The 2 point seat belt in the last picture had issues with what?

Peoples chest not being restrained and as a result their heads hitting whatever was in front of them.

Peoples hips were breaking due to the force on their waist.

The clip was coming undone, allowing people to be propelled through the window.

People slid under the seat belt, damaging knees and backs.

If I bought the first mass produced car in 1918 (the Ford Model T), one of my biggest issues would be.

In a crash, the glass would break like regular glass and severely injure of kill the passengers.

The gears went straight from first to third gear.

The seats did not come in red leather.

Air bags can cause issues with

Thrill seekers sitting on them being propelled forward.

You should never have children in the front seats of cars because?

They are sitting to low in the seat and as a result the air bag can hit them at the wrong angle, severely injuring or killing them.

They can slip down through the seat belts and break their legs.

They can fiddle with the dials on your radio, changing it to Gold FM (Which is awesome).

It's easier to ignore a child in the back seat.

The three parts of the combustion triangle include.

Hydrogen, Carbon dioxide, Water

I am cooking when an oil fire starts in a pan, the best course of action is to?

Get a fire blanket or wet tea towel and smother the fire removing the oxygen.

Tip it down the sink, hoping that the fire goes out.

Pour water on it, removing the heat.

Let it burn, eventually removing the fuel.

If someone catches fire, the best way to put them out is to.

Get them to lay on the ground and roll them over removing the oxygen from around the fire.

Find some water and tip it on them.

Take off their clothes, removing fuel.

What was one of the first safety features implemented by car companies

Earth's Water Water Everywhere. Water fills oceans, lakes, and ponds. It flows in rivers, streams, and underground. It is even in the air. Some parts of Earth have snow and ice, which are frozen water. Water covers most of Earth's surface. Salt water in the oceans makes up much of Earth's water. Earth has much less fresh water. Many plants and animals need this fresh water to survive. Some of this fresh water is aboveground, while other fresh water is underneath Earth's surface. What are some ways you use Earth's water? Different Forms of Water. Liquid water is the most common state of Earth's water. It takes the shape of the container it is in. Liquid water is always moving even if you can't see it move. It flows in rivers and streams, and it crashes as ocean waves. Not all water is liquid. When liquid water gets very cold, it freezes to form ice. Ice is another state of water-solid water. Ice can float on liquid water. People form ice into different shapes. Artists even carve ice to make sculptures. Much of Earth's frozen water is at the North and South Poles, Earth's coldest areas. Some of Earth's water is in an invisible state as a gas called water vapor. While it's always invisible, water vapor is all around us. Changing Water. Earth's water is always changing from one state to another. When frozen water is heated, it melts and becomes liquid water. When liquid water is cooled, it freezes and becomes ice. Liquid water can become a gas, too. Have you ever seen a puddle of water dry up on a hot day? Energy from the Sun changed the liquid to a gas in a process called evaporation. Water evaporates from oceans, rivers, lakes, and puddles all over the world. When water vapor in the air cools down, it changes from a gas to a liquid. This process is called condensation. Clouds are made up of tiny drops of water formed by condensation. The tiny drops stick together, creating larger, heavier drops. Once they're large enough, they fall to the ground as rain or another type of precipitation. Water Is Important. Rain keeps plants alive and allows them to keep growing. People and other animals need water to survive. We also use it for other purposes, such as fighting fires. It is important to take care of Earth's water. Keeping waste and trash away from water keeps it from becoming dirty and unusable. Polluted water makes people, plants, and animals sick. Would you want to drink and play in polluted water?

