Materials:
Process:
Safety Hazard:
Hot plate safety- Keep hot plate in the middle of the table, make sure everyone around you knows that hot plate is in use, stay around hot plate at all times, and when done using put a sticky note saying “Caution, Hot.”
Wear gloves, goggles, and limit skin exposure, so none of the hot mixture burns skin.
Clean Up:
After bismuth is hard, tap the container top get all of the crystals out, also wipe down stirrers.
Documentation:
We will take pictures throughout the entire process.
Science:
Bismuth forms trivalent and pentavalent compounds, the trivalent ones being more common. Many of its chemical properties are similar to those of arsenic and antimony, although they are less toxic than derivatives of those lighter elements.

Safety Hazard:
The materials we are working with are not supposed to be eaten.
Clean Up:
We will wipe down all of our surfaces and materials.
Looking Back:
In class we got to do a really cool and scientific experiment. We got to melt a metal, known as bismuth. While melting the bismuth I worked with Lydia. I think we worked well together, and we were very patient. When we melted the bismuth, it took us two days, because the crystals wouldn't form, so we repeated the process 5 times. I thought that melting bismuth would be a quick process, but it took us a while to get it right. Something that I would change would probably to put more bismuth into the small container, because we put in more the last time we tried it and it worked, so I would've done that earlier.
Looking Beyond:
Bismuth is a heavy metal and it really easy to break. Bismuth forms trivalent and pentavalent compounds, the trivalent ones being more common. Many of its chemical properties are similar to those of arsenic and antimony, although they are less toxic than derivatives of those lighter elements.Also when you melt bismuth the properties change from solid to a liquid, so there is different phases of matter.
Looking Inward:
The project ended up to be successful at the end, and after many tries. At the end we got a pretty crystal and desirable results. I think we got desirable results, because we waited patiently, and we filled the small container to the top, after we did that we finally got crystals. My partner and I had had to wait, but the results were worth it.
Looking Outward:
While melting the bismuth I just worked with Lydia, so far I have been working with Lydia for all of my projects. I like working with her, because we get along well and we are able to communicate really well. I think we were well prepared for the bismuth, because we had everything planned out the day before.
Looking Forward:
In this group I worked with Lydia. I think we both contributed well, because we communicated, and were able to complete the project. I think we both did a good job, even though most times it wouldn't work, but we were able to get the one crystal. I was able to contribute effort. I think we both communicated, and collaborated really well. I also was able to get some pictures from the bismuth.
Take Away:
Melting bismuth took so long but the results turned out great. Melting bismuth is fairly easy you just have to be aware of your surroundings, and you have to make sure you don't burn yourself. To melt bismuth turn hot plate on. Put bismuth in metal pan and put on hot plate. Wait for it to melt. When bismuth is fully melted wait for it to cool down.When it starts to harden gently poke it, and pick out any crystals with tweezers.Overall it was a good project to do and the crystals were so beautiful.
