  1. Edible science PROCEDURE Pour juice into the smaller zip-lock bag.  Squeeze out excess air and seal. Place the small bag filled with juice inside the larger bag. Fill the larger zip-lock bag with crushed ice so that it surrounds the juice bag. Add salt to the ice liberally. Squeeze out excess air and seal the large bag containing everything. Massage and shake the bag so that the salty ice is constantly coming into contact with the juice bag. Continue squishing for 5-10 minutes, observing the changes in how the juice looks and feels. MATERIALS

  2. WHATHAPPENS? The juice gradually solidifies and turns into a SLUSHY! Water freezes at 32ºF / 0ºC Adding an impurity (salt) to ice lowers its freezing point. The ice wants to melt back to water, but to do this it needs to absorb heat from somewhere – in this case, the juice.  Heat is transferred from the juice to the ice, freezing the juice. This is an endothermic process (heat is absorbed).

  3. Como hacerhelado en 10 minutos MATERIALES PROCEDIMIENTO Introduce el jugo en la bolsa zip-lock pequeña. Sella la bolsa y asegura que no quede aire adentro. Introduce la bolsa pequeña con el jugo dentro de la bolsa zip-lock grande. Llena la bolsa grande con hielo. Agrega sal al hielo. Sella la bolsa grande. Agite la bolsa para que el hielo con sal constantemente haga contacto con la bolsa pequeña con jugo. Continúe agitando por 5 a 10 minutos y observe el cambio en el jugo.

  4. Explicación El jugo se convierte en un HELADO! El agua se congela a 32ºF / 0ºC Añadir sal al hielo rebaja su punto de congelación El hielo quiere derretirse, pero para poder hacer esto, absorbe el calor del jugo. Esto se llama reacción endotérmica. El jugo recoge el frío del hielo y se convierte en helado.

  5. GUMDROP STRUCTURES MATERIALS PROCEDURE Build a tower by sticking toothpicks into gumdrops. The gumdrops are the connectors. Place the structure on the Jello tray. Agitate the Jello tray to simulate an earthquake. This will test the stability of the structure. Watch what happens…

  6. Estructuras de Dulce MATERIALES PROCEDIMIENTO Tome los palillos y encájalos dentro de las pastillas de goma para construir una torre. Las pastillas de goma funcionan para conectar los palillos. Ponga la estructura sobre la bandeja de gelatina. Agite la bandeja de gelatina para simular un terremoto. Observe como funciona la estructura…

  7. EXPLODING LUNCH BAG MATERIALS PROCEDURE Put ¼ cup of warm water into the zip-lock bag. Add ½ cup of vinegar to the water in the bag. Put 3 teaspoons of baking soda into the middle of the tissue. Wrap the the baking soda up in the tissue by folding the tissue around it. Partially zip the bag closed but leave enough space to add the baking soda packet. Put the tissue with the baking soda into the bag and quickly zip the bag completely closed. Put the bag in the bucket and step back. The bag will start to expand, and expand, and if all goes well…POP!

  8. WHATHAPPENS? The baking soda and the vinegar eventually mix (the tissue buys you some time to zip the bag shut) When they do mix, you create an ACID-BASE reaction and the two chemicals work together to create a gas (carbon dioxide – the stuff we breathe out) It turns out gasses need a lot of room and the carbon dioxide starts to fill the bag, and keeps filling the bag until the bag can no longer hold it any more and….

  9. BOLSA EXPLOSIVA MATERIALES PROCEDIMIENTO Introduce ¼ taza de agua tibia a la bolsa de zip-lock. Añade ½ taza de vinagre a la misma bolsa de zip-lock. Añade 3 cucharaditas de bicarbonato sódico en el medio de la toalla de papel y pliégala. Selle la bolsa de zip-lock parcialmente permitiendo suficiente espacio para poder añadir la toalla de papel con bicarbonato sódico. Añade la toalla de papel con bicarbonato sódico y selle la bolsa rápidamente. Ponga la bolsa dentro del cubo. La bolsa se expande hasta que…POP!

  10. Explicación El bicarbonato sódico y la vinagre eventualmente se mezclan. La toalla de papel permite que la reacción se atrase para que tengas suficiente tiempo para sellar la bolsa. Cuando estos se mezclan, ocurre una reacción acido – base y los dos químicos se unen para crear un gas. Este gas es dióxido de carbono. Resulta que los gases necesitan mas espacio, por lo cual llena la bolsa y eventualmente….
