I then give them a day to explore their element. I try to make this very active and personal to them. We look back at the Noble gasses with that number 8. How they shared outer electrons for what I would call the ‘magic number 8’. Then we explored why a column 1 element would have such a stable combination with a column 7 element to make a compound like NaCl. We explored the reactivity of column 1 and column 7 elements and no reactive column 8 elements. “All elements with one electron in outer shell please stand” Etc. Later as we looked at models of electron models (Bohr) we explored electron shells and outer number of outer shell electrons. Relationship with Atomic Mass and proton and neutron total. I would ask them to guess the next elements number of protons. We then explored number of protons and neutrons, to discover their relationship to Atomic Number. I then pointed out that these are characteristics that we would investigate along with others. Once seated I asked “everyone who has a grey/silver metal please stand, notice where you are.” “Everyone who is colorless or have a non grey/silver color please stand.” “If you’re a solid please stand.” “if you are not a solid please stand. For the week the students were called on by their Element name. I set up the classroom to have 8 seats across and begin reseating the students by atomic number, to mirror the Periodic Table with students. It listed Element Name, Element Symbol, Atomic Number, Color, Natural State, Number of protons, neutrons, electrons, Atomic Mass, electron shells, number of electrons in outer shell. I would hand out to each student an Element sheet. r/ECEProfessionals early childhood education r/TeachingResources: Share and discover teaching resources, such as demos, blogs, simulations, and visual aids. r/Teachers: Learn about and discuss the practice of teaching, receive support from fellow teachers, and gain insight into the teaching profession. r/Education: Learn about and discuss the news and politics of education.
