Creativity!1! ANYONE here got creative ideas please help!?

Question

i need ideas for a simple machine, but I cant think of anything creative, or functional that I can really build? Any Ideas/suggestions? Also i cant build things like nut crackers because my freind already did that.

Answer 1

Here are a bunch of projects that demonstrate simple machines:

Levers have 3 parts. The part where the lever is supported is called the FULCRUM. The part from the fulcrum to the weight you want to lift is called the WEIGHT ARM. The parit from the fulcrum to where you are pushing or pulling is called the FORCE ARM.
Question: Is a weight easier to move when the force arm is longer, shorter, or the same length as the wight arm?
Materials: juice can, board, books
Procedure: Make a lever using the board and juice can.
2. Put four books on one end of the lever. This will be the weight you need to lift.
3. Adjust the board on the fulcrum to make the force arm shorter than the weight arm.
4. Add books one at a time to the force arm. Record how many books it takes to move the weight arm.
5. Repeat steps 3 and 4 with a longer force arm and a force arm the same length (the fulcrum, juice can will be in the center.)
Results:
1. Is a weight easier to move with a shorter, longer, or same length force arm?
2. Is that what you thought?
3. What did you learn?

Messages on A Pulley
A PULLEY lets us change the direction of the force we use to do work.

Question: Can you use a pulley to help you send messages across the room?
Materials: 2 thread spools, 40 feet of string, 2 round pencils, paperclips, message
Procedure:
1. Put the pencils through the thread spool centers. Tie the ends of the string together to make a loop. Have one person hold the ends of one pencil (allowing the spool to turn freely. Have one person hold the other spool. Wrap the string around the spools to create a pulley system.
2. Write a message, attach it to the pulley with a paper clip. Have a third person pull the string to move the message.
Results: Did you message travel across the classroom by pulley?
2. Is that what you thought would happen?
3. What did you learn?

Roller Skates
A WHEEL and AXLE help us turn something more easily or move something across a surface more easily. That is, with a wheel and axle, you use less force.
Question: Which needs less force to be moved, a roller skate on its side or on its wheels.
Materials: 2 roller skates, 2 rubber bands the same size, yard stick
Procedure:
1. Attach rubber bands to roller skates.
2. Measure the length of the rubber bands before you pull.
3. Put the skate on its side. Measure the rubber band during the pull.
4. Pull the skate on wheels. Measure the rubber band during the pull.
Results:
1. Whic skate needed less force to be moved?
2. Is that what you thought?
3. What did you learn?

Carry My Books
An INCLINED PLANE 9or ramp) is a flat surface with one end higher than the other end. An incled plane lets us raise heavy things without having to lift tme straight up.
Question: Which is the easier way to lift 3 books-straignt up, or by using a ramp?
Materials: board, 10 books, string, spring scale

Proceudre:
1. Tie 3 books together. Stack 7 books in a pile.
2. Lift the 3 books to the top of the seven book pile with a spring scale. Record the weight.
3. Use the board and seven books to make an inclined plane.
4. Pull the 3 tied books up the ram with the spring scale. Record the weight.
Results:
1. Which was the easier way?
2. Is that what you thought?
3. What did you learn.

Nails
A WEDGE is like two incline planes (ramps) put back-to back. But, there is a difference in how they work. Something ismoved over an inclined plane, while a wedge moves through something. A wedge is used to split, cut, or go through something.

Question: What is easier to pound into a board_ a nail with a point (wedge or a blunt nail?
Materials: large nails without and without points, hammers, board, rulers
Proceudre:
1. Measure the nails and record.
2. Hammer the nail with the wedge five times. Measure the part of the nail you can see and record.
3. Hammer the nail without the wedge five times. Measure the part of the nail you can see and record.
Results:
1. Which nail was easier to pound?
2. Is that what you thought?
3. What did you learn?

Count the Turns
A SCREW is used to hold things together It has a line that goes around it that is called THREAD (actually a twisting inclined plane).
Question: What type of screw takes more turns to go into a block of wood - one with more or less thread?
Materials: Wood block, same size screws with different sized threads, screwdriver, masking tape
Procedure:
1. Wrap a screw driver handle with a piece of masking tape. Make a mark on the tape. YOU WILL COUNT ONE TURN EACH TIME THE MARK COMES BACK TO THE PLACE IT STARTED>
2. Place the screw driver into the slot of one screw. Watch where the mark is and start turning the screw to the right.
3. Count how many turns it takes to get the screw all the way into the wood.
4. Repeat for the other screw or screws.

Results:
1. Which screw took more turns to go all the way into the wood?
2. Is that what you thought would happen?
3. What did you learn?

Answer 2

I had to do that once. You can build a catapult (which is what most people did), a see-saw, or any other simple machine. If you've ever seen the board game "mouse trap" doing something like that would be great, because the trap is just a bunch of simple machines connected. You can use any search engine to find project ideas as well I suggest ask.com in the kids section. Good luck!

Answer 3

How about a Rube Goldberg type of machine? (A marble falls down into a cup, the cup tips over and knocks an egg across the floor, which hits a dominoes that hits a plastic fork, which turns on a switch, ... etc).

Answer 4

We did the identical factor for my artwork magnificence. We ended up portray a town scene. We simply painted grey constructions all bunched along side asymmetric tops and we painted like, a pink sundown colour over it. It was once relatively beautiful and effortless.

Answer 5

simple AND functional? invent something not too big that can be used in a kitchen to loosen tight jar lids... lol but i'm not joking either.

Answer 6

a doorbell is extremely easy
