Look Who's Talking

The video explores the essential role of plants in human life, highlighting their contribution to oxygen production and diet. It delves into how scientists conduct investigations to answer questions about plants, using examples like the Venus flytrap and Charles Darwin's experiments on plant light sensing. The video emphasizes the scientific method, from forming hypotheses to sharing results. It concludes by acknowledging the vast unknowns in plant science, encouraging further research and discovery.

Why are plants considered crucial for human survival?

• They provide shelter.

• They produce oxygen.

• They repel insects.

• They create rain.

What is the first step in a scientific investigation?

• Sharing results.

• Conducting an experiment.

• Making a guess.

• Asking a question.

How does the Venus flytrap detect insects?

• By feeling hairs being touched multiple times.

• By sensing vibrations in the air.

• By detecting changes in temperature.

• By smelling the insect.

What did Charles Darwin hypothesize about plant stems?

• They need more water to bend.

• They sense light at the tip.

• They can communicate with each other.

• They grow faster in the dark.

What is a major unknown in plant science?

• How plants absorb water.

• How plants communicate with each other.

• How plants grow in soil.
