  1. CPW Learning Intentions - Today, I am going to address these College Readiness Standards in Science: Interpretation of Data 13-15 Interpretation of Data 24-27 Scientific Investigation 24-27 Scientific Investigation 20-23 Scientific Investigation 24-27 Interpretation of Data 16-19 Evaluation of Models, Inferences, and Experimental Results 20-23 SQUADS #4 “9th Grade Science” Success Criteria – I know I am successful when I can select data from a simple graph, understand the methods used in a simple experiment, determine the experimental conditions that would produce specified results, and find basic information in a brief body of text.

  2. Quick Note! • Today’s questions are based on the printed passage you will receive shortly. After reading your passage individually or as a group, choose the best answer to each question. You may refer to the passages as often as necessary. • You have 2 Minutes to read your passage!

  3. 9th Grade Science #1.A solution of sugar in water is NOT supersaturated when 300 g of sugar and 100 g of water are mixed at a temperature of: • 20 degrees Celsius. • 40 degrees Celsius. • 50 degrees Celsius. • 70 degrees Celsius.

  4. 9th Grade Science #2. In order for 250 g of sugar to completely dissolve in 100 g of water, the temperature of the solution would have to be at a minimum of: • 15 degrees Celsius. • 25 degrees Celsius. • 45 degrees Celsius. • 65 degrees Celsius.

  5. 9th Grade Science #3. At 100 degrees Celsius, the solubility of sugar in water would most likely be: • less than 250 g of sugar in 100 g of water. • between 250 g of sugar and 350 g of sugar in 100 g of water. • between 350 g of sugar and 400 g of sugar in 100 g of water. • more than 400 g of sugar in 100 g of water.

  6. 9th Grade Science #4. In order to produce rock candy at 20 degrees Celsius from a solution of 300 g of sugar not completely dissolved in 100 g of water, the solution must be: • first heated above 60 degrees Celsius, then slowly cooled to 20 degrees Celsius. • slowly stirred at 20 degrees Celsius. • slowly cooled to 0 degrees Celsius. J. slowly cooled below 0 degrees Celsius, then heated to 20 degrees Celsius and stirred.

  7. 9th Grade Science #5. How much sugar must be added to a solution of 50 g of sugar in 100 g of water at 45 degrees Celsius in order for the solution to be supersaturated? • more than 10 grams • more than 20 grams • more than 100 grams • more than 200 grams

  8. 9th Grade Science #6. Solubility is defined as: • a supersaturated mixture. • a mixture that is made by dissolving a solute in a solution. • the amount of solute that can be dissolved in a solvent at a given temperature. J. the temperature that causes supersaturation.

  9. 9th Grade Science #7. What is the approximate difference in temperature for the solubility of 200 grams of sugar/100 grams of water and 250 grams of sugar/100 grams of water? • 10 degrees Celsius • 20 degrees Celsius • 30 degrees Celsius • 40 degrees Celsius
