Colligative Properties—
Student Laboratory Kit
By: The Flinn Staff
How are nutrients transported through the roots of plants? Why do cucumbers shrivel up to pickles when placed in a salt solution? Why does adding antifreeze to water keep it from freezing at 0 °C? This unique kit provides a complete experiment for all three colligative properties of solution—freezing-point depression, boiling-point eleva- tion, and osmotic pressure. In this three-part experiment, students first measure boiling points to determine how the concentration of a solu- tion changes due to osmosis. Students then observe the freezing point changes of water when different chemicals are added. Finally, students use a microscale procedure to investigate the effect of sodium chloride concentration on the boiling point of the solution. Includes reproduc- ible student handouts, detailed background information, Notes with sample data and answers to questions, and all chemicals and consum- able supplies needed to perform the lab.
Complete for 30 students working in pairs.
Chemical Mixtures and Solubility: Make Your Own Lava Lamp— Student Laboratory Kit
By: The Flinn Staff
Experience the hypnotizing lava lamp, with its modified colored bubbles sinking and rising. Your students will make their own version of a lava lamp and enjoy its colorful bubbles floating around! When students measure equal parts of water and oil, they will make conclu- sions about density and polarity. What better way for students to learn about chemistry than to experience something that captivates them?
Complete for 30 students working in pairs.
Qualitative Analysis of Sulfite
Ions in White Wine—Guided-Inquiry Kit
By: The Flinn Staff
This new, innovative guided-inquiry lab can be used as part of your AP chemistry curriculum, as one of the six guided-inquiry investigations required by the College Board. This lab covers precipitation reactions, qualitative analysis, acid-base reactions, chemical equilibrium and Le Chatelier's principle by asking students to determine the amount of sulfite ions in white wine. Your students will love exploring these complex chemistry topics in a unique, fun way that they can relate to the everyday world.
Complete for 24 students working in groups of 4.
