Melting & boiling points differentiated worksheets

3 worksheets (Easy; Medium; Difficult). Based on a PowerPoint I found on here. I tried this with my bottom set year 7 class and it worked really well. Best if printed in color because of the visual temperature scale.Hope it helps!You might want to change the part at the very bottom in the table on the far right column where I put room temperature at 25degrees! probably 19-21 is more accurate! Whoops!
