Light, Shadows, and Sound Vibrations

Observe, compare, and sort everyday materials based on observable physical properties and practical uses.

Demonstrate the properties of air and water, including flow, taking up space, and changing between solid, liquid, and gas.

Investigate dissolving in water, explore factors that affect dissolving speed, and separate simple mixtures.

Identify everyday chemical changes and recognize indicators such as color changes, gas release, and temperature shifts.

Investigate how pushes, pulls, surface texture, friction, and air resistance affect the speed, direction, and shape of objects.

Explore non-contact forces including magnetism and gravity, test magnetic attraction and poles, and compare gravity and buoyancy.

Identify energy sources, explore heat transfer, understand electrical safety, and build simple battery circuits.

Explore light sources, shadow formation, reflection, sound vibrations, volume, and pitch.
