Preparation of Esters—Laboratory Kit
By: The Flinn Staff
Ponder the taste of your favorite fruit. That unique flavor is the result of the combined senses of taste and smell. In the case of fruits, the primary flavor and fragrance ingredients are organic compounds called esters. By combining different alcohols and carboxylic acids, students synthesize four distinct esters. Students will enjoy learning about chemical formulas and equations, functional groups, organic chemistry and equilibriums with this fragrant activity!
Complete for 24 students working in pairs.
Discovering Density—Laboratory Kit
By: The Flinn Staff
What better way to understand the concept of density than by using scien- tific observations, patterns and trends to determine relationships among variables? Students determine the density of two “mystery metals” by plotting mass and volume measurements and then analyzing the preci- sion and accuracy of their data. Students feel like accomplished scientists discovering the concept of density for themselves just as Archimedes did with a crown many centuries ago.
Complete for 24 students working in pairs.
Beverage Density—Laboratory Kit
By: The Flinn Staff
Have you ever noticed it is easier to float in the ocean than in a swimming pool? This is because seawater has greater density than fresh water due to the presence of dissolved salt in the ocean. What factors determine the density of a solution? Can the density of a solution be used to determine how much of a particular substance is dissolved in it? Determine the sugar content of beverages by creating a calibration curve using the density of five reference solutions by comparing the results against provided values on nutrition labels.
Complete for 24 students working in pairs.
Atomic Spectra—Laboratory Kit
By: The Flinn Staff
When a pure atomic gas such as hydrogen or helium is subjected to a high- voltage electrical discharge, light is produced and the gas glows. When this light passes through a diffraction grating, a spectrum is produced. Instead of seeing the familiar rainbow of colors, light emitted by the gas produces a series of bright, colored lines. This series of bright lines is called an atomic emission spectrum and is unique to each element.
In this experiment, students investigate continuous and line emission spectra from various sources of light using a spectroscope. Students also use the spectroscope to observe the atomic spectra of different elements in spectrum tubes and to identify the elements that may be present in fluorescent lights, street lamps and novelty “neon” lamps.
Complete for 24 students working in pairs. Gas discharge tubes and power supplies are required and available separately.
