Inventions and discoveries activities
Hello class. Today we will continue in our natural science book on page 106 and we will learn all about the difference between inventions and discoveries. Let's get started.
00:00:00
Discoveries are things that we find. Inventions are things that we make that didn't exist before.
00:00:18
Petroleum, a potato, and fingerprints are discoveries. A wheel, a microscope, and a mop are inventions.
00:00:29
Let's look at these two pictures and define discoveries or inventions.
00:00:42
Okay, so here in this first image we have a computer, a bicycle, and a mobile phone.
00:00:52
We know that two of these require electricity, and all of these are
00:01:02
machines that have many parts. So this picture shows you three different
00:01:11
inventions, so I want you to please write I for the inventions, okay? In the next
00:01:21
image we have rice, fire, and tomatoes. We have two types of food that we harvest in fields
00:01:30
with agriculture and we have fire which is a natural element. All three of these pictures show
00:01:45
discoveries. Discoveries are things that humans find out in nature and use to eat
00:01:55
or to help them with life. So please write D for discoveries. Next we will look and classify each
00:02:04
picture with its object name under a discovery or invention. A wheel spins around and helps move
00:02:16
objects. So you will have a wheel on something such as a car or a bicycle or a scooter. A wheel
00:02:31
is an invention. Next we have petroleum. Petroleum is an oil and we dig this oil out from the ground.
00:02:42
So petroleum exists from nature so it is a discovery. Next think of a microscope.
00:02:58
A microscope is a machine made of many different parts. Scientists use
00:03:09
microscopes to help them look very closely at small objects. You can use a
00:03:18
microscope for any kind of other invention that you need. So we will put
00:03:27
microscope for inventions.
00:03:34
Next think of potatoes which are a food, fingerprints
00:03:39
which are a body part, and mop which has two parts
00:03:46
and is a machine that we use to clean. It's a tool we use to clean the
00:03:54
house. So use these last three, potatoes, fingerprints, and mop, and think, is it a
00:04:00
discovery or invention? And please write each under its correct box. Let's now
00:04:08
continue with exercise three. Complete with words from activity two, then read
00:04:18
out loud. I have helped you fill in the first sentence so that you can complete
00:04:27
the second on your own. I have used the pictures as I wrote them in under
00:04:35
discoveries and filled in one, two, and three different discoveries to finish
00:04:45
the sentence. So here I have potatoes, petroleum, and fingerprints are discoveries because they
00:04:53
already existed. Now I want you to use the remaining three, that is the three that are left
00:05:02
on your inventions side of the diagram chart and please fill in three different inventions
00:05:13
that you can see above. For example, a wheel is an invention so I will write wheel and two more
00:05:24
are inventions because someone made them. So someone created these using
00:05:37
