Learners observe how different water densities control the depth at which different water masses occur. They explain one fact that they comprehend about salt water. Students comprehend that temperature and salinity affect the density...

Students explore Boyle's Law. In this Boyle's Law lesson, students complete problems involving Boyle's Law. They examine the effects of Boyle's Law upon the human body. Students use the Internet to complete a lab activity.

Learners examine the environmental impact of global warming. In this environmental science instructional activity, students design and conduct an experiment about the effect of temperature on paramecia. They write a lab report about...

Middle schoolers explore heat energy and how it is used to change the phase of matter, and discover that temperature does not increase or decrease until the phase change is complete. This extremely well-written plan is packed with great...

Students examine what happens when air temperature drops and gets closer to the dewpoint. They perform a lab activity which illustrates the effects on humidity, precipitation and barometric air pressure.

Seventh graders investigate scientific methods to solve problems. They demonstrate creating data tables and graphs. They study the role of a scientist and the importance of safety in a science lab. They distinguish between an...

Students research the International System (SI) of units of measurements. They make measurements using the metric system. They study key concepts used in building and use of sensors, how sensors work and their role in measuring...

Students recognize both a physical and chemical change in different substances. They determine which particles actually changed into different substances, and explain if it represented a physical or a chemical change.

Students design an investigation to test whether vegetation in an area helps regulate the ambient air temperature. They make comparisons between the investigation and global changes in climate. In groups, they present their findings to...
