OS5-3R Grade 5Properties and Changes in Matter

Rated 3.00 out of 5 based on 1 customer rating (1 customer review) $8.50 Author : admin Explain the concept of matter. Different States of Matter (solids, liquids, gases). Explore changes of State. Investigate the difference between physical changes which are reversible and chemical changes which are not reversible. When examining changes of state students must know how to heat samples safely. Look at the three states of matter. Physical Change means that a substance can change from a solid to a liquid to a gas and back. Chemical change involves the formation of a new substance. Properties of materials determine the use they have and their effect on society and the environment. What is the environmental impact of the process of changing one product into another. Sample: Change of Wheat/Corn/Rice into flour. /Flour into breads/pasta/crackers/wall paper/paste/new trees/lumberyard scraps & recycled paper products into pulp/petroleum into plastic/soft drink bottles-some ends up in landfills and some are recycled. Chemical preservatives makes food last longer but preservatives have an impact on human health. Recycling can help keep rubbish out of landfills. Mass is everything that has mass and occupies space. States of Matter: Evaporation-water from a wet cloth/condensation/freezing/solidification/steam from a boiling kettle on a cold plate/water in ponds solidifies or freezes in winter. Students need to follow safety procedures when working with hot appliances and materials. E.g. – switch off hot plates. Use of appropriate instruments –thermometer/single-pan balance. Use scientific inquiry to investigate changes in matter. Understand condensation/solidification/what causes a change of state. When clearing up a liquid spill what materials is good to use-paper towel/sponge/terry cloth. Discuss physical changes that are reversible-water to ice then back to liquid then to water vapour. Chemical change-chrome on a bicycle rusts and cannot be reversed. Egg boiled cannot go back to its raw state.
