FIRE RESISTANT BALLOON: Materials - 1 matchbox - 1 candle - 1 yellow colored balloon - 1 blue colored balloon - Half a cup of water Procedure: 1. For this experiment‚ the independent variable is whether the balloon is filled with water or not. The dependent variable is what happens to the balloon when it is placed above the lit candle. This is determined by observing the balloon. The constants (control variables) are how much the balloon is inflated and the amount

The customary age of production and the age of mastery are both similar and different in their own ways. First‚ let us define them and work from that starting point. The customary age of production is “the age by which 50% of all children can produce a given sound in multiple positions in words in an adultlike way.” The age of mastery is “the age by which most children produce a sound in an adultlike manner.” These terms are similar in that they both focus on when the child can produce adultlike

6. Applications * Is it possible to add heat to a body without changing its temperature? Yes. It is possible to add energy to a body (in the form of heat) and not raise its temperature by causing a phase change. When you heat ice it takes energy to convert it from ice to water‚ but does not change the temperature of the body until it is all converted. The principle behind this is what we call latent heat. It refers to the energy (or heat) required to change the state of a substance without changing
