Grade 2 Science

Can you fool someone to think hot is cold and cold is hot ? How does a thermometer work and could I build my own? Does snow take up more or less space when it melts? Does heating or cooling a potato change it - how? Build your own solar heater! Study how a thermos works and build your own!

Lesson 1: You are junior physicists studying temperature. You will discover many neat things about temperature and how it effects our lives.

What is Hot and Cold? double bubble map- hot and cold //**I can recognize the effects of heating and cooling and identify methods for heating and cooling.**//

Lesson 2:

Lesson 3: I can describe temperatures using "hotter than" and "colder than".

What is temperature? -book - That's Hot" by Auch

-use a thermometer -experiment with thermometers and hot and cold water-(measure in degrees Celsius) bridge map- hot is to cold as.... -experiment- thermometers and doors open/hallways

Lesson 4: I can describe ways in which temperature changes and affects our daily lives. -connect with Metaghan and Australia. Make a video (using cameras) of the weather in Rocky and things that we can do in this weather. http://www.bbc.co.uk/schools/scienceclips/ages/8_9/keeping_warm.shtml

Lesson 5: I can recognize that the human body temperature is relatively constant and that a change in body temperature is a sign that there is a change in health.

-Guest Speaker- Nurse

Lesson 6:

I can identify safe practices for handling hot and cold materials and for avoiding potential dangers from heat sources. Describe how heating an cooling materials can often change them (melting, freezing, cooking, burning). experiment- heating and cooling- making kool aid ice cubes experiment- balloon bottle

Lesson 7:

I can describe how buildings are heated: -identify the energy source -Recognize that most buildings are heated by circulating hot or cold air -describe how heat is circulated through the school building and their home (discuss the thermostat)

Lesson 8: I can identify materials that insulate animals from the cold (wool, fur, feathers) and identify materials that are used by humans for the same purpose. -Forest Ranger http://www.simplyinsulate.com/content/resources/science.html

Lesson 9: I can describe the role of insulation in keeping things hot or cold and identify places where some form of insulation is used (clothing, reigerator, coolers, homes). Guest Speaker- Jeremy I can design and construct a device to keep something hot or cold. -thermos
