![]() Students will summarize their understanding of the 3rd law of motion in their science log books & think of another evidence and/or application of the law in their everyday lives. The number of coins that are flicked into the row of coins will be the same as the number of coins that fly off. Students will repeat the process, flicking 2 coins, then 3 coins at the row of 5 coins & drawing what they observe. Students will draw a diagram of their observations. At this point there is nothing preventing the last coin from moving, so it flies off. So, the force of the impact is passed on to the next coin until it gets to the end of the line. However, by allowing students to participate in inquiry-based lessons and activities. These laws of motion can be difficult for children to understand. In 1666, Sir Isaac Newton stated the three laws of motion. But it can't move because it is prevented from doing so by the next coin in the line. Science Project on Gravity and Motion for Third Graders. When you flick the coin, it hits the first one (the action) and that coin then tries to move away from the first one (the reaction). This phenomenon is explained by Newton's Third Law of motion which states that to every action there must be a reaction. Students will repeat the activity several times. The whole group of coins will move a little, but the end coin will fly off. ![]() They will place a 6th penny on the other end between the rulers & flick it at the 5 coins. Secure the rulers to the table with tape. Students arrange the 2 rulers on the table top with the line of 5 pennies between them, all touching & 1 inch from one end. Materials needed per student pair: 2 rulers, 6 pennies, tape, science log books
