Spores are similar to seeds but they only need one parent not a male and a female parent like is needed to make seeds. Spores are also much smaller than seeds and do not have food reserves inside them.
Tis forTug o' war
A tug of war is when two groups of people pull on opposite ends of a length of rope. The winning team is the one that pulls it furthest in their direction. Usually there is a marker in the middle of the rope so you can tell how far the teams have come. Sometimes there is something like a pool of water or mud in the middle so the losing team falls in.
Warsaw is the capital city of Poland. The population of Warsaw is around 2.6 million.
Wore is the past tense of wear. It might mean damage made slowly, for example "the horse wore a track into the grass" or it might mean clothing that has been worn, for example "she wore a green dress to the party".
