a better crowd comment
0:22
a key to being an effective study here is to study actively
0:25
not passively my colleague Becky Thompson is gonna
0:28
introduce concept mapping which is a great way to be enacted steadier
0:33
take away the key thanks Craig
0:36
do you ever feel really overwhelmed with the amount of information that you have
0:40
to study
0:41
well a concept map is a great way to
0:44
organize the information in a really visual way see you're taking all
0:48
important people terms events place this and you're forming these distinct
0:53
connections between I'm
0:54
so that you have a really cohesive understanding up the contact 7 to give
0:59
you three steps
1:00
in order to be able to build a concept map the first step
1:03
is you need to choose your main idea so this is probably the unit title or the
1:07
section title or if it's a smaller quiz
1:09
maybe it's just one single topic in this case we use parts of a style
1:14
so now you take this main idea and you're gonna put in the center of your
1:18
concept map
1:19
in a box see you know you can always reference back to that main idea
1:23
you know what your concept map is covering the second step
1:27
is you need to list your key terms so these are all the important things that
1:31
you know you're going to be tested on
1:33
so for example with the park service thou you might have the nucleus
1:37
DNA chromosomes my to contre a
1:41
cell membrane ribosomes back you all
1:44
things like that would be really really important terms that you would see
1:48
on a test covering parts of a cell the third step
1:52
is your gonna actually start creating your map so you already have your key
1:55
idea in the center
1:57
in a box and you're going to make connections from there
2:00
so you're going to use your key term list and you're gonna go one by one
2:04
30 each key term connecting at in some way
2:08
to the main idea senator so far for example will start with the nucleus
2:13
so this is the control center have the cell so if we connected it to you this
2:18
talent concept map we might say that the spell
2:20
is controlled by the nucleus and the nucleus would go in a circle because
2:24
that's a key idea
2:26
thing going further from there we know that chromosomes are inside of the
2:30
nucleus
2:30
so we might extend a line from nuclear test and say that the nucleus contains
2:35
chromosomes
2:36
and even further from there we know that DNA is what makes up chromosomes
2:41
so we might extend a line from chromosome saying
2:45
chromosomes I made up a DNA then you go back to your list have key terms
2:50
adding them one by one to the concept map until you get to the
2:54
and so once you're finished you have a whole visual
2:58
understanding a all the key terms that you need it now
3:01
and what's really cool is you can either hand right
3:05
a concept map or you can use digital tools such as a website called
3:09
bubble and you can go to Bible that you ask and create concept map I might
3:14
so the next time you have to study for something with
3:17
a lot of key terms key people key places key events
3:21
a concept map is a great visual tool

Task 1

First of all, we are going to do a brief debate. I am going to ask you some questions and I encourage you to put up your hand and express yourself to the rest of the class.

Question 1: What is a lightning?

Question 2: What does a bulb work?

Question 3: Do you know what is the material our houses' switches are made of?

Task 2

I want you to read text 1. Pay attention to the words in red.

Text 1 : We are surrounded by objects. These objects have a size, they can be touched, can be perceived and they can be measured. These objects are a substance in theirselves. A substance is formed of atoms. Atoms are the basic and smallest elements in a substance. Each atom is formed of particles that have electric charge. There are three types of particles: the electron, the proton and the neutron. The electron has got a negative charge and the proton a positive charge. A neutron has got no charge at all. Electrons are the cause of electrical phenomena.

Now, I want you to work on your own and create a concept map for text 1. You can watch again the video in this lesson to help you create the concept map in case you need it. If you don't understand any word in the video, just click it. 

Task 3

Read text 2 and then do exercise 1.

Text 2: The electric current is electrons in motion through a material. When materials allow a electric current pass throughout them, they are called conducting materials. Metals are conducting materials. And when electric current cannot flow through a material, this is called a non-conducting material. Plastic materials and wood materials are non-conducting. The electric current flow is produced because electrons move to an area where the quantity of protons there is higher than the quantity of electrons. For example, in a battery, the area where protons are located is called the positive terminal and electrons move towards there. Electrons start the movement in what is called the negative terminal.

Now, I want you to do exercise 1 in pairs and then participate in a debate comparing your answers with the rest of your classmates.

Task 4

The teacher is going to choose six out of all of you. Each of the chosen students has to decide to be an electron, a proton or a neutron. The classroom in divided in three areas. One area is full of electrons, the another area is full of protons and in the other one the quantity of electrons is the same of protons. You have to move into one of these three areas and the rest of the class have to make an statement about your movement.
