Preview physical science concepts: forces, pressure, states of matter, and chemical classification.
Relating air pressure to weather
A tiny difference in air pressure can give you a gentle breeze, but a massive difference can spawn a powerful cyclone! Forces and pressure shape the weather that affects our daily lives.
Explanation of forces and electricity.
Forces are what make objects speed up, slow down, or change direction.
Understanding forces helps explain why a ball thrown up in the air falls back down to the ground, or why a speeding car stops when the brakes are applied.
Explanation of particles and matter classification.
Everything around us is made of tiny particles. The way these particles behave determines the physical state of the material.
In solid materials, these particles cannot move much and hold their shape tightly. In gases, they are spread out and can move around freely.
Visual comparison of elements, compounds, and mixtures.
Flashcards for matter classifications.
Matching exercise for physical and chemical properties.
