Begin the lesson by introducing the concept of stimuli and responses in living organisms. Discuss how these responses are crucial for survival.

Engage students with a thought-provoking question: How do you think plants and animals respond to changes in their environment?

Explain the different ways plants and animals respond to stimuli, using examples such as phototropism in plants and meerkats' response to predators.

Use the video 'Responses to Stimuli' to illustrate various examples of how organisms react to environmental changes.

Watch the video 'Living and Non-living Things – Can you tell the difference?' to reinforce the understanding of living organisms' characteristics.

Facilitate a discussion on how different animals, like kangaroos and meerkats, use their senses to respond to environmental stimuli.

Conduct an experiment where students observe how plants respond to light by placing them in different lighting conditions.

Use the assessment 'Plants Grow and Respond to Changes' to guide students through the process of making predictions and analyzing results.

Assign students to observe and record how a pet or a plant at home responds to changes in its environment over a week.

Use the assessment 'Animals Respond to Changes' to evaluate students' understanding of animal behavior and adaptation.

Have students share their observations and reflections on how living things respond to stimuli.

Discuss the importance of quick responses to stimuli for survival, using meerkats as a case study.

Administer the 'Review – Living Things Around Us' assessment to gauge overall comprehension of the unit.

Encourage students to explore further by researching how different animals adapt to seasonal changes in their habitats.
