Converting to Inquiry Science Labs The Plan Modify current procedure-based experiments Modify current procedure-based experiments Teach materials and techniques so students can design their own experiments Teach materials and techniques so students can design their own experiments Assess learning with presentations that emphasize peer communication Assess learning with presentations that emphasize peer communication

Converting to Inquiry Science Labs Example: volumes lab Before – We will approximate the volume of a person using cylinders, rectangular solids, cubes, and spheres. Use centimeters (cm) for all measurements.

Converting to Inquiry Science Labs Example: volumes lab Before –

Converting to Inquiry Science Labs After – An alien race has run out of food and is planning to import humans. For proper nutritional labeling, they need to find out the volume of each food item. They promise to spare you if you will measure the volume of your lab partner. What is the approximate volume of your lab partner measured in cubic centimeters? Example: volumes lab

Converting to Inquiry Science Labs After – Example: volumes lab

Converting to Inquiry Science Labs Before – calculate the volume of one mole of a gas at STP Example: molar volume

Converting to Inquiry Science Labs Example: molar volume Dear chemistry students, Our company is willing to donate 1 mole of hydrogen gas to your instructor for demonstrations. Unfortunately, we don't know how to measure out a mole of this gas because we don't have a scale and we don't know the volume of 1 mole of gas. After producing the hydrogen gas by reacting an active metal with an acid, what volume at what pressure should we collect to have 1 mole at lab temperature (20 degrees Celsius)? Also, what is the volume of 1 mole at STP? To figure this out, you should weigh a piece of magnesium and measure the amount of gas it produces during the reaction. After –
