Using tongues in What do animals eat – Class 6 Science Experiment

Chapter Name: What do animals eat

Activity Name: Using tongues in What do animals eat

Activity Description:

Compare how a frog, cow, and dog use their tongues.

Required Items:

• Frog
• Cow
• Dog
• Observation sheet or notebook
• Pen or pencil

Step by Step Procedure:

1. Begin by observing each animal separately.
2. 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.
3. 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.
4. Finally, observe the dog and note down its tongue movements and actions. Pay attention to how it uses its tongue to eat and drink.

Experiment Observations:

1. Frog:
   • 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.
2. Cow:
   • 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.
3. Dog:
   • 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.

Precautions:

1. Ensure the safety and well-being of the animals during observation.
2. Keep a safe distance from the animals and do not disturb them while observing.
3. If necessary, consult a professional or veterinarian for guidance on animal handling.

Lesson Learnt from Experiment:

1. Animals have different types of tongues adapted to their specific dietary needs and behaviors.
2. The frog’s long, sticky tongue is specialized for catching fast-moving prey.
3. The cow’s large, muscular tongue helps in gathering and breaking down vegetation.
4. The dog’s flexible tongue is versatile and assists in eating, drinking, and self-grooming.
5. Tongues play a crucial role in facilitating food intake and consumption for different animals based on their evolutionary adaptations.
