Up, Up and Away
Third graders are presented with the problem of: Do all liquids evaporate at the same rate? The lesson contains adequate background information for the teacher. They participate in a lab experiment in order to test the scientific...
Curated OER
Evaporation of Alcohol and Water
Students investigate the process that occurs when liquids evaporaate. They test water and alcohol to determine which substance evaporates more quickly and relate the rate to energy changes.
Curated OER
The effect of hunger on children and graphing
Students research the effects of hunger on society. In this Current Events lesson, students create a graph to present their findings.
Curated OER
Math: "Scales"
Third graders investigate ratios and rates. In this third grade mathematics lesson, 3rd graders identify equal ratios and rate and test for proportionality. This lesson is created to be use in conjunctions with a particular textbook,...

Camp Chase Confederate Cemetery
Students use maps, readings and photographs to locate prisoner of war camps in the North during the Civil War. They identify the camp's population sizes and mortality rates and how the camps' uses have changed over time.
Curated OER
Canned Heat
Students demonstrate that light and dark colored objects absorb the sun's radiation at different rates. They experiment with the temperature change of water in two locations and discuss the results.
Curated OER
Sediment Tubes
Students observe how different density soils and rocks behave in wind and in water. They make predictions and careful observations as they explore sediment transport and sediment rates in streams and rivers.
Curated OER
Half-Life Lab
Learners participate in a lab in which they are introduced to carbon-dating. In groups, they use the holes of paper from a hole puncher and determine the rate of retention after shaking coins onto the same area. They record their...
Curated OER
Death and the Deerfield Graveyard
Students learn how death is an indicator of the community beliefs and values, and how have the rituals surrounding death changed over time.
Curated OER
Environmental Differences
Young scholars observe and conduct an experiment to see whether differences in salinity (the environment) have an affect on the hatching rate and survival of brine shrimp.
Curated OER
The Great Gas Race
Fourth graders improve their understanding of Graham's Law by using properties of gases to evaluate the rate of effusion of two compounds as they vaporize. They engage in a lab which elevates their understanding of the properties of gases.
Curated OER
Let's Settle It!
Students investigate and record data about sedimentation rates. They make a sedimentation bottle using aquarium gravel, sand and potting soil. They discuss the sedimentation rates that they see in their bottles.
Curated OER
The Effects of Environment on Plant Growth: Selecting Seeds for Survival on a New Planet
Fifth graders conduct experiments to compare seed germination and plant growth rates. They construct a hydroponic plant unit and a lighthouse. They care for the plants for a month and collect data for graphs. They write a report.
Curated OER
Scientific Approach to Forest Management
Young scholars use wireless laptop computers to collect, store, communicate, and organize data from the 1999 Jasper Fire area. They collect data in the field and compare it to student-collected data from prior years to develop...
Curated OER
Seeds and Similarities
Students use the scientific inquiry method to identify the changes in a plant's life cycle. In groups, they plant different types of plants and use a chart to compare and contrast their growth rates. They share their conclusions with...
Curated OER
Erosion
Fifth graders study the effects of running water on erosion. They examine how the soil on the playground is affected by erosion and determine how the placement of trees and shrubs changes the path of erosion. In their science journals,...
