Name: Nahviah Owens Date: 1/24/24 Student Exploration: Weather Maps Steps: 1. Click “File”, then “Make a copy” in order to type on this document. 2. Log into Connexus (Pearson Online Classroom) to be able to access the simulation. 3. Click HERE to access the simulator - https://www.connexus.com/external/gizmos/default.aspx? idMedia=759935 Directions: Follow the instructions to go through the simulation. Respond to the questions and prompts in the orange boxes. Vocabulary: air mass, air pressure, cold front, high-pressure system, knot, low-pressure system, precipitation, warm front Prior Knowledge Questions (Do these BEFORE using the Gizmo.) 1. How would you describe your weather today? Warm and Windy 2. What information is important to include when you are describing the weather? The sun is out and it is not cloudy. Gizmo Warm-up Data on weather conditions is gathered from weather stations all over the world. This information is combined with satellite and radar images to create weather maps that show current conditions. With the Weather Maps Gizmo, you will use this information to interpret a variety of common weather patterns. A weather station symbol, shown at right, summarizes the weather conditions at a location. 1. The amount of cloud cover is shown by filling in the circle. A black circle indicates completely overcast conditions, while a white circle indicates a clear sky. What percentage of cloud cover is indicated on the symbol above? 25% Reproduction for educational use only. Public sharing or posting prohibited. © 2020 ExploreLearning™ All rights reserved
2. Look at the “tail” that is sticking out from the circle. The tail points to where the wind is coming from. If the tail points north, a north wind is moving from north to south. What direction is the wind coming from on the symbol above? south west 3. The “feathers” that stick out from the tail indicate the wind speed in knots . (1 knot = 1.151 miles per hour.) A short feather represents 5 knots (5.75 mph), a long feather represents 10 knots (11.51 mph), and a triangular feather stands for 50 knots (57.54 mph). Add the feathers to find the wind speed. What is the wind speed shown on the symbol above? 25 knots Activity A: High-pressure systems Get the Gizmo ready : ● Click New until you see a high-pressure system , represented by the symbol H . ● Turn on Show Mobile Station B data . ● Turn on Show land . Question: What weather patterns are associated with high-pressure systems? 1. Observe : Air pressure is equal to the weight of a column of air on a particular location. Air pressure is measured in millibars (mb). Note how the air pressure changes as you move Station B towards the center of the high-pressure system. A. What do you notice? That the pressure is going up . B. Why do you think this is called a high-pressure system? its pressure is higher than its surroundings . 2. Observe : Select Show satellite image to observe any clouds near the system. What do you notice about the cloud cover near the high-pressure system? its clear High-pressure systems are regions where air moves downward. Usually, few or no clouds form in these conditions.

Activity B: Low-pressure systems Get the Gizmo ready : ● Click New until you see a low-pressure system , represented by the symbol L . ● Check that Show Mobile Station B data and Show land are on. Question: What weather patterns are associated with low-pressure systems? 1. Observe : Note how the air pressure changes as you move Station B towards the center of the low- pressure system. A. What do you notice? wind speed increases B. Why do you think this is called a low-pressure system? it has less pressure 2. Observe : Select Show satellite image . What do you notice about the cloud cover near the low-pressure system? it stay clear until its station has arrived Low-pressure systems are regions where air moves upward. This can lead to condensation and cloud formation. Reproduction for educational use only. Public sharing or posting prohibited. © 2020 ExploreLearning™ All rights reserved
