Room 2: Microscale NLC Workshop 2022 by AST https://padlet.com/moe_stp1_1/xddpnuuur7kwh9px The wonder of microscale en-us 2022-04-05 06:57:10 UTC 2025-09-24 02:02:15 UTC hello@padlet.com Q1: How can you adapt/modify the experiment to teach other concepts which your students might have difficulties with? mr_andrew https://padlet.com/moe_stp1_1/xddpnuuur7kwh9px/wish/2133884296 Example:
- 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].   ]]> 2022-04-07 03:44:46 UTC https://padlet.com/moe_stp1_1/xddpnuuur7kwh9px/wish/2133884296 Q1: How can you adapt/modify the experiment to teach other concepts which your students might have difficulties with? mr_andrew https://padlet.com/moe_stp1_1/xddpnuuur7kwh9px/wish/2133886092 Example:
- design an escape room with QA lab tasks]]> 2022-04-07 03:46:36 UTC https://padlet.com/moe_stp1_1/xddpnuuur7kwh9px/wish/2133886092 Q1: How can you adapt/modify the experiment to teach other concepts which your students might have difficulties with? mr_andrew https://padlet.com/moe_stp1_1/xddpnuuur7kwh9px/wish/2133887460 Example:
- Iodine clock is very very quick for effect of concentration on SOR but there are a lot of chemicals to prepare
- 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

Inquiry-based learning where students work in pairs to 
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.]]> 2022-04-07 03:49:28 UTC https://padlet.com/moe_stp1_1/xddpnuuur7kwh9px/wish/2133888754 Q2: What teaching actions can be incorporated into the adapted/modified experiment? mr_andrew https://padlet.com/moe_stp1_1/xddpnuuur7kwh9px/wish/2133889629 Example:
- We can use predict, observe, explain thinking routine to allow students to enhance student's understanding]]> 2022-04-07 03:50:19 UTC https://padlet.com/moe_stp1_1/xddpnuuur7kwh9px/wish/2133889629 Q2: What teaching actions can be incorporated into the adapted/modified experiment? mr_andrew https://padlet.com/moe_stp1_1/xddpnuuur7kwh9px/wish/2133890881 Example:
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.]]> 2022-04-07 03:51:38 UTC https://padlet.com/moe_stp1_1/xddpnuuur7kwh9px/wish/2133890881 Concept on strong & weak acids by reacting magnesium with strong and weak acids. https://padlet.com/moe_stp1_1/xddpnuuur7kwh9px/wish/2134200452 2022-04-07 08:25:06 UTC https://padlet.com/moe_stp1_1/xddpnuuur7kwh9px/wish/2134200452 Link reactivity to volume of hydrogen gas produced https://padlet.com/moe_stp1_1/xddpnuuur7kwh9px/wish/2134201106 Students will be able to see the extent of effervescence & relate to the volume of H2
