How does a frog get its food in What do animals eat – Class 6 Science Experiment

Chapter Name: What do animals eat

Activity Name: How does a frog get its food in What do animals eat

Activity Description:

The experiment aims to observe and compare the feeding behaviors of a frog and a lizard, specifically focusing on how they use their tongues to catch and consume their food. By studying these animals’ feeding techniques, we can understand the differences in their hunting strategies.

Required Items:

  • Notebook or paper
  • Pen or pencil
  • Internet or reference materials (to gather information about frog and lizard feeding habits)

Step by Step Procedure:

  1. Research: Begin by gathering information about the feeding habits of frogs and lizards. Learn where they live, what they eat, and how they catch their prey.
  2. Frog Observation: Find a suitable location, such as a pond or wetland, to observe frogs in their natural habitat. Spend some time observing how a frog catches its food. Note down the following observations: a. Look for a frog that is actively hunting. b. Observe how the frog positions itself and prepares to catch its prey. c. Pay attention to the frog’s tongue and how it extends to catch insects or other small animals. d. Observe the process of the frog swallowing its prey.
  3. Lizard Observation: Locate an area where lizards are commonly found, such as a garden or a rocky area. Observe a lizard as it hunts for food. Take note of the following observations: a. Look for a lizard that is actively searching for prey. b. Observe how the lizard moves and positions itself to catch its food. c. Note how the lizard uses its tongue, if applicable, or any other specialized hunting techniques. d. Observe the lizard consuming its food.
  4. Comparison: Compare the observations of the frog and the lizard regarding their feeding techniques. Pay particular attention to how they use their tongues to catch and consume their prey. Note down the similarities and differences between the two animals.

Experiment Observations:

  1. Frog Observation:
    • The frog positions itself near the water’s edge, waiting for prey to approach.
    • When an insect comes within range, the frog rapidly extends its sticky tongue.
    • The insect gets stuck on the frog’s tongue, and the frog quickly retracts its tongue back into its mouth.
    • The frog then swallows the prey whole.
  2. Lizard Observation:
    • The lizard actively hunts by stalking its prey or waiting for an opportunity to pounce.
    • Unlike the frog, the lizard doesn’t use its tongue to catch prey. It relies on its quick movements and sharp teeth to capture and consume its food.
    • The lizard bites its prey and tears it into smaller pieces before swallowing.


  1. Observe the animals from a safe distance and avoid disturbing their natural behavior.
  2. If observing wild animals, do not attempt to touch or handle them.
  3. Ensure that the observation areas are suitable for the respective animals, such as a pond for frogs and a lizard habitat for lizards.
  4. Respect the natural environment and do not cause any harm to the animals or their habitats.

Lesson Learnt from Experiment:

Through this experiment, we learned that frogs and lizards have different feeding techniques. Frogs use their sticky tongues to catch prey, while lizards rely on their agility and sharp teeth.

This difference in feeding strategies is adapted to their respective habitats and the types of food available to them. Understanding the diverse ways animals obtain their food helps us appreciate the complexity of nature and how different species have evolved to survive and thrive in their environments.
