Third graders have been busy exploring Earth science for the past few weeks, studying different types of rocks and their properties. They learned about the rock cycle and classified different rocks as igneous, metamorphic, and sedimentary by identifying their distinguishing characteristics.
Students are also currently exploring the dynamics of planet Earth. They are learning about Earth’s structure, volcanoes, tectonic plates, and earthquakes. They also discussed the recent volcanic eruptions and learned about the two different types of volcanoes - shield and composite - as they explored the landscapes of Hawaii and Japan. Students concluded that Hawaii mainly has shield volcanoes and Japan has composite volcanoes.
Finally, third graders discussed the need to build stable structures in earthquake-prone areas. They brainstormed this idea before engaging in a STEM challenge to build a stable structure using clothespins and popsicle sticks.
