different jelly flavors . I also learned In classifying both living and nonliving things, scientists have tried to provide an order to life so that we can better understand the world in which we live. All living organisms are organized (classified) according to genetic relationships. Currently the classification system contains eight levels: Domain, Kingdom, Phylum, Class, Order, Family, Genus, and Species.

Shared patterns and physical characteristics among related organisms can be organized and denoted in a classification tool called a dichotomous key. The key is used to identify organisms.  The way we use the key is by answering yes or no questions about characteristics of an organism.
