the marshmallow on top the first time 

   This week in science we did the marshmallow again. This time it was different because we couldn't talk but we could write things down. It made it hard to do things because we didn't communicate very well. I would have to admit that we did seek in some talking when david wasn't looking but still not talking when working in a group is harder than it seems. When you want someone to hold to do something it makes it hard to tell them unless you know sign  language, then you good.

second time

       Some things that i learned that was it was hard to do about this challenge was without talking. It was easier at the same time because we and done this project twice before this. The way that we did the challenge was better each time because we knew what to do already and we had more materials this time. Some things got better over time like the communication that happened. I think that i got a little better at working in group like this because you learn how to communicate with new people.

this week in science #12

You can see some fruit flies on the cantaloupe

  This week in science we did some things like making a little booklet. We made the little book so that we could keep track of what the spider does and what change we see. Some changes we could see is the spider making a web or even making a bigger web than it already did. Since our spider didn't want to make a web we had to add two more spider. After we added the two extra spiders, we notices that they all had made a web and that they caught some of the fruit flies. We added fruit flies so that the spider would have something to catch. The fruit flies that we put in the tank are genetically engineered fruit flies that cant fly, that way they cant get out of the tank.
     This week in science some things that i learned was you could alter a fruit flies so that it couldn't fly. I think that it is really cool that but also kind of sad that the fruit flies have wings but cant use them because of the alteration. Something else that i learned was if a spider is in a dark place it was

 this is one of the pictures that was taken

This week in science we did a lot of different things like we went to the park. We collected dirt, worms, leaves and other things that we thought our spider would need in order to live in the tank that David gave us. We needed to gather things that will help the spider when seal the tank close. Before we went to the park we designed what we wanted our tank to look like. Then we talked as a group to find out what we needed to get from the park.

   I learned a lot of new things like people don't like you to dig up the dirt. I guess people don't like other people digging up the dirt. Also I think it's the fact that we were teens digging up the dirt but we were doing to put the dirt back. I learned that there are a lot of different bugs in the ground when you dig really far down.

This Week In Science #10

   This month in science we meet some people from the Human Impact Institute that helped us find some problems in the world that we could base our slogan on. They helped us write the right slogan that will be easy for people to get. They also helped us make a t-shirt design that we could make into a silk screen shirt. We also tested water from three different places. We did a hardness test to see how much minerals the water had. We also make a serve that we had to answer ever night for a week. At the end, we went outside and asked people around the area asking people to answer our serve to see the what the data was. Making the serve was hard because we had to come up with questions that we could ask people that wouldn't make it weird.
      This month we learned how to make the right a slogan that would catch peoples attention not one that we be difficult from people to get. It was harder to make a good slogan that wouldn't be lame but was fun. Also i learned that it wasn't as bad as i thought when we went outside to ask people(even though most of them said no). When we went outside i asked a lady to answer the serve and she said she didn't speak English even though she was reading an English book and that just got me mad because its not like we were asking her to do a mission that was going to kill her. It was just answering questions. I thought it was a really nice experience to have because i never know when I'm going to get another chance to do this.

this week in science #9

The week in science we dissected four different animals and they were the frog, mouse, skate and the perch. My group did the perch and the skate. Kaysha and I did the skate and Timothy and NayQuan did the skate. The perch just look like a normal fish and the skate look like a sting ray but different. The dissection was really nasty because the smell was nasty. The liquid they have to put inside to keep the fish good smelled like i don't know what. It was some what a two day project. The first day we had to to take pictures of the out side and the draw the outside. The second day is the day that we dissected. Most people didn't like it but a few did.

   What i learned this week was that the perch was very similar to a fish. The organs were very small. It had gills instead of lungs. I think the hardest part about doing the perch was finding out what gender it was but at the end i found out it was a male both times. The boys had the skate and it was really big and flat.it had spikes on the back of it and they had a male one day and a female the next. The skate was the easyest to find the gernder.What our had to dissect was the skate and he perch. They were both very nasty and the biggest one was the skate. It was three times as big as the perch and it had a lot more water in it than the perch. Three similar things it had in common was the that the skin. They both had skin but it was very different the skate the top of the skate skin was ruff but the bottom was very soft

this Week In Science #8

this is the side view of the craw fish

this is the ventral view of the craw fish

 This week in science we learned a lot new vocabulary and what they mean like dorsal view which mean the back/spine of something or something. Ventral view which is the belly or abdominal view of something. The features of the craw fish is that it has a lot of leg. There  are 4 main legs and then on the tail there are 4 smaller legs. The environment of the craw fish is the water. The posterior of the craw fish is the head and the anterior of the end of the tail. The adaptation is that it looks like a smaller lobster. Maybe is once was a lobster but over time became smaller due to the water level.

   
This week in science we dissected a craw fish and a cricket. It was really fun and it was a fun experience to have. When i did this in 8th grade is was different because we had to do a frog. The smell was the same and it was not a good smell. I really liked dissecting but i can't take the smell, which makes the dissection non fun. I was hard to cut open the craw fish because it was tiny and when you were cutting open the chest all you heard was the crunches. i think that was the hardest thing to do. All the intestines were really small and it was hard to tell where the brain was

this week in science #7

  This week in science we learned i learned how to screen case and showed my team mates how to do it to. I also a bunch of new things about the ocean like there is different layers to the ocean. the project was called Zoology and every group has a different thing to do.
     What we did was make a video with our voices called screen case and i think that was the hardest thin to do because one little mistake you can hear it. Sadly there is no way to get that mistake out because you cant edited it .

circkets behavior invesitgation

Question:Do crickets prefer wet or dry environment?

this shows the movement of the cricket

Background Research:Crickets like to eat rotten tomatoes, other insects, each other and moist things to get moisture in there body. Crickets also eat smaller beetles, grass and crops. If your breeding them you should feed the crickets strawberries, cucumber, fruit loops and damp sponges.                                      

this is the cricket on the dry side of the tank

Hypothesis: If crickets go more to the wet side of the cage then that means that the crickets prefer wet land over dry because they need the moisture in their body.

What i did to do this investigation is i made connecting lines that show the cricket's movement during a period of time

This week in science #6

    This week in science week we did a lot of different stuff. One of the things that we did was doing some background research on crickets to see what kind of things they eat. Also we were deciding on a project to do to find out what kind of surface or what kind of light they like. For example do they prefer light or dark,hot or cold,smooth or rough surfaces etc. Finally we were making a dichotomous key about jelly beans.

 this is an example of a dichotomous key

   What i learned this week was the different things the crickets like to eat. They like to eat rotten tomato,other insects,each other and moist things things to get moisture in their body. Also i learned what a dichotomous key is. It is a chart the puts thing in its own category but what it is.

this week in science #4

  This week in science we started and finish our second plant investigation on the plant Brassica rapa. Everybody had to pick a job for the old list and plus the new ones that made this investigation much better than it was before. We had to started the project on Tuesday and on Wednesday we had to finish it up. This project was probably a little harder because we had to do a background research on the plant. I thought that it was hard to fine a website that had a lot of information that that can help.

  Last week in science we did a second chart that was more detailed than the first one and this time we had the data already. We had to use the numbers to make a line graph. The graph in my group shower the growth in three different plants that was planted in different things. Like soil,sand and fertilizer .
