Using ultrasound to meas- ure distance, the motion detector emits pulses, which are reflected from a target, and then detected by the device. The time it takes for the reflected pulses to return is then used to calculate position, velocity, and acceleration. The detector can measure objects within a range of 15 cm to 6 m. The short minimum target distance allows objects to be closer to the detector and reduces stray reflections.

Everything you need to complete the demonstration is provided and the entire experiment is performed in a heavy-duty plastic, zipper-lock bag so your students can feel and study the reaction closely, but safely. After observing the demonstration, students are motivated to continue explorations of the concepts observed. Explain the science and then let students expand and further their understanding by asking questions and proposing predic- tions and hypothesis. Their questions and hypothesis determine the direction of the lesson — ask students how you might test the parameters they suggest. Increase the students’ understanding by repeating the demonstration using their recommendations. Each kit contains enough material to repeat the demonstration about 20 times.

Extension activities also area. This barometer operates without liquid, but uses a allow you to use the device to explore Earth’s heat transfer thin metal diaphragm mechanism to measure the effect of cycles; including radiation, conduction, and convection currents atmospheric pressure. The unit is circular, constructed of two identical convoluted and their impact on both air and ocean circulation, and the diaphragms sealed at their edges. When this capsule is completely evacuated of movement of magma deep beneath the Earth’s crust. The air, it will respond to pressure changes in the atmosphere. Such changes propor- demonstrator includes one Plexiglas wheel, two super magnets, tionally affect the changes in the thickness of the capsule, which are magnified clear tubing, bumper pads, steel balls, and a variety of clips and through levers, finally causing a needle to rotate over a circular scale divided into connectors, along with a detailed teacher’s guide, and set of equivalent inches of mercury and millibars. This action observed on the Barometer activity transparencies. Tutor gives students full understanding of barometric pressure. Size: 8" diameter. WL1805-97 WL1805-98
