Part 1--Using LanguageTalk abut scientific experience
Lk at the phts and discuss the questins:
1. What are the peple ding in each pht?
2. What d these activities have t d with science?
1.What are the peple ding in each pht?
In pht A, a by is speaking int a giant dish.In Pht B, a girl is jumping n a giant pian keybard. In Pht C, a by is lking at a blue screen. In Pht D, a girl is standing in frnt f a hall f mirrrs where she can see herself reflected thusands f times. In pht E, a by is standing in frnt f a white light.
2.What d these activities have t d with science?
A: I think the dish in this exhibitin is related t sund. Maybe the by is whispering int the smaller circle and the dish can make his vice luder.B:This lks like a pian yu play with yur feet.Maybe it shws hw sund wrks.C: I’m nt sure what this ne shws,but it must be abut light r eyesight.D：It is a hall f mirrrs.Maybe it has t d with principles f reflectin.E:This is prbably an experiment invlving the cmpsitin f light.
Pre-listening
The phts abve are related t the cnversatin yu will hear. Based n the phts abve, predict the answers t the fllwing questins:
a) Where are the peple in the cnversatin ging t g?b) What kind f place is it, and what des it fcus n?c) What kinds f things can yu d there?
Predict by using picturesne way t get mre ut f yur listening is t predict what yu will hear. Using the pictures prvided and the knwledge yu already have, yu can guess the kinds f infrmatin yu shuld listen fr. At times, yu may even be able t guess exactly what will be talked abut.

1.Where are the peple in the cnversatin ging t g?2.What kind f place is it, and what des it fcus n?3.What knids f things can yu d there?
They are ging t a science museum.
It is a science museum that fcuses n letting visitrs experience science thrugh interactive learning exhibitins.
I can prbably try different activities t learn abut sund, light, reflectin, and s n. Fr example, I can g t a rm with many mirrrs facing each ther s it lks like there are many cpies f me! Or I can play with a big pian n the flr.
While-listening
Listen t the cnversatin and write dwn the letters (A-E) fr the phts in the rder that yu hear them described.
