Effects of water temperature

This section of Science Experiments deals with effects of water temperature change. The effects of water temperature science fair experiment is one of the very simple home science experiments.

Purpose of this science experiment

The purpose of this science experiment is to explore expansion of water.

What happens when water freezes? why does water expand when it freezes? why does water expand when frozen?

Does water expend or contract under different temperature? All these science experiments questions are often asked. Below is the science experiments that will show the effects of water temperature on water.

The concept of expansion and contraction of water and other metals

Many things (including water) expand or contract when they change temperature. Have you ever noticed, when standing by a railroad track, why there are gaps in the rails at certain intervals? The spaces in the rails allow them room to "grow," in case they expand; otherwise, the rails would buckle. Track
engineers know exactly how big the gaps should be to allow for this rail expansion.

If you have electric baseboard heat in your home, you may have heard the crackling sounds it makes when the metal fins heat up or cool down. That's because the fins are expanding and contracting. Gaps in the roadway of bridges are also there to allow for expansion and contraction from temperature changes.

Equipment you will need for this science fair experiment

In this effects of water temperature science experiment, you need

• empty metal soup can
• water
• use of a freezer
• small bowl
