🧪 Properties of Matter
This describes whether something can be attracted to a magnet.
What is magnetism?
A toaster turns electrical energy into this type of energy.
What is thermal (heat) energy?
This is what happens when light bounces off a surface.
What is reflection?
This landform forms where a river drops sediment into the ocean.
What is a delta?
Living things in an environment are called what?
What are biotic factors?
his property tells whether an object will sink or float in water.
What is relative density?
A flashlight changes battery (chemical) energy into these two forms of energy.
What is electrical and light energy?
This is the bending of light, like when it passes through water.
What is refraction?
This deep valley with steep sides is carved by a river (fast-moving water) over time.
What is a canyon?
This is the place where an organism lives and can find everything it needs to survive.
What is a habitat?
You mix sugar into water and it disappears. What property is this?
What is solubility?
What energy transformation happens when a person eats and runs?
Hint: Food stores chemical energy.
What is chemical energy to mechanical energy?
This happens when light is taken in by a material like black fabric.
What is absorption?
This landform looks like a rock split in two and is found in New Zealand.
What is Split Apple Rock? .
A mushroom breaking down a log is what type of organism?
What is a decomposer?
A metal spoon feels colder than a wooden spoon. Why?
What is thermal conductivity?
A radio turns electrical energy into what two forms?
What is sound and light energy?
Why can’t you see through a wooden door?
Hint: transparent, translucent and opaque.
What is because it is opaque and blocks light?
This landform is formed by glaciers.
What is a U-shaped valley?
If a predator disappears, what happens to its prey population?
What is it may increase?
Compare the physical state, magnetism, and conductivity of a metal paperclip and a wooden toothpick.
What is the paperclip is solid, magnetic, and conducts electricity; the toothpick is solid, not magnetic, and does not conduct electricity?
Explain the energy transformations in a solar panel powering a fan.
What is solar energy changes into electrical energy, then into mechanical energy?
Explain how sunglasses help your eyes in the sun using what you know about light.
What is sunglasses absorb some light to reduce glare and protect your eyes from bright sunlight?
Compare how a canyon and U-shaped valley are formed.
What is a canyon is formed by rivers cutting into rock; a U-shaped valley is formed by glaciers carving through rock?
Make a claim about how water and shelter affect organisms in a habitat.
What is if water or shelter are missing, organisms may not survive or could move to another habitat?
