A toy that demonstrates a physical change is a stretch toy that can be elongated and then returns to its original shape, such as a slinky. When you stretch the toy, the molecules inside rearrange temporarily, but once released, they revert back to their original arrangement, showing a physical change.
Yes, it is.
This demonstrates a physical change. The way the clay looks is now physically different because the shape of it has changed.
A melting candle is an example of a physical change, not a chemical reaction. The process involves a solid candle turning into liquid wax due to the application of heat, with no change in the chemical composition of the wax molecules.
physical, because it can be easily reversed
A toy is a physical model.
A toy is a physical thing.
Legos
Yes, it is. You aren't altering the chemical composition at all - it's still copper - you are merely changing its shape.
Physical-it is still wood, just in small pieces
A lava lamp demonstrates a physical change. The wax inside the lamp changes states from solid to liquid due to the heat of the light bulb, but its chemical composition remains the same throughout the process.
Observing trends in physical characteristics and grouping them in a way that demonstrates gradual change.
