Students read about sexual and asexual reproduction in plants, identify an asexual plant by budding characteristics and answer two questions on the advantages of asexual reproduction.
Students identify the variables to be kept constant, and the variable to be different, when they plan a fair test to show if green plants need light to grow.
Students read some information about testing the absorbency of different papers. They outline two features that need to be kept the same if the tests were to be fair.
