Rube Goldberg #1

In class, we were introduced to a project called “The Rube Goldberg Project”. Rube Goldberg is known for his contraptions and his over complicated machines. The rules of this assignment, were to have more than 8 steps, and not be able to use any human power or any living source. We had top choose partners and I chose Arun. Me and Arun had trouble with the design, we tried coming up with possible ideas we could use our contraption but we decided to not use them. The resources we used were a plastic ball, a pipe, some dominos, CD cases, a candlestick, plushy Pikachu, string, a book, fruit loops, and a bowl.

 

Ecosystem Blog Post – Tundras

The tundra is a snowy, dry place that is found far north like Russia, Alaska, Canada, and Scandinavia. There are three types of tundras: Arctic, Antarctic, and Alpine. The tundra is a cold place during winter and summer and it’s a barren place. It’s earth’s youngest biome and it formed over 10,000 years ago.

Consumers are animals that eat other animals. In the tundra, the consumers are the snowy owl, arctic fox, and polar bears. The arctic fox blends in with the snow so the prey does not see them. The snowy owl hunts lemmings and mice. The polar bear hunts seals, fish, and penguins.

Producers are plants that produce their own food. Trees produce oxygen and trees are producers. Although they produce their own food they do absorb water and sunlight. The producers are grass, moss, and lichen.

The tundra is a unique place because it is a barren, cold place and it’s earth’s youngest ecosystem. It held mammoths several thousand years ago. Mammoth are extinct now, but they still find mammoth skeletons today. Megafauna are animals that are huge. Megafauna means mega = huge; fauna = animal.

The tundra is really awesome and I recommend researching it more. I hope that you liked this blog post and I hope that you will research more.

 

Week two plant unit reflection

Our soapy water plant is not growing so my group and I think the they did not get enough water or it was just a died at the beginning. On May 18th our plants started to bloom flowers. There were 8 buds on cell 2 and 3 buds on cell 4. We think the chemicals in the soapy water killed it.
