Fizz is the F in FACTSS which is an acronym for evidence of a chemical reaction. When bubbles are caused, it is creating a new substance and when a new substance is created, a chemical reaction is happening.]]> 2019-02-21 18:15:41 UTC https://padlet.com/hannahkong2023/8i6z4asuk0ku/wish/333780189 hannahkong2023 https://padlet.com/hannahkong2023/8i6z4asuk0ku/wish/333940846 The Statue of Liberty used to be a copper color but because of all the water around it and oxide, it turned from copper to green. Therefore it is a chemical reaction because the color changed during and after the chemical reaction.]]> 2019-02-21 22:10:27 UTC https://padlet.com/hannahkong2023/8i6z4asuk0ku/wish/333940846 hannahkong2023 https://padlet.com/hannahkong2023/8i6z4asuk0ku/wish/334243118 Baking cookies is a chemical reaction because before put the cookies inside the oven there is no smell but after you take the cookies out of the oven they smell delicious. This indicates a new change in smell after the reaction happened.]]> 2019-02-22 17:32:35 UTC https://padlet.com/hannahkong2023/8i6z4asuk0ku/wish/334243118 hannahkong2023 https://padlet.com/hannahkong2023/8i6z4asuk0ku/wish/334246080 Burning wood is an example of a chemical reaction that results in a color change. Before you burn the chemical reaction occurs, the wood is a brown like color, and after the reaction occurs, it changes the color from brown to black.]]> 2019-02-22 17:38:28 UTC https://padlet.com/hannahkong2023/8i6z4asuk0ku/wish/334246080 hannahkong2023 https://padlet.com/hannahkong2023/8i6z4asuk0ku/wish/335117106 Cooking bacon is a chemical reaction because the reaction causes aroma, a new smell. Before the reaction, bacon doesn't really give off any smell but once you let it cook for a while, you can smell it from a mile away! And it smells delicious. Besides making a new smell, there is also a temperature change and also, the oil starts to fizz on top of the bacon during and after the chemical reaction.]]> 2019-02-25 21:44:38 UTC https://padlet.com/hannahkong2023/8i6z4asuk0ku/wish/335117106 hannahkong2023 https://padlet.com/hannahkong2023/8i6z4asuk0ku/wish/335665042 Hand warmers are chemical reactions because in order for it to become warm you start shaking it and squishing it and the molecules inside it start to heat up and after the chemical reaction, you have a warm pouch.]]> 2019-02-26 21:59:50 UTC https://padlet.com/hannahkong2023/8i6z4asuk0ku/wish/335665042 hannahkong2023 https://padlet.com/hannahkong2023/8i6z4asuk0ku/wish/335666442 Setting off fireworks is an example of a chemical change because once you light it on fire, the temperature changes. Because it is so hot, it sets off the gunpowder which leads the fireworks to be released then you can see them in the air.]]> 2019-02-26 22:04:13 UTC https://padlet.com/hannahkong2023/8i6z4asuk0ku/wish/335666442 hannahkong2023 https://padlet.com/hannahkong2023/8i6z4asuk0ku/wish/336019170 Elephant toothpaste is a type of chemical reaction because when you add the hydrogen peroxide, potassium iodide, food coloring, and dish soap together the mixture starts foaming and creates a new substance as it flows out of the bottle. Aside form it being a new substance, it is also a temperature change because after it erupts, it gets warm.]]> 2019-02-27 17:17:52 UTC https://padlet.com/hannahkong2023/8i6z4asuk0ku/wish/336019170 hannahkong2023 https://padlet.com/hannahkong2023/8i6z4asuk0ku/wish/336028899 Adding these two clear liquids together makes a solid. During the chemical reaction, you can see that a yellow solid is made in the middle of a clear mixture. The yellow sets at the top and bottom of the bottle and starts to drop down and make the whole mixture yellow. Along with making a solid, it is also a color change because it turns from two clear liquids to one yellow mixture.]]> 2019-02-27 17:30:30 UTC https://padlet.com/hannahkong2023/8i6z4asuk0ku/wish/336028899 hannahkong2023 https://padlet.com/hannahkong2023/8i6z4asuk0ku/wish/336545306 Mixing sugar and sulfuric Acid is a chemical reaction because once you pour them together and you wait a while, the mixture slowly rises up and creates a new black substance. This shows that a new substance was created and indicates a chemical reaction has occurred. Along with making a new substance it is also temperature change and a color change. After you poured them together, it turned black and when it shot out of the glass cup, it started steaming.]]> 2019-02-28 18:03:52 UTC https://padlet.com/hannahkong2023/8i6z4asuk0ku/wish/336545306 hannahkong2023 https://padlet.com/hannahkong2023/8i6z4asuk0ku/wish/336548485 When you added 3 drops of potassium chlorate onto the table then dropped one drop of silver nitrate on top of it the silver nitrate turns brown inside the yellow liquid and forms a solid while it is trapped inside it. This is a chemical reaction because a solid or precipitate was formed.]]> 2019-02-28 18:09:23 UTC https://padlet.com/hannahkong2023/8i6z4asuk0ku/wish/336548485
