Thank you for your contributions to the Discussion Forum and for e-mails with pictures and results. It is wonderful to see how fast your trees are waking up and turning green.
In TASK 3 – First Leaves we will measure and record the length of new leaves. To record the change, it is important to visit your tree at least twice a week.
The activity should be completed by May 15th.
To earn a Collaboration badge, share the picture of your tree with leaves.
Activity 3 – First Leaves
1) Keep observing the branch you selected
- Once you see a bud opening (= you can see the tip of green leaf), record “budburst” to your data sheet
- All 4 buds may not open at the same time
2) Measure the length of a leaf that grows from the bud
- measure and record the length at least twice a week
- use a simple ruler to measure the length in mm
- measure the leaf without the stem
- continue measuring the leaf until it stops growing
3) Take pictures regularly
- Share the photos here at Discussion forum.
- If you participate in the Collaboration group, don´t forget to compare your results with your partner school.
4) Optional: Record temperature and precipitation
If you have an Atmosphere site nearby, keep recording temperature and precipitation data along with observing the leaves and see if there is any link.
And do not forget to continue taking pictures of your tree using GrowApp
