A full answer key backs every parachute, lever and pulley activity in this workbook, trimming a teacher's marking time. "Label the Skidding Car" and "Match the Surfaces" build friction vocabulary before "Friction Variables" turns the concept into a real investigation. "Fish or Rock?" and "Gravity Variables" test water resistance and gravity side by side, and a closing "Machines: Who Is Right?" cartoon checks understanding of simple machines. Three reflection activities run through the book, with a word bank at the back. NGSS codes 3-PS2-1 and 5-PS2-1 are covered.

Inside:

• "Label the Skidding Car" and "Match the Surfaces"
