Name: Katlyn Travis Title: Weather Grade Level: First Grade Benchmarks: E.ES.01.31 Identify tools used to measure temperature, precipitation, cloud cover, and wind. E.ES.01.32 Observe and collect data of weather conditions over a period of time. Objectives: (Science Net Links, 2011) The student will be able to: Describe ways to measure the temperature, cloud cover, wind speed and direction, and precipitation. Record data from observations and measurements. Report observations and data collected. Demonstrate proper use of tools such as a thermometer, rain gauge, anemometer, and visual observations to collect data. Materials and Setup: Different accessories (sunglasses, snow pants, rain boots, umbrella, etc.) Youtube video: http://www.youtube.com/watch?v=9rBVyASNLxM Thermometer (for every two students) Rain gauge (for every two students) Anemometer and wind vane (for every two students) Lab sheet (one for each student) Weather worksheet (one for each student) Requisite Knowledge/skills for students: Students do not have to have any requisite knowledge for this lesson. Procedure: Engage: Introduction to the concept of weather will be done by the teacher coming into the classroom wearing all different kinds of clothing (sunglasses, umbrella, rain boots, snow pants, winter coat, etc.). First grade students will notice and ask the teacher why they are dressed like that. The teacher will ask the students to point out which items of clothing doesn’t belong and why. (e.g. If it is sunny out the students will say the umbrella and rain boots. Or if it is summer time the snow pants and gloves do not belong). The teacher will ask the students how they know what clothes she should be wearing (students may say sunglasses because it is sunny, etc.) 1 Explore: The teacher will then divide the board into 4 categories: temperature, wind, precipitation and cloud cover. Each category will be discussed and examples of each will be placed on the board. Some examples may be to put rain and snow in precipitation, cloudy or clear in cloud cover, hot or cold in temperature, etc. The teacher will then ask the students if they know of any ways in which to measure the four different weather conditions. Students will say things like looking outside, reading a thermometer, etc. The teacher will make a list of the suggestions (Objective 1). Students will then watch a youtube video (http://www.youtube.com/watch?v=9rBVyASNLxM) of several instruments that are used to measure weather and write down the main words (thermometer, rain gauge, etc.) under the condition they help measure. Explain: The teacher will show students the instruments (thermometer, anemometer, rain gauge) and have the students’ partner up. Each person will get their own lab sheet and each pair will get their own instruments. The students will fill out the worksheet recording observations (is it cloudy/is it raining/does it feel hot or cold?) as well as data (temperature in degrees/wind direction). The class will be going outside everyday for one week and will need to collect the data for each day. They can set up their rain gage on the first day and record the collected amount for each day. (Objective 2 and 4) Students will use their data they collected to complete the worksheet provided to turn in for a grade. (Objective 2). An exit card will be filled out by each student to turn in at the end of the discussion that describes one way to measure the temperature (by feel or thermometer), wind speed/direction (by feel or anemometer), cloud cover (observation), and precipitation (observations or rain gauge). (Objective 1) Elaborate: Each day one students will act as “news anchor” and report the current weather to the class. They are to use the data they collected but are also free to reference the weather channel if they watched it that morning. The students will be graded on using the correct terms (e.g. the temperature today will be 63 degrees, it is partly cloudy, etc.) (Objective 3) Evaluate: Exit Card Objective 1 Lab Sheet/Working outside to collect data Objective 2 and 4 Students will give an example of one way to measure each of the 4 discussed weather conditions Students will record their observations and measurements on a lab sheet Summative: will be graded based on correct use of tools for each weather condition Formative: will not be graded but instead used for students to fill out the sheet that 2 Class Discussions Objective 1 Final Work Sheet Objective 2 News Anchor Objective 3 goes along with it. Students will Formative: students participate in class will be required to add discussions throughout at least one comment the lesson during this lesson. Teacher will keep track by giving 5 points to those that comment. Students will use their Summative: will be data and observations graded based on to complete a completeness and how worksheet that well it correlates to summarized the their data. information collected Students will act as Summative: will not the news anchor (one be graded but teacher student/day) and will look for correct report the weather usage of vocabulary using either their data words. or by observing the morning news Scientific Background for the Teacher The weather can be measured by kinds of tools. For first grade they will stick to the basic of weather and only measure things like temperature, wind speed and direction, cloud cover, and precipitation. The temperature can be defined as the measure of the average kinetic energy of the atoms that compose a substance (Moran, 2001). Several different tools can measure the temperature of the air but for a basic introduction it is easiest to use the thermometer. A thermometer is usually filled with mercury that expands when the glass part of the thermometer comes in contact with the substance being measured. The way to read a thermometer is to use the scale and record the number (using degrees Fahrenheit) at the top of the mercury level. The wind speed and direction can be measured using an anemometer. There are once again several different types of anemometer but we will be using a basic one. The anemometer to be used in this lesson consists of three cups on a horizontally spinning shaft. The students will measure the speed based on how fast the cups are spinning. A wind vane will also be used to record which direction the wind is blowing. A wind vane consists of an arrow and a North, South, East, West compass. The arrow will point to the direction to which the wind is blowing. Cloud cover can be actually measured but for basics students will just observe the sky. Depending on the amount of clouds they will write down either sunny (no clouds), mostly sunny (few clouds), partly cloudy (more clouds than sun), or cloudy (sky is completely covered with clouds). 3 Precipitation includes rain, snow, sleet, and hail. This can be recorded simply based on observation (is it raining out?) but can also be measured using a rain gauge. A rain gauge is an instrument that is made of a cylinder with a funnel on top. The funnel catches the precipitation, which then collects in the cylinder. The cylinder will have measurements on the side (measured in inches) that can be read and recorded depending on how full of water it is. References Cited F1zban88. "Measuring Weather." YouTube.
