** Dream Believe Inspire ** abc **Science** **Week Beginning:** Monday 29th October If the photos haven't uploaded to your Dropbox folder yet, click here. Please read through the following information: Solids, liquids and gases are the **states** in which substances can exist in. Each of these states behaves differently to one another. In Science, we refer to the behaviour of a substance as a property. Water is a good example to imagine when we think of the **properties** of **solids, liquids** and **gases** because it is something that we are all familiar with. Water can take the form of ice, water and steam. When we think about the behaviour of each of these forms we get an understanding of the properties of solids, liquids and gases.
 * #1 Scientific Fact – Properties of Substances (Level 5)  **

The **shape** of a substance and its ability to be **compressed** are common properties that are used when looking at solids, liquids and gases. Imagine ice, water and steam and think about the shape that each of these takes. Imagine them again and think about trying to compress them. **Observations** tell us that ice (solid) has a defined shape and cannot be compressed. Water (liquid) takes the shape of the bottom of its container and can’t be compressed. Steam (gas) spreads to fill its container and can be compressed.

All substances have a **melting point** and a **boiling point.** The melting point is the temperature at which a solid changes to a liquid. The boiling point is the temperature at which a liquid changes to a gas. These changes are **physical changes** and the temperature at which they occur differs depending upon the properties of the substance. For pure water the melting point is 0oC and the boiling point is 100oC.
 * #2 Scientific Fact – Physical Changes (Level 5 & 6)  **

Substances change from a **solid** to a **liquid** and then to a **gas** as the temperature increases. The name of the process for the change from a solid to a liquid is known as **melting** and the name of the process for the change from a liquid to a gas is known as **evaporation.** As these changes are physical changes they are **reversible.** This means that as the temperature decreases substances can go through the reverse process and change from a gas to a liquid and then to a solid. Gas undergoes the process of **condensation** when it becomes liquid. Liquids will become solids when the temperature is less than the melting point. This process is called **freezing.**

Changes occur constantly in the world around us. Decreasing the **temperature** of a liquid will change it by freezing it into a solid. Water can change by simply mixing with and **dissolving** another substance. These examples are **physical changes** and can be **reversed** simply by increasing the temperature.
 * #3 Scientific Fact – Reversible and irreversible changes (Level 6)  **

Changes that are **irreversible** also occur. These changes are called **chemical changes** and result in a new substance being formed. The new substance cannot be changed back into the substance that it started as. A **colour change** or the creation of **bubbles** is always a sign that an irreversible change has occurred. Complete three activities from those listed below:

 * Week Beginning:** Monday 26th March

Work through the following documents in pairs or small groups of three.



What is gravity? Find 5 facts about gravity. Research 5 facts about Galileo Galilei (1564-1642). What famous experiment did he conduct at the Leaning Tower of Pisa? What did this experiment prove? Present your combined 10 facts in a creative way. WOW me! :)

There are many stories in newspapers and magazines about people who are using the scientific method to learn about the world. Examples include doctors who are trying to cure diseases, environmentalists who are trying to preserve the earth’s resources and astronomers who are trying to answer questions about the universe.
 * In the Newsroom**

Search the internet for a scientific article showing how science is being used to solve a problem or enhance knowledge. Present your findings in an interesting way on your iPad.

Ancient people believed many strange things about the earth and its place in the universe. For instance, ancient Greeks believed that the earth rested on the shoulders of Atlas. Later, people believed that the earth was flat and that humans could fall off the edge. Most people also believed that the earth was at the center of the universe.
 * Connection to History**

Investigate and learn more about the scientists who discovered the true nature of the earth. What was the major discovery of Nicholas Copernicus? Johannes Kepler? What tools did these men use to test their hypotheses?

This week, you will explore vision and sight.
 * Week Beginning:** Monday 27th February
 * Fred Hollows **

Fred Hollows (1929-1993) was a passionate **ophthalmologist** who became known for his work helping restore the eyesight of countless thousands of people in developing countries around the world. Fred held a special place in the hearts of many. According to Gabi Hollows, Fred's widow, he meant many things to different people. He was a husband, a father, a friend, a skilled **ophthalmologist** and, for a few politicians and **bureaucrats**, an irritating thorn in their side. But above all else, he was a **humanitarian**, which made him a terrific doctor. He truly believed it was the role of the doctor to serve, to help those in need.
