Investigating Animal Growth in the Costa Rican Rainforest Ecosystem

The video covers lessons 1.4 and 1.5, focusing on how animals grow and use food matter. It introduces scientific argumentation, emphasizing the importance of evidence in forming claims. Students explore the Costa Rican rainforest ecosystem to understand why animals aren't thriving. The video includes activities on observing otters and using a digital simulation to model food matter in ecosystems.

What is the primary goal of the project discussed in the Costa Rican rainforest ecosystem?

• To increase the number of plant species

• To restore and improve the health of the ecosystem

• To build a research facility

• To introduce new animal species

In scientific argumentation, what is a 'claim'?

• A list of observations

• A detailed experiment

• A proposed answer to a question

• A random guess

Which of the following is NOT a claim about what alligators eat?

• Alligators eat insects

• Alligators eat other animals

• Alligators eat plants

• Alligators eat rocks

What evidence supports the claim that alligators eat other animals?

• Alligators are seen eating plants

• The number of fish increased after alligators arrived

• Alligators are observed eating birds

• Alligators are seen eating rocks

What is the definition of 'evidence' in the context of scientific argumentation?

• A hypothesis

• Information that supports an answer to a question

• A conclusion

• A theory

What are animals made of, according to the lesson on how animals grow?

• Matter, which is made of molecules

• Cells
