The City f Science and Industry ,a museum in Paris
Listen t the tape and discuss the fllwing questins in grups.
I wuld like t g t this museum t see ... I am curius t knw can see my bld cells ... I am sure it will be ...
What I like mst is that I can reasn why I wuld like t g t this museum is that it is..
1. Wuld yu like t g t this museum?Why r why nt? What can yu d in the City f Science and Industry? What d yu like mst abut it?
Answer the fllwing questins.
What can yu d in the City f Science and Industry?
I wuld like t g t this museum t see the blue screen. I am curius t knw what n earth is ging n there and why I can see my bld cells mving arund like tiny bright lights. I am sure it will be a lt f fun.
What d yu like mst abut it?
The reasn why I wuld like t g t this museum is that it is an amazing place fbr us t have fun, learn, and get inspired. Just as the pictures shw, there is a lt f interesting stuff t d there.
What I like mst is that I can participate in the interactive activities and explre the scientific phenmena fr myself.
Yu can discuss like these:Have yu ever been t such a museum in China?Where is it?What is it like?What did yu d there?What ther interesting museums did yu visit?
2. Are there any museumes like this in China? What ther interesting museums are there?
Yes. There is the China Science and Technlgy Museum in Beijing. It's very grand and mysterius. I went t explre the theries f science.I als have visited the Shanghai Science and Technlgy Museum.

Discussin and presentatin.
Reading material:
Tday, I want t talk t yu abut a very strange phenmenn called a nn-Newtnian fluid. Yu can make it easily using equal parts f water and crnflur, like I have here. A nn-Newtnian fluid is strange because yu can pur it like a liquid but if yu put any pressure n it, it suddenly becmes hard as cncrete. In fact, it becmes hard enugh t stand n. Then, as sn as yu take the pressure ff, it becmes a liquid again. This shws that it is pssible that smething can exist as a liquid and a slid at the same time.
What infrmatin des the example give ut abut the scientific phenmenn ?

Presentatin
The scientific phenmenn is called a nn-Newtnian fluid.It can exist in the frm f a slid and a liquid. What is strange is that if yu put any pressure n it, it suddenly becmes hard as cncrete. If yu take the pressure ff, it will becme a liquid again. That demnstrates that smething can exist as a liquid and a slid at the same time.

Talking abut scientific phenmenn
Tday, I want t talk t yu abut the psitive and negative charges f mlecules. We can demnstrate hw these interact thrugh a simple experiment using milk, dish sap, and fd cluring. First, cver the bttm f a shallw plate with milk. Nw add tw r three drps f different liquid fd cluring t the centre f the milk. They shuld frm ne large dark puddle in the middle f the milk. Nw, dip a cttn swab int dish sap, and place it int the middle f the fd cluring.
Yu will see the clurs quickly mve t escape frm the sap, making interesting and beautiful patterns. This happens because the dish sap mlecules have a strng negative charge, and the milk mlecules have a strng psitive charge. Like magnets, these mlecules are attracted t each ther, and s they appear t mve arund n the plate, taking the fd cluring with them, making it lk like the clurs are quickly mving t escape frm the sap.
The scientific experiment is called interact between the psitive and negative charges.Milk, dish sap, and fd cluring are what the experiment needs. If yu add tw r three drps f different liquid fd cluring t the milk,they shuld frm ne large dark puddle.But after yu d s ,yu will see the clurs quickly mve t escape frm the sap. That is because the dish sap mlecules have a strng negative charge, and the milk mlecules have a strng psitive charge. They attract each ther, and s they mve arund n the plate, taking the fd cluring with them,just like the clurs are escaping frm the sap.
Put the fllwing sentences int English

that if yu put any pressure n it, it suddenly becmes hard as cncrete.
