Properties of Salt

Investigate how temperature affects the density of water and stratification that occurs in bodies of water when temperatures vary. Water of differing temperatures is given different colors to see the layers that form. The lesson is meant...

Crystals are more than meets the eye! Can learners tell them apart simply by observation? As they examine five samples with a magnifier, they find that appearance alone is not enough. This serves as an introduction to a mini unit on...

Make sure to consult the teacher's handbook, Inquiry in Action - Investigating Matter Through Inquiry, for two demonstrations that can be done to introduce solubility and measuring crystal mass before having the class conduct this...

Of quartz I love geology! The chapter offers five activities at three different levels. It features hands-on activities that cover crystal shapes, cleavage and fracture, hardness scale, specific gravity, and mineral identification....

It is impossible to cool down a glass of water by adding ice. Young scientists explore heat transfer through videos, experiments, and interactive games. They quickly catch on that the water melts the ice and things aren't always as they...

Differentiate between temperature and thermal energy. Your class will build a thermometer using simple materials and develop their own scale for measuring temperature. Discuss with your class and consider why engineers need to understand...

This isn't just an art lesson, it's a science lesson too. Kids draw a lovely winter scene and then paint over it with a solution of epsom salts and water. They make predictions, then observe how crystals form as the water evaporates...

Now it becomes crystal clear why the unit is called Mixtures and Solutions. The fifth installment of a six-part unit explores mixtures and solutions. After viewing a demonstration on mixing pebbles with water, salt with water, and...

As an anticipatory set, young environmental technicians watch a video about how ocean temperatures seem to be changing along with the global climate. They perform a laboratory demonstration with the purpose of observing what happens to...

Take part in a fun experiment and hold an impromptu bouncing contest with your class. Young scientists heat and cool balls before bouncing them to determine whether temperature changes affect how they bounce. The set of STEM lesson plans...
