KS3 ~ Year 8 ~ Metal & Water Reactions

This lesson is designed for the KS3 Year 8 Science course, specifically the C2 1.2 unit on ‘Metals & Other Materials’.

For more lessons designed for KS3 and KS4 please visit my shop at: https://www.tes.com/teaching-resources/shop/SWiftScience.

The lesson begins with a demonstration, students will be shown a demo whereby alkali metals are dropped in water one at a time, students need to note down their observations in a table. Once this is complete, students will be asked to predict what happens when francium and caesium are dropped in water, students will then watch a video to check whether their answer is correct.

Students will now be shown the general word equation for a metal + water, students will now be asked to copy and complete a set of further metal + water word equations. This task can then be assessed using the mark scheme provided.

Next, students will be given a set of statements and a number of grouped metals, knowing what they do about the reactivity of these metals with oxygen and with acid (from previous lessons) students will be asked to match the groups of metals to the correct statements - describing their relative reactivity. Once this task has been completed, students can self-assess their work using the mark scheme provided. Following this, students will need to use the statements provided to describe the way in which these metals react with dilute acid, once this task is complete students can self-assess their work.

Students will now be shown the word equation for the reaction of metal with steam, including the balanced symbol equation, with state symbols. Students will be asked to then write out the balanced symbol equation for zinc + steam, the answer to this will be provided so students can mark their work.

Lastly, students are given a set of sentence starters (metals) and they will need to match these to the correct sentence enders (description of the metal). This work can be marked and corrected using the mark scheme provided.

The plenary task requires students to write down three facts, three key words and one question to test their peers knowledge of what was learned this lesson.
