Forms Matter!

Grades K-1
Science, Language Arts


Starting with the Hawai’i Volcanoes National Park quarter, the students will visit the park’s website to learn about volcanoes.  The class will discuss the parts of a volcanic explosion, read a text, and discuss the three forms of matter (solid, liquid, and gas).  The students will view a volcano video and identify the three forms of matter found in the eruption.  Using the “Form Matters!” worksheets, the students will create a volcano and label the forms of matter.  The class will make gelatin, identifying the forms of matter involved.
