PARTICLE MODEL OF MATTER EXPLORED
Science for years 5 and 6 has begun with a study in the properties of solids, liquids and gases. Using the particle model, we have formed hypotheses as to what differences we’d expect from solid CO2 and gas CO2.
An example of sublimation (a solid missing the liquid phase and turning straight to a gas), we have enjoyed uncovering some of the mysteries of gases, as CO2 (g) behaves in some very interesting ways!
Continuing our studies in gases, we next posed the question “Do gases take up space?”. The answer can be seen in the photograph below.
Next time…Using our sense of taste to discover the effects of CO2 (g) on water!
