Let’s Use Our Hands to make a Chemical Mixture Homemade play dough is a great science experiment for young learners. But, more than learning about chemistry, this play dough activity connects to other curriculum, including math and art. But one of the best parts is that it is FUN! Even adults will want to get […]
How Energy Affects States of Matter
What Happens When A Substance Gains or Loses Energy? For this article, heat will be the energy source and water molecules the substance gaining or losing energy. So, what happens when water molecules gain or lose energy? Energy is needed for motion, the more energy a substance has the faster is its motion. The reverse […]
The Melting and Freezing of Water
How Can Water Freeze and Melt at the Same Temperature? The freezing/melting point of water is OºC. But it is not an instantaneous physical change. Instead, both liquid water and ice can be present at OºC. At this temperature, there is a constant exchange of water molecules between the ice and liquid water as shown […]
States of Matter: Solid
Matter exists naturally in four states. These states in order of energy from least energy to greatest energy are: Solid Liquid Gas Plasma A SOLID is the state of mater with the least amount of energy and the most structure. Solids exits in two basic forms: 1. Crystalline solids are those in which the particles […]
Gases Have Volume
Chemistry is the study of the composition, structure, properties, and interactions of matter. Matter is all the material in the universe. Simply, matter is the stuff that things are made up of. Matter has mass and volume. Mass is the amount of material (stuff) something is made of. Mass is not affected by gravity. Materials are […]
