What should we do if we encounter lightning weather outdoors in the first volume of fourth grade science?

When encountering thunder and lightning outdoors: Do not take shelter under trees or telephone poles. You should stay in dry and low-lying places; keep distance from others and do not crowd together; avoid riding bicycles; Make and receive calls on mobile phones, etc.

If you encounter a thunderstorm outdoors and it is too late to leave the tall object, you should immediately find some dry insulation and place it on the ground, and sit on it with your feet together. Do not place your feet on anything other than the insulation. On the ground, because water conducts electricity. When sheltering from a thunderstorm outdoors, you should be careful not to support the ground with your hands. At the same time, you should hug your knees with your hands, keep your chest close to your knees, and lower your head as much as possible, because the head is most vulnerable to lightning strikes than other parts of the body.
