Natural Sciences and Technology Grade 6 Term 2: Matter and Materials Dissolving
Topic 4 Dissolving Drawing a graph Gr 6 Natural Sciences and Technology Term 2, Topic 4
Draw 3 line graphs [1] You are asked the following in question 5, Worksheet D: draw 3 line graphs showing how long it takes for salt to dissolve at different temperatures You can begin by: drawing the x-axis on the x-axis you show the passage of time in one minute intervals give the x-axis a title Gr 6 Natural Sciences and Technology Term 2, Topic 4
Draw 3 line graphs [2] After you have drawn the x-axis: you need to draw the y-axis on the y-axis you show what has happened to the salt that you are trying to dissolve give the y-axis a title Gr 6 Natural Sciences and Technology Term 2, Topic 4
Draw 3 line graphs [3] After you have drawn the x-axis and y-axis, you need to draw lines to show the your data (information): draw a line showing the time it took for salt dissolve in cold water it will be easier to do this on graph paper so that you can use the lines to guide you to plot your line
Draw 3 line graphs [4] After you have drawn the line to show how long the salt took to dissolve in cold water: draw a line to show how long the salt took to dissolve at room temperature this line must look different from the cold water line you want to help people tell the difference between the two sets of data (information) Gr 6 Natural Sciences and Technology Term 2, Topic 4
Draw 3 line graphs [5] After you have drawn the line to show how long the salt took to dissolve at room temperature: draw a line to show how long the salt took to dissolve in hot water Remember that this line must look different from the lines showing how fast the salt dissolved in cold water and at room temperature
Draw 3 line graphs [6] Now you must give your graph a title:
Draw 3 line graphs [7] Finally you must provide a legend explaining what the different lines represent:
Draw 3 line graphs [8] Well done! Your graph is now finished showing all the data you collected in your investigation
