Science Max: Earthquakes and Static Electricity

The video explores the science of earthquakes and how to build structures that can withstand them. It includes experiments with shaker tables and soil liquefaction to simulate earthquake effects. The video also delves into static electricity, demonstrating its principles with a Van de Graaff generator and a Tesla coil, showing how these concepts relate to lightning.

What causes the ground to shake during an earthquake?

• Heavy rainfall

• Strong winds

• Volcanic eruptions

• Two plates on the Earth's surface rubbing together

What is the purpose of a shaker table in earthquake experiments?

• To create sound waves

• To test the weight of materials

• To measure the height of buildings

• To simulate the shaking of an earthquake

What happens to soil during liquefaction?

• It changes color

• It turns into a liquid

• It becomes more solid

• It evaporates

Why did the first building design collapse during the shaking test?

• It was too tall

• It lacked a strong structure

• It was made of weak materials

• It was too heavy

What shape was found to be more stable for earthquake-resistant buildings?

• Rectangle

• Triangle

• Square

• Circle

What happens when you rub a balloon on your head?

• It becomes negatively charged

• It loses its charge

• It becomes positively charged

• It changes color

What is the function of a Van de Graaff generator?

• To produce light

• To create sound waves

• To generate static electricity

• To measure temperature

What is a Tesla coil used for in the experiments?

• To create lightning

• To generate sound

• To produce heat

• To measure pressure

How does a Tesla coil create lightning?

• By using magnets

• By using water

• By using sound waves

• By using a high voltage difference

What is the main principle behind the experiments with static electricity?
