Making a Calibration Curve for Starch Concentration

Scientists need to have mastered algebraic slope-intercept concepts in order for this instructional activity to be effective. They will measure and graph solar panel output as a function of the amount of radiation striking it,...

You are what you eat, as they say! Are you more starch or more protein? Young scholars use their knowledge of each component to test different foods for their content. Using multiple indicators, individuals describe the protein and...

Which sports drink provides the best pick-me-up after the big game or grueling workout? It may not be the one you'd think! Food science is the focus in a surprising lab activity. Pupils use colorimetry to determine the amount of protein,...

What could be so difficult about preparing a solution? Show science scholars the proper way to prepare standard solutions using a video from JFR Science. The narrator discusses solution preparation using a solid solute as well as...

Challenging and interactive—everything you need in a resource! Chemistry scholars manipulate a series of puzzles focused on molarity. The teacher's guide provides support for implementing the lesson, as well as printable materials.

It's pretty common to determine the dissociation constant for an acid or a base ... but, what about a protein? Challenge your class with a virtual lab designed to further develop their acid-base chemistry skills. Individuals determine...

Students can use a Colorimeter to determine the relationship between concentration and absorbance of nickel sulfate solution (Beer's law). They will then determine the concentration of a unknown sample using the standard curve.

Students investigate the property dependence between concentrations and boiling point. First, they investigate the boiling point of various liquid solutions. Then they analyze data collected from the entire class to generate two boiling...

Heat up your lessons on boiling points. The resource provides a three-part activity: first, groups find the boiling point of solutions; second, they create boiling point curves for salt and sugar solutions; and third, they mix a solution...

Sugar isn't good for you, but it's great for microbes. A simple experiment has pupils investigate the digestion of starch by microbes to produce sugars. They apply two bacterial cultures, an amylase solution, and distilled water on a...
