SCIENCE Science 5 is divided into 5 different units. Please click each picture to find more informative websites and games!
Classroom Chemistry
You will learn about the properties and interactions of some safe to handle household liquids and solids. You will test a variety of materials to see what happens when things are mixed together: what dissolves, what reacts and what remains unaffected. You will discover that when a solid material dissolves, it can be recovered as a crystal by evaporating the liquid. You will also learn that when two materials react to form a new material, the original materials cannot be recovered. As an example of a chemical reaction, you learn to produce carbon dioxide gas and show that this gas differs from ordinary air.
Electricity and Magnetism
You will learn about electricity by building and testing circuits. Using batteries, bulbs and wires, you will construct simple circuits and test the effects of various modifications. Through such tests, you will discover that a circuit requires a closed pathway for electricity and that some materials conduct electricity and others do not. You will learn that an electric current can affect a nearby magnet and that this property of electricity is used in making electromagnets and motors. Potential dangers are examined, as you learn about the safe use of electricity.
Wetlands and Ecosystems
In this unit you will learn about different types of wetlands in and around the areas where we live. Wetlands are grouped into the following classes: bog, fen, marsh, swamp and shallow water. When we think of wetlands we classify them as land that has been saturated with water and has poorly drained soil, where the depth of the water is no greater than 6 meters. You will learn about the living and non-living plants, animals and organisms found in these areas. We will be studying the life cycle of various organisms that live in or around wetlands. In this unit we will also take a look at the environmental impact of human interaction in and among the wetland environment.
Mechanisms using Electricity
You will build electrical devices for a variety of purposes, using knowledge gained in the previous topic. Tasks that you are assigned may include such things as making a switch from scrap materials, making a device to control the speed of a motor, making a burglar alarm and lighting three bulbs from one source. Through work on these tasks, you will learn the role of various components and control devices that are part of an electrical system. At the same time, you will develop skills of problem solving and teamwork.
Weather Watch
In this unit you will learn about weather phenomena and the methods used for weather study. You will learn how to measure temperatures, wind speed and direction, the amounts of rain and snow, and the amount of cloud cover. In studying causes and patterns of air movements, you will learn about the effects of uneven heating and cooling and discover the same patterns of air movement in indoor environments as are found outdoors. You will also learn about human actions that can affect weather and climate and study the design and testing of clothing used as protection against the weather.
