4C Science : Big Bubble Experiment

#SobatInovator, have you ever done an experiment? If yes, that’s awesome!  An experiment is an action or special observation carried out to test an opinion that is estimated to be true. Therefore, through experiments, we learn to observe, investigate, test and build hypothesis.  Learning science and simple experiments can provide great benefits, especially to foster curiosity and exploration, which are necessary 21st century skills.

Luckily, our foundation has collaborated with Einstein Science Project, an enrichment program that focuses on science experiments for kids, to design and train experiments for us. The experiments are designed to use simple elements that can be found easily in many areas. The children at TBI Joseph Hendry Library recently conducted a simple science experiment called the Big Bubble experiment. In this experimental activity, the participants were  4th-, 5th-, and 6th-grade students. The activity was divided into 3 groups, with each group having a different color of bubbles. Experimental activities are routine activities held by Taman Baca Inovator for all TBI library visitors.

#SobatInovator, Are you curious about the Big Bubbles experiment conducted at TBI Joseph Hendry Library in Southwest Sumba?

Tools and materials:

  1. Plastic Cup
  2. Citron
  3. Baking Soda
  4. Liquid Soap
  5. Spoon
  6. Food Coloring

Steps :

  1. Prepare a plastic cup
  2. Pour water up to half a glass
  3. Add 1 tablespoon of citron powder, mix well
  4. Add food coloring, stir until dissolved
  5. Add 1 tablespoon of baking soda
  6. Observe the reaction that occurs

It was easy and fun! Immediately the children ask for more experiments to be conducted. This proves that learning experiments from an early age also helps develop a mindset of curiosity.

#SobatInovator, if you have prepared the tools and materials, you can also try this! Through our experimental activity, Kak Merlin explained the process that occurs in the mixture of substances that causing the foam or bubbles to be formed. A new form of substance was produced, and the bubble was created as the result of a mixture of several substances and a combination of 2 different states of matter, namely liquid and gas. The gas contained in the bubbles is trapped by the liquid on the outside so that foam or bubbles are formed. The reaction that occurs in the Big Bubble experiment is an endothermic reaction that absorbs heat or heat from a mixture of citron and baking soda, as a result of the endothermic reaction making the mixture feel cold. After the reaction is complete, the temperature will slowly return to normal. #SobatInovator, another example of heat absorption or endothermic is when an ice cube melts after being placed in a glass at room temperature.

#SobatInovator, did you successfully try the Big Bubble experiment? If it doesn’t work, try again! Observe hat occurs when some substances are mixed. If it is successful, you can also teach your friends and directly practiced together with your friends. Experimental activities are very fun!

 Be curious just like our kids at TBI Joseph Hendry!
