Color Change Chemical Reaction
Also known as the traffic light reaction, indigo carmine produces a colorful demonstration In this activity, a redox indicator (indigo carmine) changes color as a result of electron transfer. The introduction of oxygen through swirling causes the indigo carmine to turn green as it is oxidized. Upon standing, the indigo carmine is reduced by the […]
Optics of the Human Eye
Background Geometric optics explains how optical devices (such as lenses and mirrors) create images by considering that light travels in rays, which are straight lines emanating from a light source or reflected from an object. A ray diagram is a useful tool in geometric optics; it describes images formed by lenses or mirrors. A ray […]

Investigating Phenomena: What Causes Flowers to Open?
Carolina Phenomenon Phenomena-driven science! Phenomena are observable, naturally occurring events that are everywhere and spark student questions and investigations. Ask students to observe the DCI-linked phenomenon in the video and complete the attached student sheet prior to remote learning discussions. Observations: Carefully watch the video of the opening flowers, which occurs over 13 hours. Gather […]
Plant Biodiversity Field Activity
Take your class outdoors to study biodiversity. What is biodiversity?? Simply stated, biodiversity is the number and variety of organisms within a particular geographic area. In this activity, students go outdoors and sample the biodiversity of plant species in natural and cultivated areas. Then they compare the biodiversity of plants in the natural areas to […]

Investigating Phenomena: How Is the Silver Formation Explained?
Carolina Phenomenon Phenomena-driven science! Phenomena are observable, naturally occurring events that are everywhere and spark student questions and investigations. Ask students to observe the DCI-linked phenomenon in the video and complete the attached student sheet prior to remote learning discussions. Observations: Carefully watch the copper wire and silver nitrate solution video. Gather all the evidence you can […]
Cooking Eggs with Chemicals
A demonstration of denaturing protein Introduce high school biology and chemistry students to the concept of denatured proteins with this inexpensive, fun demonstration. Your students will be amazed when you “cook” an egg in hydrochloric acid, and they will learn that a protein (egg white) can be denatured by heat, or, as shown in the […]
Single-replacement Reaction
Create silver decorations with chemistry In this activity students perform a redox reaction in which silver take the place of copper in copper wire. The copper changes from its elemental form to its aqueous ionic form. During the course of the reaction, the silver ions are reduced and are removed from the solution. The silver […]
