The Get to Work Expansion Pack for The Sims 4 unlocks a world of possibilities for ambitious Sims. The intriguing scientist career is among these, and it is perfect for knowledge seekers and aspiring inventors.

As a Scientist, your Sim will spend their days at the high-tech FutureSim Labs. They’ll tackle various tasks here, from concocting serums with strange effects to inventing groundbreaking gadgets. Success in this career hinges on both technical skills and social connections. Building rapport with colleagues allows you to delegate tasks, accelerating your progress.

This guide details all the necessary information to navigate the exciting world of scientific research in The Sims 4 and make sure your Sim unlocks its full scientific potential.

How to Become a Scientist in The Sims 4?

If you want to take a Scientist career in The Sims 4, go to the Career Panel in the bottom right corner and choose Scientist from the list of options.

You will get the job of a Lab Technician, which will be a 10 AM – 7 PM job giving you $24/hour for 5 days a week (Monday – Friday). Your job here will require you to make new inventions and serums, which will require materials to make, like crystals, elements, and even plants. So, it’s good to stock up on these collectibles early.

For plants, it’s good to buy some starter seeds; as for materials and crystals, you can get them from digging the sites around the workplace. Or you can ask your co-worker to give you crystal, metal, or DNA samples. Also, you may get more collectibles by analyzing crystals or metals on a chemical analyzer, and when you create a new serum, it levels up your career.

Keep looking at the bar for tasks and complete them to increase your level. After reaching higher levels in this career and unlocking career rewards, you get a chance to get to Sixam, which is an alien world using a spaceship. You can make money manufacturing items using SimRay.

Best Skills and Traits to choose


If you want your sim to become a scientist, you must first investigate the logic skill. Because in this career, there is no perfect path to level up in this career, so you need logical skills to make new inventions and solve different analytical problems.


The tasks you will be doing require a lot of brain processing, so genius is also a must-skill in your sim. If you are a scientist, you need many Eureka moments to be inspired by your inventions.


Sometimes, you must work for weeks before inventing anything new as a scientist, so you must be a geek enough to excel in this career. More than the other two professions, scientists depend extensively on their goals lists, so you must be a geek to complete these goals.

Career Tasks

You will get multiple tasks during your career as a scientist in Sims 4, divided into either inventing a serum or making a breakthrough invention. You will have to make 6 inventions and 15 serums throughout your career. As for the serums are created in the chemistry lab using your Scientist Notebook, and as said above, serums are made using plants. Whereas for inventions, you need materials. Let’s go through all the inventions and materials needed to make them:

InventionMaterials Needed
Momentum CoserverNo materials needed
Hover LampNo materials needed
Cloning MachineCommon Metal (x2), Common Crystal (x2)
Satellite DishCommon Metal (x3), Common Crystal (x3)
SimRayCommon Metal (x1), Common Crystal (x1)
Electroflux Wormhole GeneratorUncommon Metal (x2), Uncommon Crystal (x2), Element (any)

How to have Breakthroughs

Breakthroughs are important to get promoted; they are essentially the promotion task of this active career, and thankfully, they are very easy to get. You can get them while having a shower, reading a book, or running on a treadmill; there are so many ways you won’t have any issues achieving this. In short, you can get them from everyday interactions. This means you can easily turn this career into a passive career if you want to snap up promotions.

Unlockable Inventions and Serums

After the first six levels, you can unlock new inventions; these inventions help boost your sim moodlets and earn them some extra income. Therefore, it is important to create these inventions to maximize the benefit of the career, but most importantly, you need materials to create them. These materials can be either metals or crystals, which are rare and don’t require money to purchase.

5Cloning MachineCommon Crystal (2) Common Metals (2)Clones’ different objects and even simsLevel 8 – allows the cloning of Sims, however the cloned sim will not possess the same trait, career, or skills
6Electroflux Wormhole GeneratorUncommon Crystal (2) Uncommon Metals (2) Elements (2)It allows focused moodlets and more breakthroughsLevel 10 – When you upgrade the device, it allows sim to travel to Sixam (a hidden area)

Other than inventions, serums are also valuable as they allow you to earn money without spending anything in the Sims 4 Scientist Career. Once you craft a serum, you can gift it to other sims. Serums can be exercised to be used in either a good or bad way. However, you must not overuse them; wait for the effects of one serum to wear off, and then use another. There are 15 serums in total that you can craft. Let’s go over them all:
