Mar 3, 2017 · The Atoms Family in Grade 3 “Us primary [kids] are much brighter than grown ups think! We hear about atoms all the time on the Big Bang Theory and The Simpsons, so why have they decided to keep atoms a secret in primary school?”

At the start of the 20th century, J.J. Thomson did experiments to learn about the atom. He showed that positively-charged and negatively-charged particles made up atoms. What he was not sure about was how they fit together. His idea at the time was that the negative electrons were stuck into a positive sphere. He imagined that the atom looked like ...
Scientists’ understanding of the atom changed in 1911. This was due to the gold foil experiment done by Ernest Rutherford and his team. In their work, they saw that the positive charge of atoms seemed to be concentrated at their centres. Rutherford called this the nucleus. He also predicted that the electrons would orbit the nucleus, like planets a...
Rutherford’s planetary model explained a lot. But it didn’t answer some questions that scientists still had. They wondered where the electrons actually were. Could their location be predicted? They also wondered why the orbiting electrons didn’t lose energy and crash into the nucleus. Luckily, Danish scientist Niels Bohrwas trying to find those ans...
The Bohr Model quickly became popular. We still use it today because it helps us understand how and why atoms interact with each other. But scientists were not finished trying to understand how atoms look. In 1926, Austrian physicist Erwin Schrödinger took Bohr’s model a step further. He proposed a model which described the likelihood of finding an...

By examining communities in India, Tunisia, Peru, and Ukraine, they will discover common needs and how people’s quality of life varies around the world. Your child will explore the concept of a global community and Canada’s role within it. For more information about Grade 3 Social Studies, refer to the program of studies.
Jan 13, 2024 · Most interactions among atoms take place in the outermost shell of each atom. The number of each electron in this shell determines how an atom combines with other atoms to form compounds. When atoms combine, they gain, lose or share electrons in such a way that the outer shells become chemically complete.

Watch related TV shows like Magic School Bus or Bill Nye, play online games, do experiments, and let your child be a natural scientist. Social Studies, di vide the year into 3 units of about 12 weeks each, two times a week (24 lessons for each.) Some subjects may need more time and that's okay.
