This video introduces Caroline Herschel and her brother William. Caroline talks about their work studying the planets and the solar system, and shares her astronomical discoveries, including comets and nebulae. She also explains how she was the first woman to discover a comet, which was subsequently named after her, 35 P Herschel-Rigollet. William talks about how he discovered the planet Uranus. After being made an assistant to her brother, Caroline Herschel was the first woman to be paid for scientific work. She made many observations and found 2,500 nebulae, summarized in a list called the Catalogue of Nebulae and Clusters of Stars – abbreviated to CN. She recorded her findings precisely by drawing the nebulae. Teacher notes: As a starter to introduce a practical science activity, you could write a simple quiz to encourage students to capture the keywords shown in the video. Students can write their own definitions from these words using the internet or science dictionaries to improve their scientific vocabularies. To consolidate their knowledge, you could get students to make booklets that include key information about the work of Caroline and William Herschel. They could define the keywords featured in the video, and find five or more additional pieces of information about the work of the scientists using books, encyclopedias or the internet.
