Battle of the Brains answer key

This is a worksheet for the video "Horizon: Battle of the Brains", which covers the topic of intelligence and intelligence testing in particular. It would probably work best in a Psychology or AP Psychology unit.

The video is available on youtube and shows seven people from seven different careers undergoing a battery of intelligence tests. The video probes into how these tests measure intelligence, whether they are effective or not in measuring intelligence, and shows the latest research from modern intelligence theorists.

The worksheet has basic questions about events in the video but also asks students to "try out" some of the intelligence tests along with the participants and also requires some reflection on what students learned the most.

Answer key is included.

Set a Purpose for Reading
Draw attention to the “As You Read” question. Have students identify signs of intelligence in animals. 

1. Based on the article, what are some reasons animals use tools?

R.9 Integrate Information

2. How is a dolphin’s unique whistle similar to a human name? 
A dolphin’s unique whistle is similar to a human name in that it can be used by other dolphins to identify that dolphin.
R.5 Comparison

3. How does the author support the claim that octopuses have a lot of brainpower?
The author explains that octopuses have a central brain and a complex nervous system that enables their arms to move as if they’re making their own decisions.
R.8 Reasons and Evidence

FEATURED SKILL: Main Idea
Use “Heading Hashtags” to have students create hashtags identifying the main ideas of each boxed section. Offer an example: #DolphinsTeamUp. 
R.2 Main Idea

Multilingual Learners
Display the closed captions as you watch the video to help students make a stronger connection between spoken and written English. 


Striving Readers
Point out the phrase “big noggins” in the elephant section of the article. Ask if students have ever heard the term noggin, and explain that it’s an informal way of saying “head” or “brain.” 


Critical Thinking
Discuss: Why do you think scientists have such a hard time agreeing on a definition of intelligence in the animal kingdom? How would you define animal intelligence? Explain your reasoning.
