This has two aspects. One is descriptions of current technologies. The other is a chance for students to predict the impact of each technology on life in the 21st Century.

As I see it, the descriptions could come from either adults or children but it would be better if the predictions all came from students younger than 18. (Their thinking may need to be guided by adults however.) It would be good to have many different predictions about each technology.

Our goal is to learn from the "past" for the "future".

I would like to encourage our 6th grade students:

Continuation of Earth Calendar Online Holidays and Festivals Project. 
Children and their teachers or families use drawings or photographs to display the way people celebrate the days that are special in their part of the world.

Children publish information about what is done in their country to mark the Year 2000 - it might be a special coin that is minted, or a new postage stamp, or a new recipe, or a sculpture.

What conservation methods were introduced in your region during the 20th Century? What wildlife was important to preserve and has this changed over the course of the century?

Please tell us about current conservation in your country. What methods are used to help preserve your natural environment and wildlife?

What would you like to see preserved for your children and their children to enjoy? Can you think of the ways in which this could be achieved?

Migration during the 20th Century
During these years millions of people moved from country areas to cities, from one town to another or from one country to another, even moving to the other side of our planet.
Children interview their parents and grandparents and tell stories about moving, why families moved and what happened during the move, how they settled in the new place, using photos and drawings.

Continuation of Earth Calendar Online Exploring the Street Project.
Children or their teachers photograph items of interest in the street near where they live, items such as postboxes, garbage bins, police cars and these are compared with those from other countries.

What happened in a street near you on January 1, 2000?
People take photos and we compare - maybe we will see the difference between Northern and Southern Hemisphere seasons.

I would like to encourage students to record the present school life and to compare it with that of students in the world. Please send photos, drawings, videos of your school life with short text.

Children ask their parents and grandparents about the toys of the past. 

Aim: By comparing tools which have been dramatically changed that grandparents used and children/parents are using now, I would like children to realize the progress of technology.

Children take a photo of a tool which their grandparents or old people used. Then they ask viewers "Guess what". 
Other children answer "what it was (is) for" with text or drawings. 

Children think about the work people did in the past that is entered in project p05 Tools our grandparents used and show what they (or their parents) are using now for the same purpose, which might not differ so much in the world.

Taking the tasks identified in projects p05 Tools in the Past and c08 Tools used now, design a future tool that will be good for this sort of work. Tools might be for calculation, washing, cutting grass, taking a bath, keeping warm, etc.

Children choose a well known fairy tale e.g. a story by Hans Christian Anderson or the Grimms brothers and see if they can rewrite it to happen in the year 2000.
