Bonding

We started this journey with a demonstration of conductivity. We did this by using a pickle to complete a circuit, creating an orange glow in the pickle. This demonstrated the electrons getting excited and emitting light. Through this we also learned that the saltier the pickle, the more conductive it is.

In this experiment, we put salt and water in a dish and separated the two by boiling the water out of the dish, leaving the salt. This works because water has a lower boiling point compared to salt allowing the water to evaporate leaving the salt in the dish.

At one point we were given 6 unknown solutions and had to figure out what they were. The only information we were given, was the color that two samples turned when they were mixed together. With this is information, we used the process of elimination to find out what each sample was.

In our experiment of seeing whether salt or sugar would complete a circuit and turn on a light, we were also able to experiment with other objects like this apple slice, which indeed did complete the circuit.

In this demo, C4 was added to water to show how the number of bonds effects the amount of energy is released when they break. You can see this in different types of explosions, depending on how loud and quick the explosions occurs.

One day chemistry class became yoga class. We used different yoga poses to learn the different shapes of covalent bonds.

During our third journey in Chemistry, we learned about ionic and covalent bonds, and the differences between them. We learned how to draw a Lewis structure and how you can use the structure to find out things about the compound. Through Lewis structures, we were able to see how the shape of a compound can effect how it works and what form it is in. This is called molecular geometry. We studied this concept through organic chemistry and specifically opioids, to understand how the shape of a molecule has an effect on the body. We were put into groups and did projects on specific opioids, my group studied heroine. It was super interesting to see how a molecule can disguise itself as something that our body makes, attaching itself to the opioid receptors. I think one of the most confusing parts of this journey was the organic chemistry structures and how many parts are left out of them. Overall this was a very interesting unit and I can’t wait to continue to build on the things we have learned.
