6th Grade Science Supports

Vocabulary Wall:

  • Observation- what I see, taste, touch, smell, hear
  • Inference- what I guess, assume
  • Prediction- a future statement with words like, “will,” “might,” “could” etc
  • Hypothesis Statement- If (inference), then (prediction)
    • Ex: If the grass needs light to grow, then grass in the shade will not grow well.
  • Independent Variable- what I choose/change in my experiment
    • Ex: The amount of light I expose the grass to
  • Dependent Variable- what I measure at the end of my experiment
    • Ex: The growth of the grass
  • Controlled Variable- what I keep consistent in my experiment
    • Ex: The type of grass, the amount of time since it was planted, the watering schedule
  • Bias- my preferences that cause unfair/inaccurate results


  • Light- information for our eyes (without light traveling from objects to our eyes, we can’t see)
  • Reflection- when light bounces off of a surface (not just a mirror, but any object!)
  • Concave Mirror- a mirror that curves inward (like a cave). When light hits a concave mirror, there is a focal point and the reflection is upside down.
  • Convex Mirror- a mirror that curves outward. When light hits a convex mirror, there is no focal point and the reflection is right side up.
  • Focal Point- a point where light beams cross, causing the image to be upside down
  • Photon- Energy particle of light
  • Electromagnetic Wave- The spectrum of all light (visible and invisible)
  • Wave Height- How tall a wave is
  • Amplitude- How tall a wave is (from the middle to the top)
  • Frequency- How spread out a wave is/ how scrunched up it is (also, how fast it is traveling) 
  • Thermal Energy- How much heat energy a particle has (high T.E. is HOT!)
  • Kinetic Energy- How much motion a particle has (high K.E. is moving a lot!)
  • Atom- Smallest particle of matter
  • Molecule- More than one atom stuck together with a chemical bond
  • Crystal- Repeating pattern of atoms stuck together with chemical bonds
  • Conduction- When particles hit each other, causing energy to transfer
  • Convection- When hot particles float up and cold particles sink down
  • Radiation- When electromagnetic waves (like sunlight) are absorbed by a particle
  • Condensation- Particles of gas cool down, get denser, and become liquid
  • Evaporation- Particles of liquid get warmer, get less dense, and become gas
  • Density- how much stuff in some space (high density= lots of stuff in a little space, low density= not much stuff in the space)

Step 1: Radiation- Sun warms the Earth’s ground particles

Step 2: Conduction- The Earth’s particles warm the air particles
