Mix it up!
This category of items, such as a pile containing various types of gourds and pumpkins, consists of two or more different materials physically combined.
What is a mixture of solids?
When a solid dissolves into a liquid, it breaks down and becomes this.
What is part of the liquid?
Adding heat to a sugar cube or placing it in water that is at this temperature will make it dissolve fastest.
What is boiling (or hot)?
This term describes what happens when light travels completely through a substance or object.
What is transmission (or refraction/refraction-related property depending on context)?
What is Clawd?
Small gold coins and larger silver coins can easily be separated using this physical property.
What is size (or particle size)?
When Ethan stirred salt and pepper in a pot of water, the pepper remained visible while the salt disappeared because pepper has this property.
What is insoluble?
Melting ice cubes is an example of this type of change, where no new substance is formed.
What is a physical change?
When marshmallows are dropped into hot chocolate, they warm up because they undergo this process regarding heat energy.
What is gaining heat (or absorbing heat energy)?
Plastic tape, rubber, and cotton clothing can all wrap copper wires to prevent shock because they act as these.
What are insulators?
If you want to separate a mixture of sand and rice using a colander, you are relying on this observable property.
What is particle size?
Unlike sand, which settles at the bottom of a glass, sugar is known to be this in water.
What is soluble?
Bicycles left outside during the summer rust faster because an increase in this factor speeds up the chemical process.
What is temperature (or heat)?
When floating logs are pushed downstream, this substance is supplying the energy causing their motion.
What is flowing water?
In a ceiling fan, the motor transforms electrical energy directly into this type of energy.
What is energy of motion (or mechanical energy)?
To validate the results of a scientific investigation on solubility, scientists must conduct more than this number of trials.
What is one trial?
Doing this to a mixture increases the rate of dissolving, while stopping it slows the process down.
What is stirring?
While the addition of heat causes evaporation and melting, these two phase changes occur when heat is removed.
What are freezing and condensation?
A girl holding a bowling ball represents stored energy, but a rolling ball scattering pins is a clear example of energy doing this.
What is causing motion?
Unlike wood or rubber, a gold necklace allows electricity to flow easily through it, making it one of these.
What is a conductor?
This error occurs when different scientists following the same procedure get inconsistent results.
What is a lack of reliability?
Breaking a solute into smaller pieces increases this property, causing it to dissolve much faster.
What is surface area?
Rusting metal, rotting fruit, and burning wood are all examples of this type of change, unlike melting ice.
What is a chemical change?
Kitchen appliances like toasters and ovens transform this type of energy into heat energy to cook food.
What is electrical energy?
This is Ms. Becky's favorite color.
What is purple?
