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 ...

Types of Rocks (2/26-3/2)

https://i.ytimg.com/vi/qFEBPD3JEOM/maxresdefault.jpg Summary The three main types of rocks are igneous, sedimentary, and metamorphic. These rocks are different and classified by how they look and how they are formed. The first type of rock is a sedimentary rock. Sedimentary rocks are formed from particles of sand, pebbles, shells and other small bits of material, called sediments. The sediments gradually create layers and eventually harden into rock.  Sedimentary rocks are pretty soft and may break apart easily. There are sediments visible in the rock, and this is the only rock that contains fossils. Some examples of sedimentary rocks are conglomerate and limestone. Igneous rocks are formed when magma cools and hardens inside of the Earth. The magma cools either inside of the Earth or erupts from volcanoes in the form of lava. The magma cools very quickly and  no crystals will form. This leaves the rock looking shiny and glass-like. Occasionally, when ign...

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...
