The Rock Cycle . How Rocks Change Introduction Does it seem to you that rocks never change? For example, if you find a chunk of granite today, can you expect that it will still be granite at the end of your lifetime? That may well be true — but only because our lifetimes are very short relative to the history of the earth. If we take a step back to look at geologic time (which focuses on changes taking place over millions of years), we find that rocks actually do change! The way rocks change depends on various processes that are always taking place on and under the earth's surface. Heat & Pressure What happens to cookie dough when you put it in the oven? A similar process happens to rocks beneath the earth's surface. An additional factor that can transform rocks is the pressure caused by tons of other rocks pressing down on it from above; heat and pressure usually work together to alter the rocks under the earth's surface.

Activity 3: Igneous Rocks - Bryce Canyon National Park Chemical CompositionChemical composition of igneous rock can often be estimated just from looking at the rock. Geologists look at the proportions of light-colored and dark-colored minerals in an igneous rock to estimate the chemical makeup of rock. Light-colored or felsic, minerals have more silica in them. The mineral proportions of the rock are what allows geologists to classify rocks chemically. Felsic rocks are high in silica (65% +). Instructional Procedures: Create colored tags for the students to wear. Discussion: What type of igneous rocks were formed? Extension: For teachers interested in rock identification, the following is a suggestion of how you can set up a rock-ID activity. For pictures of common rock-forming minerals, refer to .
Schools Outreach Program @ Warwick Chemistry - University of Warwick What is Outreach? Warwick Chemistry has an active outreach programme for both primary and secondary schools. Coordinated by our enthusiastic outreach officer Nick Barker, our academic staff, researchers and PhD students get involved in chemistry-based scientific activities with around 7000 young people each year. We invite groups of school students to our Department for days in the teaching laboratories, tours, tutorials and workshops and we are happy to visit schools to give lectures about some of the research going on here or to teach the fundamentals of the subject to younger students as part of a practical demonstration lecture. Laboratory visits are fully booked until September 2014 What age groups do we work with? We work with school students aged from six to eighteen years old. For Key Stage 2 pupils, we can provide a demonstration lecture (containing some quite loud bangs and flames!) Work Experience (fully booked for academic year 2013 - 14) How much does it cost?
Great Plant Escape - All About Seeds Seeds come in different sizes, shapes, and colors. Some can be eaten and some can't. Some seeds germinate easily while others need certain conditions to be met before they will germinate. Do you know that within every seed lives a tiny plant or embryo? You can hold in your hand 500 radishes, many thousands of petunias, or an entire meadow if you remember that each seed is a plant! Seeds travel! Next, learn about the parts of a seed >>>
