Sun
300
Why does a lightbulb not turn on when a switch is open?
The circuit is incomplete
300

400
How does light travel?
In a straight line
400
What variables are kept the same during an experiment?
Controlled variables
500
What causes shadows to move throughout the day, and how long does this movement take to repeat?
Shadows move because Earth rotates on its axis, and this cycle repeats every 24 hours.

How are the following landforms created:
Sand Dune
U-shape Valley
Delta
Sand dune: Wind
U-shape Valley: Ice/Glacier
Delta: Water (slow moving)
500
What is the difference between weather and climate?
Weather is short term and climate is long term
500
Why does a black T-shirt feel warmer than a white T-shirt on a sunny day?
Because black absorbs more light energy, while white reflects lights most light.
