Learning Resources Science Kits for Kids Age 3+, STEM Projects

Learning Resources Science Kits for Kids Age 3+, STEM Projects of Weathervane Periscope Telescope Roller, 4 Sets Scientific and Physics Educational Teaching Aids for Primary School Students
- This Science and education suit consists of 4 items. These four items can be DIY completed by oneself, with simple installation, which not only exercises hands-on skills but also learns relevant principles. It’s good STEM kits for kids and educational toys for kids, it’ll also be a good homeschool supplies and super gift for children.
- A weathervane is an asymmetrically shaped object with a center of gravity fixed on a vertical axis. When the wind blows, the end that produces greater resistance to air flow will rotate with the wind to show the wind direction. The arrow of the weather vane always points to the source of the wind. The principle is actually very simple: the area of the arrow tail exposed to the wind is larger than that of the arrow.
- A periscope is a special tool that helps submarines and other vehicles see things without being seen. When a submarine is underwater, it's hard to see what's going on above the surface. But with a periscope, the submarine can use mirrors to look up without popping its head out of the water.
- Telescope is an optical instrument of observing distant objects by using lenses, mirrors, and other optical devices. Telescopes are composed of an eyepiece and an objective, classified as Galileo telescopes and Kepler telescopes. Galileo telescope: The eyepiece is a concave lens, while the objective lens is a convex lens that can see an upright and magnified virtual image. Kepler telescope: the eyepiece is a convex lens, and the objective lens is also a convex lens. You can see an inverted and
- The roller is pushed by hand, it is given a power and pushed to start manually. During the rolling process of the roller, the hanging nut causes the rubber band to continuously twist and deform, just like twisting Fried Dough Twists, at this time part of the kinetic energy is converted into elastic potential energy. Before the roller stops rolling, the rubber band will resume deformation and drive the roller to move in the opposite direction. The potential energy is converted into kinetic ener
