Title prediction
Heat-sensing noses
Read the title and predict what the conclusion may be.
Reading for main idea
What’s the conclusion of the study?
The study shows that dogs are indeed capable of sensing heat from warm-blooded animals. A specific region of their brain is activated by such signals, dogs can then use this information for hunting.
Read the passage and find the purposes, subjects, procedures and conclusions of the two experiments.
What’s the difference between dogs and humans sensing warmth?
