Framework Chemistry 14 An Inquiry Based Science Teaching and Learning Framework Topic/Learning Activity OC39 & OC40 Student Cohort Student Level 2nd year. Prior Knowledge Students will have studied ■■ Classification of substances. ■■ Properties of substances. ■■ Metals and non-metals. C14 Stimulus to Engage ■■ Discussion on students’ understanding of an atom – atom bomb, splitting the atom, atomic ant, etc. ■■ Refer back to separation of mixtures – mixture v pure, etc. ■■ The Elements Song http://www.youtube.com/watch?v=jNoMZVm-J08&feature=fvwrel Science Questions Initial questions leading to the questions students will work on during the activity: ■■ From The Element Song, can you recognize any of the elements? ■■ What makes one element different from another? Are they the same size, same mass? ■■ What do we mean by charge? Learning Outcomes Content Knowledge: The students will be able to: ■■ Describe the structure of an atom. ■■ Identify the sub-atomic particles, their charge, location and relative atomic mass. ■■ Distinguish between atomic number and atomic mass. ■■ Distinguish between two different atoms. ■■ Distinguish between isotopes. ■■ Identify the first 20 elements and draw their Bohr structure. ■■ Identify a molecule which has Ionic Bonding. ■■ Identify a molecule which has Covalent Bonding. Process: ■■ Arrange the sub-atomic particles in an atom. ■■ Organise the electrons in their shells around the nucleus. ■■ Arrange the sub-atomic particles in atoms within a molecule. ■■ Drawing Bohr diagrams. Ch em istr y Framework Chemistry 14 An Inquiry Based Science Teaching and Learning Framework Skills: ■■ Work as part of a team to complete a task. ■■ Communicate effectively. ■■ Classifying and ordering information. C14 Ch em Questions during Activity Questions to drive student learning (directing them to the learning outcomes): ■■ What is the symbol for your element? ■■ Where would you show the protons and neutrons in the atom? ■■ Where would you show the electrons in the atom, how would you place them around the protons and neutrons? ■■ Can you show where you would find the protons, neutrons, electrons in the atom? ■■ How can you represent the element on paper? ■■ How can you distinguish isotopes? istr Questions to probe understanding ■■ How do you know how many protons are in the atom? ■■ How do you know how many neutrons are in the atom? ■■ How do you know how many electrons are in the atom? ■■ What is the relationship between the number of protons and the number of electrons? ■■ What particles make up the mass of the atom? ■■ Why are the electrons not included as part of the mass number? Questions to get students thinking about their own learning (metacognition): ■■ What makes an atom of a certain element unique? ■■ How are the elements organized in the periodic table? ■■ Why are some elements at the left hand side and others at the right hand side? Developing the Activity How do you stimulate students to ask even more questions/think further? ■■ How do you think molecules are formed? ■■ What is meant by “splitting the atom”? ■■ What is an Atom Bomb? 2 y Framework Chemistry 14 An Inquiry Based Science Teaching and Learning Framework Possible supporting activities: ■■ Take simple compounds like Sodium Chloride and Magnesium Oxide and represent them with coloured Cheerios. Questions for supporting activities: ■■ Do atoms retain their properties when they become part of a molecule? ■■ What happens the electrons in each of the atoms when they are in a molecule? Additional Resources C14 Ch em Stimulus materials, websites, etc. ■■ The element song - http://www.youtube.com/watch?v=GFIvXVMbII0 ■■ Daniel Radcliff singing the song - http://www.youtube.com/watch?v=rSAaiYKF0cs&feature=related ■■ Atom Bonding Model - http://www.youtube.com/v/83uBVif653Y&fs=1&source=uds&autoplay=1 How has the use of ICT enhanced the learning?
