Today in technology I explored a Nearpod about the adhesive glue. In the Nearpod I learned many things about different kinds of glue, the history of glue, and watched a demo of somebody showing different ways we can use PVA glue to make joints. One thing I learned from this Nearpod was that glue wasn’t always used for gluing things together, like paper and cardboard. In 70,000 BC they used glue to make their cave drawings last longer. But over the years glue became to be used like we use it today. I also learned glue wasn’t always made out of rubber or Polyvinyl alcohol, years ago they were made of dead horses and milk. I also learned about the setting and curing. Setting is the amount of time it takes for glue to become solid, and curing is the amount of time glue takes to be it’s maximum strength. Most of the time, the setting and curing of glue is different for each brand and sometimes different because of the weather outside. I also learned a lot from the demo I watched. I could see only from the video that there are so many ways to join material in any position with glue. I found this interesting because I didn’t know glue could do so many things. I also didn’t know many things that I learned in this nearpod, like the setting and curing of glue, how glue was used for cave paintings in early years, and glue wasn’t always made out of the material they make it today. I really enjoyed learning from this nearpod, and now I know so many different things that are super interesting and I didn’t know before.
