The more students are able to test the various properties of materials, the better understanding they gain in why we use certain materials for a particular purpose. This lesson allows students to investigate and test the FLAMMABILITY of different objects! Perfect for your 2nd grade physical science unit! Students will predict, test, and use data collected to rate materials on a flexibility scale. Students will also practice the skills of justification and apply their learning to real word scenarios!
