NATURAL SCIENCE
UNIT - MATTER AND MATERIALS
LESSON: FORCES EVERYWHERE
...
Let's start cheering up... Singing our Unit's song:
....
Now... We have been learning about properties of matter... Now that we know about that... I have a question: If we want to use and transform matter... How can we do that? How can we make it happen??
... Well, to make it happen we have to use forces... Sometimes forces are produced by humans or animals... And sometimes they are produced by nature... Forces transform things... Forces are everywhere... Like on this picture... Here we can see an archer transforming the BOW and THE STRING 🏹 ... using the force of his arms:
In this video we can see an explanation of what FORCES are:
And this video shows you how forces can change the motion and the shape of objects:
So... We have learned that:
- If we want to transform matter we need to use forces.
- Forces can change things around us.
- Forces have different effects on things.
Now, this are the effects that forces can produce:
OUR LESSON'S SUMMARY:
Your homework:
You have to copy this summary in your notebook and you have to study it... And you also have to study and review the other summaries from this Unit.
REMEMBER: After studying your summary you should explain it to somebody from your family, if they are very busy... Then you can pretend (imagine) that you are explaining it to your classmates... That will help you to understand it and memorize it better!
