The hot summer weather allows the children to only hide in the cool house, then the children know that hot heat is also magical energy, called convection. Today, the alpha science classroom explains the phenomenon of weather convection to children in the form of kid's science experiments and presents the hidden physical science experiments in nature to children to learn the magic of it.

Alpha Science Classroom: Production Steps of convection spiral snakes
1. First, the children can print out the picture of the snake or draw it by themselves.
2. Secondly, children can color and decorate as they wish.
3. Then, the children carefully cut the snake to make it spiral.
4. children thread the cotton and tie a knot at the end.
5. children pass it through the dots on the tail.
6. children carefully put it on the heat source... a lamp has been on for a while but is very effective on the stove, or a candle.
Remind the children to pay attention to the Alpha Science Classroom and remind them to take it to the place where it may go, please pay attention to this point. The supervision of children is safe, and this is safe.
Alpha Science Classroom: The scientific principles behind convection spiral snakes
The Alpha Science Classroom tells the children that convection is passing in the fluid. Fluid is usually fluid or fluid!
As far as snakes are concerned, movement is air molecules. As the molecules near the heat source heat up, they will go further. This appearance (or air) decreases, so it rises, and is taken up by colder, thicker molecules. This circulation of air particles rises and falls, causing the snake to spin. The molecule falls as it rises, re-closes (increases density), and sinks again, continuing the cycle. This cyclical rise and fall of air particles cause rotation.
Did the children's convection spiral snakes begin to spin? The children have solved this magic mystery! Alpha science classroom hopes that children can learn simple scientific knowledge, explore more kid's science experiments and become the interesting physical science experiment activity of convection snakes.
Alpha science toys have created a magical scientific world for children, which is full of scientific knowledge to help children realize the dreams of scientists!
