Kesler Science Station Lab – Conduction, Convection, & Radiation – Teacher Directions

Explore It! – I will spend much of my time at this station making sure students are understanding the concepts. You will need a lamp, 2 beakers, 2 metal rods/spoons, hot plate, ice. One of the beakers needs ice water and the other needs just above lukewarm water. CAREFUL!

Illustrate It! – Make sure to include colored pencils or crayons at this station.

Read It! – Print several different copies (I use 6) of the reading passage so that multiple students can read at different paces

Watch It! – The video is on YouTube and my Google drive. Use YouTube unless your school is blocked. The original link is http://studyjams.scholastic.com/studyjams/jams/science/energy-light-sound/heat.htmNote that both URL’s are case-sensitive.

Organize It! – All of the cards are included for this station. The cards for this activity are attached near the activity. Students should be encouraged to do the Research and Explore station before attempting this one. I like to label the backs with set numbers because they will get mixed up. Place this one next to the Explore It! Station.

Write It! – Students should be encouraged to do the Research and Explore station before attempting this one.

Research It! – The goo.gl link on the task card is case-sensitive. The original link ishttp://www.pbslearningmedia.org/asset/lsps07_int_heattransfer/

Assess It! – Students should be encouraged to do the Research and Explore station before attempting this one. If I grade anything I usually take a close look at the answers from this station.

It is recommended that you have completed at least two of the following stations before working at this station.-Read It!-Explore It!-Watch It!-Research It!

Answer each of the task card questions on the lab sheet in complete sentences.

What is heat?

After watching the examples in the video of radiation, list 2 other examples that you come up with on your own.

1. Click Play on the video.2. Answer questions from cards

#2-4 on your lab sheet.

Explain what convection is and provide an example.

Each member of the group will go to the website listed on task card #1

When two objects are in direct contact with each other (touching) heat is able to transfer. This is called conduction. 1. Come up with two other examples

of conduction on your lab sheet.©KeslerScience.com ©KeslerScience.com

©KeslerScience.com

1. Touch the metal in the cold water and then touch the metal in the warm water. Make some observations on your lab sheet.

Heat always transfers from hotter objects to cooler objects.

1. Use the large diagram at the station to make some observations about how heat is transferring in each of these situations. Are there any similarities? What are they?

Earth’s mantle, Earth’s oceans, and Earth’s atmosphere contain convection currents.1. Come up with two other

specific examples of convection on your lab sheet.

When heat flows through a liquid or a gas it is called convection.

The objects are not touching each other in the example of radiation.

1. Come up with two other examples of radiation on your lab sheet.

1. Look at the lamp at the station and make some observations about how heat flows from the lamp. You may place your hands close to the lamp, but do not touch it.

When heat is transferred through electromagnetic or radio waves it’s called radiation.

Each member of the group will draw a quick sketch on the lab sheet that shows they understand the concept being taught.

Use the colored pencils and markers that are provided.

The directions for the sketch are provided on the task card at the table.

Illustrate It! Station Directions

Use the colored pencils to draw a 3 different pictures that illustrate the concept of convection, conduction, and radiation.

Be sure to include labels for each of your images and a brief summary of what each term means.
