Websites such as Kahoot, Quizlet, and Quizizz have a vast collection of games related to science education. In today’s technological world, one excellent way to get students interested in learning about physical and chemical changes is through interactive gaming. This approach helps to keep the learners involved as they learn to differentiate physical and chemical change in a fun and interactive way. You can find images of different scenarios or real-life examples of physical and chemical changes and ask the students to sort the images into two groups – physical and chemical changes. The students should label each scenario as either a physical or chemical change.Īnother way to engage students while teaching them to identify physical and chemical changes is by using sorting activities. You could give a scenario like melting ice cubes, rusting of iron, burning of candle wax, and crumpling of paper ball. You can create two columns on the board or in a worksheet, and ask the students to identify physical and chemical changes. While demonstrating, talk to your students about the changes and make a clear distinction between what happens when physical changes occur as opposed to chemical changes.Īnother method is to give students a side-by-side comparison of physical and chemical changes. Over time, the acid in the vinegar reacts with the iron to produce iron acetate, which shows a chemical change. For example, you can take an iron nail and place it in a beaker with vinegar. Here are some activities that can be used to teach students how to identify physical and chemical changes.Ĭonducting simple experiments is an effective way to help students understand the differences between physical and chemical changes. Helping them distinguish between the two is crucial in developing a deep understanding of science concepts. The mass of lead is a _property.As a teacher, it is important to ensure students understand the differences between physical and chemical changes. True or False: Dicing potatoes is a physical change. True or False: Bread rising is a physical property. The formation of gas bubbles is a sign of what type of change?ħ. Which of the following are examples of matter?Ħ. Aluminum Phosphate has a density of 2.566 g/cm3ĥ. HCl being a strong acid is a _, Wood sawed in two is _Ĥ. The following questions are multiple choice.ġ. The atoms in compounds are rearranged to make new and different compounds. Different elements or compounds are present at the end of the chemical change. A CHEMICAL CHANGE alters the composition of the original matter. The elements and/or compounds at the start of the reaction are rearranged into new product compounds or elements. This is a chemical property.Ĭhemical change results in one or more substances of entirely different composition from the original substances. Zinc reacts with hydrochloric acid to produce hydrogen gas. Metals in general have they chemical property of reacting with an acid. For example hydrogen has the potential to ignite and explode given the right conditions. At this time this is very difficult to do and you are not expected to be able to do it. Eventually you should be able to look at the formula of a compound and state some chemical property. It is quite difficult to define a chemical property without using the word "change". What elements, electrons, and bonding are present to give the potential for chemical change. volume: How much space the sample takes upĬhemical properties of matter describes its "potential" to undergo some chemical change or reaction by virtue of its composition.
