Transmitting database data to view won't work

Hello everyone

I am following the CI tutorials and it works well when I use the news.php controller as stated in the tutorials. However I get errors trying to transmit model data to my static pages(pages.php controller and home.php) I had made earlier.here are the errors:
...............................................................
A PHP Error was encountered

Severity: Notice

Message: Undefined variable: news

Filename: pages/home.php

Line Number: 1
........................
A PHP Error was encountered

Severity: Warning

Message: Invalid argument supplied for foreach()

Filename: pages/home.php

Line Number: 1
............................................................
This is my code for

news_model.php
<?php
class News_model extends CI_Model {

public function __construct()
{
$this->load->database();
}


public function get_news($slug = FALSE)
{
if ($slug === FALSE)
{
$query = $this->db->get('news');
return $query->result_array();
}

$query = $this->db->get_where('news', array('slug' => $slug));
return $query->row_array();
}


}

Then for News.php controller

<?php

class News extends CI_Controller {

public function __construct() {
parent::__construct();
$this->load->model('news_model');
}


public function index() {
$data['news'] = $this->news_model->get_news();
$data['title'] = 'News archive';

$this->load->view('templates/header', $data);
$this->load->view('news/index', $data);
$this->load->view('templates/footer');
}

public function view($slug) {
$data['news_item'] = $this->news_model->get_news($slug);
if(empty($data['news_item'])) {
show_404();
}

$data['title'] = $data['news_item']['title'];

}

}

Here comes index.php for view

<?php foreach ($news as $news_item): ?>

<h2><?php echo $news_item['title'] ?></h2>
<div id="main">
<?php echo $news_item['text'] ?>
</div>
<p><a href="news/<?php echo $news_item['slug'] ?>">View article</a></p>

<?php endforeach ?>

AND this view.php

<?php
echo '<h2>'.$news_item['title'].'</h2>';
echo $news_item['text'];

THE STATIC PAGES ARE:
pages.php
<?php

class Pages extends CI_Controller {

public function index()
{
$data['news'] = $this->news_model->get_news();
$data['title'] = 'News archive';

$this->load->view('templates/header', $data);
$this->load->view('pages', $data);
$this->load->view('templates/footer');
}

public function view($page = 'home')
{
if ( ! file_exists(APPPATH.'/views/pages/'.$page.'.php'))
{
// Whoops, we don't have a page for that!
show_404();
}

$data['title'] = ucfirst($page); // Capitalize the first letter

$this->load->view('templates/header', $data);
$this->load->view('pages/'.$page, $data);
$this->load->view('templates/footer', $data);
}
}

AND HOME home.php
<?php foreach ($news as $news_item): ?>

<h2><?php echo $news_item['title'] ?></h2>
<div class="main">
<?php echo $news_item['text'] ?>
</div>

<?php endforeach ?>

Thanks for your help
