Name __________________________ Chemistry Scavenger Hunt Atoms and Molecules Visit the Chemistry Links page at the Kid Zone to find these sites! Go to http://sciencespot.net/Pages/kidzone.html to search for answers. You can also click on the links above the questions to search for answers as well. Chem4kids Go to the “Matter” area to find the answers to these questions. 1. Matter is anything made of and . 2. It is anything that has . Go to the next page… 3. There are three main phases of matter: , , and . There is also a fourth and fifth phase,They are and , but they exist at very high temperatures. Science Is Fun Go to the “ChemTime Clock” area to find the answers to these questions. 1. All materials, whether solid, liquid or gas, are made of . Atoms are the smallest of . Scientists have found over different kinds of atoms. The many different materials we encounter are made from of these atoms. A material in which all atoms are the same kind is called an . Therefore, there are over different elements. Each element has been assigned a number, called its . 2. Search for information about each element on the Chem Time Clock. Use the chemical symbol to identify each element. Lightest atom Lightest metal Found in borax Atomic number of 7 Major component of air Used in making toothpaste An element in table salt Atomic number of 12 Used in “mag” wheels Atomic number of 9 Used in laundry detergents First discovered in the sun Beryl, emeralds, and aquamarine Atomic number of 11 Diamond and graphite 2nd most abundant element on Earth Atomic number of 3 Glows red-orange with electricity Name from Greek word for sun Most common atom in universe Found in buckyballs Atomic number of 2 Chem4Kids Go to the “Atoms” area to find the answers to these questions. 1. What do scientists call the areas where electrons are most likely to be found? 2. What are the three “pieces” to an atom? Quia! Chem Games Choose the “Common Chemicals” game. Play the game to discover the names of these common chemicals: Acetic acid = Sodium bicarbonate = Ascorbic acid = Sucrose = Retinol= Sodium chloride = Acetylsalicylic acid = Sodium hydroxide = Thiamine = Cobalamin = EXTRA CREDIT: Go to the “Biochemistry” area to find information needed to help you answer these questions. 1. How many chlorine atoms would be in a compound with the name: a. dichloride? b. tetrachloride? c. decachloride? 2. What do you get when you add the following atoms together? a. one carbon and one oxygen? b. one carbon and two oxygen? c. one carbon and four chlorine? Once you are finished, you may choose any site from the Kid Zone to explore! SUBMIT YOUR PAPER IN TO YOUR TEACHER BY THE END OF CLASS! T. Trimpe 2001 - http://sciencespot.net/
