Investigating Density
Mass, Volume and Density
Measure the mass and volume of different materials to calculate their density. Test predictions by placing objects in water.
"The atoms or elementary particles themselves are not real; they form a world of potentialities or possibilities rather than one of things or facts."
Investigating Pressure
Force and Area
Explore how pressure depends on force and area. Adjust the force and contact area to see how pressure changes.
Pressure in a Liquid
Depth and Liquid Density
Investigate how pressure in a liquid increases with depth and varies with liquid density using the equation P = ρgh.
Investigating Pressure and Volume
Boyle's Law
Compress a gas using a piston and measure how pressure changes with volume at constant temperature. Verify Boyle's Law: PV = constant.
Investigating Pressure and Temperature
Gay-Lussac's Law
Heat a sealed gas container and observe how pressure changes with temperature at constant volume. Explore the pressure-temperature relationship.
Change of State Investigation
Heating and Cooling Curves
Heat a substance and track temperature over time. Observe the characteristic flat regions during melting and boiling where latent heat is absorbed.
Specific Heat Capacity
Energy and Temperature Change
Heat different materials with a known power supply and measure the temperature rise to calculate and compare specific heat capacities.
