Reaction of Metal and Acid (How Size of Mg affects Vol of H2) Quality Mark Assessment (TASK ONLY)

This is the free version of an assessment for KS3, or low level KS4 students who are studying chemical reactions, specifically the reaction between metals and acids, this assessment investigates the link between the size of magnesium added to an acid and the volume of hydrogen gas produced.

I have also produced a resource pack available to purchase from TES at
https://www.tes.com/teaching-resource/model-cells-quality-mark-assessment-full-resource-pack-11350637

The resource pack comes with several parts;
1. PowerPoint presentation to introduce the task.

2. Word document printout for the students to stick in their books with just the task on, there is also a word document with both the task and level ladder combined onto one sheet to reduce printing.

3. Word document printout with a level ladder on so that the students can self/peer assess the work, there is also a column so the teacher can tick off the achieved criteria.

4. Word document containing a mark scheme.

5. Excel spreadsheet that can be used to automatically generate extended written feedback including improvement strategies for the teacher to give the students.

6. Word document printout writing frame to assist students who may benefit from additional help with this task.

7. JPEG images showing a several hand-drawn versions of the graph, this may also be useful for students who aren't confident in starting to plot graphs. I've included sketches of the extrapolation of the data from the line of best fit, and highlighted the anomalous result.

This involves the students plotting some given results on a graph, identifying variables, extrapolation from a line of best fit and evaluating their work.

This task is suitable for KS3 students at level 3-7, however this could be adapted for KS4 students.
