Interactive topics:

• Hail size estimation - this is a simple exercise involving Styrofoam balls. The object for the student is to estimate the size of hail by comparing the balls to standard round objects such as golf balls, tennis balls, grapefruit, etc.
• Bernoulli experiment - this experiment involves several ping-pong balls suspended by string. Students will be asked to act as "wind" by blowing on the suspended ping-pong balls from various angles. By blowing between adjacent ping-pong balls, the students will observe the "Bernoulli effect"; that is, the balls will be attracted to each other because of the low pressure created because of the velocity of the students' breath
• Rain gauge object lesson - this lesson shows students how rain gauges work to estimate ow much rain has fallen. Some students will blind-fold themselves and act as the "rain" (they will hold foam "rain drops"). Other students will act as the "rain gauges" (holding a bag to deposit the foam balls). The blindfolded students are then directed to put the "rain" in the "rain gauge." This process demonstrates how error can sometimes occur in rain measurements

Talks:

• Show and Tell: Weather - students will be taught basic lessons about the atmosphere. Included will be images of weather phenomena including snow, lightning and tornadoes.
• Severe Weather Safety - students will be asked to identify what they think would be good things to have with them when taking shelter from a tornado. After this, students will be shown an example safety kit including First-Aid supplies, blankets, flashlights, etc. Thereafter, students will be taught how to take tornado safety precuations during a tornado.
