Burning in Pure Oxygen: First we combined manganese dioxide MnO2 and hydrogen peroxide H2O2 solution to produce oxygen O2. Then we lit a splint on fire and blew it out creating a smoldering splint. We took that smoldering splint and put in in the beaker with the pure oxygen to see what would happen. When we placed the splint in the beaker we surrounded the splint with a much higher concentration of oxygen molecules than can be found in air. This, along with the increase in temperature, dramatically sped up the reaction rate, so the splint ignited with a bright flame.
Blue bottle: First we made a solution containing a reductant (glucose) and methylene blue. Then we added some NaOH to make the solution basic. The oxygen dissolved in the water accepts the electrons but doesn’t interact with glucose. Adding the methylene blue helped by acting as a carrier taking electrons from glucose and passing them to oxygen.
It is hard to believe that the year has come to an end and some of you will be moving up to the elementary program, going to new schools or returning next year. I want to let everyone know it was a great year, and that I enjoyed every moment of teaching all of you. We made a lot of great memories with a lot of jokes and silliness. I hope you feel the same and that you will take what you have learned this year and build on it as you continue your education. If you are not returning next year, please come back to visit all your teachers, because we will truly miss you!
Dinosaurs: We learned that dinosaurs roamed Earth for about 165 million years and that there were hundreds of species. Then about 65 million years ago a huge meteorite or comet hit the Earth, making dinosaurs become extinct. Some dinosaurs we studied were diplodocus, tyrannosaurus, stegosaurus, brachiosaurus and triceratops.
Magnetizing magnesium: We made a solution with magnesium and iron (ferrous sulfate FeSO4). When we placed a magnet underneath the particles became magnetic because the Fe2+ from the FeSO4 solution turns into metallic iron Fe on the surface of the magnesium particles, while the Mg turns into Mg2+ and ventures out into the solution.We basically ended up with magnesium shavings covered with a thin layer of iron which will stick to a magnet.
Metal contest: First we prepared a copper sulfate CuSO4 solution and a tin chloride SnCl2 solution. Then we put pieces of zinc into both vials. When we put a piece of zinc wire into the solution of copper sulfate we watched a deposit of metallic copper form on the piece of zinc. The zinc forced copper out of its salt composition. The same happened in the vial with the zinc wire and the tin chloride solution. However, we noticed that the vial with the tin wire in the copper sulfate solution reacted slower than the tin chloride solution.
Pronoun: The kindergarten students learned that a pronoun is a word that takes the place of a particular person or thing. For example the word “dog” is a noun and the words “it” “she” and “he” are pronouns that can replace the noun “dog”.
Cursive Handwriting: The students practiced writing the lowercase cursive words: cot, bag, stop, frog, bell, will.
Australia is the smallest of the seven continents. It is just one country surrounded by water. Australia is called the land “down under” because it is located under the equator. It has two big cities Sydney and Melbourne. The central part of Australia is called the “outback.” Australia produces more wool than any other country.
Asia is the biggest of the seven continents. It has more people living on it than all of the other continents combined. Asia has many different kinds of land such as: tundra, evergreen forest, wide grasslands, sandy deserts and tropical rain forest. The highest and lowest places on Earth are found in Asia which are Mount Everest and the Dead Sea.
Antarctica is an icy continent with no countries or people. Most people who do visit are scientist or visitors who are observing all the amazing animals and the climate. Antarctica has tall mountains that are covered by snow and ice. It also has thick sheets of ice and giant ice chunks known as icebergs.
North America: Is the third largest continent in the world. There are four big countries: Canada, Greenland, the United States and Mexico. It has high mountains and flat grasslands. It has swamps, forest, deserts and even volcanoes. Most people speak English, Spanish or French.
South America: Is the fourth largest continent in the world. It has tall mountains and flat grasslands. The worlds largest rain forest is in South American and is called the Amazon rain forest. There are may unusual plants and animals.

Vowels and consonants: The students learned to recognize and distinguish vowels from consonants, which is an important step in the development of reading and writing skills. We talked about how all words contain at least one vowel. The students were quickly able to recognize the vowels, which is great because they will have a strong foundation for learning rules and spelling patterns for short and long vowels, final vowels, unaccented vowels, silent vowels and irregular spellings.
Cursive Handwriting: The students practiced writing the lowercase cursive words: last, frisk, grab, kid, hat and quest.
