Tue 24 Mar 2026	1Remember the four main stages of the Anopheles mosquito life cycle. 2Ask: What insects have you seen near water in your compound or village — can you name them? Learners share answers chorally. 3Show the chart/diagram of the Anopheles mosquito life cycle; ask learners to point and count how many different forms they see.	STAGES OF THE ANOPHELES MOSQUITO LIFE CYCLE 1Display the chart/diagram and use the textbook to identify and name each of the four stages: egg, larva, pupa, adult. 2Learners draw and label the four stages in their exercise books using the Science kit/specimens or chart as reference. 3Ask: Why does the Anopheles mosquito lay eggs in water? Learners discuss with a partner and share one reason. CHARACTERISTICS AND DURATION OF EACH STAGE 4Using the textbook and chart, describe how each stage looks different — eggs float in rafts, larvae breathe through a tube, pupae are comma-shaped, adults have long legs and wings. 5Learners compare the larva and pupa stages by writing two differences in their exercise books. 6Explain: The entire cycle from egg to adult takes about 7–10 days in warm water; ask learners why this speed matters for malaria spread. ECONOMIC IMPORTANCE AND IMPACT ON HUMANS 7Present two impacts: negative (transmits malaria, costs Ghana millions in healthcare) and positive (food for fish and birds, research opportunities for scientists like Dr. Ama). 8Learners classify statements as 'helps humans' or 'harms humans' using examples from the textbook and write their classifications in exercise books. 9Challenge: Why might controlling Anopheles mosquito breeding sites (emptying water containers) be cheaper than treating malaria? Learners propose one reason.	1Textbook 2Science kit/specimens 3Chart/diagram of Anopheles mosquito life cycle 4Exercise book	1Learners whisper the four life cycle stages to their partner in order: egg, larva, pupa, adult. 2One representative from each row shares one economic impact (positive or negative) of the Anopheles mosquito. Exercise 1Draw and label the four stages of the Anopheles mosquito life cycle, then write one sentence explaining why controlling mosquito breeding sites is important for Ghana.
