Why Do Puddles Dry Up?

Subject Area

Science

Grade(s)

K

Overview

Students will be able to explain that puddles dry up because tiny particles of water (water molecules) break away from the puddle and go into the air. Students will be able to explain that the water from the puddle that went into the air can become part of a cloud and come back down as rain and make a new puddle. This process is known as the water cycle. Students watch a video of a puddle drying up and have a class discussion about where they think the water goes when it seems to disappear. Students investigate a one-drop “puddle” in the palm of their hand. Students see an animation of water evaporating from a puddle and forming water droplets in a cloud. Students then compare a water drop evaporating from the palm of their hand to one evaporating from the surface of a desk or table.

    SC15.K.7

    Observe and describe the effects of sunlight on Earth’s surface (e.g., heat from the sun causing evaporation of water or increased temperature of soil, rocks, sand, and water).

    Knowledge

    Students know:
    • Sunlight warms the Earth's surface.
    • Know different patterns of relative warmth of materials in sunlight and in shade (e.g., hotter, warmer, cooler, and colder)
    • Materials on the Earth's surface can be investigated (e.g., dirt, sand, water) and described.

    Skills

    Students are able to:
    • Investigate the effects of sunlight on Earth's surface.
    • Observe the effects of sunlight on Earth's surface.
    • Describe the effects of sunlight on Earth's surface.

    Understanding

    Students understand that:
    • Sunlight causes an observable effect on the Earth's surfaces including: water, soil, rocks, sand, grass.
