Senses Basics
What are senses?
Ways living things detect what is happening around them.
What system sends messages through the body?
The nervous system.
What is reaction time?
The time it takes to process information and act.
Do all animals have the same senses?
no
Do all animals have the same kinds of senses?
No, animals have different kinds of senses.
What do sense receptors do?
They detect information from the environment.
What are nerves responsible for?
Sending electrical signals to and from the brain.
Name one factor that affects reaction time.
Being tired, hungry, sick, or scared.
What special ability do honeybees have?
Detect Earth’s magnetic field.
What are two senses mentioned in the video?
Any two: touch, smell, hearing, etc.
Where are taste buds found?
On the tongue.
Name one main part of the nervous system.
Brain or spinal cord.
Why is fast reaction time important?
It helps survival.
How do animals use senses to survive?
to find food, avoid danger, and find mates.
How does the brain help the body react?
It processes information and sends signals to the body.
What is a signal?
A message to or from the brain.
What happens after the brain processes information?
It sends a signal to the body to act.
What body response speeds up reaction time in danger?
Adrenaline.
Are animals born knowing how to use their senses?
Yes, but they also learn as they grow.
How can reaction time affect survival?
Slow reactions can lead to danger like being eaten or not finding food.
Give one example of a sense.
Sight, hearing, smell, taste, or touch.
Describe the pathway from sensing to action.
Sense detects → signal sent → brain processes → brain sends signal → body reacts.
What is the “fight or flight” response?
A quick reaction to danger to either fight or run away.
Give one example of an animal sense from the video.
Tarantula touch, snake smell, frog hearing.
How can you improve reaction time results in an experiment?
Repeat trials and collect more data for accuracy.
