Teenii STEM Physics Science Lab Basic Circuit Learning Starter Kit Electricity and Magnetism Experiment for Kids Junior Senior High School Students Electromagnetism Elementary Electronics LERBOR

Description

Thinking, Observing, Questioning and Experimenting Teenii
(originally named LERBOR) educational toys cover a wide range of subjects and
include science kits, coding kits, robotics kits, and more. They are not just
motivational and fun. They can also sharpen students’ powers of observation,
stimulating questions. And they are the key to enhanced learning,
clarification and consolidation of theory. Teenii STEM Basic Circuit Learning
Kit Electricity and Magnetism Experiment This kit is an excellent gift for
kids to learn AND understanding the science and mathematics behind electricity
and magnetism. The included manual also gives simple but concise explanations
about each piece included in the kit. It’s got all necessary components
including voltage, ampere meter, mini lightbulb, generator, motor, magnets.
Simply follow the instructions to conduct different experiments and explore
the world. 3 AA batteries required. Recommended for ages 12 and up. Younger
kids should be under parents’ supervision and guidance. Read more Real
components instead of abstract ones Unlike the other abstract kits with which
kids will have great fun playing with it but hardly learn or understand what
they are doing, everything in this kit is open and naked to the eye. By
reading the manual and doing the experiments, kids will learn about basic
rules in parallel and series circuit; schematic diagrams drawing; the
relationship between voltage, current and resistance; magnetic effect of
electric current etc. With this kit, kids will learn the principles behind
electric circuits and why they work in the manner they do. Moreove, Moreover,
you can literally do probably a hundred experiments by tinkering with all the
components or things you can find around the house without following the
instruction of the manual. Read more Learning about magnets When a magnet
touches a nail, smaller metal pieces can be attracted to the nail, as shown in
the picture. The nail itself becomes a magnet which causes the nail to become
polarized. If you pull away the magnet, the nail loses some of its
magnetization and will no longer exhibit as much attraction for other metal
objects. If you touch a magnet to a piece of soft iron (iron with a low carbon
content) replacing the nail, after you pull away the magnet, the iron loses
all of its attraction for the other metal objects. This is because soft iron
is a temporary magnet. Creating a Fruit Battery In this experiment, you will
make a battery with fruits and learn about the principle of the wet cell
battery. The chemistry behind the fruit cell is that zinc is more reactive
than copper which means zinc loses electrons more easily than copper. As a
result, oxidation occurs in the zinc metal strip and zinc metal loses
electrons which then become zinc ions. The electrons then flow from the zinc
strip to the copper strip through an external circuit. Making a Hand-crank
Electric Generator In this experiment, you will make a hand-crank generator
with an electric motor and learn about the working principle of electric
generators. The electric generator, invented by Michael Faraday, converts
mechanical energy to electrical energy. An electric generator consists of a
number of wire loops placed in a strong magnetic field, which is similar to
the electric motor. When the wire loops rotates, it cuts magnetic field lines.
So the current is generated in a circuit. Building a Electric Raning Bell In
this experiment, you will build an electric bell with batteries and a solenoid
and learning the mechanics of the original ranging bell. When the switch is
pressed, current flows around the circuit. The soft iron core is magnetized by
the magnetic field produced by the current in the coil. Then soft iron
armature is attracted and moves towards the soft iron core. Hammer moves to
hit the gong and produce a sound. Contacts open to switch off the current.
Soft iron core loses its magnetism. Spring brings the soft iron armature back
to its original position. Contacts will close to switch on the current again.
The process repeats so the bell keeps ranging. Temporary Magnet Fruit Battery
