Hybrid cars are cars that run on both petrol and electricity. They have a small standard petrol engine and a battery and electric motor to provide electric power.

There are some differences between different models of hybrid cars, but the general principle is that the car runs on petrol, and the electric motor kicks in when additional power is required, for example when going uphill or speeding up. In some hybrid cars the petrol engine turns itself off when not needed, for example when the car has stopped at traffic lights, keeping only the electric engine running.

Traditional cars have large engines to cope with driving uphill and speeding up.Most of the time, this high engine capacity is not needed, but the engine continues burning up fuel. Hybrid cars have much smaller petrol engines, powered by electric motors when needed, so they use less petrol.

Hybrid cars are also lighter and aerodynamically(空气动力学的)designed for greater fuel efficiency.

Another way that fuel consumption is cut is by a system of“regenerative braking”(刹车). The electric motor is used to slow down the car, rather than traditional brakes. The energy produced by the slowing car is transformed into electrical power, which is automatically stored in the battery. In effect, the battery recharges when you brake. In traditional cars the energy produced when braking is wasted.

Car producers and engineers have been experimenting with electric and hybrid cars since the late 19th century. In 1928 Ferdinand Porsche built an experimental hybrid car that used both an internal burning engine and electric motors.The first mass-produced hybrid car, the Toyota Prius, came out in Japan at the end of 1997.However, Hybrid cars became available in the USA only in 1999, when the Honda Insight went on sale.

As they use less fuel, hybrid cars are cheaper to run. There are also many advantages in place to encourage people to buy them. In some countries, hybrid car owners pay a lower rate of tax, and don’t have to pay on certain toll roads(收费公路). In some cities around the world, hybrid cars are allowed to park for free.

Historical heritage is human beings’ wisdom. Historical relics, however, as time goes by, suffer different degrees of damage. People used to protect cultural relics by manual work-photographing and rubbing (拓印) techniques. Although this method can keep the basic information, many vital details are still ignored.

At present, 3D digitalization has been proved to be the most popular technology in the field of cultural heritage. The 3D digital technology can be used for data archiving (存档), displaying as well as restoration.

3D scanning (扫描) technology features fast measurement speed and accurate capturing (绘制) capacity. It’s good at collecting enough and accurate 3D data from different perspectives, which is beneficial to the restoration of historical relics when they suffer accidental damage. Experts can also virtually restore the heritage through the computer, and finish assistant research by means of accurate 3D models.

For historical relics’ protection, nevertheless, 3D scanning isn’t the only way put into use. 3D printing also contributes to displaying historical relics. It provides people with more chances to get to know historical relics and better understand human beings’ history.

Yucheng Museum unearthed a new collection of cultural relics in April 2019. One of the most urgent issues for archaeologists was data archiving. Invited by Quimbaya Art x Tech, ScanTech conducted 3D scanning immediately on these relics by 3D scanner. This handheld 3D laser scanner was equipped with the world’s leading-edge technologies and brought great convenience for further restoration and research.

To avoid any damage, Yucheng Museum combined with 3D printing technology based on 3D data to reproduce 1:1 3D models of cultural relics for exhibition, which aimed to make more people get close to history and pass on the precious historical heritage.

Many thousand-year cultural treasures have gradually disappeared from our sight due to technical problems. However, 3D scanning and 3D printing technologies provide very effective 3D solutions for historical relic display and protection.

A field trip to Pacific Science Center is a time-honored tradition for students of all ages across Washington state. Our hands-on exhibits, shows, and innovative programs ignite students’ curiosity for science in a day of exploration to enhance your curriculum and spark a lifelong interest in science, math, engineering, and technology.

In addition to General Admission, PacSci offers extra experiences to enhance your learning and support your curriculum, including:

Documentary IMAX Movies: During the school year, we offer Teacher’s Choice where teachers can book one of two open documentary slots, if your school is the first to book. Email our School Groups team for a complete list of documentaries.

Daytime Laser Show: Be dazzled by a Daytime Laser Show in our Laser Dome. Packed with 10,000 watts of concert sound, experience a one-of-a-kind show on one of the largest geocentric domes dedicated to lasers!

Planetarium Show: Enjoy a live, immersive presentation in the Willard Smith Planetarium. Blast off to the universe’s outer reaches or explore the planets in our solar system. There is always something different to experience! Seating is limited to 36 students and four chaperones（监护人）.

Below is a pricing table for our field trip.
