QUESTION: Dear Marie,

Do you have some good suggestions of biology: plant, animal, human science experiments that would work well with teenagers? Scientific methods must go with the experiments. Thanks! <

                                                           Donna

ANSWER: Dear Donna,

Marie is not online and I’ll help you instead of him. There are a lot of little things that can be done, but do you mean lab experiment or statistical analysis, etc.? Let us know what can be suitable for you teens, and we will do our best to send you some experiments to do.

                                                           Best,

                                                           Gloria

QUESTION: Dear Gloria,

I need lab experiments. The teenage students and I will use data from these experiments to make charts, graphs, tables, etc. and to provide claims and evidence to explain more about the results. Thank you very much.

                                                            Donna

ANSWER:

Hi there,

Your best and easiest way is to do some chemistry experiments. Those are very easy and most probably you can do it in the lab and have charts, etc. for you. I do not have any particular one at the top of my head because I do cancer research and it is a bit more difficult than research for teenagers. I think you can look through these and see if you find something useful for you. http://www.siraze.net/chemistry/sezennur/experiments.htm

If not, get back to me and Marie, and we’ll look more. The good thing about this site is that it has the procedures that you can follow.

                                                            Good luck,

                                                             Gloria

Crossroads International
How does Crossroads work?
Crossroads is a resource network. We take goods Hong Kong doesn’t want and give them to people who badly need them. We collect those goods and give them out in the welfare arena(福利院) in Hong Kong, Mainland China, elsewhere in Asia, Eastern Europe and Africa. So Crossroads is just that: a Crossroads between need and resource.
Who do we help?
The welfare agencies we help do not run on large budgets(预算). They are grass-root groups who have seen a need and tried to meet it. They can’t get the job done without back-up, though, so our task is to help them do their task. Our warehouse is full of goods, from computers to high chairs, clothing to books, stationery(文具) to medical provision, cupboards to dinning sets. They send us a list of their needs and we try to match it with the resource we have in stock.
How do we operate?
Crossroads itself also operates on a low budget. We do not buy the goods we send. They are donated. Similarly, rather than raising funds for freight(货运),we ask transport companies to donate their services. Nobody in our organization receives a salary. Even our full-time staff works on a voluntary basis.
Those that donate goods and services:
·Factories·Manufacturers ·Hospitals ·Hotels ·Householders
·Offices ·Other Charities ·Transport Companies ·Educational Institutions
One resource that we are always in need of is people. While we receive large quantities of goods and there is never a short supply of requests for them, we are always in need of hands to help sort and prepare them for shipping.
What can I do?
We are always in need of people. We have a lot of tasks. If you are volunteering regularly, we can offer work in some of the following categories, some of the time. You are welcome to number your top three choices and we will do our best to accommodate them.
·Clothing categorization ·Sewing ·Toy categorization ·Furniture handling
·Driving ·Book categorization ·Household goods categorization ·Office work
·Electrical goods categorization ·Book keeping ·Fund- raising
·Stationery categorization ·Medical categorization
Where to find us?
All volunteer work is done at out warehouse:
Located in Basement Zone M of the Kai Tak Government Building
Our warehouse hours: Tues.-Sat. 10:00am-5:30pm
Postal address: 16 Man Tong, Silvermine Bay, Lantau Island, HK
Office details: Ph: 2984 9309, 2740 9657
