Gigo Learning Lab’s complete series includes individual packages and school sets. The special features of Gigo’s Learning Lab are as follows:
Using Gigo’s “building block” construction-based curriculum, every class has a readytoassemble model, and includes time designed to promote individual creativity. Promotes thinking outside-the-box of the traditional educational framework by learning innovation through play! We are all innately good at something, so we should take into account both individual development and the ability to work as part of a team effort.
Course levels are designed from elementary to difficult, combining a life sciencesbased curriculum with applications from daily life.

Experiment using Gigo’s “building blocks”, which can be used over and over again, saving both time and effort. We hope that kids can enthusiastically learn scientific knowledge through fun hands-on experience, developing their problem-solving abilities, as well as a positive attitude towards science. Our mission is to help children apply their newfound knowledge to daily life, furthering their innovational skills and abilities.

1 Elastic Scale ass and Weight Scientific Application DailyApplicationDaily
n earth, the mass of a kg ob ect is weighed as kgw, but on other planets, because of different gravitational in uences, the weight of a kg ob ect is not necessarily kgw. ass and weight mean different things scientifically. ass is the amount of matter in an ob ect. ou can use a balance to weigh it. o measure mass, we will place an ob ect in the pan on one side of the scale and a balancing weight on the other side. When the transverse lever reaches a hori ontal position, the mass is obtained. Weight, on the other hand, is a kind of force, the gravitational force between the specific ob ect and the arth. spring balance is usually used to measure the weight of an ob ect. Weight varies with the force of gravity at a location. lease note that weight can change with location while mass always stays the same.
igi hung the suitcase on the hook of the scale with addy s help, it weighed kg he then started to weigh all the things she could find at home.
ust when igi had finished weighing everything she could find, her dad took out a wooden ball and an iron ball which looked identical in volume. igi s ad asked her to guess which one had a greater mass, and also told igi that the mass of an ob ect could not be measured by a spring scale.

uring practice, igi found out that the skateboard does not move easily on grass, it sometimes gets stuck. igi asked curiously, what is stopping theommyskateboardtold
igi, When an ob ect moves on a surface, there will be obstacles between the two contact surfaces that create a resistance, which we call friction. riction always works in the opposite direction to the direction of movement. igi now reali ed there is more friction on the grass, and that is the reason why the skateboard gets stuck.

When an ob ect moves on a plane, there is a force that obstructs ob ect movement between two contact surfaces. his is called friction , which is always the reverse direction of the applied force or the direction of movement. or a car to run fast, for e ample, the tires must have sufficient friction in order to prevent accidents as a result of skidding. his is why it is necessary to slow down when driving in the rain. he friction of wheel bearings, on the other hand, needs to be decreased in order for the wheels to rotate smoothly and minimi e energy consumption.

lastic force refers to the recovery force generated when ob ect deformation occurs.
ach ob ect has a different deformation limit which is called the elastic limit. When the generated deformation amount is smaller than the elastic limit, the ob ect can recover its original state, or else it can t recover. he relationship between the length the spring e tends and the tension is ooke s law. When the spring e periences elastic deformation, the si e of the elastic force and the length by which the spring e tends or compresses is proportional to each other. ice are annoying, in addition to damaging the furniture they also spread terrible diseases.heteacher asked students to think of a way to solve the mouse problem in class. veryone got into teams and came up with creative ideas. ecause there were so many great ideas, the teacher asked each team to turn their ideas into real functioning devices. fter an intense discussion, igi and her team members decided to make a mousetrap. his mousetrap applied the principles of leverage and elastic. tudents in class found it very special and interesting. he teacher then e plained to the class that a mousetrap like this is too powerful. t s not only harmful to mice, but also dangerous to house pets, and is officially forbidden by the local government.

What other applications does a belt pulley have primary characteristic of a belt pulley is that two or more pulleys are inserted in one belt drive and the belt is the medium used to drive transmission of power from one pulley to the other. n factories or other things we see in daily life, belts are widely used. n addition to transmitting power, they are also used to convey goods. or e ample, the conveyer belt systems in airports. igi has got many ideas she is determined to be an inventor. igi went to a hypermarket with her om, she saw her om put all the things they wanted to buy on the checkout counter, and all the things moved forward by themselves. he took a careful look at it and found out that there was a big belt that helped to convey the goods. his is a similar idea to when the sushi train conveys food to its customers. igi looked online to figure out the secrets of the conveyer belt. conveyor belt features two or more transport rollers mounted on one belt. he power is transmitted, via the belt, from one pulley to another.

What other applications does a sprocket have Chains on bicycles are something we see often in everyday life. When you apply force to the pedal, the crane sprocket starts to rotate. his moves the chain, the chain drives the small sprocket connected with the rear wheel and this rotates the rear wheel. nce the rear wheel starts rotating, the bicycle moves forward. he power transmission between the two sprockets is the same as the pulley, only the sprocket is driven by the chain, and if the sprocket is overloaded, the chain or the sprockets teeth will break. randpa udolph has a sturdy bicycle that he rides every day to drop ogo off and pick him up from school. n his day off, randpa took ogo on his bicycle to the mountains to see the cherry blossoms. While they were en oying the beautiful views along the way, the bicycle got stuck and ogo almost fell off the bicycle. randpa said that the chain had slipped off and he needed to fi it. ogo did not know what a slipped chain was until he saw the chain lying on the ground. e worked with randpa and finally they reattached the chain to the chain wheel. hey were able to continue their cherry blossom tour on the bicycle.

Where do you see fi ed pulleys in your everyday life he pulley is one of the most common and simple machines. ecause of the notches on the circumferential surface of the pulley, it can be used on any side of the wheel. he friction between the rope and the wheel will cause the pulley to rotate around its central a is.

What other applications does a movable pulley have n ordinary pulley is a disc that turns around the central a is but the central a is of a movable pulley is mobile. When a movable pulley is used, the direction where the force is applied cannot be changed. he pulling force applied through the movable pulley towards one end of the rope, however, e uals half of the load. n other words, one can pull a heavy load less strenuously. t is an important trait of a movable pulley.
