Step 1: What Is an Earthquake?
An earthquake is a shaking of the ground caused by the sudden breaking and movement of large sections (tectonic plates) of the earth's rocky outermost crust. The edges of the tectonic plates are marked by faults (or fractures). Most earthquakes occur along the fault lines when the plates slide past each other or collide against each other
Step 2: What Do We Have to Do at That Moment?
During an Earthquake
-If you're indoors, stay there. Get under -- and hold onto --a desk or table, or stand against an interior wall. Stay clear of exterior walls, glass, heavy furniture, fireplaces and appliances. The kitchen is a particularly dangerous spot. If you’re in an office building, stay away from windows and outside walls and do not use the elevator.
-If you're outside, get into the open. Stay clear of buildings, power lines or anything else that could fall on you.
-If you're driving, move the car out of traffic and stop. Avoid parking under or on bridges or overpasses. Try to get clear of trees, light posts, signs and power lines. When you resume driving, watch out for road hazards.
-If you're in a mountainous area, beware of the potential for landslides. Likewise, if you're near the ocean, be aware that tsunamis are associated with large earthquakes. Get to high ground.
-If you’re in a crowded public place, avoid panicking and do not rush for the exit. Stay low and cover your head and neck with your hands and arms.
After an Earthquake
-Check for fire or fire hazards. If you smell gas, shut off the main gas valve. If there's evidence of damage to electrical wiring, shut off the power at the control box.
-If the phone is working, only use it in case of emergency. Likewise, avoid driving if possible to keep the streets clear for emergency vehicles.
-Be aware that items may fall out of cupboards or closets when the door is opened, and also that chimneys can be weakened and fall with a touch. Check for cracks and damage to the roof and foundation of your home.
-Listen to the radio for important information and instructions. Remember that aftershocks, sometimes large enough to cause damage in their own right, generally follow large quakes.
-If you leave home, leave a message telling friends and family your location.
Step 3: Our Project
Our topic are earthquakes.
We choose it because There are earthquakes very often and a lot of people don't know how to protect themselfs.
We made a earthquakes simulator that shakes the ground and destroys everything.
Step 4: How We Did It?
1.We cut a piece of cardboard 2 feet tall and 1 foot wide, and then we wrap it in green velvet paper that simulate grass.
2. We painted some holllllluses and little people.
3. We cut a piece of wood 2 feet tall and 1 foot wide, we put together the two pieces with rubbers; to a base created with PVC tubes.
4. Under the base we put three flowerpots upside down with a motor attached to the top.
5. We build a mini city with houses, tractors and mountains.
6. The city was placed over the wooden base and PVC tubes.
7. Inside the PVC we put a cable that is hooked to a button and a battery.
Step 5: 1, 2, 3
That's our model.
