Includes Easy-to-Use Chromatography Paper Strips and Vials |
Two Sizes Accommodate Large or Small Classes with Your Choice of Lab Activity Packages
Available in your choice of sizes: enough materials for a class of 32 students working in eight lab groups, or enough materials for a class of eight students working in two lab groups. Refill kits for the larger size are also available, so you can perform the labs many times over and save money.
We listened to you! Coupons redeemable for the perishable materials are now included in our lab activities, giving you more flexibility!
With a thorough overview of photosynthesis, chromatography, and spectrophotometry, this comprehensive lab activity helps students perform all the required investigations on plant pigments and photosynthesis. In the process, students learn the principles of chromatography, calculate Rƒ values, and carry out experiments that show how light intensity, light wavelength, and temperature affect the rate of photosynthesis. After learning the proper procedure for extracting chloroplasts from spinach leaves, students separate plant pigments with paper chromatography and study the pigments’ relation to photosynthesis. In addition, they measure the rate of photosynthesis in isolated chloroplasts using a unique method that involves the reduction of the dye DPIP (2,6-dichloroindophenol). The change in color from blue to clear, effected by the transfer of electrons, is measured with a spectrophotometer, available separately.
