## 課堂引導

### Warm-up 
1. Review what engineers do (5 steps of the design process) (2min) 
2. Review Emma’s problem (0.5min) 
 

### Step 2-Plan and Build

1. Play the video on page 8 (1 min) 
2. Discuss what Emma does: (5 min) 
 - draws a model 
 - builds her model 
Think: why we need to make a plan? why build a model first instead of doing it immediately? 
(A model shows what an object or tool looks like and how it works. ) 
3. Play the video “Build a Better Lunchbox” (這里應該要做一個小實驗；時間所限就不做了，改為帶娃觀察他自己的午餐包是如何設(shè)計的) （2min） 
4. Review the problem we defined in last lesson (1min) 
 

5. Plan and Build a solution (10 min), record in EN.

### Step 3-Test and Improve 
1. Play the video on page 11 (1min) 
2. Discuss: how do you think of the design solution Emma came up with? Do you think it will work? Why the first solution does not work? (The ramp needs to be a solid surface) (5 min)
