實(shí)驗(yàn)?zāi)康模?br />觀察研究燈光變化對(duì)物體表面色彩的影響。
實(shí)驗(yàn)器材：
變色龍儀器。
實(shí)驗(yàn)過程：
1、將電源線插頭插入電源插座。
2、從儀器上面的窗口，仔細(xì)觀察內(nèi)部圖片色彩。
3、按住開關(guān)燈亮后，仔細(xì)觀察內(nèi)部圖片色彩的變化。
探究問題：
1、借助自然光來仔細(xì)觀察儀器內(nèi)部圖片色彩，顏色豐富多彩。
2、按住開關(guān)，紅色的電燈亮后，儀器內(nèi)部圖片色彩的色彩為什么變化很大？
3、紅燈亮后，綠色的龍，看上去幾乎變成了黑色？
4、如果換成綠燈或藍(lán)燈，會(huì)出現(xiàn)怎樣的現(xiàn)象呢？

（以下由學(xué)生總結(jié)并交流，也可由教師引導(dǎo)得出。）
注意事項(xiàng)：
實(shí)驗(yàn)完成后，應(yīng)及時(shí)拔下電源插頭。
Chameleon
Experimental purpose:
Observing and researching the influence on the color for the surface of the objects when the light changes
Experimental equipment
The chameleon instrument
Experimental process:
1. Plug into the electrical outlet.
2. Observe the colors of the pictures in the instrument from the upper window.
3. Turn on the switch, and observe the changes about the colors of the inner pictures when there appears the lamplight.
Researching issues:
1. Use the natural light to observe the colors of the pictures in the instrument carefully.
2. Why do the colors of the inner pictures change so large after turning on the red light?
3. Why does the red light become black after turning the red light?
4. What happened if you turn on the blue light or the green light?
Experimental conclusions and the experience:
The followings can be concluded and discussed by the students, or guided to get by the teachers.
Caution:
Cut off the power supply on time after the experiment.
