(Science Trek music) JOAN CARTAN-HANSEN, HOST: How do we make Science Trek? Months before a new school year starts, I start doing research. I talk with teachers, scientists, and do more reading. We pick the topics for the season and then I write and find our guest scientists and write and write and write some more. We also collect questions from students for the blog. Next, we interview our scientists and do our filming. If needed, we film the kid actors who appear in our video shorts. Cassandra, who is our graphic artist, works on all the animations and words you see on the screen. Cassandra: Hi CARTAN-HANSEN: We record my voice for the set-up pieces and promos. Then Jenessa, our director, starts editing. She also edits all the other visual elements, sound effects and music. She also adds the close captioning. Logan edits the podcasts. It takes the team about three weeks to put everything together. The folks in traffic get the show into the system. And the folks in master control puts the show on the air. And no television show happens without the engineers, The communication staff, the accountants, the administrative staff, the development staff, the web folks, and all the production staff. So, you see, it takes a lot of people, with lots of different skills, a lot of time to make Science Trek. For more information about television, check out the Science Trek website.
