COOPERATION BETWEEN PRAGUE AND PARENTIS

Monday: We were in Biscarrosse Beach all Day, and We learnt how to recognise many plants.

Tuesday: At. the morning we were in two museums in the afternoon. We went back again in our headquar-

ters in Biscarrosse

Wednesday: We were again in our headquarters.

Musée des traditions et de l’histoire de

Biscarrosse,

Tuesday June 1st

Today,in the morning, we went in a museum in Biscarrosse from 10:30 to 12:00.

At first, we saw a film. It was only in French, so the Czech didn’t understand. It ex-

plained how the area looked like before. After, we saw a map. There was a guide who talked

us about the map and the region. She explained the area was very flat and she was boggy.

So, the persons who lived in the Landes must planted up pin trees. After, we saw the room of

Monday In the morning we went by bus from Parentis to Biscarrosse beach. There we made groups (each

group had different job). Then we went by bike to the dunes. We learnt how to identify a lot of

plants. We were on the beach and we touched the Atlantic. Then we went back to the headquar-

ters. We had a picnic outside. Baguettes were delicious. Afterwards we received some forms for

our next job which was about recognising plants on the dune. Technically we were doing the

same work as we did before just in different groups. In the end we had some free time on the

beach and we draw some word in the sand. It was a good day.

Wednesday, the 2nd of june Some pupils were listening to music and at the same time they were working on the identifi-

cation sheet of the plants.

Before finishing their identification, the pupils went to the dune to take more pictures.

After that pupils did several activities. For example thank the people who allowed us to or-

ganize this echange. Another team created the cover of our brochure. Another student selec-

ted pictures taken during the week.

Everybody was hungry so we had lunch in the sun.

The report about the museum We had a meeting at 8:30 behind the school. We went by bus to the small city Sanguinet and our first acivity was visit the Museum of the laque. The guide told us many information about the Sanguinet lake. In the past, there was only a river, which was blocked by the dunes a long time ago. It took many years and the lake appeared. The dunes are up to 85 metres high and they were made by the west wind and sand from the Atlantic ocean. The exibithion continued and French teacher was translating the information to English. Then we could see some old coins, vase, bowls and things, which were used by old inhabitants. The long wooden boats were made from pine tree, they were under the water level, the scientists took them up and put them into the museum.

On Monday morning we made identification of the plants with Mr. LABAT. Many plants

were identificated. In the afternoon we went to the dune and we did the work, which our

teachers gave for us: find and describe 2 plants. We found these plants in the areas (each 10

metres, about diameter 4 metres). When we found something, we wrote it on worksheet. (we

had 5 categories - + single plant, 1. a few plants of the same species, 2. a lot of plants but

less 50% of the area, 3. this species cover more than 50% of the area, 4. this species cover

more than 75% of the area). Finally we shared the information with the other students.

The rules were not to step on the plants and respect the dune.

Ulex Europaeus is a plant which pricks and makes

yellow flowers.

This plant lives in the wood and normally not in the dune.

If we find this plant in the dune, it’s because ONF

takes branches and put them on the dune to fix it.

Some branches grew up on the dune.

Thanks

We want to say Thank you to the Biscarrosse mayor because he lent us tables and chairs and

a small house (la régie du Vivier) near the sea and welcomed us .

We also want to thank the ONF because they gave us some books and they gave us the au-

thorization to study the dune area.

We say thank you to the Comenius European Project. It’s very nice to meet foreign students

and work with them .

We also thank the teachers who are here because they’re very nice.
