Musical Instruments and Sound- Weekly Blog (3/11-3/15)

Sound Energy - Musical Instruments by SolPass Summary We understand how sound is produced, and how sound waves can travel through different mediums, but how do musical instruments produce sound? There are hundreds of instruments in the world, producing various pitches, tones, and chords. There are three main types of instruments: wind, percussion, and string. The sound is produced differently based on the type of instrument. The first type of instrument is a string instrument. In a string instrument, the sound is created from the vibration of strings. For example, when you play guitar, you pull on the strings. As the strings vibrate, the air molecules start vibrating as well, producing sound. The next type of instruments are wind and brass instruments and are made when we blow sound into them. The shape and position of the instrument affect the overall tone and pitch. The most common kind of wind instrument is a reed instrument. Blowing on the reed causes it to vib...

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...

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 ...
