Leo grinned. “Best field trip we never left the classroom for.”
“It’s not working,” he grumbled.
Leo rubbed the balloon furiously against his hoodie, then pressed it to the wall. It stuck. “Science win,” he said. mcgraw hill ryerson science 9 pdf
They reported the loose wire to their teacher, who thanked them and fixed the circuit before anyone got shocked. Kaitlyn smiled—a real one.
Maya grabbed the textbook and flipped to the electricity unit. “Electromagnetism,” she murmured. “An electric current creates a magnetic field. If the compass is moving without a magnet, there’s stray current somewhere.” Leo grinned
Maya flipped through her worn copy of McGraw Hill Ryerson Science 9 , searching for the section on static electricity. Outside the classroom window, rain streaked the glass. Inside, her lab partner, Leo, was trying to stick a balloon to the wall.
Maya read aloud: “ Current in a wire creates a circular magnetic field. The direction of the compass needle will change if the current is alternating or unsteady. ” It stuck
If you’d like, here’s a short, original story instead, inspired by a Grade 9 science class using that very textbook:
Leo pointed at the frayed wire near the power supply. “That’s not supposed to spark like that.”
