Challenge your classes to complete an experiment from beginning to end. Learners make their own hypotheses, collect and analyze their own data, and make their own conclusions. They are on their way to becoming statisticians! 

How is it possible for ocean water to have layers? The sixth installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program investigates factors that cause different water densities to occur. Experiments...

Think like an engineer and an agricultural scientist over the course of 12 lessons in a STEM based unit. Young scientists take on the roles of animal physiologists, animal geneticists, agricultural engineers, animal nutritionists,...

Before iPhones and calendars, how did humans determine the seasons of the year? Middle school scientists discover how to use shadows to determine the time of year in an enlightening interactive. Pupils manipulate the sun and examine the...

Even the creepy crawlers have pretty amazing anatomy! A thorough lesson describes characteristics of arthropods with an emphasis on their structures. Beginning with a review of the taxonomy hierarchy, the lesson explains the different...

Who actually likes leeches? Meet a scientist that makes his living letting leeches feed on him. Pupils learn about the characteristics of leeches and different variations of the species. The lesson works as a remote learning resource or...

Students create a geologic map and cross-section of an area of horizontal sedimentary rocks, exposed in several locations. Map must include a complete key or legend with rock descriptions of the various formations.

Students study how to calculate momentum, kinetic, and potential energy. They apply each form of energy to real world situations including demonstrations, watching videos, and designing a Power Point presentation. They investigate in...

Eighth graders, in a computer lab, transform their images into a full face using the paint & draw tools.

Students participate in a research project that is exclusively using the internet. The author states that traditional labs are hard to conduct for a light lab. This one uses the internet with the intention that students can manipulate...
