In this practical task students design a net for a lidded cardboard box to hold 3 "chocolate bars" represented by hundreds blocks. They then cut out and construct the box.
Students compare drawings of a healthy and unhealthy plant and decide which quantitative and/or qualitative data distinguishes them. This is a mathematics/science resource.
Students are given the formula of two different types of chlorophyll. Students name all the elements present, and how the number of atoms differs between the chlorophylls.
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.
For this task students are provided with a diagram showing the landmasses that originally made up Gondwanaland. Students are required to identify and use their own knowledge to indicate the evidence which indicates that these landmasses were once joined together.
