Year 10 have been learning about word equations as part of our recent science learning at Lansdowne School. This is the process that describes what happens when two different scientific properties come together.
This work started off with the students understanding that every equation starts with a reaction. This then leads to an end product. An example of this might be hydrogen reacting with oxygen, to then produce water.
Year 10 then completed a word equation puzzle. A number of cards with various properties printed on them were carefully cut out. The challenge was for the students to use their existing scientific knowledge to help form a word equation.
Miss McNie asked the pupils if there was any developing pattern that they could observe. It was recognised by one class member that the name of the end products changes ever so slightly when compared to the two properties that have formed the reaction. An example of this is carbon and oxygen reacting to produce carbon dioxide.
The first puzzle involved adding a metal to an acid to make a salt. Once the students had managed to complete this, they then went on to look at adding acid to a metal to produce a carbonate.
