Shaw Survey Shaw STEM Lab - 2017

Overview § Our environment is important to all of us. § In this activity you will investigate our school as an environment. § Scientists study large areas by looking at samples. § In this experiment, you will gather data from around the school.

Objectives § In this experiment, you will § Measure ground air temperatures at various locations around our school § Determine if there are temperature differences between the ground air above it § Organize your results

Materials § Lab. Quest 2 § Temperature Probe § Light Sensor § Ruler

Lab. Quest 2 § Note: The Lab. Quest 2 is a very expensive piece of equipment § You are responsible for it, pleas make sure to take care of it § Be sure to use the stylus to touch or select things on the screen

Selecting Where to Collect Data § Select at least four different areas to collect data from § All four places need to be either indoor or outdoor – not both § Make sure your locations are approved before continuing

How to and What Data to Collect Description of Location Temperature (at surface in °C) Temperature (at 5 cm in °C) Temperature difference (°C) Light Intensity (at 5 cm)

How to and What Data to Collect § Connect the Temperature Probe and Light Sensor § Ensure the Light Sensor is set to the 0 -150, 000 lux position

How to and What Data to Collect: Part 1 § In your first location § Place the tip of the Temperature Probe on the ground § Note: if there is direct sunlight on the tip during data collection, the readings will be too high. To prevent this, use your hand to shade the tip of the probe. § Have one person cover the tip of the Light Sensor with their hand so that the ground level light intensity values will be zero. § Wait approximately one minute for the temperature reading to stabilize, then press the START/STOP button on the Lab. Quest 2. This will collect one set of temperature and light data.

How to and What Data to Collect: Part 1 § Repeat the previous slide and steps in your other locations

How to and What Data to Collect: Part 2 § Return to your first location. § Fasten the Light Sensor to a ruler using two rubber bands. § Slide the Temperature Probe under the rubber bands on the other side of the ruler as shown in the image. § Both probe tips should be at the 5 cm mark on the ruler.

How to and What Data to Collect: Part 2 § Measure the temperature and light intensity 5 cm above the surface by repeating the previous slide at your other locations. § Note: If it is a sunny day, hold the ruler so that the Temperature Probe is on the shady side.

Questions § Which location had the greatest difference between the two temperatures? § Which location had the smallest difference between the two temperatures? § Explain why you think this could be.

Hot to and What Data to Collect: Part 3 § If there is time, ask for different types of sensors § Repeat the experiment except in the opposite location § If you did it inside, do it outside § If you did it outside, do it inside
