What our Igneous Rocks lesson plan includes
Lesson objectives and overview: Igneous Rocks teaches students the traits and properties of this group of rocks. Students will discover many of the different rock types that fall into the igneous category. They will be able to identify types of rocks based on their traits and properties. They will also be able to explain how igneous rocks form during the rock cycle.
This lesson contains five pages of content. The first page reminds students what the three main types of rocks are and that they all have different traits and properties. The lesson then explains where the igneous class of rocks come into play. These rocks have two categories of their own: extrusive and intrusive. Students will learn a little about each of these groups and related vocabulary.
The lesson then outlines a number of specific rock types that belong to those two categories. Some of the rocks students will learn about include granite, basalt, obsidian, and pumice. The lesson describes several traits for each one and explains what people tend to use these rocks for. For instance, people use granite quite often for countertops, floor tiles, and paving stones. And road workers often use basalt as filler stone or road base.
For the activity worksheet, students will create an acrostic using the letters in “igneous rocks.” They must write either words or sentences that start with each letter. Whatever they choose needs to relate to the igneous category of rocks. After they create a rough draft on the worksheet, they can transfer a final draft onto a poster board. In addition, they should color and images, either that they draw or find from other resources.
The practice worksheet will test students’ memory about the traits of specific rock types. There is a total of 20 statements or traits. Students will match the terms in the word bank to the statements. There are only nine types of rock in the word bank, so the words will be used more than one time.
There are two sections on the homework assignment. For the first part, students must match definitions to the correct term. There are 10 total terms and definitions. For the second part, they will answer a series of 10 questions based on their knowledge of the lesson material.
