Causal Patterns in Density Phenomena

There's a lot content packed into the four lessons of this physical science unit on density. From salad dressing to the water cycle and hot air balloons, these lessons engage students in hands-on activities that explore real-world...

Focus on inquiry-based learning in your science class with a series of activities designed for middle schoolers. A helpful packet samples four different texts, which include activities about predator-prey relationships, Earth's axis and...

Investigate the fascinating, yet terrifying phenomenon of hurricanes from the safety of your classroom using this earth science unit. Focusing on developing young scientists' spacial thinking skills, these lessons engage learners in...

A multi-faceted and exciting activity awaits your astronomy students. In collaborative groups, they plan a mission to hunt for extraterrestrial life within the solar system, while adhering to specific measurement criteria. 

It's getting hot in here! Lead your emerging geoscientists on a thrilling journey as they calculate liquid densities to determine forces that stimulate thermal plates from within the earth's crust. They explore effects of temperature on...

Close reading doesn't mean to literally read text close to your face, but rather to pay attention to particular details in order to develop a deep and purposeful understanding of text. The first part of a five-part resource provides an...

Graphs might be everywhere — billboards, magazines, newspapers, and ads on the Internet — but that doesn't make interpreting them easy. Learners use numerous sources of weather data to construct and analyze graphs, looking for patterns...

Students set up working models demonstrating lake turnover and the formation of deep water masses in the oceans.

Mass and density — aren't they the same thing? This activity has groups use balance beams and water displacement to measure several objects. The pupils use the measurements to calculate the density of the objects. 

Groups suspend objects within layers of liquids to determine the densities of different liquids and compare them to the densities of objects calculated in Part 1. The groups then carefully test their calculations by layering the liquids...
