Elements and their symbols
Atoms, elements and the periodic table
CCSS NGSS.MS-PS1-1England: KS3 Chemistry: Atoms, elements and compounds
Objective and success criteria
Students will: Elements and their symbols.
- I can answer questions on today's skill on my own, without help.
- I can explain each step and say why it works.
- I can check my answer and spot a mistake.
Before and after
Needs first: no earlier skill in the map; start from what students know.
Leads to: Elements, compounds and mixtures; The periodic table: groups and periods
Materials: Periodic tables, Atom model kits, Mini whiteboards, A diagram or short video clip of the idea, Printed student sheet (below).
Warm-up · 6 min
- Quick retrieval: three short questions students should already manage. Answers on mini whiteboards.
- Show answers together and note who needs support in the main task.
- What is the chemical symbol for calcium? (Cl / Li / Cm / Ca) → CaPrompt: Symbols have one capital letter, sometimes followed by a small letter.
- Which element has the symbol K? (oxygen / potassium / aluminium (aluminum) / nitrogen) → potassiumPrompt: Some symbols come from Latin names: Fe (ferrum), Cu (cuprum), Na (natrium), K (kalium), Ag (argentum), Au (aurum), Pb (plumbum).
- Type the chemical symbol for copper. Use a capital letter, then a small letter if needed. → CuPrompt: It may come from the Latin name.
Hook · 6 min
- Show the periodic table and ask what patterns students can see before anything is explained.
- Share the objective: Elements and their symbols. Read the success criteria together.
I do: model it · 12 min
- Work through the example out loud, saying why you do each step, not just what you do.
- Example: What is the chemical symbol for nitrogen?
- Step 1: nitrogen → N
- Step 2: So the answer is: N
- Answer: N
- Pause after each step and ask a student to say what comes next.
We do: guided practice · 12 min
- Do these together. Students try each step on whiteboards before you reveal it.
- Use the hints as prompts rather than giving the answer.
- What is the chemical symbol for oxygen? (O / Li / Si / Ox) → OPrompt: Symbols have one capital letter, sometimes followed by a small letter.
- Which element has the symbol He? (helium / hydrogen / sodium / phosphorus) → heliumPrompt: Some symbols come from Latin names: Fe (ferrum), Cu (cuprum), Na (natrium), K (kalium), Ag (argentum), Au (aurum), Pb (plumbum).
You do: independent practice · 17 min
- Students work on the student sheet. Circulate and check the first two answers of every student early.
- Students who finish: write a question of their own for a partner, with the answer.
The 8 questions are on the student sheet below, with answers in the key.
Exit ticket · 7 min
- Two questions on their own. Sort answers into got it / nearly / not yet to plan the next lesson.
- Which element has the symbol Si? (iron / carbon / potassium / silicon) → siliconPrompt: Some symbols come from Latin names: Fe (ferrum), Cu (cuprum), Na (natrium), K (kalium), Ag (argentum), Au (aurum), Pb (plumbum).
- What is the chemical symbol for phosphorus? (P / Li / Ps / Ne) → PPrompt: Symbols have one capital letter, sometimes followed by a small letter.
Watch out for
- Everyday meanings of words getting in the way of the science meaning: define key words explicitly.
- Remembering facts without the reason: ask "why?" and "what is the evidence?"
Support and stretch
Support
- Use concrete materials: periodic tables.
- Give the first step of each question, or a partly worked example to finish.
- Pair with a confident partner for the guided practice.
Stretch
- Move on to: Elements, compounds and mixtures; The periodic table: groups and periods.
- Explain a common mistake in writing and how to fix it.
- Write a word problem that uses today's skill, then solve a partner's.
