Leaf Classification
The purpose of this resource is to develop a classification system for a set of objects and learn about hierarchical classification systems. Any set of objects, such as insects or rocks, may be used as well.

Soil Characterization Protocol
The purpose of this resource is to characterize the physical and chemical properties for each horizon in a soil profile. Students identify the horizons of a soil profile at a soil characterization site, then measure and record the top and bottom depth for each horizon. For each horizon, students describe the structure, color, consistence, texture, and abundance of roots, rocks, and carbonates. Samples are collected and prepared for additional laboratory analysis.

In this lab, students use dice to simulate radioactive decay. Students create a standard decay curve for a fictional element, calculate the half-life of this element, and, using the information their graph, "date" rocks that contain the new element. The use of dice has some advantages over similar exercises because the half-life is not immediately obvious to students and they will need to experimentally determine it. Learning goals, context for use, teaching tips, materials, assessment tips and

Density of Rocks - How Large Is a Ton of Rock?
This module addresses how to determine the size of a ton of rock of a given composition and invites the student to figure out how to solve the problem. Students recreate spreadsheets, shown in a Powerpoint module, on their own with formulas that answer various pieces of the overall question. This module is the third in a series of six that examine the density of planets and rocks, and was designed for an undergraduate class where students look at geological questions mathematically and may spend

Oobleck
Developed for first grade. Students will make a substance and use scientific observations, as well as their senses to classify Oobleck and its ingredients as solid, liquid, or gas. Students will notice that Oobleck bounces and is very tangible, but also very gooey and slimy all at the same time. Students will be amazed how Oobleck can fit so many different categories. Students will love playing with Oobleck after taking pride in making it! Biology In Elementary Schools is a Saint Michael's Coll

Electric Field Hockey
Play hockey with electric charges. Place charges on the ice, then hit start to try to get the puck in the goal. View the electric field. Trace the puck's motion. Make the game harder by placing walls in front of the goal. This is a clone of the popular simulation of the same name marketed by Physics Academic Software and written by Prof. Ruth Chabay of the Dept of Physics at North Carolina State University.

Minerals, Crystals, and Gems: Stepping Stones to Inquiry
This site introduces students to mineral science and the scientific process -- observing things, forming hypotheses, and drawing conclusions. Students watch crystals grow, go on a scavenger hunt for minerals, and create a classroom exhibit of rocks and minerals (for Grades 3-8).

COSEE Great Lakes Workshops
These asynchronous workshops focus on environmental topics related to the Great Lakes region. Subjects covered include: The solid earth system; The bedrock and formation of the Great Lakes; Life and Rocks: Current geological processes; Human impacts [vice-versa!]; and Ocean/lake deep exploration (sink holes, underwater archeology, NOAA's exploration book) studying the bottom, characteristics of the water at depth.

Resistan
Resistan is a mechanistic simulation model of the process of selection of fungicide-resistant biotypes of a hypothetical fungal pathogen of a hypothetical crop. The fungus is a polycyclic organism with many generations per season. There is no genetic component in this simulator. Reproduction is assumed to be asexual. A small proportion of the initial inoculum is designated as the fungicide-resistant biotype at the start of the season, and the response of that population to various fungicide spr

Scaffolding: A model for learner support in an online teaching environment
'In the design of online teaching environments, considerable attention has been paid to the nature of the interface and to the streamlining of activities for learners to engage with. Much less attention has been given however to the nature of the learner support system that is created for novice users learning online. Support systems are essential for learners to engage in the processes of learning and need to be developed in response to needs. It is also imperative that a range of support syste

Reflections on Playing Ayiti: The Cost of Life
Ayiti: The Cost of Life is a role-playing video game in which the player assumes the roles of family members living in rural Haiti. At the start of the game, the player chooses a primary goal for his/her family: achieve education, make money, stay healthy, or maintain happiness. During the course of the game, the player encounters unexpected events and must make decisions that contribute to or detract from achieving the chosen goal. After students have played the game they will need to reflect u

Graham Farmelo on Paul Dirac and Mathematical Beauty
Adjunct Professor of Physics at Northeastern University in Boston, Graham Farmelo, on Paul Dirac and the Religion of Mathematical Beauty. Apart from Einstein, Paul Dirac was probably the greatest theoretical physicist of the 20th century. Dirac, co-inventor of quantum mechanics, is now best known for conceiving of anti-matter and also for his deeply eccentric behavior. For him, the most important attribute of a fundamental theory was its mathematical beauty, an idea that he said was "almost a re

Essential Science for Teachers: Earth and Space Science: Session 2. Every Rock Tells A Story
How can we use rocks to understand events in the EarthÂ’s past? In this session, participants explore the processes that form sedimentary rocks, learn how fossils are preserved, and are introduced to the theory of plate tectonics.,Students and scientists explore the questions: How do rocks form? How can we determine how old rocks are?

Essential Science for Teachers: Earth and Space Science
In-depth interviews with children that uncover their ideas about the topic at hand.,The interviewer shows the student two different representations of mountains, one smooth and one jagged, and asks her to describe what she sees. As she describes a volcano, the interviewer probes to find out why she thinks it is a volcano, whether a volcano is a mountain, and how a volcano forms a mountain.
