Tags won’t show in complex page template

I have a page in which the page content appears at top, followed by a category query which returns the one most recent post and then the titles of all posts in that category. I want to show the tags in the posts and below the titles, but the_tags() is not working for some reason.

here’s my code

<?php

/*

Template Name: Lessons and Activities Page

*/

?>

<?php get_header(); ?>

<?php get_sidebar(); ?>

<div id="content">

    <?php if (have_posts()) : while (have_posts()) : the_post(); ?>

	<div class="post" id="post-<?php the_ID(); ?>">

		<h2><?php the_title(); ?></h2>

		<div class="entry">

		<?php the_content('<p>Continue reading &raquo;</p>'); ?>

	 <?php endwhile; endif; ?>

<!--get latest Lessons and Activities post-->

<h3>Recently Added </h3>

  <?php $my_query = new WP_Query('category_name=lessons&showposts=1');

  while ($my_query->have_posts()) : $my_query->the_post();?>

	<h2><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title(); ?>">

    <?php the_title(); ?></a></h2><small><?php the_time('F jS, Y') ?> <?php the_tags('| Topic: ', ', ', '.') ?></small>

			<?php echo the_content(); ?> 

				  <?php endwhile; ?>

<!--get all archived Lessons and Activities posts-->

<h3>All Lessons and Activities</h3>

  <?php $my_query = new WP_Query('category_name=lessons');

  while ($my_query->have_posts()) : $my_query->the_post();

  $do_not_duplicate = $post->ID; ?>

    <!-- Do stuff... -->

	<h3><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title(); ?>">

    <?php the_title(); ?></a></h3><small><?php the_time('F jS, Y') ?> <?php the_tags('| Topic: ', ', ', '.') ?></small>

  <?php endwhile; ?>
