Pressure Effects

Physical science learners conduct a simple experiment using the heat of their hands to affect the fluid pressure. They place a balloon atop a freezing cold bottle and observe what occurs as it warms up. Both activities demonstrate how...

Students discuss ways they might visually see pressure differences, and work in groups to create experiments to predict and prove what a change in pressure can do to objects exposed to the change.

Sometimes, despite the best laid plans, the unexpected will occur. Learners witness this firsthand as they carefully design an experiment to determine the time needed for ice to melt in salt water or pure water. They uncover facts not...

Engage the class like never before as pupils learn to differentiate between multiple physical and chemical changes by conducting a list of small experiments, most often with household materials. They make observations and discuss the...

Ice is nice, and its condition on the planet has a significant effect. Junior geoscientists experiment with ice melting in both water and on land to discover how each affect the rising sea level. This detailed lesson outline even...

Begin by discussing pressure and showing a video clip of James Cameron's record-setting deep-sea dive. Then assign lab groups to explore how depth affects pressure and to construct a manometer. There is another video to follow the...

What better way is there to introduce conservation of mass than a few simple experiments? Young chemists conduct two chemical reactions, take the masses of reactants and products, then compare their results to determine differences in...

Investigate what is pushing on us. An intriguing lesson has pupils calculate the amount of force on various squares due to air pressure. Using the data, individuals create a graph in the third lesson of the Up, Up and Away unit...

Learners explore the concept of air pressure. Using candy or cookie wafers to model how air pressure changes with altitude, they conduct an aluminum can crushing experiment, compare the magnitude to gravitational force per unit area,...

Change is coming — but how much? Geology pupils discover the transformation of metamorphic rock using a well-rounded interactive. Topics include the effects of pressure and temperature on metamorphic rock, how time factors into the...
