| Objectives | Students will be able to: (1) revise root, stem, leaf, flower; (2) explain photosynthesis in detail; (3) set up a starch test. |
|---|---|
| Materials | Variegated leaf plant (geranium), iodine solution, hot plate, ethanol, beaker. |
| Key vocabulary | photosynthesis, chlorophyll, stomata, xylem, phloem, starch |
| Engage (starter) | (10 min) “How do plants eat? They make their own food using sunlight. It’s called photosynthesis.” |
| Develop (main) | (35 min) 1. Photosynthesis equation: CO2 + H2O → (sunlight, chlorophyll) → glucose + O2. 2. Demo starch test: boil leaf in ethanol, add iodine → blue‑black where starch present. 3. Discuss variegated leaf: only green parts photosynthesize. 4. Draw and label a leaf cross‑section. 5. Write a lab report. |
| Plenary (close) | (10 min) Quiz: “What is the green pigment?” (Chlorophyll) |
| Assessment | Lab report includes method and conclusion. |
| Teacher notes | Teacher does boiling; safety goggles. |
| Objectives | Students will be able to: (1) name parts of a flower (stamen, carpel, petal, sepal); (2) explain pollination and fertilisation; (3) dissect a flower. |
|---|---|
| Materials | Real flowers (hibiscus), hand lens, scalpel, diagram. |
| Key vocabulary | stamen, anther, filament, carpel, stigma, style, ovary, pollination, fertilisation |
| Engage (starter) | (10 min) Show a flower. “Where do seeds come from? From flowers! Let’s look inside.” |
| Develop (main) | (35 min) 1. Discuss stamen (male – anther + filament), carpel (female – stigma + style + ovary). 2. Pollination: transfer of pollen; fertilisation: pollen meets ovule. 3. Dissect a flower, identify parts. 4. Draw and label. 5. Write a sequence: “First, pollination; then, ___.” |
| Plenary (close) | (10 min) Quiz: “What part becomes the fruit?” (Ovary) |
| Assessment | Dissection identifies parts; sequence correct. |
| Teacher notes | Link to importance of bees. |
| Objectives | Students will be able to: (1) explain why seeds need to disperse; (2) describe methods (wind, water, animals, explosion, humans); (3) design a seed for wind dispersal. |
|---|---|
| Materials | Seeds of different types (dandelion, burr, coconut), paper, scissors, tape. |
| Key vocabulary | dispersal, wind, water, animal, explosive, adaptation |
| Engage (starter) | (10 min) Throw a dandelion seed. “Why do plants send their seeds away? To avoid competition and spread out.” |
| Develop (main) | (35 min) 1. Show examples of each dispersal type. 2. Children design and build a seed that will travel farthest by wind (paper, tape). 3. Test outdoors. 4. Record distance. 5. Write an analysis: “The best design had ___ because ___.” |
| Plenary (close) | (10 min) Competition: farthest seed wins. |
| Assessment | Design tested; analysis thoughtful. |
| Teacher notes | Fun engineering tie‑in. |
| Objectives | Students will be able to: (1) define ecosystem; (2) describe a Jamaican ecosystem (mangrove, coral reef, rainforest); (3) create a food web. |
|---|---|
| Materials | Pictures of ecosystems, food web template, species cards. |
| Key vocabulary | ecosystem, habitat, community, population, food web, energy flow |
| Engage (starter) | (10 min) “What living things are in a Jamaican swamp? They all interact – that’s an ecosystem.” |
| Develop (main) | (35 min) 1. Discuss mangrove ecosystem: red mangrove, oysters, crabs, birds. 2. Build a food web using species cards. 3. Draw arrows showing energy flow. 4. Discuss what happens if one species disappears. 5. Write a paragraph: “In a mangrove ecosystem, the sun’s energy flows to ___.” |
| Plenary (close) | (10 min) Food web display; compare to other ecosystems. |
| Assessment | Food web shows at least 5 organisms; paragraph logical. |
| Teacher notes | Relate to conservation. |
| Objectives | Students will be able to: (1) define adaptation; (2) give examples from Jamaican plants and animals (cactus, iguana, bird beak shapes); (3) design an imaginary adapted creature. |
|---|---|
| Materials | Adaptation pictures, drawing paper, coloured pencils. |
| Key vocabulary | adaptation, structural, behavioural, camouflage, mimicry |
| Engage (starter) | (10 min) Show a Jamaican iguana. “Why does it have spines? To look scary! An adaptation.” |
| Develop (main) | (35 min) 1. Discuss structural (sharp claws, thick fur) and behavioural (migration, hibernation) adaptations. 2. Jamaican examples: cactus – spines reduce water loss; doctor bird – long beak for nectar. 3. Children design a creature adapted to a Jamaican environment (e.g., Blue Mountains, hot savanna). 4. Draw and label adaptations. 5. Present. |
| Plenary (close) | (10 min) Creature showcase; guess the habitat. |
| Assessment | Creature has at least 3 plausible adaptations. |
| Teacher notes | Encourage creativity grounded in science. |
