Tiempo vs. Clima Activity for Kids
Veleta DIY
Duration: 30-60 min
Difficulty: Media
Cost: $0 a $5
¡Construye un dispositivo que te diga en qué dirección sopla el viento!
Material List
1 Pajita de plástico
2 Platos de papel
1 Marcador
1 Lápiz con borrador nuevo
1 Tijeras
1 Rollo de cinta
1 Cartulina
1 Alfiler recto (¡para uso exclusivo de adultos!)
1 Regla
1 Tubo de plastilina
1 Ventilador de mesa
Instructions
1 En la parte inferior de un plato de papel, usa un marcador para escribir N, E, S, W (en el sentido de las agujas del reloj).
2 Corta en la cartulina la punta y la cola de una flecha. La cola debe ser mucho más grande que la punta.
3 Haz cortes de 1 pulgada de largo a lo largo en ambos extremos de la pajilla.
4 Desliza la punta y la cola de la flecha por las ranuras.
5 Por separado, aplasta una gran bola de plastilina entre los dos platos.
6 Empuja el lápiz a través del plato donde escribiste N, E, S, W de tal manera que quede derecho y firme.
7 Pídele a un adulto que empuje sin apretar el alfiler a través del centro de la pajita y dentro del borrador del lápiz.
8 Prueba la veleta usando el ventilador para representar el viento.
9 Si sales al exterior, usa una brújula para alinear el norte en tu plato para mayor precisión.
How It Works
Una veleta es un instrumento que puede medir la dirección del viento. El viento es aire en movimiento y empuja la cola de la veleta, lo que hace que gire de manera que la flecha apunte en la dirección desde la que sopla el viento. Puedes probar esto usando un ventilador. Esta veleta muestra la dirección del viento, pero es el usuario quien debe registrar esta información. Junto con la temperatura, la presión y la precipitación (lluvia), la velocidad y la dirección del viento son medidas importantes para comprender y predecir el clima.
