A crush course on why though the elements had been categorized according to their properties before, it is Mendeleev's periodic table that survives to our days.
The idea of a redox reaction and the excessive production of gas is culminated in this fun demonstration for young children (the awe effect of producing this elephant toothpaste) and older ones that understand the notions of a redox reaction
This powerful film from MullenLowe London provocatively captures how, early on in their education, children already define career opportunities as male and female. When asked to draw a firefighter, surgeon and a fighter pilot, 61 pictures were drawn of men and only 5 were female.
Buiding a homemade camera, it may seem difficult, but it is easier than it seems, because for only two dollars and in 5 minutes, everyone can build their own cardboard camera.
The visible absorption and photoluminescence of CdSe nanoparticles depend on the size of the particle. A sudden injection of room temperature selenium solution into hot cadmium solution produces quickly-growing seed crystals. Samples are withdrawn from the hot solution and quenched at room temperature to produce a series of increasing particle sizes and observable change in color.
The homemade elctroscope consist of a vertcal copper metal rod, which has a kind of sphere on the top and at the opposite end two sheetd or flakes of aluminum foil. When an electrified object is brought closer to the sphere, the rod is electrified and the electrically charged aluminum lamellae repel, separating.

Making a homemade radio is easier than it seems. Thanks to this video, we will learn how to create a homemade radio in a fun way and using materials available for everyone.
Air is a gas and as such has the property of expanding, increasing its temperature, that is to say, increasing its volume and on the contrary, when this gas decreases its temperature, it tends to contract and with it to decrease its volume.
