The Three Types of Rocks

The first thing we did together was to sing the “Rock Song.” It was to the tune of Row, Row, Row Your Boat and talked about how sedimentary, igneous and metamorphic rocks are formed. Then he put the cards in the rocks and minerals chart. He really loved that and thought the chart/cards were “cool.” Don’t miss our FREE Rocks and Minerals Packet . We also have a Free Worksheet...

Sedimentary Rock Activity 6

Sedimentary Rock Activity

For sedimentary rocks, we talked about how the rocks were formed by layers building up one a-top the other. Then we made our own sedimentary layers. We had different colors of sand (I added food dye of various colors to the sand and mixed it together the night before). We also collected dried up leaves and small pebbles to add to the layers.

Igneous Rock Activity 0

Igneous Rock Activity

In talking about igneous rocks, we looked at the cards from teacherdesk.info and talked about how some lava cools quickly (like obsideon) and some cools slowly (like granite). Melting wax from a candle was like lava cooling quickly and after the wax had cooled for a few moments we felt how smooth it was and compared that to the obsideon rocks we have from the rock kit.

Metamorphic Rock Activity 2

Metamorphic Rock Activity

We talked about what a geologist does and brought out this “land recreation.” LD and DD took turns taking “core samples” from the earth with the straw. They could tell that it was made of different layers. Metamorphic rocks are made when pressure and heat change the rocks. The oven was our ‘heat and pressure source’ for creating these “metamorphic rocks. Then we took rock samples (below) and looked not...
