What if you replace pennies with quarters? Will it take fewer or more coins to do the job? (If you tell your kids they can keep all the quarters they use to get the apple up the incline, they will be even more enthusiastic!).How changing the angle of an incline by adding a book (or taking one away) will change the number of pennies required?.Friction, force, gravity, ramp, the angle of slope, motion, distance are all involved in this simple setup. It’s hard to believe, but in this fun experiment, kids learn a lot about physics through hands-on investigation. Your answer would depend on the size and density of your apple and the steepness of your incline. So h ow many pennies did it take to get an apple up an inclined plane? In our experiment, it took 63 pennies to get our apple to move a bit and 108 to get it all the way up the ramp. At what count did the car inch up? How many pennies did it take to get it all the way up? While counting out loud, start putting pennies into the container. The accuracy of this experiment increases dramatically if you eat an apple while performing it! and hang the plastic container over the higher end of the board.set the apple down near the other end of the board.Put five books under one end of a board.Who got the closest to the right answer? Read on to find out. My 5-year old said, “175 pennies!” And I said 50. My 8-year old said that it would take 100 pennies to take our apple up the incline of 5 books. Tie a longish string connecting the plastic container and apple.You might have to experiment with a couple of different rubber bands until you find just the right fit. Put a rubber band on the apple (so you can connect it to a string).Your container should look like a little bucket with a handle. Thread a string through the holes and tie it security.Poke two holes on two opposite sites of your yogurt container or plastic cup.Hole puncher or scissors to make holes in the containers.A rubber band (it will go around an apple).An apple (maybe even a couple of apples of different size).A yogurt container or a plastic cup for pennies.It’s not messy! How many pennies does it take to get an apple up an inclined plane? What you need Since the weather is gorgeous this time of the year, we set up the experiment in our backyard, but you can do it in the living room or classroom. Today, instead of pulling an apple up the inclined plane, we are going to have pennies do the job for us. (Remember this when you study how Egyptian pyramids were built). However, when you slide something up the inclined plane, a portion of the weight is supported by the ramp. When something is lifted vertically, you support the whole weight of an object. An inclined plane helps to reduce the weight of an object. ![]() People invented them to make their lives easier. ![]() ![]() This baby is a born scientist.Īn inclined plane is just a flat object that is tilted so that one end is higher in space than the other end. She wants to know how far she can go up before gravity forces her to slide down. “ It’s the wrong way,” say parents, but I guarantee you, it’s not the wrong way as far as the baby is concerned. Take a baby to the park, and one of the first things she is going to do is start crawling up the slide. Kids are born fascinated with inclined planes. Can you get an apple up the inclined plane using pennies? How many pennies does it take to get an apple up an inclined plane? Inside: This apples and pennies science experiment is a delightful twist on the traditional inclined plane experiments.
