Which is an example of practicing good laboratory safety?, Wearing safety goggles when instructed, Throwing materials into the trash, Touching hot materials, Running while carrying glassware, Which force pulls objects toward Earth?, Magnetism, Friction, Gravity, Light, A student slides a book across a table. The book eventually stops. Which force is mainly responsible?, Gravity, Friction, Magnetism, Light, Which is an example of magnetism acting at a distance?, A magnet attracting a paper clip without touching it, A hand pushing a box, A shoe rubbing against the floor, A ball falling to the ground, Which surface would have the greatest amount of friction?, Smooth ice, Polished glass, Rough sandpaper, Smooth plastic, Two magnets are placed with their north poles facing each other. What will happen?, They will attract, They will repel, They will melt, Nothing will happen, A student wants to investigate which surface creates the most friction. Which investigation would be most useful?, Slide the same object across different surfaces and compare how far it travels., Drop different objects from different heights., Put different magnets together., Measure the temperature of different objects., A ball is thrown into the air. What force causes the ball to eventually return toward the ground?, Friction, Magnetism, Gravity, Sound, What is the mass of the toy car?, 20 g, 22 g, 121 g, 21 g, Which of the following will be attracted to a magnet?, Styrofoam cup, Iron key, Copper Penny, Plastic toy, Which object can be classified as more dense than water?, Metal Nail, Wooden Twig, If an item is less dense than water, it will ________, Sink, Float, Which substances did the student most likely use to make a solution?, Marbles and Salt, Salt and Water, Marbles and Water, Marbles and Sugar, Which substances did the student most likely use to make a mixture that is NOT a solution?, Water and Salt, Sugar and Water, Water and Honey, Marbles and Water, A student tosses a beanbag into the air. How does gravity affect the motion of the beanbag?, Gravity allows the beanbag to continue moving upwards., Gravity pushes the beanbag towards the Earth., Gravity pulls the beanbag towards the magnet, Gravity causes the beanbag to stop moving upwards and pulls it down to the ground., A soccer player kicks a ball, causing it to move across the grass. What is causing the ball to change its motion?, Sound, Temperature, A force, Light, A student rolls the same toy car across three different surfaces. The car travels the shortest distance on carpet. What does this most likely show?, Carpet produces more friction than the other surfaces., Carpet produces less friction than the other surfaces., Gravity does not act on the car, Magnetism makes the car stop., Which of the following is a contact force?, Gravity pulling you down to Earth, Magnet attracting an object, Wind blowing leaves off of a tree, Pushing in your chair, Which of the following is a non-contact force?, Wind blowing leaves off of a tree, Pushing a box, Pushing in your chair, Pulling a string, Which statement best describes the difference between gravity and magnetism?, Gravity pulls objects toward Earth, while magnetism can attract or repel certain materials or magnets., Gravity only affects magnets., Magnetism always pulls objects toward Earth., Gravity can only act when objects are touching.
