Room 1: Microscale NLC Workshop 2022 by AST https://padlet.com/moe_stp1_1/n1tewq0j2wtkimvk The wonder of microscale en-us 2022-04-05 06:53:18 UTC 2025-04-24 08:59:44 UTC hello@padlet.com Activity 1: Reactivity of Metals moe_stp1_1 https://padlet.com/moe_stp1_1/n1tewq0j2wtkimvk/wish/2130126037 - Prepare HCl with half the concentration, add Mg. Based on the extent of effervescence, student deduce the concentration of the acid used. [Concept of acid concentration can be taught]. ]]> 2022-04-05 06:53:18 UTC https://padlet.com/moe_stp1_1/n1tewq0j2wtkimvk/wish/2130126037 Activity 2: QA moe_stp1_1 https://padlet.com/moe_stp1_1/n1tewq0j2wtkimvk/wish/2130126038 design an escape room with qa lab tasks

-Accumulation of carbon dioxide, simulating “rockets” can be fun  especially when using warm acids
-Catalyst experiment, using soap
-Use Vit C, Alka-Seltzer tablets instead of CaCO3

1   investigate the chemical properties of steel using the POE approach;
2   understand how the chemical resistance of iron can be improved when it is made into an alloy.]]> 2022-04-05 06:53:18 UTC https://padlet.com/moe_stp1_1/n1tewq0j2wtkimvk/wish/2130126050 Activity 2: QA moe_stp1_1 https://padlet.com/moe_stp1_1/n1tewq0j2wtkimvk/wish/2130126051 We can use predict, observe, explain thinking routine to allow students to enhance student's understanding]]> 2022-04-05 06:53:18 UTC https://padlet.com/moe_stp1_1/n1tewq0j2wtkimvk/wish/2130126051 Activity 3: Speed of reaction-Teaching Actions moe_stp1_1 https://padlet.com/moe_stp1_1/n1tewq0j2wtkimvk/wish/2130126054 1. Inquiry Based Learning - the lesson can be structured to allow students to conduct the experiments to discover the changes to rate of reaction and lead the class to Concentration and Collision Theory.
2. Predict-Observer-Explain - the lesson can a follow up after Collision Theory is first explained.
3. Collaboration - students can work in pairs. Class results can be consolidated as results analysed as a class.

For example, students could take photos and upload photos and make their own summary of colour of different salt precipitates.]]> 2022-04-07 08:36:10 UTC https://padlet.com/moe_stp1_1/n1tewq0j2wtkimvk/wish/2134214358
