Whether you want to know whether penguins have knees or what a black hole is, Science Line has the answer. The service - on 0808 800 4000, Monday to Saturday, 1-7pm - is open to everyone, but as part of Science Year 20012, will particularly focus on helping 10 to 19-year-olds still deciding on their careers and options. The Science Line team has also developed outreach activities such as a murder mystery show, an archaeology show and illustrated talks. Interested teachers should contact the team, tel: 020 8735 5015.
