One in a Million

In preparation for solar car races, middle schoolers attempt to discover what time of day the most solar energy can be collected. Begin by demonstrating the use of a voltmeter for measuring solar cell output. Take them outdoors to take...

Water may appear to be crystal clear, but there could be dissolved substances present. Lab groups make a one-part-per-million of a food coloring solution to demonstrate this concept. As part of an outstanding unit about water, this...

Is there medicine found in the organisms that live deep below the surface of the ocean? The fifth lesson in a six-part series has learners team up to research bacteria and the relationship it has with nearly every living thing on Earth....

Throughout history, the growth of big cities has resulted in the destruction of ecosystems. In the case of Chicago, IL, a grassland that was once home to bison, deer, wolves, and foxes quickly became a booming city of over three million...

Substances dissolved in water can be present in very tiny amounts that are not visible to the eye. in this lesson learners make a solution of food coloring with a concentration of one part per million.

In this KWL chart worksheet, students fill in this graphic organizer about living and non-living things. Students complete 3 sections in the chart.

The 3 steps of the water cycle, evaporation, condensation, and precipitation, are the focus of this lesson. After a neat demonstration of rain using hot water, a pie tin, and ice cubes, young scientists observe and discuss the elements...

To develop an understanding of parts per million as a concept, teams of students create successive dilutions of a solution to reach a parts-per-million concentration.

Students explore plant life. In this science lesson plan, students demonstrate and record the stages of plant growth and categorize food plants by identifying the edible part.

Fifth graders investigate concentrated and diluted solutions by conducting a taste test.  In this dilution lesson, 5th graders examine the concentration of different juices samples by tasting them and recording their observations....
