The document discusses an experiment to investigate the factors needed for plant seeds to germinate and sprout. It introduces the terms germination and seedling. It then outlines three experimental set ups to test if seeds need water, light, or warmth to germinate. The first set up tests if seeds need water by having some seeds dry and some wet. The second tests if seeds need light by having some in light and some in darkness. The third tests if seeds need warmth by having some in a warm place and some in a fridge. Students are instructed to record the height of seedlings over seven days to see which conditions promote growth. They then write a conclusion about what seeds need to germinate based on the results
