Experiment Number 1-Highway Seismograph
Things you will need:
Step 1- Get into the front seat of your car and hold your first piece of paper against the dashboard with one hand. In the other hand hold your pen/pencil and put it on one side of the paper.
Step 2 - Now have your driver start to drive on a bumpy road. While you are driving along start to move the pen/pencil across the page.
Step 3 - This should form a jagged line across the page. What happened was every time the car hit a bump, it accelerated foward. Since your body is strapped firmly to the car with your seatbelt, you accelerate with the car.
Experiment Number 2 - Seismic Slinky
Things you will need:
Step 1 - Stand about two meters apart from your partner and have one of you pull the slinky toward yourself then quickly push it away. The slinky will move back and forth along the same direction. This type of wave is called a longitudinal wave, or compression wave. It is a model for seismic Primary waves(P-waves). They're called P-waves because they are the first to arrive at far points.
Experiment Number 3 - Seismic Slinky
Things you will need:
Step 1 - Stand about two meters apart from your partner again and have one person shake their end of the slinky up and down. There is now a different type of wave that travels across the slinky than in the previous experiment. This type of wave is called a transverse wave. A transverse wave can travel through solids, but not through a liquid or gas. The transverse wave you made with the slinky is like the seismic waves called secondary or s-waves, that travel through solid rock.
