Facilitate learning by using small objects to teach the principles of atomic mass in your science class. Pupils determine the average mass of varying beans as they perform a series of competitive experiments. They gather data and...

High schoolers explain the basic properties of a watershed including how water flows from higher to lower elevations and how watersheds are interconnected. They comprehend how the placement of buildings, roads, and parking lots can be...

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,...

In a simulated crime science investigation, chemistry or physics sleuths use spectroscopy to analyze solutions. The lesson gives learners practice making salicylate solutions, using spectrophotometers, calculating dilution amounts,...

Students conduct qualitative and quantitative investigations based on the interaction between water and various polymers. They determine the percent moisture contained in various plastics along with a qualitative procedure to determine...

Students participate in lab activities in which they examine immersion, stain resistance, and stress cracking of synthetic polymers. Students use their collected data to discuss service applications and possible performance of materials.

Students design an experiment to evaluate the effects of various treatments on the nitrogen cycle in a freshwater aquarium. They are required to maintain a laboratory notebook of all work, measure the key analytes of the biosystem at...

Investigators collect the carbon dioxide produced when an antacid tablet is activated and identify what alteration produced the most gas. They also collect the gas in a buret in order to practice precision. Then they choose between two...
