one balloon
1 plastic bottle ( 600 ml . Approx. )
½ cup white vinegar
1 funnel
1 tablespoon
1 elastic band
Sodium Bicarbonate
How to:ExperimentsVerter white vinegar in the plastic bottle . Using the funnel , add two tablespoons of baking soda ( can be easily obtained at any pharmacy ) inside the balloon . Place the balloon in themouth of the bottle , taking great care that the baking soda does not fall within the same ( see the video to understand better) and secure the opening with a rubber band . Once ready , now to dump bakingsoda inside the balloon content . Observe what happens .
What happens ?
As you can see the balloon inflate itself seems , but in reality it is a chemical phenomenon . What happens in this..
Experimentos de química en inglés:
Experimental chemistry is the science of observation. We pose a question to nature, carry out the corresponding experiment, and observe the outcome. What happens if we mix two substances? If we blast a molecule with a laser, what will it do? If we introduce a biomimetic into a living organism, how will it respond? Experiments produce data that relate to each individual observation.
Here are some science activities that allow us to do experiments and projects with materials we likely have in our cupboards already:
- Make a Borax Snowflake: making a borax snowflake is a crystal-growing project that is safe and easy enough for kids. You can make shapes other than snowflakes, and you can color the crystals. As a side note, if you use these as Christmas decorations and store them, the borax is a natural insecticide and will help keep your long-term storage area pest-free. If they develop a white precipitant, you can lightly rinse them (don't dissolve too much crystal).
- Explore Penny Chemistry: you can clean pennies, coat them with verdigris, and plate them with copper. This project demonstrates several chemical processes, yet the materials are easy to find and the science is safe enough for kids.
- Make a Seven-Layer Density Column: make a density column with many liquid layers. Heavier liquids sink to the bottom, while lighter (less dense) liquids float on top. This is an easy, fun, and colorful science project that illustrates the concepts of density and miscibility.
Saber experimentos de química en inglés puede ampliar el conocimiento científico y lingüístico del individuo, es por eso que es fundamental trabajar estas áreas intelectuales del ser humano.
