For this round of STEM, I’ve enjoyed learning the lesson and got to do many experiments. Basically, the topic that we focused on was “Carbon”! Well, the mini-lessons in this topics were hydrocarbon, properties of carbon, and the carbon cycle.
For the lesson, we were assigned to answer ten questions that were written down on a paper. Actually, that was not a test but it was the guiding questions that helped us to understand the lesson better. To make it even more clear to understand, we did an experiment called Black Snack Experiment.
For the black snack experiment, we put aluminum foil on a bowl. Then we filled the bowl with sand. After that, we put 5g of baking soda and 20g of sugar and mixed it together. Then, we put it in the bowl. The next step is that we need to pour some alcohol all over the bowl. Finally, we just need to fire the matches and put them in the bowl. Those were the instructions. After we put the matches into the bowl, the black ashes rise up like a snake. It has a shape like a snake. The ashed felt like styrofoam, but when we squeeze it harder, it broke and turn into normal ashes.
It was a very exciting round of STEM. Thank you for reading and visiting my portfolio. Have a wonderful day!
