2. Work out and explain the differences between an atom , a molecule , a radical and an ion . Give examples from the Molecules in space table. Collecting data: practical techniques Find out how the molecules in the Molecules in space table are detected. Describe this in your experimental procedures section. Questions 1. How can such tiny molecules be detected from so far away? 2. How do we know that the signals are from a particular molecule? 3. What molecules would need to be detected to show there is life elsewhere? Making conclusions Research how molecules form in space. Try typing How do molecules form in space? in a search engine. See if you can work out how and where molecules form. Questions 1. Explain why there are more molecules with smaller numbers of atoms. 2. To make life, large molecules called polymers are needed. Molecules with double and triple bonds can form polymers. List these from the Molecules in space table. 3. Look at the largest molecules in the Molecules in space table. Could these make life? 4. What other experiments could be done to find out if there is life elsewhere in space?

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
