Curling Momentum Lab This lab is designed to have students investigate the nature of a nonlinear collision using curling stones. Students will be able to look at how the velocities before the collision and the mass of the stones affects the results of the collisions. YouTube video describing the lab Possible student directions Energy Loss on Bounce Guided Lab This guided lab is designed to have students investigate the amount of energy lost by a ball when it bounces. This guided activity is meant to be used as a pre-lab for students who will do this lab live.

To meet this mandate, EPA's research program is providing data and technical support for solving environmental problems today and building a science knowledge base necessary to manage our ecological resources wisely, understand how pollutants affect our health, and prevent or reduce environmental risks in the future.

The National Risk Management Research Laboratory NRMRL is the Agency's center for investigation of technologi- cal and management approaches for preventing and reducing risks from pollution that threatens human health and the environment. The focus of the Laboratory's research program is on methods and their cost-effectiveness for prevention and control of pollution to air, land, water, and subsurface resources; protection of water quality in public water systems; remediation of contaminated sites, sediments and ground water; prevention and control of indoor air pollution; and resto- ration of ecosystems.

NRMRL collaborates with both public and private sector partners to foster technologies that reduce the cost of compliance and to anticipate emerging problems. NRMRL's research provides solutions to environmental problems by: Monitored Natural Attenuation is widely used by U.

EPA to manage risk associated with hazardous organic contami- nants in soils and ground water. The Agency prefers attenuation mechanisms that destroy contaminants. As a result, site characterization at hazardous waste sites has focused on biological degradation of organic contaminants because biodegradation was the only mechanism that was widely acknowledged to destroy organic contaminants.

In recent years it has become increasingly apparent that abiotic degradation mechanisms can make a substantial contribution to natural attenuation of a variety of halogenated organic compounds in soil, sediment and ground water. This report provides a technical basis to evaluate the contribution of abiotic processes to MNA of halogenated organic compounds.

The report reviews the current knowledge of the rate of transformation of halogenated organic compounds that is associated with reactive mineral phases in soil and aquifer sediment.

The report also reviews the known trans- formation products. Paul, Minnesota B. Ternary diagram showing the importance of controlling factors on iron sulfide formation in natural aquifers and biowalls 5 Figure 1. The data series Not freeze dried [2] and Freeze dried [2] repeat data from Figure 2.

The College Board-AP Physics 1/2/C originated in the USA, the Cambridge Physics A/AS-levels generated in the UK, and the IB Diploma Programme Physics SL/HL created in Switzerland are different schools of thought about teaching Physics at the high school level to years old students.

The desire to have available a suitable “material to measure” for every conceivable purpose has left its m ark on their development. Natural and, predom inantly nowadays, synthetic polymers, fulfil this requirem ent virtually ideally.4/4(8).
