Detecting Magnetic Materials in "Martian" Soil
Students simulate some of the Pathfinder experiments by devising methods of collecting and measuring magnetic substances in pseudo-Martian soil. The efficiency of each of the methods used to collect materials is evaluated in this...

ME402: Growth of Yeast
Students investigate the growth of yeast in a sugar solution. They verify the pressure of carbon dioxide using bromothymol blue. Students are asked to describe the difference between the contents of the test tubes used and to explain...

pH Potential
Pupils experiment to determine the positive and negative impacts of human activities on environmental change. They examine how physical and biological processes such as decomposition affect soil characteristics while looking at the pH of...
Curated OER
Reflection and Absorption of Light
Students use a microcomputer connected to a light sensor and temperature probe to explore the reflection and absorption of radiation for different surfaces. Students follow instructions in this guided inquiry based lab and are then asked...
Curated OER
Reading the River
In collaborative groups, young ecologists measure the temperature, pH, and dissolved oxygen for three different freshwater samples. They examine each sample with a microscope and record observations on the microorganisms in the pond...

Seeds of Wetland Life
Learners participate in several activities on seed exploration. For this biology lesson, students classify seeds according to their dispersal method. They explain the different adaptations plant have to disperse their seeds.

Looking At Acid's Effects On Metals
Students perform an experiment that demonstrates acid rain. The chemical effect of acids on metals may take at least five days for the human eye to see, even though the reaction starts as soon as the acid contacts the metal.

Rocks, Minerals, and Erosion
Fourth graders describe the difference between minerals (composed of the same substance throughout) and rocks (composed of two or more minerals). They recognize that there are three classes of rocks: igneous, sedimentary, and metamorphic

Eco-Logical: A Coastal Logic Problem
Fourth graders study the characteristics of five coastal communities. They use logic cards and matching activities to identify the proper community for plant and animal species.

Ecology
Sixth graders are introduced to online research and beginning PowerPoint presentations that are integrated. They pass a plant and photosynthesis. Students locate information on a self selected animal online. They give a PowerPoint...

Map Reading
After examining a map from 1803 and 2003, they explore how to become map readers. They describe what they see on the map from 1803 and compare the information to the map from 2003. Learners create their own map of the neighborhood that...
