1.  A scientist combined two liquids into a flask. The temperature of the flask increased, the combined substance started bubbling, and a strong odor was given off. Was this an example of a mixture or a compound and why? a.It is a mixture because the temperature of the flask increased, and there was an odor. b.It is a compound because there were two liquids combined together. c. It is a compound because a chemical reaction occurred. Bell Work 11-17-14 PLICKERS

21. Procedure:  With your lab group, go to each lab table and compare and contrast the different items in the dishes.  Categorize the materials in each dish as element, mixture, or compound and record the information in your data tables.  Discuss your lists. Investigating questions:  On your lab sheet, describe the three types of matter.  Give some examples of elements, mixtures, and compounds.  Explain the different properties of each group of materials. NOTE: Think of the washer, bolt, and nut as an individual atom! EMC Lab: Element, Mixture, Compound Hands-On Lab

22.  New materials are one of the greatest achievements of every age.  Material engineers are focused on understanding different materials so that they can create new materials with desired properties. For, example they take advantage of the varying strengths and abilities of different materials to make composites that are engineered from two or more materials with different PHYSICAL and CHEMICAL properties.
