In this life science field investigation students will study golden rod gall populations within a patch of goldenrods.

This activity is a mock investigation into different macroinvertebrates found in the streams in your local city. Students will record and analyze data that will lead them to learn if the water quality is good or bad in their backyard.

Students set up and run the experiments they designed in the Population Growth in Yeasts associated lesson, using simple yeast-molasses cultures in test tubes. Population growth is indicated by the amount of respiration occurring in the cultures, which in turn is indicated by the growth of carbon dioxide bubbles trapped within the culture tubes. Using this method, students test for a variety of environmental influences, such as temperature, food supply and pH.

This activity is a field investigation or bio-blitz where students are collecting as many different types of insects as they can. Back in the lab, they will record their findings, sort and classify the insects found. This will lead into a class discussion on biodiversity and the importance of insects and their benefits all living things.

This activity is a lab where students learn to classify objects that are similar into groups and technically describe their classifications. Introduction to dichotomous keys.

This activity is a project in which students research keystone species and report on specific species to the class.

This field and classroom activity involves identification of similarities, differences, advantages, and disadvantages in survival, method of locomotion, food acquisition, and reproduction in three fresh-water microbes.

This activity is a classroom lab where the students gather data on the affect water has on gummy bear candies and develops an experiment based on a new question regarding a not plain water solution. Students will perform calculations and graph their results.

This guided inquiry is a laboratory investigation on soil textures where students gather and analyze data, compare findings and develop new experimental questions.

In activity is a Biology field lab where students will investigate the relative health of an aquatic system based on bioindicators. Students will then summarize and reflect upon their findings.

This activity is based on observations of mealworms form a question and make decisions as to the design of an investagation. Students use data collected to make a conclusion to their questions.

This activity is a combination of a field investigation and direct instruction at Minnehaha Falls. We are investigating Twin Cities rock types and weathering from the flowing water.

Through two lessons and five activities, students explore the structure and function of cell membranes. Specific transport functions, including active and passive transport, are presented. In the legacy cycle tradition, students are motivated with a Grand Challenge question. As they study the ingress and egress of particles through membranes, students learn about quantum dots and biotechnology through the concept of intracellular engineering.

In this lesson, students will extend their knowledge of matter and energy cycles in an organism to engineering life cycle assessment of a product. Students will learn about product life cycle assessment and the flow of energy through the cycle, comparing it to the flow of nutrients and energy in the life cycle of an organism.

In this biology field experience, students will explore trees of Minnesota. Working in cooperative groups, students will discover biodiversity of trees and determine populations of tree species through observation and use of dichotomous keys.

This activity is a longer project that involves using inquiry to find out what kinds of aquatic animals live in our school pond. Students use direct observation, journaling, outdoor classroom techniques, research skills, collaboration, and service learning to learn about their question.

This activity is an investigation where students observe cells from various organisms and then compare and contrast the cells they observe.

This is a classroom activity in which students observe and describe cells in stages of division. They share observations about what they see in the cells, then formulate questions and do research concerning the changes that take place in cells during the process.

This lesson covers the process of photosynthesis and the related plant cell functions of transpiration and cellular respiration. Students will learn how engineers can use the natural process of photosynthesis as an exemplary model of a complex yet efficient process for converting solar energy to chemical energy or distributing water throughout a system.
