For the bobblehead in Fallout 3, see Bobblehead - Science.

Always be prepared to explain the hows and the whys.

The Science bobblehead is a a Vault-Tec bobblehead in Fallout 4. When picked up, it permanently grants one extra guess when hacking terminals.


It is found inside Malden Middle School/Vault 75, on the desk overlooking the subterranean "Diner" combat test area inside the vault building on basement level 3. You need to get the Vault 75 lab access card off the Gunner commander in the diner to get to this room. Essentially, just follow the Vault 75 side quest that starts upon entering Vault 75.
