Lesson Plan : Types of Rocks

Teacher Name:
 Mrs. Winters
 Grade 4

 Types of Rocks
 rock, igneous rock, Sediimentary rock, metamorphic rock, weathering, and erosion
 TLW differentiate among different kinds of rocks. TLW describe the relationship between rocks and minerals.
 Goal 2: The learner will conduct investigations and use appropriate technology to build an understanding of the composition and uses of rocks and minerals. 2.06 Classify rocks and minerals
 Harcourt Science Textbook, 5 labled rock samples, trays, hand lens, science journal
 Allow the students to use the hand lens to observe the 5 rock samples in the tray at their table. Ask questions about how the rocks are alike and how they are different.
 Explain to students that today they will be reading about 3 types of rocks: igneous, sedimentary, and metamorphic. A rock is material made up of one or more minerals. Igneous rocks are formed when melted rock hardens. Sedimentary rocks are formed from sediment at the bottom of streams, lakes, and rivers. Over time the layers of sediment are squeezed and stuck together. Metamorphic rocks are formed when heat and pressure changes other types of rocks.
 Allow students to organize the concepts learned in the lesson by completing the graphic organizer on rocks as you model it the elmo.
 Students will work in co-operative groups to classify the rock samples.
Checking For Understanding:
 Students will complete a graphic organizer on rocks and glue them into their science journals.
 Review the concepts in today's lesson by asking the following questions: What are rocks? How are rocks classified? Ask different students to summarize the formation process of igneous, sedimentary, and metamorphic rocks.
 The teacher will collect the journals and check the graphic organizers for correctness.
