Working Scientifically: Key Concepts and Safety

This comprehensive guide introduces fundamental scientific concepts and laboratory safety principles. The content covers essential scientific terminology, hazard awareness, and experimental variables that form the foundation of scientific investigations.

Vocabulary:

  • Data: Facts and statistics collected for reference and analysis
  • Risk: Possibility of harm or damage
  • Hazard: A danger, distinct from risk in terms of danger level
  • Variable: Any changeable factor in an investigation
  • Hypothesis: An idea based on limited evidence pending testing
  • Observation: The act of closely monitoring something
  • Accurate: Correct in all details and exact
  • Precise: Showing exactness or similar results demonstrating precision

Definition: Hazard symbols are standardized warning signs that alert people to potential dangers and promote safe laboratory practices. Two important examples include the oxidizing and irritant symbols.

Example: In scientific investigations, there are three types of variables:

  1. Independent Variable: The factor you deliberately change
  2. Dependent Variable: The factor that responds to changes in the independent variable
  3. Control Variables: Factors that must remain constant throughout the experiment

Highlight: Understanding the difference between accuracy and precision is crucial in scientific work. While accuracy refers to correctness in all details, precision relates to the consistency of results.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

Just amazing. Let's me revise 10x better, this app is a quick 10/10. I highly recommend it to anyone. I can watch and search for notes. I can save them in the subject folder. I can revise it any time when I come back. If you haven't tried this app, you're really missing out.

This app has made me feel so much more confident in my exam prep, not only through boosting my own self confidence through the features that allow you to connect with others and feel less alone, but also through the way the app itself is centred around making you feel better. It is easy to navigate, fun to use, and helpful to anyone struggling in absolutely any way.

The app's just great! All I have to do is enter the topic in the search bar and I get the response real fast. I don't have to watch 10 YouTube videos to understand something, so I'm saving my time. Highly recommended!

I know a lot of apps use fake accounts to boost their reviews but this app deserves it all. Originally I was getting 4 in my English exams and this time I got a grade 7. I didn’t even know about this app three days until the exam and it has helped A LOT. Please actually trust me and use it as I’m sure you too will see developments.
