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).

You can also use a plastic bottle cap.

Past perfect

Yesterday we started to learn about the past perfect tense in English. We use it to talk about two events that happened at different times in the past.

The form is:

had + past participle

Here is the presentation we watched in class:

Past perfect from Kathleen Marcy

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:

Gaudí and his "trencadís" style

Antoni Gaudí was a Spanish artist and architect who lived and worked in the 19th and 20th centuries (he was born in 1852 and died in 1926.)  One of the techniques he used was "trencadís"-- a mosaic form using broken ceramic tiles to add colour and shapes to a design.

Here are some examples of his work:


A lizard from Parque Guell in Barcelona




Benches in Parque Guell

We are going to take inspriration from this technique for our next art project!
