B. "Exploring the Secrets of Sugar & Salt" Activity Book, English
SKU: SSABEN
In the first section of the unit, youth explore where on theirtongue they taste each of the five known tastes. In the next two activities, they learn how to read food labels for sugar and salt content. They then consider how much sugar and salt they eat and compare it to what is recommended.
In the second part of the unit, the youth delve into the chemistry of solutions. They investigate what it means for something to disolve and what factors influence that process. They also see that the process of disolving can be reversed to form beautiful salt crystals. Finally, they explore the concept of density as they create liquid rainbows using colored sugar solutions of different concentrations.
In the final section of the unit, the youth take a look at the effect of salt on the freezing point of water. They even use their new found knowledge to make ice cream! They also examine the environmental effects of using salt to melt icy roads. They see the effect of salt on plants and then consider what chemical they think should be used to keep roads free of ice.
