I use this technique a lot. Students have to convert the 8 sentences into diagrams - hence "Draw the sentence". This is a great assessment exercise and is linked to my TES article at http://www.tes.co.uk/article.aspx?storycode=6112077
This is an easier one as both have equal but opposite charge - slightly harder examples have also been uploaded.
This infographic for A-level chemistries students briefly explains how lithium-ion batteries and related battery chemistries like sodium-ion and magnesium-ion batteries work. Due to the low abundance of lithium on Earth, lithium-ion batteries will have to be replaced by these other chemistries in the future. They do, however, work on the same principle as lithium-ion batteries, only the ions are exchanged by sodium or magnesium ions. Sodium-ion batteries are infact already used, for example in electric bikes made by the company Faradion.
This video from Frankly Chemistry outlines the process in which molten lithium chloride is broken down into its elements using electricity - showing the oxidation of chloride ions to form chlorine gas molecules and the reduction of lithium ions to form molten lithium.
Physicist Jim Al-Khalili focuses his attention on the very strange nucleus from an isotope of Lithium that only exists due to the 'weird rules of quantum mechanics'.
Geography Case Study
Lithium is key to green technologies.
The “Lithium Triangle” of Argentina, Bolivia and Chile, holds most of the world’s lithium reserves.
Chinese businesses face allegations of the violation of the rights of local communities, damage to ecosystems and unsafe working conditions.
Argentinian lithium miners surrounded their Chinese managers’ compound and blockaded the entrance with flaming tyres.
This resource includes a variety of lesson activities to pick and choose:
Which Geography keyword is the ODD ONE OUT?
5Ws &1H about Tesla Motors and Elon Musk
5Ws &1H about a photo of lithium salt mounds
In which photo would you be most likely to … meet a worker whose health is at risk?
Critical Thinking: write THREE sentences to LINK these four images (technology: manufacturing, sales, use, waste)
Worksheet and data to construct a dot distribution map of China’s lithium mines around the World
PQE: China’s Lithium Mines - worksheet to analyse the dot distribution map using critical thinking (Patterns, Quantify, Exceptions)
Several slides for screen projection: encourages class evaluation of the positives vs negatives of dot distribution
Slide showing annotated map of Global North vs Global South - encourages analysis of correlation between lithium mining and socio-economic development
Link to video: “Argentina indigenous groups
protest against lithium mining”
Concept Map: The Lithium Triangle (35 snippets of info, to be colour-coded according to Locations, Causes, Effects, Management, Supporting Data)
The concept map info can then be used for:
Thought Chains: The Lithium Triangle - complete the scaffolding to complete six pieces of analysis…
“Chinese firms have been buying lithium mines in South America because…”
“The lithium mining industry in South America is SOCIALLY unsustainable because…”
“The lithium mining industry in South America is ECONOMICALLY unsustainable because…”
“The lithium mining industry in South America is ENVIRONMENTALLY unsustainable because…”
“Electric car makers buy Chinese lithium-ion batteries because…”
“Electric cars are not yet completely sustainable because…”
Geography Web: The Lithium Triangle
Pupils link feature and analyse the connections between the Lithium Triangle and China, Argentina’s government, indigenous people, Tesla Motors
TEACHERS’ BACKGROUND INFORMATION sheets (x3) with links to relevant articles and original BBC News story
This worksheet is intended for use during or after a teacher demonstrates (or shows a video) of the reaction of lithium, sodium and potassium with water.
This PowerPoint presentation with worked examples and student questions covers:
Flame tests for lithium, sodium, potassium, calcium, and copper.
Electron energy levels and emitting radiation.
Precipitate tests for iron(II)), iron(III), copper(II), calcium, and zinc.
Topics

• Oxidation
• Reduction
• Redox
• Oxidising agent
• Reducing agent
Knowing the approximate percentages by volume of the four most abundant gases in dry air
Knowing the conditions under which iron rusts
Understanding how the rusting of iron may be prevented by barrier methods, galvanizing and sacrificial protection
Understanding how to determine the percentage by volume of oxygen in air using experiments involving the reactions of metals (e.g. iron) and non-metals (e.g. phosphorus)
Understanding how metals can be arranged in a reactivity series based on their reactions with:
• Water
