The most recent Academy of Science and Technology blog carnival is up at Kim's Play Place. Be sure to take a look for new ideas for science activities. As the submission page says, "This is a carnival to share great ideas for kids in science and technology--at home projects, teaching in class, teaching at home or any other way kids and adults can explore, discover, and make together."
I will be hosting the carnival on April 13, so if you have a relevant post you would like to share, be sure to submit it via the carnival submission form. It isn't hard, it just takes a minute. Can't wait to see what fun science you have posted on your blogs.
