Students use a diagram to answer questions about water reserves, the main difference between lake and sea water, and to explain how water in the ocean could end up falling as snow in the mountains.
Students interpret a table of distances for a long jump competition, written to two decimal places, finding the longest and shortest jumps and ordering sets of three numbers.
Students use diagrams to answer questions about atoms, elements, compounds, and mixtures. They are then asked to use these words to describe the differences between diagrams.
