 * Compare Events - Compare and contrast events that demonstrate evaporation, crystallization, and melting
 * Compare Events - Compare and contrast events that demonstrate evaporation, crystallization, and melting

|| # [|Changing State] - [ designed for 4-5 UK standards ] Use this interactive site from the BBC to investigate what causes water to change state. Take a quiz when you have finished.
 * 1) [|Matter in the Science Lab] - Select **Matter** in the list of labs. The illustration names the physical state of objects. Next, click on **Water Changes State** near the top of the matter window. Hold down the blue button to lower the temperature of water to freezing, then hold down the red button till water boils. Click on the **book** in the bottom left corner to read about matter.
 * 2) [|Solids and Liquids] - [ designed for 3-4 UK standards ] Investigate the effect of heat on a variety of objects, then take a quiz. ||
 * Change Physical Properties - Make predictions and conduct experiments about conditions needed to change the physical properties of particular substances

|| # [|Boil Water With Shockwave] - Run this experiment, changing the water amount, the starting water temperature, and the heating power. Enter how long you think it will take to boil the water [ bring the water to 100°C ]. The accuracy of your guess, as a percentage of the actual time, will be displayed.
 * 1) [|Keep-a-Cube] - Using materials listed, make a container to see how long you can keep an ice cube from melting. Find out what works best to keep the heat away from the ice cube.
 * 2) [|Solar Cooker] - harness the sun's energy to make a tasty treat (s'mores) - the experiment procedure includes instructions on how to include a control (also s'mores) - good science and tasty fun ||
 * Combinations - Classify combinations of materials according to whether they have retained or lost their individual properties

|| # [|Classification of Matter] - Answer a series of questions to determine if a substance is a mixture or compound. evaporation, settling, or using a sieve
 * 1) [|Mixtures and Compounds] - a short movie featuring iron and sulphur illustrating the difference between a mixture and a compound ||
 * Separate Mixtures - Investigate different ways to separate mixtures such as filtration,

|| # [|Impure Substances: Mixtures] - definition and examples ||
 * 1) [|Separate a Mixture of Ammonia and Sand] - animation and explanation
 * 2) [|Separate a Mixture of Sand and Water] - animation and explanation
 * 3) [|Separate a Mixture of Water and Sulphur] - animation and explanation
 * 4) [|Separate Salt from a Salt Solution] - animation and explanation
 * 5) [|Separating Mixtures] - four types of Quia quizzes on this topic
 * 6) [|Separating Mixtures] - several examples are given ||
 * Physical Properties - Describe a substance in terms of its physical properties
