100

A scientific guess, prediction or explanation

What is a hypothesis?

100

These objects have a definite shape and volume, characterized by closely packed particles (atoms, molecules, or ions) held together by strong forces, allowing them to vibrate but not move freely 

What is a solid?

100

This is a physical combination of two or more substances (elements or compounds) where each substance keeps its own chemical identity and properties

What is a mixture

100

This is a process where substances transform into new material when combined.

What is a chemical reaction?

100

a lipped cylindrical glass container for laboratory use

What is a beaker?

200

The term for any factor, trait, or condition that can change or be changed in an experiment. 

What is a variable?

200

This state of matter has no fixed shape or volume, characterized by widely spaced, rapidly moving particles that expand to completely fill their container 

What is a gas?

200

This is a homogeneous mixture where one substance (the solid) is completely dissolved in another (the liquid), creating a uniform composition where particles are evenly distributed.  

What is a solution?

200

This type of change alters a substance's form or appearance (like shape, size, or state) without changing its fundamental chemical identity. 

What is a physical change?

200

This is a precise tool for measuring mass by comparing an unknown quantity to known weights

What is a balance?

300

This is the part of your science experiment that stays the same and allows you to compare your results to the part of your science lab that you changed.

What is a control?

300

This state of matter has a definite volume but no fixed shape, meaning it takes the shape of its container while keeping a constant volume.

What is a liquid?

300

This is a physical separation process that removes solid particles from a liquid or gas by passing the mixture through a porous filter medium that traps the solids while letting the fluid pass through, relying on differences in particle size.

What is filtering?

300

This is the measure of how much of a substance (solute) is mixed into a specific amount (volume or mass) of another substance (solvent or total solution), essentially indicating the solution's "strength" or "richness". This solution might be stronger or darker when compared to other similar solutions.

What is concentrated?

300

This is a scientific tool that measures temperature (how hot or cold something is) by detecting physical changes in a substance

What is a thermometer?

400

These are the facts, figures, observations, or measurements collected for analysis, forming the evidence to test hypotheses.

What is data?

400

This is the term for when a gas becomes a liquid.

What is condensation?

400

This is the name for the substance that gets dissolved in another substance to make a solution.

What is a solute?

400

This action is to decrease the concentration of a solution, typically by adding more solvent (like water), making it weaker or less pure, without adding more of the dissolved substance (solute). A solution like this might look lighter or weaker than other similar solutions.

What is diluted?

400

This is a place where scientists write down their records, ideas, data and conclusions about experiments.

What is a science notebook?

500

This is what it is called when you study an object and record information within your experiment.

What is Observation?

500

This is the term for when a solid becomes a liquid

What is melting?

500

This is the name of a substance, typically a liquid, that dissolves another substance to create a solution.

What is a solvent?

500

This is one property of objects related to mass. Because of the mass of these objects, one object might sit or float on top of another. For example, why does whipped cream float on hot cocoa or a balloon float in the air.

What is density?

500

a precision tool with a barrel, plunger, and nozzle (often a needle) used to accurately measure, inject, or withdraw precise volumes of liquids in laboratory settings for tasks like mixing, diluting, extracting samples, or delivering reagents

What is a syringe
