2E+Sci+hot+and+cold

__﻿Lesson 1: Introduction __
 * Read a book about hot and cold temperatures
 * Read the poems Deep Freeze and Melt Down
 * Put piece of white paper in front of binder – write title Hot and Cold Temperatures
 * Look at some pictures and decide if they are showing things that are __//cold or hot.//__
 * Fold a piece of white paper into 4. On one side students draw and lable 4 hot things and on the other side 4 cold things. Then in groups they list and draw ideas on chart paper.

__﻿Lesson 2:__ ** Describe temperature in relative terms, using expressions, such as hotter than, colder than. (SLE 1) **  ** 1. **  **PowerPoint** slide 1 - 3 
 * Discuss what temperature is and relative hotter or colder

**2. Temperature Time Line – **Helps students understand relative temperature and to use the terms hotter than, colder than 
 * Review the temperature at which water freezes and boils by looking at the interactive //__changes of states__// on the smartboard.
 * <span style="color: #000000; font-family: 'Arial','sans-serif'; font-size: 11pt;">Put the //__temperature timeline__// on the smartboard. Place the Water freezes card at 0 and talk about what it means if a temperature if above or below 0.
 * <span style="color: #000000; font-family: 'Arial','sans-serif'; font-size: 11pt;">Choose a statement from the side and ask a students to tell whether it will be hotter or colder than one already on the board. How much hotter or colder? Decide as a class where to put the statements.
 * <span style="color: #000000; font-family: 'Arial','sans-serif'; font-size: 11pt;">Have students get into groups and try to recreate the temperature line in the same manner. Once they have it all lined up check with teacher.

<span style="color: #000000; font-family: 'Arial','sans-serif'; font-size: 11pt;">**3. PowerPoint** slides 4-5 <span style="color: #000000; font-family: 'Arial','sans-serif'; font-size: 11pt;">
 * <span style="color: #000000; font-family: 'Arial','sans-serif'; font-size: 11pt;">Go through slides on the powerpoint
 * <span style="color: #000000; font-family: 'Arial','sans-serif'; font-size: 11pt;">On their own students recreate the temperature timeline and glue down the statements where they think they belong.

<span style="color: #000000; font-family: 'Arial','sans-serif'; font-size: 11pt;">**4. Reading Comprehension** - students complete reading comprehension __//About a Thermometer//__

__ ﻿Lesson 3: __ **<span style="font-family: 'Arial','sans-serif'; font-size: 11pt;">Measure temperature in degrees Celsius (°C) (SLE 2) ** <span style="font-family: 'Arial','sans-serif'; font-size: 11pt;">
 * <span style="font-family: 'Arial','sans-serif'; font-size: 11pt;">1. Learning to Measure Temperature ** **-** <span style="font-family: 'Arial','sans-serif'; font-size: 11pt;">Look at a large thermometer and talk about the parts and how the liquid moves. Discuss what the liquid is and why.
 * <span style="font-family: 'Arial','sans-serif'; font-size: 11pt;">Each student gets a copy of //__Measuring Temperature__// <span style="font-family: 'Arial','sans-serif'; font-size: 11pt;">and a thermometer.
 * <span style="font-family: 'Arial','sans-serif'; font-size: 11pt;">Talk about the parts of the thermometer and complete the page together.
 * <span style="font-family: 'Arial','sans-serif'; font-size: 11pt;">Have students make predictions about what will happen when the thermometer is placed in hot or cold water and then test it out and record reults.

<span style="font-family: 'Arial','sans-serif'; font-size: 11pt;">**2. Practice, Practice, Practice** - Students practice reading temperatures on the __//interactive thermometers//__ on the smartboard. <span style="font-family: 'Arial','sans-serif'; font-size: 11pt;"> <span style="font-family: 'Arial','sans-serif'; font-size: 11pt; line-height: 0px; overflow: hidden;">
 * <span style="font-family: 'Arial','sans-serif'; font-size: 11pt;">Be sure to talk about how to read the thermometer when the temperature is below zero.
 * <span style="font-family: 'Arial','sans-serif'; font-size: 11pt;">Talk about what the approximate temperature would be in different situations and what the thermometer would look like (ex. if you were skating, if you were swimming at the beach, in our classroom etc.)
 * <span style="font-family: 'Arial','sans-serif'; font-size: 11pt;">Show two theremometers and talk about which might show a certain situation (warmest thermometer, the one that shows a cold winter day etc.)


 * <span style="font-family: 'Arial','sans-serif'; font-size: 11pt;">3. Temperature around the school - **<span style="font-family: 'Arial','sans-serif'; font-size: 11pt;">Prior to activity 6 thermometers are placed in different spots around the school.
 * <span style="font-family: 'Arial','sans-serif'; font-size: 11pt;">Students fill out information on the //__Measuring temperature around the school__// sheet before recording any temps.
 * <span style="font-family: 'Arial','sans-serif'; font-size: 11pt;">As a group go to the different areas of the school and have volunteers read the thermometers. Students record temp. on their sheet.
 * <span style="font-family: 'Arial','sans-serif'; font-size: 11pt;">Return to class and students graph results.
 * <span style="font-family: 'Arial','sans-serif'; font-size: 11pt;">Discuss reasons for the differences in temp.

<span style="font-family: 'Arial','sans-serif'; font-size: 11pt;">**4. Show What You Know -** <span style="font-family: 'Arial','sans-serif'; font-size: 11pt;">Students complete a booklet called __//Labeling Thermometers//__ to show what they know about reading thermometers.

__ Lesson 5: __<span style="font-family: 'Arial','sans-serif'; font-size: 11pt;">**<span style="font-family: 'Arial','sans-serif'; font-size: 11pt;">Describe how heating and cooling materials can often change them; e.g., melting and freezing, cooking, burning (SLE 3) ** <span style="font-family: 'Arial','sans-serif'; font-size: 11pt;">**<span style="font-family: 'Arial','sans-serif'; font-size: 11pt;">1. Heat Changes Things **
 * <span style="font-family: 'Arial','sans-serif'; font-size: 11pt;">talk about how heating or cooling things might change them (pancakes, jello melting, freezinf etc)
 * <span style="font-family: 'Arial','sans-serif'; font-size: 11pt;">Review the water cycle and talk about how heating and cooling liquid creates the water cycle
 * <span style="font-family: 'Arial','sans-serif'; font-size: 11pt;">As a class read through and complete //__Heat Changes Things__//


 * <span style="font-family: 'Arial','sans-serif'; font-size: 11pt;">2. Baked Potato! **
 * <span style="font-family: 'Arial','sans-serif'; font-size: 11pt;">each student gets a potato and a copy of the lab
 * <span style="font-family: 'Arial','sans-serif'; font-size: 11pt;">Talk about properties of the potato before cooking and predict changes after cooking
 * <span style="font-family: 'Arial','sans-serif'; font-size: 11pt;">Bake potatos in oven and fill in lab sheet, then enjoy eating the potato


 * <span style="font-family: 'Arial','sans-serif'; font-size: 11pt;">3. Chocolate Ice Cream! **
