Structure of the Periodic Table - 9/25-9/29

https://image.slidesharecdn.com/theperiodictable-110223090122-phpapp01/95/the-periodic-table-7-728.jpg?cb=1298451775 Summary: This week, we have been learning about how the periodic table is arranged and the different patterns that are in the rows  and columns. In the periodic table, the rows are called periods. Along the rows, the elements are organized by atomic number (the number of protons.) The rows also have the same energy level or the number of electrons. For example, in the first row, all of the elements' atoms have one energy level, and so on.The atomic mass is the number of neutrons plus the number of protons. The atomic mass can be a decimal, and it is ordered increasingly. The columns in the periodic table are called groups or families. Each family has a name. For example, group one is composed of alkali metals which is the family with Lithium, Sodium, and more. Each group also has the same number of outer, or valence electrons. The elements in group one ...

Food Chains and Food Webs (10/2-10/6)

Above is a food web http://maggiesscienceconnection.weebly.com/habitats-food-chains--webs-trophic-pyramid.html Summary: This week in science we were learning about food chains and food webs. Food webs are a lot of food chains that are linked together. For example: In a food web there are a lot of different plants and animals, and it shows where they get energy from. Food webs are much more complex than food chains as you can see in the picture above.  Food chains are chains that connect the different things that eat each other. In a food chain, plants are the only living organisms that make their own food. Check out my blog about  photosynthesis . There is a producer (a plant because it makes its own food) Primary consumers (animals that eat plants), secondary consumers (animals that eat other animals that depend on plants). There is also decomposers (fungi & bacteria decompose the dead body making nutrients which the plant uses during photosynthesis to get en...

The Carbon Cycle (3/20-3/24)

https://d32ogoqmya1dw8.cloudfront.net/images/eslabs/carbon/global_carbon_cycle_1427132279_456.jpg Summary: This week, we learned about the carbon cycle. The carbon cycle is a process that carbon travels in. There are six reservoirs or places that carbon travels in. G reenhouse gasses like carbon dioxide are dangerous because they are in our atmosphere and are causing the planet to become warmer. In other words, greenhouse gasses create an extra layer (like a blanket) in the atmosphere. This is because humans have burned so much fuel that there is about 30% more carbon dioxide than there was about 150 years ago. On the other hand, without greenhouse gasses, the Earth would be a frozen world. The six reservoirs are soil, the atmosphere, surface water, deep ocean, marine life, and land plants. 5,000 megatons of carbon are released into the atmosphere as fossils fuels are burned each year. When carbon is in the atmosphere, it is added with two oxygen atoms and becomes ...
