Resources to help you study about Magnetism and Electricity

Our test is coming up on Thursday. Here are some resources to help you study!

In this presentation, look at slides 1-18:

Conductors and insulators from Mr. M



Electrical Conductors And Insulators from xnpsp5


Finally, a slideshow with everything you need to know for the test!

Electricity and magnetism from Kathleen Marcy

An extra credit project

Extra credit activity for Natural Science:

For an extra point on your exam, you can do one extra credit activity.

1)  Make your own compass

--Watch the video on the blog

http://5thgrademiguelhernandez.blogspot.com.es/2016/11/make-your-own-compass.html

--Make your own compass

--Take a digital photo or video

--Explain how it works. (video or written)

--If you don’t have a camera, you can draw a picture of the compass and label the parts. Write your explanation.

2)  Magnetic or not?

--Find 15 objects and test whether or not they are magnetic. At least 10 of them must be made of metal. You can use different coins.

--Make a video (optional—not necessary)

--Make a chart: 

Name of object	What is it made of?	Is it magnetic?
USA quarter (25 cent coin)	Mostly copper
spoon	steel

Write a conclusion: Objects made of ………………………….. are magnetic. Examples:

• You must hand in the activity on or before Thursday, 17^th November.
• Your written work must be neat and with good presentation.
• You may work individually or with a partner (three people maximum).
• If you make a video or take digital pictures, you can send your project to me by email at:

A science experiment!

We are going to do an experiment on Friday-- we are going to create electromagnets!  For the experiment you will need:

--a battery (pila de petaca):

  or   




--50-100 cm of insulated cable 

--a long iron nail

--metal paper clips

You can read about the experiment on page 76 of your book.

Here is a picture:

A joke for you!

Here is Tesla's power plant at Niagara Falls:




The falls:




 Closer to us, we have some hydroelectric power stations, too. You can click here to read about one at the "Cascada del Ézaro" in Galicia where they now have a "Museum of Electricity."



Even closer to us, in La Alcarria, Guadalajara, at Sacedón:





Have you ever seen a hydroelectric power plant?

More circuits

Can you label the parts of this circuit?  What type of circuit is it?

Here is a diagram of the circuit:

How do we use electricity?

Electricity is generated in power stations. Here is a solar power station in Seville.  It uses the Sun's thermal energy to produce steam, which is used to power turbines to generate electricity.






Here is a Nuclear Power Station in Guadalajara:





From the power station, the electricity travels along big cables to our homes.  Pylons help keep these cables away from people and things on the ground.





Where the electricity enters our house, there is a fuse box. This makes the electricity safe to use.






From the fuse box, the electricity travels through wires to all the light switches and sockets in our home.

Circuits and symbols

We are learning about electrical circuits. 



Making circuits:



Here's a game about making circuits.

Let's try this one!

And here:

Electricity song!

Since I know how much you like singing, here is a song about electricity, our next topic in Natural Science. I listened to it when I was a child, so it is an old song, but the tune is very catchy (pegajoso)!




Here are some explanations:

Static Electricity experiment

Watch this!

Static electricity is the movement of electrons between two materials.

Opposite charges attract each other.

Objects with the same electric charge are repelled.

Rubbing the balloon gives it a negative charge. Electrons move from your hair to the balloon.  Your hair loses electrons and becomes positively charged. 

    Opposite charges attract each other.  The balloon (negative)   attracts your hair (positive).

    Each hair has a positive charge. The hairs repel each other (they separate).


Now, look at this explanation of how static electricity is used to paint cars: 

What is an atom?

 All matter is made up of microscopic particles called molecules. We can divide a molecule into smaller parts, called atoms. An atom is the smallest part possible-- it cannot be divided.  In fact, the word "atom" in Greek means "indivisible."





Electricity is formed when electrons move from one atom to another.
