This Week In Science #15

This week in science it was our third time doing the marshmallow challenge. With the same groups as the last two times we were in, we tried to build the tallest free standing tower. This week doing the challenge we built two towers. This week both of our towers weren't taller than our last tower. This week in some weird way even though our tower wasn't taller than our others i felt like we worked together better because we weren't able to talk.
This week in science working in the same old group for the third time wasn't any different. I think I learned that its being in a group with the same people for the whole year can be a good thing because we have already learned and know so much about each other. But it would have been good to experience these challenges with different people to see how others work. I also learned that in cases like the marshmallow challenge its good to have others working with you because you have extra sets of hands helping you. I think if I would have done this challenge by myself It would have been a complete failure!

TWIS #14

This week in science we worked in groups and talked about about hippo. Hippo stands for a group of scientific words, when people are talking about hippo they aren't actually talking about a hippo.
H- Habitat loss, when people cut down trees their destroying animals homes.
I- Introducing species, new species are introduced.
P- Pollution, gases and people are destroying animals habitats because we're filthy and we liter.
P- Population growth, when theres too many of one species living
O- Over consumption, Humans are using too many products, we'r over using things that we should control what we use.

This week in science i learned what hippo meant. What each letter stands for and its meaning. I learned about different oils and gases. I learned how to work in a group of 4 better, its hard when everyone has different ideas and opinions but its better to have ways of learning how to get along better. I learned that a lot of animals are endangered, and are losing their habitats because of what we're doing to their homes.

This week in science #13

If I were to remove all of the plants in the tank and seal it up the spider would eventually die, because plants go through the process of photosynthesis to produce sugar and oxygen. Spiders need oxygen to breathe and if there are no plants in the tank there would be no oxygen which would kill the spider.

This week in science 11

     This Week in science we went out into the park to collect stuff to put into our spiders ecosystem. We made annotated documents, answering questions and summarizing what we collected and did when we went to the parks. We collected twigs, and leaves, pebbles, a rock and dirt. We put branches in our tank too. We accessed our prior knowledge, writing the definitions of what we thought on certain words.
     I learned from reading on the internet spiders don't eat earth worms. So putting the worms into our tank was kind of pointless since the spider wont eat them. Worms do keep dirt moist so thats a plus. Spiders only eat specific types of worms and crickets etc. I learned new words and their meanings when we did the definition activity with post-its. I also retaught definitions of words i learned last year because I had forgotten them.http://www.123rf.com/photo_8972415_tarantula-spider-poecilotheria-metallica-in-front-of-white-background.html <--- My spider picture :)

This Month In Science #10

This picture was 1 of our ideas drawn out on paper, we ended up picking this idea for our final add. We are going to connect the two gears in our final add.

This week in science David was absent all week. We did some projects and activities with Jamie. We tested 3 different bottles of water to see which one was the cleanest. My group also worked some more on our transportation projects. The transportation and energy groups teamed up and did some experiments to see which objects used the most electricity. We also created surveys and went out to the streets to ask people to answer them for us. A few people from the human impacts institute came to visit us and help us create ideas for what we were going to put on our posters and t-shirts. We started our project, human impact add campaigns. We had to create adds, posters about our group, which was transportation. We had multiple ideas drafted but we decided to go with a particular idea because it would be the easiest to put on a t-shirt. We now are going to put our drawings on t-shirts.

This week I learned many different things. Like for one thing blow dryers use a lot of power when plugged in and on. I also learned that our school water was the dirtiest water from all three different types of water Jamie brought to school. I also learned that even when objects aren't in use or on, or plugged in they still use power. I also learned that people who work for the trains, i think their called commissioners are doing more work than ever before. Their trying to make the city a more comfortable and safe place. Where there could be less traffic and more places for people to hang out at. I learned that making an add campaign is really hard especially if your working in a group, because so many people have different ideas and different opinions on what we should and and how we should do it. So coming up with a final add was hard and a long process.
