"Arsenic and Old Waste": Groundwater Activities Using Modeling

Biotechnology pros produce their own biofuel using waste oil and fresh vegetable oil. They test the quality of their product using titration techniques and pH analysis. They write their observations and report their findings. Be aware...

How can December 21 be the shortest day of the year when all days are 24 hours long? Pupils see how to build a model showing the differences between winter and summer solstices and equinoxes. Using this model, classes can then discuss...

It's a jungle out there! Young biologists journey to Darien, Panama to examine the intricate relationships between the organisms that inhabit the jungle. Groups begin by demonstrating an understanding of energy flow in ecosystems, then...

What does the past have to do with today? Young scientists find that answer as they learn more about past chemists and their significant contributions to the field. Pupils use the Internet to research historical figures...

The atom has come a long, long way! From its early days as a ball of goo that exhibited the same properties as the whole it was part of, to the tiny sphere we know today, atomic theory has truly evolved. Explore these changes with an...

How do you plan to approach standard LS1C, Organization for Matter and Energy Flow in Organisms? Avoid information overload with helpful advice in a short video. Topics include energy sources, relationships between organisms, and...

Describes the serious global waste crisis, the problem of plastic waste, the issue of wealthy countries exporting their trash to less-developed ones, informal waste management practices, and electronic waste dumps. The article ends with...

Collaborative earth science groups create a working model of a watershed. Once it has been developed, you come along and introduce a change in land use, impacting the quality of water throughout their watershed. Model making is an...

Students create a paper model to illustrate sea-floor spreading.

This project shows you how to build a simple model system to simulate underground water flow. Underground water flow is important for understanding replenishment of underground aquifers, migration of underground contaminant plumes, and...
