Bug Hunt uses NetLogo software and simulates an insect population that is preyed on by birds. There are six speeds of bugs from slow to fast and the bird tries to catch as many insects as possible in a certain amount of time. Students are able to see the results graphed as the average insect speed over time, the current bug population and the number of insects caught. There are two variations to try for the predator, one where the predator pursues the prey and one where the predator stays still and captures insects that pass nearby. In the first case the bird catches the slow insects and the faster ones survive, reproduce and pass genes on. The average speed of bug should increase over time. In the second case the faster bugs come near to the bird more often than the slow ones. The slow ones survive more, reproduce and pass their genes on.

How can we design buildings to withstand an earthquake? This activity uses simple materials and gives learners a chance to experiment with structures that can withstand an earthquake. Two optional activities explore building damage by subjecting models to ground vibration on a small shake table.

Bring the rainforest to life in your classroom! Give your students hands-on experiences that will build their understanding of the importance of tropical rainforests and the need for protecting these valuable ecosystems. Explore topics including the water cycle in the Amazon, the life cycle of rainforest plants, rainforest conservation challenges, and more. You can use this kit to prepare your students for a field trip to the Academy's Rainforest Exhibit. Or, if you can't make it to the Academy, use the kit on its own to bring the rainforest to you! This version of the rainforest kit is for grades 4 - 8.

Lab 1: the students begin by describing on a worksheet their own ideas of delta formation using concept sketches and written descriptions of the stages of formation, with only broad guidance from the instructor. They are also asked to describe the key features of their concept sketches, and to hypothesize how those features might develop (the processes). The students have all been exposed to deltas in Physical Geology, but likely only have rudimentary knowledge of them. Once they have completed the worksheet, the entire class moves to a lab with a stream table in it, preset to run a "model delta." The model has both a web cam and a time-lapse web cam set up over the table to record the development. The students help start the water flowing and the cameras recording, then watch as it develops over the next 2-3 days.
Lab 2: In the second lab, we use grain-size analysis of the stream-table delta as a means of testing some of their ideas from lab 1. The students as a class develop a strategy to sample the stream-table delta for grain size, using a laser grain-size analyzer. Each pair of students collect one sample, but are also asked to predict the changes in grain size distribution for samples elsewhere in the delta. The particle size analyzer rapidly provides results to the students near the end of lab.
Lab 3: the final lab is a field trip to a pair of gravel pits that expose the guts of two natural stranded deltas, including topset and foreset beds. The students are asked to assess the landforms on a topo map before arriving, and to describe the deposits at each site we visit. On the final writeup, the students need to synthesize all the elements of the three labs, along with input from our readings in the textbook (Easterbrook) and McPhee's "Control of Nature."��

In association with rock and mineral ID tables, this lab introduces students to basic rocks and minerals via grouping and comparison, rather than as individual samples. I use this lab in my environmental geology course, where we don't have enough lab time to examine each set of rocks and minerals separately, but students need a basic familiarity with these materials and a context in which to place them. I find these groupings teach them how to look at rocks and minerals and give them the cursory experience identifying geologic materials necessary to go on successfully in the course.

At the beginning of a course-based research project, each student in a research team is asked to read primary literature related to the team investigation. A mix of provided readings and readings found by the students builds the team content knowledge concurrent with team work on research design and data collection. Students reflect and report on the readings in an annotated bibliography, which is a graded assignment in the course.

This assignment, depending on the level and depth of implementation, seeks to challenge students by asking them to look beyond "greenwashed" advertisements and buzzwords to grapple with what sustainability means, whether it can be achieved, and what kinds of questions communities must confront in a search for sustainability.

Students build a stratigraphic column for a pre-selected area through the compilation of a series of individual research projects. Students are required to conduct introductory field research as well as a literature search to become "experts" on a selected stratigraphic unit. In addition to a final report, students will present their information at an outcrop on an end-of-semester field trip.
