everybody monica and welcome back to season two of construct and stem so season one we will have a lot of different things that we build and we talked about the stem and i always focus on engineering because you know i love the engineering component so we talk about different concept as we build and i know as you looked at the products i was i was building you probably saw a lot more concept you could teach by a building when i first started this one of things i thought was really need is i'm not sure if for me with the book by andrew clement in that book of the all the landry noodles he talks about i mean it wasn't for this purpose but he mentions in the book and it's a very funny book  very very great that's a really nice book he talks about kids learn by doing and they teach themselves and sometimes i find that during my classes that actually happens because i try to teach concept and we build a we do something and they learn i can tell them to plug this and here or do that and they don't actually learn until they do it themselves it's always interesting when they're working by a partner in the partner might be doing a little faster and that person tries to help them and i always try to stop it because i think everybody should do it themselves because that's how you are so we're going to revisit electronics i now you probably i did a lot on it and this is season two and i'm revisiting that and only reason i revisit is because a lot of great things has happened throughout the year with electronics and i just want to talk about some of things now that i have i actually started electronic it's system online and you can get at my website debbie construct dot com for anyone who's interested in just learning basic like tronics and all it is a lot of kit with cards and also i'm putting the book in it and it's just an interesting i think product for you to work with your basics so they understand it i always uses introduction to robotics because if you can use robotics basically if they're it's a more advanced robotics it's going to use some type of brain some type of controller reason i do get them is because my kids take them home so when they build a circuit they can take it home and then when i have them again it's funny because they add to it and then they take it home so i'm at five or six of these boards at home but each time they're learning something a little different and my kids are repeat are becoming experts in electronics so hopefully they'll be electronic and generic who knows ok so let's talk about the breadboard again now before i mention that the bread has what we call rolls across and columns down right so if you want something to be connected in the bread there has to be in the row and if you see here you can see the metal strips going across that just shows you that though across the rolls across or connected if you want to connect something and the way it works everything has to be connected and if it's not connected that's because in an open circuit so  to that so when it does the bread what actually has what we call a conductor in it where electricity flows through so this is the conductor on a spread board so these breadboards i like and i get them from amazon e bay different places depending but one of the things they have is a grid and it's nice sometimes to teach the grid concept and so some of these come we created some down cell but i still teach project i should say the thing about l e d's if you get the clear once they have different colors and the only way you can tell by whatever you buy in might have the colors that way but if you one two three three down we put that thing i forgot to mention out i'm going to go like i haven't done this class before about just mention again this l e d is one directional so the long and short end and that you have to there's a lot of other things you can look at because one is kind of circle one is square but really when you're working with kids you look at the long or short in the long in is positive to shore in it's negative so the electricity is going to flow to the positive and it's one directional so we're going to put the positive pole in three and the negative pole and five simple i know we've done this before and if you weren't with me you're starting over and that's  and i actually i stretched it over so you stayed in three and your seat and five and the four open because it's easier and of course if you so just can put in like that very simple simply disability simple thing to do and i think it's really nice to work with kids and then i have these little wires that i get against amazon e bay were ever usually they use black and red i use orange red whatever i have someone who's orange and black this time so orange is going to use for my past in a black family from an editor so i'm going to put orange in the in the number three row so bay really easy to get and i use least three boat batteries but in batteries i just stick it in on the back they had a sore point he parts that weren't connected to the breadboard you do not want to put your fingers on that doesn't go to six that's why i use in class but i do something else of a sudden it's going to three so if i do this correctly i should be able to just put this in three so i have my positive connected and if my negative one of things is sometimes it's hard for them to see so when i do it it's easy if you just if you have your kids just put it in this role with you can see this row this column i should say this c it's twelve so three and twelve simple right ok so next thing we did we added a switch remember if not again you switch was a single pole double throw switch and it negative on and i put the positive on either one of the other ends so i can uses on and off for going to two things windows on arm and they were going to switch it to two surfaces we should have enough time for that so the put it here i pu move it because i'm going to put in a i might have time into two l e d s and if i do i want to use that space for that sum to move this over by the batteries so let's just do that because i want to just use some or put it over here by the battery in it's not in the circuit it's just on the circuit board everything has to be connected it's not connected to anything so first thing to do is going to move the black wire and we're going to put it in the middle here because what's missing right it's open circuit it's not connected because i disconnected this wire from the negative and the l e d so i just but the white y here switch between the two things and that should be a little easier for us if we do that so what called one of you that i think i'm going to use not i wasn't here with these here i would actually play a little bit with them the simple circuit that you first built without puttin on the breadboard and that's always the first thing it's kind of fun they like it and it's actually good for adult to just take l e d m e a battery right the battery has so that basically tells you what color you are you so willing is red now pretty and that's an easy way of showing i'm just a basic circuit because you have positive test positive negative and discord around ok so i'm to put this here and i'll put this on the enemy go down three and do positive on the read down which is on the other side is probably the say seventeen sixteen fifteen to thirteen pro right so we want to do this where we can switch between the two so what do we want to do think about that for a few minutes how do we want to do this now we know we want to connect this up and what i do  i went over how the bible works and with you too and now we want to connect the l e d so i'm going to have some of my kids which is great who are going to go ahead and they're going to connected because they understand and some they do not so when i'm doing this class sometimes we add a switch sometimes we don't but i always have this which is because i'm going to have some kids in my class who just pick it up quicker and i want to challenge them and the way i challenge them is by ad what i'm going to do is i'm actually going to now try to add this so i can do there's two ways i can actually come here with the positive and i can go positive positive right and we know the positive isn't the for us one here space over here and there is a little obsessed guys i'm playing around there's a little space here this little hole not much of a hole but a little lives in it i could use that and try to see back and just do this with out the switch and i think that's what i did with my but you guys before we just did it without the switch i'm actually using just put this over here now both for the mat lighting up because of probably the drain my battery my batteries is supposed to be three votes i don't really measure in the see if they were it's really the potential way but the out and where would i put it now if i was like a kid i would just leave it like this have it any and everybody think about where should i put it now you know the switch only has one pole left to use so you probably would know which pole to basics you know we hates that when i do it but i think it's the best thing always to do well back to the basics the basics are this right i'm going to just build it again really quickly to make sure everything's good no problem up my alley no problem with my i l e d this blue can see you know if you look in it you could see it not sure i think that's a new battery i have but i reuse batteries by can little differently but that's easy it's not a big deal and i put this in the other is three homes put it at the at home and then you take it
