Science lab Building a Seismograph!!!

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:

In our first try making the Seismograph we had a problem with the pen hitting the paper and how the pen wrote. So we had to try writing with a lot of different types of pens. When the pen didn't write good we would pull the paper slower or we would tighten the rubber bands to make the pen wiggle more. When we were building the Seismograph we didn't have a lot of problems but we did have one, it was how will we hold the rubber bands and we made the Seismograph in one try which is parity good for our first time making one. It is important that scientist have Seismographs so that they can tell people and know them selfs when a earthquake is coming and how how strong it is.   

Communicate:

Hello people of the world, i would like to present a new Seismograph for scientist and for people in science class. This is a state of the art Seismograph, it will last up to 30 year and it will give you the most accurate recordings and the pen that is attached to the Seismograph is a pen that will last for over 60 years.

  1. Rafa,
    What happened to the pictures that you took? Please update your post and include. I thought your design was very inventive and the modifications worked well to get a good seismogram. Remember, data analysis and conclusion and further inquiry need to be separate from each other in a lab report. Please edit and complete each of the three sections correctly.
