ACTIVITY 1

MY TREE

This autumn we started measuring the colour change of the lime tree.

The lime tree aslo grows right next to the school. 

We start to observe the lime tree mainly because we found new friends from Olomouc who measure lime as well. We share the data together and at the end of the observation we want to compare the data for both trees.

- the LATIN NAME of the LIME is:

A1_My Tree_2023.pdf

A1_Muj strom_2023.pdf

In the first activity, we chose a tree to observe.

We continue to observe the birch tree that we have at the school campus.

- the LATIN NAME of the birch is:

COLOR CHANGE OF LEAVES

- we chose one branch that was low enough and marked it with a ribbon - we also selected 4 leaves that we will observe - we used colored strings to mark the individual leaves

4th October Mari + Neli are measuring the colour of the leaves .....

We used the GLOBE COLOUR SCALE to determine the dominant colour for each leaf ....

MY TREE

We already measured the geographical coordinates and altitude last year. We used COMPAS mobile application and determined the cardinal points.

Latitude: 49.100537 Longitude: 17.754018&nbsp;

this is the lime tree we measure ...

here we have recorded data about the location of our school and basic data about the tree

Jak vidíme ze záznamových archů, lípě v Olomouci opadl první list už 3. 11. 8. 11. opadl další list. 15. 11. opadly už tři a 20.11. všechny pozorované listy opadly. V Luhačovicích se všechny listy držely dlouho na větvičkách a až 25. 11. opadly najednou 3 listy. 27.11. opadly listy všechny. Tak jako u břízy vidíme, že stromy v Luhačovcích opadají zhruba o týden později než v Olomouci.

As we can see from the record sheets, the first leaf in Olomouc fell already on November 3rd, and the next leaf fell on November 8th. On 15th November already three and 20th November all observed leaves have fallen. In Luhačovice, all the leaves stayed on the twigs for a long time and it wasn't until 25th November that 3 leaves fell at once. 27th November all the leaves have fallen. As with the birch, we see that the leaves in Luhačovice fell about a week later than in Olomouc.

BIRCH

In Globe Visualization, we created a graph of the color change of our birch

we compared this year's data with last year's graph

all 4 leaves fell down

In Globe Visualization, we created a graph of the color change of our lime tree

Here is a comparison of leaf color change data from fall 2022 and this year. Last year, we started the observation on 9/22 and on 10/25 there were still 2 leaves on the twig, and on 3/10 all the leaves had fallen. This year it was a very warm autumn, we started observation on October 3, and on 10/31 there were still 3 leaves on the twig compared to last year. All the leaves didn't fall until 9/11. So this year's leaf fall was delayed by more than a week compared to last year.

SILVER BIRCH

White birch, also warty birch, is a deciduous tree from the birch family.

Male dogwoods are overhanging, they are about 4-7 cm long, they appear in April to June.

The fruits are about 2 mm in size and they are very light.

Fruiting begins at the age of 10 to 15 years.

It grows as a sturdy tree in the lowlands, but also as a dwarf tree high in the mountains or in the north in a cold climate.

We measured the geographical coordinates and altitude like for the birch. 

Latitude: 49006'00'' N Longitude: 17045'12'' E

we observed the trees twice or three times a week
