What is Science?
The systematic study of the natural world through observation and experimentation.
Science encompasses various fields such as biology, chemistry, physics, and earth science.
What are the different types of Science?
Major branches of science include:
* Natural Sciences
* Formal Sciences
* Social Sciences
* Applied Sciences.
Each branch focuses on different aspects of knowledge and inquiry.
What are some common Science Careers?
Examples of science careers include:
* Biologist
* Chemist
* Physicist
* Environmental Scientist.
Careers in science often require specialized education and training.
What are Science Lab Rules?
Basic science lab rules include:
* Wear safety goggles
* No food or drink
* Follow instructions carefully
* Keep workspace clean.
These rules help ensure safety and proper conduct in the lab.
What is a Bunsen Burner?
A laboratory device used to produce a single open gas flame.
It is commonly used for heating, sterilization, and combustion in labs.
How do you use a Bunsen Burner?
Steps to use a Bunsen burner include:
* Connect to gas supply
* Adjust air intake
* Light with a striker
* Adjust flame height.
Always follow safety protocols when using a Bunsen burner.
What is the aim of a scientific report?
A clear statement of the purpose of the experiment.
The aim guides the direction of the research and experimentation.
How do you write a hypothesis?
A hypothesis is written as a testable statement predicting the outcome of an experiment.
It often follows the format: ‘If [independent variable], then [dependent variable].’
What are the types of scientific measurement?
Types of measurement include:
* Length
* Mass
* Volume
* Temperature.
Accurate measurements are crucial for reliable scientific results.
What is a meniscus?
The curved surface of a liquid in a container, often seen in graduated cylinders.
Read the measurement at the bottom of the meniscus for accuracy.
What are variables in an experiment?
Variables are elements that can change in an experiment. Types include:
* Independent
* Dependent
* Controlled.
Understanding variables is essential for designing experiments.
What is a fair test?
An experiment where only one variable is changed at a time while others are kept constant.
This ensures that the results are due to the variable being tested.
What is the difference between Observation and Inference?
Observation is collecting data through the senses, while inference is a logical conclusion based on observations.
Both are critical in scientific methods.
What is the difference between Qualitative and Quantitative data?
Qualitative data describes characteristics, while quantitative data involves numerical measurements.
Both types of data provide valuable insights in research.
What are different types of graphs?
Common types of graphs include:
* Bar Graphs
* Line Graphs
* Pie Charts
* Histograms.
Graphs help visualize data for easier interpretation.
What does TAILS stand for in graphing?
TAILS stands for:
* Title
* Axes
* Intervals
* Labels
* Scale.
Following TAILS ensures clarity in graphical data presentation.
What does CER stand for in scientific claims?
CER stands for:
* Claim
* Evidence
* Reasoning.
This framework is used to structure scientific arguments and conclusions.
What is a ‘Can do list’ in science learning?
A list of skills and concepts that students are expected to master.
It serves as a self-assessment tool for learners.
What is an Extension in science education?
Extension refers to activities that deepen understanding or application of scientific concepts.
Extensions can enhance learning through real-world applications.