What Is a Tornado? The sky is dark far away. Something moves down from the clouds. It spins across the land. It sounds like a very loud train. A tornado is coming! A tornado is a spinning cloud. It is shaped like a funnel. Its winds can reach 300 miles per hour. That is faster than a race car. The spinning air pulls things up. It can toss a car in the air. It can even destroy, or ruin a house. A tornado can be dangerous. It can cause harm to people and places. How Does a Tornado Form? A tornado is a kind of weather. Weather is the condition of the air. Most tornadoes begin as a kind of weather called a thunderstorm. Thunderstorms are harsh rainstorms with thunder and lightning. These rough storms have high winds and heavy rain. When high winds spin and touch the ground, a tornado is born. Most tornadoes do not stay on the ground for long. When they do, they can cause a lot of damage, or harm. A tornado is a big event! Where Do Most Tornadoes Happen? More tornadoes happen in the United States than anywhere in the world. Most of them form in the middle part of our country. Scientists think this might be because warm, wet air from the Gulf of Mexico crashes with the cool, dry air from Canada. This area is known as Tornado Alley. How do Tornadoes Affect People? Tornadoes affect people and towns in many ways. Weak tornadoes break branches from trees or damage signs. Strong tornadoes can destroy buildings. People who live in areas where there are many tornadoes always think about the weather. They listen to the radio and watch news reports on television. Schools provide tornado drills so children can practice being safe in the event of a tornado. Teams of people work together to repair the damage caused by a tornado. How Can You Stay Safe? There are ways to prevent, or stop harm during a tornado. News reports use the words tornado warning to give notice that a tornado has been seen. Following safety rules can help everyone stay safe during a tornado!

Lesson 2: Plate Tectonics There are a few handfuls of major plates and dozens of smaller, or minor, plates. Six of the majors are named for the continents embedded within them, such as the North American, African, and Antarctic plates. Though smaller in size, the minors are no less important when it comes to shaping the Earth. The tiny Juan de Fuca plate is largely responsible for the volcanoes that dot the Pacific Northwest of the United States. The plates make up Earth's outer shell, called the lithosphere. (This includes the crust and uppermost part of the mantle.) Churning currents in the molten rocks below propel them along like a jumble of conveyor belts in disrepair. Most geologic activity stems from the interplay where the plates meet or divide. The movement of the plates creates three types of tectonic boundaries: convergent, where plates move into one another; divergent, where plates move apart; and transform, where plates move sideways in relation to each other. They move at a rate of one to two inches (three to five centimeters) per year. Convergent BoundariesWhere plates serving landmasses collide, the crust crumples and buckles into mountain ranges. India and Asia crashed about 55 million years ago, slowly giving rise to the Himalaya, the highest mountain system on Earth. As the mash-up continues, the mountains get higher. Mount Everest, the highest point on Earth, may be a tiny bit taller tomorrow than it is today. These convergent boundaries also occur where a plate of ocean dives, in a process called subduction, under a landmass. As the overlying plate lifts up, it also forms mountain ranges. In addition, the diving plate melts and is often spewed out in volcanic eruptions such as those that formed some of the mountains in the Andes of South America. At ocean-ocean convergences, one plate usually dives beneath the other, forming deep trenches like the Mariana Trench in the North Pacific Ocean, the deepest point on Earth. These types of collisions can also lead to underwater volcanoes that eventually build up into island arcs like Japan. Divergent Boundaries At divergent boundaries in the oceans, magma from deep in the Earth's mantle rises toward the surface and pushes apart two or more plates. Mountains and volcanoes rise along the seam. The process renews the ocean floor and widens the giant basins. A single mid-ocean ridge system connects the world's oceans, making the ridge the longest mountain range in the world. On land, giant troughs such as the Great Rift Valley in Africa form where plates are tugged apart. If the plates there continue to diverge, millions of years from now eastern Africa will split from the continent to form a new landmass. A mid-ocean ridge would then mark the boundary between the plates. Transform Boundaries The San Andreas Fault in California is an example of a transform boundary, where two plates grind past each other along what are called strike-slip faults. These boundaries don't produce spectacular features like mountains or oceans, but the halting motion often triggers large earthquakes, such as the 1906 one that devastated San Francisco.
