Temperature Changes in Dissolving
Alia-Seltzer tablets cause a very obvious chemical change, but do they also cause a temperature change? Each class member explores hot/cold packs, discussing how these temperature changes occur. Groups then design and carry out their own...

Chemical Formulas Unit-Day 4
The purpose of this lesson plan involves reviewing nomenclature and molecular
formulas as well as introducing naming molecular compounds and identifying acids. The students investigate and understand how conservation of energy
and matter...

Polymers
Students explore online tutorial on polymers. In this chemistry lesson, they create two polymers in the lab and compare their properties. They write a sales letter about their new and improved polymer product.

Writing Chemical Formulas
Students study how to write chemical fomulas by reviewing the combinations atoms form into compounds. They write a procedure to test various substances and name the compounds and write formulas. As they construct models for formulas and...

Float or Sink?
Experiment with mass and density as scholars figure out what makes things float or sink. First, they watch a podcast introducing these concepts. Be sure to use the comprehension question to test their understanding. Young scientists...

WS 7.2 Kinetic Theory-Temperature and Volume
In this kinetic theory worksheet, students answer questions about kinetic energy, they calculate volumes of gases at STP, they answer questions about temperature and they convert from one unit of temperature to another.
Curated OER
An Introduction To Material Sciences
Students investigate the concept of molecular structure. They describe the behavior of simulated molecules and identify any dislocations in crystalline structures. They also define various related vocabulary words and use them in...
