Students use scientific methods during field and lab investigations. Students collect specimens and make measurements using the metric system. Students describe biotic and abiotic factors in an estuary and design a model.

Students investigate rocks and minerals and take a field trip to sample soils. They analyze rocks and soil, research the geological terrenes of the topology of San Francisco, and produce a lab research report.

Students examine how an estuary's plants and soil filter water before it flows into the ocean. They complete a lab report drawing and writing about what they observe after completing a water filter activity.

Learners describe safe practice when doing field and lab investigations in a estuary or wetland. They create a model of an estuary and describe their value and function. They participate in field study in which they collect and analyze...

Students work together to research water quantity, quality and safety standards. They complete a lab to discover how to use the water from an air conditioner. They write a paper to show their findings.

Students are introduced to the topic of electromagnetic induction. In groups, they describe ways in which the magnetic flux can change and discuss emf and current. They use different scientists laws and apply it to various scenerios in a...

Young scholars examine how mining and other industry operations can lead to acid runoff.  In this mining lesson students study weathering and complete a lab on it. 

Students discover how toys often illustrate fundamental physical principles. The toy drinking bird is an example. The challenge for you in the lab is to discover why the drinking bird functions.

Learners examine diversity on the planet and the differences within a species.  In this investigative lesson students complete a lab that allows learners to better understand the relatedness between plants. 

Students practice the proper lab techniques of coring, seining, taking temperatures, and salinity. Students analyze and graph data. Students write a 3 part essay and correctly draw and label a food web of their field site.

Young scholars use this introductory lab using a tennis racquet, however it is very difficult to study because of the strings and the racquet stretch so little and so quickly during a match that students were unable to make simple...

Students review the parts of fabric, good fabric selection for a quilt, and participate in a lab to determine a good fabric for quilts. They identify the parts of the fabric, how important the parts of the fabric are, and select good...
