In an experiment, you water two groups of plants with different amounts of water. You measure the height of the plants every week. What is the independent variable, and what is the dependent variable?


Answer:

  • Independent variable: Amount of water (because you are changing it to see its effect)
  • Dependent variable: Height of the plants (because it depends on the amount of water)

Question:
You conduct an experiment where you test how different types of fertilizer affect the growth of tomato plants. You use three types of fertilizer and measure how many tomatoes each plant produces. What is the independent variable, and what is the dependent variable?


Answer:

  • Independent variable: Type of fertilizer (because you're changing the type to see its effect)
  • Dependent variable: Number of tomatoes produced (because this depends on the type of fertilizer used)

Question:
What is the main gas that makes up the Earth's atmosphere?


Answer:

  • Nitrogen
    (Nitrogen makes up about 78% of the Earth's atmosphere.)

OPINIONS

Why isn't the question 'Why do we dream?' a testable question?


No data to be collected

No hypothesis can be created to test a theory

No observation can be made

etc.

Question:
In a study, you want to find out if the temperature of a room affects how long students can concentrate on their homework. You test this by varying the room temperature (cold, warm, hot) and measuring how long the students can focus. What is the independent variable, and what is the dependent variable?


Answer:

  • Independent variable: Room temperature (because you're changing it to observe its effect)
  • Dependent variable: Time spent concentrating (because this depends on the room temperature)
300

Question:
What causes day and night on Earth?


Answer:

  • The rotation of the Earth on its axis
    (Earth spins on its axis, and when a part of the Earth faces the Sun, it’s day; when it faces away from the Sun, it’s night.)

Which of the 5 senses would you aim to be using to make a scientific observation?

You need to use all of your senses when making observations, and adapt based on the situation. 

(However in our lessons we have been mostly using sight)

True or False:

"The statement 'The government should invest more in renewable energy sources to combat climate change' is a fact."

FALSE, this is an opinion

This is an opinion because it expresses a belief or recommendation about what the government should do. While it may be based on scientific data and arguments, it is not an objective, verifiable fact. Facts are statements that can be proven true or false through evidence, while opinions are subjective perspectives.

400

"What is the exact temperature at which the Earth will become uninhabitable?"

Testable or not testable?

Non-testable 

because it concerns a measurable physical phenomenon (temperature), the idea of determining a precise temperature at which Earth becomes "uninhabitable" oversimplifies the complexity of environmental and biological systems, making it ultimately non-testable. 

TOO SUBJECTIVE

Question:
You are testing the effect of different amounts of screen time on how well students do on a math quiz. You give students 0, 30, and 60 minutes of screen time before the quiz and then measure their quiz scores. What is the independent variable, and what is the dependent variable?


Answer:

  • Independent variable: Amount of screen time (because you're changing it to see how it affects the quiz scores)
  • Dependent variable: Math quiz scores (because the scores depend on the amount of screen time)
400

Question:
What is the name of the process by which plants release water vapor into the atmosphere through their leaves?


Answer:

  • Transpiration
    (Transpiration is the process through which water is absorbed by roots, moves through plants, and is released as water vapor from small pores in the leaves called stomata.)

Why are scientific observations important for the inquiry cycle/ scientific method?

They are the first step of the inquiry cycle - they help us to form questions and hypothesis before testing a theory

500

What is the definition of a scientific fact?

A scientific fact is an observation or measurement that has been repeatedly confirmed through evidence and is accepted as true under specific conditions. 

It is a piece of information that is objective, verifiable, and remains consistent across time and various experiments or observations

Name 2 components of what makes a solid  TESTABLE question.

  • Variable: The amount of sunlight (independent variable) can be controlled and measured.
  • Measurement: The growth rate of the tomato plants (dependent variable) can be measured, typically by height, number of leaves, or fruit production.
  • Experimentation: You can conduct an experiment where one group of tomato plants gets more sunlight than another, and you can observe how the growth rates differ.

In a science experiment, you want to test how different colors of light affect the growth of plants. You expose one group of plants to red light, another group to blue light, and a third group to white light. You measure the amount of plant growth after two weeks. What is the independent variable, and what is the dependent variable?


Answer:

  • Independent variable: Color of the light (because you are changing it to observe its effect on plant growth)
  • Dependent variable: Amount of plant growth (because growth depends on the color of light)

What is the primary difference between vertebrates and invertebrates?


Answer:

  • Vertebrates have a backbone or spine, while invertebrates do not have a backbone.
    (Examples of vertebrates include mammals, birds, reptiles, amphibians, and fish. Examples of invertebrates include insects, spiders, and worms.)
