任務Task
設計和進行一個公平測試，以找出紙杯還是發泡膠杯的保温能力較強
Design and carry out a fair test to find out whether a paper cup or a foam cup can do better in keeping temperature
簡介
Introduction
Pasco生產的無線温度感應器是以不銹鋼製成的温度探測器，適合在不同的實驗中使用，以量度温度的變化。
Pasco wireless temperature sensor is a wireless sensor with a stainless steel temperature probe. It can be used in different experiments to measure temperature changes.
Students can get instant temperature readings and monitor the temperature change continuously, by using an app called ‘SPARKvue’ on any mobile devices or tablets.

第一部分—使用無線温度感應器Part A—How to use the wireless temperature sensor
閱讀說明書，或在互聯網搜尋Pasco無線温度感應器的使用方法。
You can search the Internet or read the user guide of Pasco wireless temperature sensor to learn how to use the temperature sensor.
你需要下載流動應用程式「Sparkvue」，並把無線温度感應器連接至程式。然後，研究如何使用程式來記錄温度變化。
You also need to download the app ‘Sparkvue’ and connect the temperature sensor to this app. Then study how to use this app to record the temperature readings.
