Activity Name: Using tongues in What do animals eat
Compare how a frog, cow, and dog use their tongues.
- Observation sheet or notebook
- Pen or pencil
Step by Step Procedure:
- Begin by observing each animal separately.
- Observe the frog and note down its tongue movements and actions. Pay attention to how it uses its tongue to catch and eat its food.
- Next, observe the cow and note down its tongue movements and actions. Observe how it uses its tongue to graze on grass or other vegetation.
- Finally, observe the dog and note down its tongue movements and actions. Pay attention to how it uses its tongue to eat and drink.
- The frog has a long, sticky tongue.
- It extends its tongue rapidly to catch insects and other small prey.
- The tongue retracts quickly, bringing the food into the frog’s mouth.
- The cow has a large, muscular tongue.
- It uses its tongue to gather grass and other vegetation into its mouth.
- The tongue helps in breaking down the food and pushing it towards the back of the mouth for swallowing.
- The dog has a flexible tongue.
- It uses its tongue to lap up water and lick its food.
- The tongue also helps in cleaning itself and cooling down by panting.
- Ensure the safety and well-being of the animals during observation.
- Keep a safe distance from the animals and do not disturb them while observing.
- If necessary, consult a professional or veterinarian for guidance on animal handling.
Lesson Learnt from Experiment:
- Animals have different types of tongues adapted to their specific dietary needs and behaviors.
- The frog’s long, sticky tongue is specialized for catching fast-moving prey.
- The cow’s large, muscular tongue helps in gathering and breaking down vegetation.
- The dog’s flexible tongue is versatile and assists in eating, drinking, and self-grooming.
- Tongues play a crucial role in facilitating food intake and consumption for different animals based on their evolutionary adaptations.
