Students explain the function of the veins, waxy layer of the upper surface of the leaf, how the shape of the leaf traps light energy and why the upper surface of the leaf is a darker green than the lower surface.
A bar graph showing the percentage of endangered species threatened by predation, competition, and/or habitat loss is given. Students use this graph to answer questions and explain the terms; predation, competition, and habitat loss.
Four diagrams showing different ways plants store food (tuber, bulb, corm, and a tap root) are provided. Students are asked to identify which method of food storage different plants use. Three short answer questions are also included.
Task: Students interpret information about couch grass from a diagram and explain why its special features make it difficult to get rid of. Assessment focus: special features ensure a plant's survival.
Task: Demonstrate understanding of the pupil reflex of the eye, and apply this to answering questions about sunglasses safety. Extension questions probe understanding of who decides on and applies safety standards. Assessment focus: effect of UV light on the eyes and how it can be mediated by simple sunglasses technology.
Task: Use written text and pictures to explain how the special features of Old Man's Beard help it survive. Assessment focus: identifying how the special features help this plant to survive.
Task: Use understandings about heat energy and insulation to describe how adaptations help Emperor penguins survive in Antarctica. Assessment focus: adaptations for keeping warm in cold conditions.
Task: Students decide whether four dinosaurs are meat-eaters or plant-eaters, and justify their answers. A list of features of each group is provided. It may be completed individually or as a group assessment. Assessment focus: using evidence.
Decide whether the photographed animals are reptiles or not, and justify responses. (A fact file giving the features of reptiles is given.) Answer a question about why scientists have an agreed way of grouping living things. Assessment focus: using science-based classifications.
Students are given four pictures, and are asked to draw a circle around the picture that is not a bird, and then give a reason for their choice. Similarly, they circle animals that are not mammals, fish, and molluscs.
