Kids, today we gonna learn two new words.
STIMULI and RESPONSE
So, what is Stimuli ? and whst is Response?
Let’s define Stimuli:
Stimuli are changes that occur around us in the environment.
Hey doc, the words changes around us sound deep.
Ok, ok. Let me give you guys some example of changes a.k.a Stimuli
Stimuli is known to us as touch, pain, heat, cold, sounds, food (chemicals) and light.
Let me further explain the stimuli to you.
– You feel and touch objects, that is a stimuli
– You look at things around you, that is a stimuli
– You feel cold, or hot, that is a stimuli
– You feel pain whe you fall down, that is a stimuli
– You hear sound, that is a stimuli
– You taste a burger, that is a stimuli
By now you should know what is astimuli. But, in our daily life, we deal with millions of stimuli and we call that Stimulus, which mean a lot of stimuli or plural form of stimuli.
When a stimuli or stimulus come to us. We response to it or them.
For every stimuli there is a response to it weather we aware or not. For example, when we touch anything hot like iron, we will feel pain. The response would be pulling back the hand to avoid pain.
Human need to respond to stimuli in order to protect themselves from danger or for survival.

Hey, kids. I got a question for you guys.
What is living thing?
You may think that is simple. Living things are people. Or maybe living things can move. Or maybe living things has life.
Living are people. Then what about plants, insects, animals ?
Living things can move. Well, my car can move. Do we say my car is a living thing.
Living things has life. What is life in the first place?
There are so many answer. So, today we are gonna get clear answer.
But seriously how should we really define living things ?
So here we go…
Living things are organisms such as bacterias, viruses, fungus, humans, animals, plants and a whole lot more. Well, I know there are some term that are new to you but nevermind that.
