FC: Leprechaun Trap Projects Mounts' Class March 2011
1: Mrs. Mounts' third graders put their knowledge of simple machines and forces of motion to good use by designing and setting Leprechaun traps for St. Patrick's Day. Please enjoy their finished projects on the following pages.
2: Our simple machine is an inclined plane. We use it to let the leprechaun climb up the trap. We used a noncontact force. Our force of motion is gravity. You see, gravity keeps him on the ground. So when he walks up the inclined plane, gravity keeps him on the ground so he trips and falls. Our attractor is gold. we used a real gold coin to bait him. This is how it works. He walks in and trips on the string and faceplants on the top. Then when he tries to escape he will not be able to get out because the ledges are too high. That's how it works.!
4: This is how our trap works. He will walk in and pull the chocolate, so it will shut the door and trap him in the box. Our simple machine is a pulley. Our force is a pull which is contact force.
6: We made a giant mansion for the leprechaun. It has a pool, a diving board, and a kitchen with chocolate. It also has an inclined plane. It's a castle. It's huge. We also have beds and it's bulletproof. And a lot of people can hang out there in the swimming pool. The leprechaun is going to jump off the diving board and fall because of gravity, and that's a non contact force. It's a leprechaun thing.
8: Our leprechaun trap uses an inclined plane to catch the leprechaun. The force that the trap uses is gravity, which is a non-contact force. The parts to lure the leprechaun are: Gold, chocolates, and the color green. This is how the trap works. First the leprechaun sees the trap and a sign that says FREE GOLD.” Then he will walk into the trap and trip on the trick wire. Last the doors will close and he will get trapped in the box forever.!
10: We used the simple machine called an inclined plane, which is another name for a ramp. We used green paper, a Capri sun box, duct tape, a thin wire, and green cloth. We used lots of chocolate and gold nuggets to lure him. Then he would trip over a wire and falls on duct tape. Our force of motion is gravity because he trips over the wire and gravity pulls him down. Gravity is a noncontact force.
12: We made a trap to catch a leprechaun. The materials we used to make our trap are a box, green tissue paper, popsicle sticks, tape, chocolate, and fake gold. We used 3 inclined planes. Our non-contact force is gravity. The gold and lots of green will attract leprechauns. He will get gold on the way. First the leprechaun will climb up the inclined plane, or a ramp, and the next and the next until he reaches the top. He will drop down the tube and find chocolate inside but he will be trapped in the box. That is how you trap a leprechaun.
14: Our trap uses an inclined plane to catch the leprechaun. We use a non contact force. Our force of motion is magnetism. The items we used to attract the leprechaun are: chocolate, the color green, and gold. How our trap works is the leprechaun sees the gold (washers) so he goes inside the box. There is a trail of gold leading to a tunnel. In the tunnel is chocolate. When the tunnel ends he sees some more gold so he runs towards the gold but then he gets tripped by a trip wire. When he falls, the gold in his hand will get attracted to the magnetic tape. Then he will be stuck there with no way to escape. That is our leprechaun trap.!
16: For my leprechaun trap I have used two forces of motion. My trap has one thing to attract a leprechaun. I have also used one simple machine. My leprechaun trap used a noncontact force and a contact force. My noncontact force is magnetism. My contact force is pull. In my trap there is a pot of gold on a net. Somebody would hide behind the tree that holds the pulley system by a rope. When the leprechaun discovers the pot of gold, the person would pull the rope. Then the net would close on the leprechaun. But if the leprechaun escapes with the gold the magnet would attract the leprechaun with the gold. That's how to catch a leprechaun.
