Chem Kits –
We have a number of kits available for use by classes of about 30, with more on the way.
These are currently aimed at the middle school level. However, they can be modified for older or younger (~3rd grade). In addition, they can be used as the basis of lecture/demo by a faculty member.
Qualitative introduction to water pollution kit – Hands on experience testing for ammonia, pH, Chlorine, Chromium, Copper, Cyanide, Iron, Nitrate, Phosphate, Silica and Sulfide. We have water samples from various area creeks and streams for testing or you supply your own.
Determining Threshold Limits – Hands on experience to test the limit of detectability of a salt solution. Learn about threshold, qualitative analysis and quantitative analysis. A simulated animal toxicity test will reveal effects of toxic substances and distinguish between acute and chronic toxicity.
Chemicals in Food (Additives) – Students will investigate natural and synthetics methods to slow the rate of apple browning in sliced apples. These additives are recognized at means used to improve apple appearance and the minimal concentration to be effective will be determined.
Investigating Groundwater: The Fruitvale Story – Students investigate an area in which test well have indicated the presence of a pesticide in groundwater. They learn about groundwater movement and concentrations to the ppm level. They attempt to find the source of the contamination and suggest remedies.
Chemical Survey and Solutions and Pollution – Chemical survey introduces students to chemicals and societal issues. They explore knowledge and attitudes and report on them. Solutions and Pollution introduces properties of water and issue of water pollution. They are introduced to solutions, concentrations, acids, bases and indicators as well as dilution and neutralization as answers to pollution.
Plastics in our lives – Students investigate polymers and plastics in light of use and disposal. They will compare paper and plastic bags as well as properties and synthesis of plastics.
