This activity illustrates some of the uses of limestone and limestone products by relating them to everyday activities of the students. Students fill in a timetable of their activities in the morning from waking up to leaving for school. Discussion with the teacher and/or reference book or web-based research follows, and students will discover that a number of activities have a link to limestone in ... Full description.

This site contains generic instructions for conducting water quality testing. Several different tests are described that can be conducted over short or long periods of time. The site explains how to gather and treat the data and has suggested questions for the students to see if they can properly analyze the data. The objectives are to familiarize students with real-world gathering of scientific data ... Full description.

This video lecture explores the chemistry of the hordes of molecules in the interstellar medium revealed by radioastronomical observations of our galaxy. Extremely fast reactions result in the high abundance of complex organic compounds in the space between the stars. The chemistry of the interstellar medium illustrates that complex synthesis occurs under totally abiotic conditions. The specific reactions ... Full description.

In this activity, students will investigate the weathering of rocks by chemical processes. They will use effervescent cleansing tablets as a model for rock, and vary surface area, temperature, and acidity to see how rapidly the "rock" dissolves. This investigation will help them understand three of the factors that affect the rate of chemical weathering and develop better understanding of how to design ... Full description.

Students investigate variables that may influence the growth of crystals which they have learned to make. There are two options for implementing this activity. The first is open-ended, with the students deciding what variables affect crystal growth and then deciding on the manipulating variables they would like to study. The second is prescriptive and explains to students how to test three variables ... Full description.

This activity introduces students to the concept of the chemical formation of a mineral from a hot, semi-liquid melt, and to basic stoichiometric concepts regarding the formula of a mineral (or chemical compound). It can be performed by the students themselves or as a demonstration by the teacher. They will weigh out samples of iron filings and of sulfur, test them, make some observations of their ...

This demonstration reinforces the concept that minerals can form even at low temperatures, meaning that these processes can occur at or near Earth's surface. Using 'water glass' (sodium silicate nanahydrate) and any of a variety of metal salts, the teacher can grow crystals of silicate at room temperature in a container as the students watch and record their observations. A student worksheet and discussion ... Full description.

This activity introduces students to the idea that crystals 'grow' (crystallize or precipitate) and that minerals or rocks also form this way, providing a very general idea of the nature of magma (molten material that eventually crystallizes into igneous rocks). Using solutions mixed by the teacher, they will observe and sketch the formation of crystals of potassium dichromate and copper II acetate ... Full description.

In this activity, students will be introduced to the concept of mineral stoichiometrics (ratios of atoms in a compound) by performing a chemical reaction between copper and sulfur, which can result in either covellite (CuS) or chalcocite (Cu2S). Working in small groups, they will heat measured amounts of copper and sulfur in a crucible until constant weight is achieved, then calculate the theoretical ... Full description.

Comment on this resource
Methyl tertiary-butyl ether (MTBE), a fuel additive, is highly mobile in groundwater, dissolving and traveling faster than the other petroleum constituents which tend to biodegrade and adsorb to soil particles. This unit will introduce the problem of pollutants as they move through the various soil layers and contaminate the groundwater and challenge the students to investigate the effects of MTBE ...
