Rocks Sciguide ROCKS!
The Rocks sciquide is a comprehensive guide to rocks and the study of rocks. It has a variety of activities and resources for students in grades 5-8. The sciguide has three main components: Formation of Rocks, History of Rocks and Soil. I will start my review with the Soil section as this section had the most appropriate resources for my younger students and I found quite a number of lesson plan ideas in this section. The soil section of the rocks sciguide provided some excellent discussions and insights on types of soils, compositions of soils, weathered rocks and weathering processes and the progression of soil development over time. The guide provided a very interesting lesson plan about the soil of Mars. I enjoyed the student sample which provided some good insight into what a product of the lesson plan might be. The science object that was part of the lesson plan on rocks gave me some great ideas and some solid content knowledge on the subject of soil and rocks.
Another section of the sciguide was the History of Rocks. This section provided fascinating discussions and content on the topics related to the age of rocks, how rocks are dated, what they tell us about the earth and the age of the earth and how the process of recycling of rocks occurs over time. There are some great interactive sections for students that provide excellent information in a media filled and interesting forum.
The third section was the Formation of Rocks and covers the process of the rock cycle in an interesting and fun manner. There are a number of flash simulations that make this section very interesting and engaging. All of the lessons are appropriate for an older elementary and a middle school group of students, however, I found a number of ideas that I could modify as I start my earth science unit. My students are in a compare and contrast unit and in one of the sciguide resources there was an excellent lesson plan on taking two rocks and using a Venn Diagram to compare and contrast rocks. Students get hands on experience of observations and also of looking at rocks closely to determine the different properties and characteristics they see. I found this sciguide to be very useful even if it was meant for an older age group. It certainly provided me with some excellent content knowledge.
