Atoms Blog Reflection
By: Kierra Long
Ok. So today in class we did an atom’s lab. We used 4 straws and 4 pieces of tape in this lab. So we took two pieces of tape and taped them to our desk. Then we took another 2 pieces of tape and taped them on top of the other pieces of tape. Then we stuck one task tap to one straw and one tape tape on another and stuck the straws together. We did the same for the other set of desk tape and tape tape.
We discovered that when you bring one of the straws with des tape on it and a straw with tape tape on it, the pieces of tape are attracted to each other! However, when you bring a desk tape straw and another desk tape straw together, the completely repel each other! Like people say, opposites attract!!! The atoms in one strip of tape were positive and the other negative. Therefore the reason why they would either repel or attract each other! We also learned that over time scientists have discovered certain materials can react to each other to create a positive or negative charge. Like with the tape! PVC pipe being rubbed with a cotton cloth repelled the tape! All the protons and electrons and everything has been studied by scientists to remember this.
We are always making great discoveries! MORE and MORE every day!
