Introduction
Atom, smallest unit into which matter can be divided without the release of electrically charged particles. It also is the smallest unit of matter that has the characteristic properties of a chemical element. As such, the atom is the basic building block of chemistry. Investigate varying electron configurations in electron shells around an atom's nucleus Most of the atom is empty space. The rest consists of a positively charged nucleus of and neutrons surrounded by a cloud of negatively charged electrons. The nucleus is small and dense compared with the electrons, which are the lightest charged particles in nature. Electrons are attracted to any positive charge by their electric force; in an atom, electric forces bind the electrons to the nucleus.
Task
Step 1: students will build a model on atoms.
Step 2: Students will be required to choose an element and identify the number of protons/neutrons/electrons
Step 3: Students will watch the following video: What Is An Atom And How Do We Know? - Bing video
step 4: students will fill in a WKL worksheet
step5: Students will be asked to read the following website Atoms - What are they? What's inside them? - Explain that … and
Process
Students will start by interacting with a presented PowerPoint on Atoms, to learn more about what atoms are made up off and the charge of the molecules. After that, students will proceed to work in pairs to fill the KWL chart. Then they will proceed to build their own model on given chemical elements. at the end of the session students will be asked to answer some questions to wrap up the session and check for understanding. then students will proceed to sit for a written evaluation on the topic.
Evaluation
Students will be evaluated on:
1)their ability to build a model correctly
2) their ability to answer the questions asked at the end of the session
3) a written evaluaion
Conclusion
I will be wrapping up the session by highlighting the important topics discussed in today's class. Then, students will share what they learned in today's session. Additionally, they will proceed to share with their classmates what they think about something new they learned today. Moreover, I will be asking questions to test their knowledge and ask open ended question to arouse their curiosity.
