Explanation
Changes in nature are called natural phenomena. Phenomena of non-living nature: rain, snow, hail, fog, dew, lightning, rainbow, wind. Phenomena of living nature: trees blossoming, leaves turning yellow and falling, birds flying to warm lands, a bear going into hibernation. The change of day and night happens every day. Tornadoes and tsunamis are rare.
Worked examples
In autumn leaves turn yellow and fall; in spring fruit trees blossom.
During a thunderstorm we stay indoors and do not stand in the open or under a tree.
Class activity
One-week observation: set aside a page for each day of the week. Each day record or draw the weather: sunny, cloudy, rain, wind, temperature (hot, warm, cool, cold). At the end of the week compare with classmates: which phenomena were the same for everyone? Safety: do not watch lightning from outdoors and do not stay long in the sun.
