Students will utilize factually observed or researched information in a creative high interest-writing project.

This lesson plan provides the teacher with an activity to help students calculate the Greatest Common Factor of two or more positive integers and develop a definition based on their exploration. Students find the prime factorization of two positive numbers using factor trees and Venn diagrams to sort the prime factors. The plan includes learning objectives, materials needed, questions to ask students, assessment options, extensions, teacher self-reflection questions, and further references.

In this activity, students take the age old concept of etch-a-sketch a step further. Using iron filings, students begin visualizing magnetic field lines. To do so, students use a compass to read the direction of the magnet's magnetic field. Then, students observe the behavior of iron filings near that magnet as they rotate the filings about the magnet. Finally, students study the behavior of iron filings suspended in mineral oil which displays the magnetic field in three dimensions.

The activity walks the students through the processes of Photosynthesis and Cellular Respiration.

This activity provides students with a first look at water tension and its role in the life of a water strider.

Prepared with pre-algebra or algebra 1 classes in mind, this module leads students through the process of graphing data and finding a line of best fit while exploring the characteristics of linear equations in algebraic and graphic formats. Then, these topics are connected to real-world experiences in which people use linear functions. During the module, students use these scientific concepts to solve the following hypothetical challenge: You are a new researcher in a lab, and your boss has just given you your first task to analyze a set of data. It being your first assignment, you ask an undergraduate student working in your lab to help you figure it out. She responds that you must determine what the data represents and then find an equation that models the data. You believe that you will be able to determine what the data represents on your own, but you ask for further help modeling the data. In response, she says she is not completely sure how to do it, but gives a list of equations that may fit the data. This module is built around the legacy cycle, a format that incorporates educational research feindings on how people best learn.

In this video segment, adapted from a student video produced at Northwest Indian College in Bellingham Washington, Native American elders discuss the impact of climate change on salmon populations and the importance of restoring balance in the natural world.

This video documents the challenges that climate change presents for four specific Arctic predators: polar bears, Arctic foxes, beluga whales, and walruses.

In this video segment adapted from the College of Menominee Nation, learn about the emergence of invasive forest species and diseases and their possible impact on the Menominee tribal forest.

Focuses on the geotechnical aspects of hazardous waste management, with specific emphasis on the design of land-based waste containment structures and hazardous waste remediation. Introduction to hazardous waste; definition of hazardous waste, regulatory requirements, waste characteristics, geo-chemistry, and contaminant transport. The design and operation of waste containment structures, landfills, impoundments, and mine-waste disposal. The characterization and remediation of contaminated sites, the superfund law, preliminary site assessment, site investigation techniques, and remediation technologies. Monitoring requirements.

This lesson helps grade 3 students understand the difference between Vertebrates and Invertebrates.

Students discuss several human reproductive technologies available today pregnancy ultrasound, amniocentesis, in-vitro fertilization and labor anesthetics. They learn how each technology works, and that these are ways engineers have worked to improve the health of expecting mothers and babies.

The activities in this Illumination lesson plan deal with patterns and the importance of looking at an object/item from more than a single perspective and reaffirms to learners that numerous reasonable solutions are possible. Students investigate a series of items (a list of class names and a parade of animals) that appear to be ordered in some "obvious" ways and also explore ways of sorting items ( a deck of cards and numbered horses) into two disjoint groups on the basis of some definable characteristic. Activity sheets are included in pdf format.

In this activity students examine karyotypes from five individuals to try to identify which chromosomes determine gender in humans. This activity is also a good illustration of meiotic non-disjunction.

a. This activity is designed for students to work on their observational skills, and the communications of their observations. They will also learn to pose researchable or testable questions, to give critique (and to receive) critique on their comments and research.

In this investigation, students will design experiments and gather data to observe the factors that influence the activity of enzymes.

This static image from NOAA's Pacific Marine Environmental Laboratory Carbon Program offers a visually compelling and scientifically sound image of the sea water carbonate chemistry process that leads to ocean acidification and impedes calcification.

Students will listen to the book, Under One Rock Bugs, Slugs, and Other Ughs, written by Anthony D. Frederick and illustrated by Jennifer DiRubbio and then make a mini-book observation journal, Under One Rock to record what they see when they go outdoors to investigate what lives under a rock.

Students will use this activity to determine what keeps our bones strong. Soaking the bones in vinegar will remove the calcium from the bones causing them to become soft and rubbery. Students will find that when we age, calcium is depleted from our bones faster than we can restore it. They will then determine what complications can arise from it.

Spreadsheets Across the Curriculum module. Simulating a forensic calculation, students build spreadsheets and create graphs to find the time of death of a potato victim from temperature vs. time data.
