  1. Physical Science February 25th 2011 Do Now Identify the following as either Chemical or Physical properties: The density of sulfur is 2.97 g/cm The melting point of ice is 100 degrees C Hydrogen burns in air It combines with oxygen to form water It is a yellow, powdery solid It reacts with hydrogen to form a gas SWBAT identify the difference between chemical and physical properties

  2. Chapter 2 Section 2 HW Review • Classify as chemical or physical properties: • Shiny/Silvery Physical Property • Melts easily Physical Property • Density of 2.3 g/cm Physical Property • Tarnishes in moist air Chemical Property • Identify which is NOT a chemical property: • Reacts with water • Boils at 100 degrees • Is red • Does not react with oxygen • Describe uses for plastic, why is it a good choice? • Plastic can be used for almost anything! It is a good choice because it’s properties allow it to be molded into different things easily.

  3. 3) Describe characteristic properties, list some: • A characteristic property includes both chemical and physical properties. Reactivity, flammability, color, shape, texture etc. are all characteristic properties. 4) Calculate density of a rock • Density = Mass / Volume • Density = 454 g / 100 cm • Density = 4.54 g/cm 5) Calculate density of a substance • Density = Mass / Volume • Density = 0.36 g / 2500 cm • Density = 0.000144 g/cm

  4. Choice Board • Density Problems Worksheet • Completion of the density worksheet, showing all work • Supplies: Density worksheet, pen or pencil • Poster-Making • Create a poster comparing Physical & Chemical properties • Supplies: Construction Paper, Glue, Scissors, Colored Pencils • States of MatterBrochure • Create a themed brochure that explains the various states of matter using facts from the textbook: solid, liquid, gas and plasma. • Supplies: Plain white paper, colored pencils

  5. Density Problems Worksheet • For this worksheet you will calculate the density and determine what the substance is by comparing it to a chart. • Must complete both sides by the end of class!

  6. Poster-Making • You will be given index cards and selected words, you must compare the chemical properties to the physical properties and draw an example of the property on an index card. • For example: if the word is reactivity, you might draw something reacting, or bubbling

  7. Brochure • In the brochure you want to fold the paper into 3 pages to describe the solid, liquid, gaseous and plasma state. • What the states are • What the particles look like • What the movement of particles is like • Drawing of the particles and examples

  8.
