Unit 1 Nature of Science: Concepts

Dominic and Isabella are in the science lab. Can you help them find the tool that protects their eyes?

• Goggles

• Beaker

• Graduated Cylinder

• Telescope

Answer explanation

Goggles are specifically designed to protect your eyes from harmful substances and debris, making them the correct choice for eye protection in scientific settings. Other options like beakers and graduated cylinders are not protective gear.

Tyler and Aria are on a quest to find information on the internet. Which science tool should they use?

• Goggles

• Computer

• Beaker

• Graduated Cylinder

Answer explanation

The correct answer is 'Computer' because it is the tool used to access and look up information on the internet. Goggles, beakers, and graduated cylinders are scientific tools but not used for internet searches.

Isabella and Scarlett are on a stargazing adventure! Which science tool would they use to look into space and view planets?

• Goggles

• Beaker

• Graduated Cylinder

• Telescope

Answer explanation

A telescope is the correct tool for viewing planets in space, as it is specifically designed to magnify distant objects. Goggles, beakers, and graduated cylinders are not used for astronomical observations.

Ivan and Alexa are in the science lab. They need to find the mass of an object for their experiment. Which tool should they use?

• thermometer

• Balance

• Telescope

• Graduated Cylinder

Answer explanation

A balance is a scientific tool specifically designed to measure the mass of an object. Unlike a thermometer, which measures temperature, or a graduated cylinder, which measures volume, a balance provides accurate mass readings.

Landon and Tia are in the science lab. They need to find the temperature of a mysterious liquid. Which tool should they use?

• Graduated Cylinder

• Thermometer

• Graduated Cylinder

• Computer

Answer explanation

The correct tool for measuring the temperature of an object is a thermometer. A graduated cylinder is used for measuring liquid volume, while a computer does not measure temperature directly.

Dominic and Alyssa are in a science class. They need to find the length of an object. Which tool should they use?

• Graduated Cylinder

• Computer

• Thermometer

• Ruler

Answer explanation

A ruler is a science tool specifically designed to measure the length of objects accurately, making it the correct choice. A graduated cylinder measures volume, a computer is for processing data, and a thermometer measures temperature.

Mia and Lincoln are curious about the tiny world of cells. Which science tool should they use to observe these small wonders?

• Hand Lens

• Telescope

• Microscope

• Proscope

Answer explanation

The correct answer is 'Microscope' because it is specifically designed to observe cells and other small objects at high magnification, unlike a hand lens, telescope, or proscope which serve different purposes.

Imagine Timmy and Avery are setting up a science experiment. What do they start with?

• Hypothesis

• Theory

• Question

• Procedure

Answer explanation

A science experiment begins with a question, which identifies what the researcher wants to investigate. This question guides the development of a hypothesis and the overall experimental design.

John and Isabella are playing with their toy cars. What type of model is a toy car?

• 2-D

• 3-D

Answer explanation

A toy car is a physical object that has three dimensions: length, width, and height. Therefore, it is classified as a 3-D model, not a 2-D representation, which would only have length and width.

Lylah and Timmy are looking at a map. What type of model is a: Map

• 2-D

• 3-D

Answer explanation

A map is a representation of geographical areas and features on a flat surface, which makes it a 2-D model. Unlike 3-D models that depict depth and volume, maps only show length and width.
