Benedicts mixture A, benedicts B, starch, glucose, absorbic acid, indophenol, protein, test tubes, droppers, instructions and background materials. Grades 5-9.
Students will test the physical properties and investigate the chemical composition of carbonated sodas. Then they'll formulate hypotheses, checking their predictions with experiments that they design and conduct themselves. In the process, they'll reveal the composition and nutritional value of various sodas. Enough for 40 Students.
Two commonly used drugs, aspirin and antacids, will be analyzed separately. After investigating samples included in kit, students can select brands of their own choice for additional comparison. Grades 9-12.
Using comprehensive, curriculum-based investigations, your students will learn about the metric system, mass, volume, density, gravity, temperature and pH. Through these activities, the class gains a thorough understanding of how to gather information, graph and analyze data, and interpret scientific diagrams. Grades 7-10.
Your students will become junior detectives, honing their forensic skills by solving the mysteries surrounding a fictitious "crime scenario". They'll conduct a series of forensic analysis activities to determine if a crime has been committed. Each activity is centered around a particular analysis technique to include toxicology, chromatography, finger printing, document analysis and simulated blood typing.
Visualize the potential contamination of groundwater. Construct mini-groundwater simulation models showing the movement of a simulated, colored pollutant. Determine under what conditions contamination occurs from a variety of sources such as spill, farms, and buried tanks and how polluted groundwater eventually reaches the drinking water supply. In the process, students learn about the water cycle, water quality, ppm and ppb pollutant contamination, porosity of soils, and other related concepts. Grades 6-10.
Observe the use of microbes for oil degradation. Model various spill scenarios and monitor the effectiveness of the provided freeze-dried oil-degrading microbe mixture in remediating the waste. Set up a simulated oil spill in water and treat it with the special microbial product to observe the physical changes degradation of oil film over time. Additionally, they simulate three spill scenarios on beach sand, gravel and cobbles in order to observe the difference in degradation rates. The class also explores bioremediation methods for other waste chemicals and compares their effectiveness to traditional clean-up methods. Grades 7-10.
Introduce your students to the fundamentals of chemistry. Provide your class with a basic understanding of the primary concepts of chemistry as they investigate how matter is classified, identify the various types of mixtures, and compare the properties of solutions with the properties for mixtures. They'll also learn to identify elements and compounds and study how chemical symbols, formulas and equations are used to describe chemical reactions. Grades 7-10.
