Science Lap Buliding A Sizemograph

Hypothesis:

Can you design and build a seismograph that can record the movements of simulated earthquakes?

Prediction:

I think our seismograph will work and we will make it.

Materials:

• Cardboard box
• A couple of rubber bands
• Some safety pins
• A pen that is fine point
• Paper that has a chart system
• String 
• Tape 
• Toilet role  
• Knife

Procedure: 

1. Get all the materials that you need
2. Get the cardboard box and the knife and then cut the bottom of the box off and the one side of the box so you can see into the box.
3. Now get the knife and make one hole in two sides that are parallel and make three holes on the top of the box and make t in the shape of a triangle. 
4. Then get the string and put it through the top holes and then tape the ends of the strings to the pen and make sure the pen can touch the bottom of the box. 
5. Now get the rubber band and put one rubber band through the holes on the sides and then attach them to the pen and then on the outside of the box use the pin and put it on so that the rubber band doesn't go into the box.
6. After get the toilet role and the paper and tape one side of the paper to the role.
7. Ok now put the paper under the pan.
8. Now your almost done, now you just have to make the box shake and you have to pull the paper away from the pen.
9. And now you have waves recorded on your paper and you will know when a earthquake happens. 

Analyze and Conclude:

When we started to shake the table the pencil failed because we needed to put the cardboard on the bottom so the pencil didn't touch the paper so we had to glue and tape the card Bord on the bottom of it so the paper and the pencil are touching. We did tree tests the first test one was when we shakeup the table hard the pencil and the seismograph showed how strong is the earthquake.   

Communicate

Hello  everybody this is a new way of finding the earthquake this will develop the word it will show the exact how the earthquake occurred and how strong is it. This wasn't a big machine it is a small one it can fit in you room it is perfect for you.
