Forces are at work all around us. Our resource makes this invisible world easy to "see" and understand. Start by identifying what a force is before looking at different kinds of forces. Conduct several experiments on the force of friction and air resistance. Learn about net force and how more than one force acts on an object. Understand that acceleration and deceleration are examples of unbalanced forces. Explore how the force and mass of an arrow will affect its motion during flight. Explain how the force of gravity affects the weight of an object. Finally, take a look at magnetic and electrostatic forces as examples of forces that act without touching. Aligned to the Next Generation State Standards and written to Bloom's Taxonomy and STEAM initiatives, additional hands-on experiments, crossword, word search, comprehension quiz and answer key are also included.
