Under pressure from animal welfare groups, two national science teachers associations have adopted guidelines that ban classroom experiments harming animals. The National Association of Biology Teachers and the National Science Teachers Association hope to end animal abuse in elementary and secondary schools and, in turn, discourage students from mishandling animals in home experiments and science fair projects.
Animal welfare groups are apparently most concerned with high school students experimenting with animals in extracurricular projects. Barbara Orlans, President of the Scientists' Center for Animal Welfare, said that students have been performing surgery at random, testing known poisonous substances, and running other pathology experiments on animals without even knowing normal physiology.
At one science fair, a student cut off the leg and tail of a lizard to demonstrate that only the tail can regenerate, she said. In another case, a student bound sparrows, starved them and observed their behavior.
"The amount of abuse has been quite horrifying", Orlans said.
Administrators of major science fairs are short-tempered over the teachers' policy change and the impression it has created. "The teachers were sold a bill of goods by Barbara Orlans", said Thurman Grafton, who heads the rules committee for the International Science and Engineering Fair. "Backyard tabletop surgery is just nonsense. The new policies throw cold water on students' inquisitiveness", he said.
Grafton said he wouldn't deny that there hasn't been animal abuse among projects at the international fair, but he added that judges reject contestants who have unnecessarily injured animals. The judges have a hard time monitoring local and regional fairs that may or may not choose to comply with the international fair's rules that stress proper care of animals, Grafton said.
He said that several years ago, the Westinghouse Science Talent Search banned harmful experiments to animals when sponsors threatened to cancel their support after animal welfare groups lobbied for change.
The teachers adopted the new policies also to fend off proposed legislation—in states including Missouri and New York—that would restrict or prohibit experiments on animals.
Officials of the two teachers organizations say that they don't know how many animals have been abused in the classroom. On the one hand, many biology teachers are not trained in the proper care of animals, said Wayne Moyer, executive director of the biology teachers' association. On the other, the use of animals in experiments has dropped in recent years because of school budget cuts. The association may set up seminars to teach better animal care to its members.

Rodney Mace, 35, is married with two young children, and is a part-time teacher of architectural history. "I am constantly surprised by other people's surprise, when they come to the house and see me cleaning a floor or hanging out the washing. Their eyes open wide at the sight of it! Much of the comment comes from men, but I am even more surprised at the number of women who comment too."
His wife Jane, an Oxford graduate in modern languages, has a demanding full-time job. She is director of the Cambridge House literacy scheme for adults in South London. Her working week involves several evenings and Saturdays, and at these times her husband is in sole charge of home and family. Apart from this, they share household jobs and employ a child-minder for the afternoons. This enables him to teach two days a week and to do what he considers is his principal work: writing. He has written several books and spends much of his time in the British Museum Reading Room, cycling there from his home in Brixton.
People ask the Maces if they think that their children miss them. One can argue that satisfied parents generally have satisfied children, but in any case the Maces are careful to reserve time and energy to play with their children. "And they have now developed relationships with other adults and children."
Previously, Rodney Mace worked full - time and Jane only part-time. Then 18 months ago, the director of the literacy scheme left. "It seemed to me that Jane was very' well suited to do this job. She was very doubtful about it. But I urged her to apply. She did, and she got it." Jane Mace confirms that she needed this encouragement, as so many women initially do.
Did his male ego suffer from the changeover? Nothing like that occurred. But he still seems amazed at the way it changed his thinking. "I felt that we were finally going to be partners. I felt enormous relief. I wasn't avoiding responsibility, but changing it. Our relationship is so much better now. It has been a change for the good for both of us——I think for all of us, in every aspect of our lives. I cannot overemphasize that in every aspect. I think it is fundamental that the woman works. The idea of equal partnership is an illusion if one partner doesn’t work."

A.they have a truly equal partnership
B.the husband enjoys staying at home
C.they earn more money
D.the wife has a full-time job
