  3. Friction Fred • Science Objectives: • Explain the meaning of friction. • Describe what happens with the absence of friction on a slick surface. • Use science process skills to compare friction among various surfaces.

  4. Friction Fred • Literacy Objectives: • Recognize the letter “Ff” and the sound of /f/. • Write the letter “Ff”. • Identify location of the /f/ sound in a word. • Recognize words in print beginning with the letter “Ff”.

  5. Friction Fred Kindergarten NS.1.K.1 NS.1.K.2 NS.1.K.3 PS.6.K.2 Demonstrate various ways that objects can move, including but not limited to: straight, zigzag, back and forth, round and round, fast and slow NOTE - Friction can be introduced during the study of this SLE by explaining that friction is needed for objects to go in a curved path on the ground, and causes objects to slow down if a force is not applied. PS.6.K.3 Demonstrate the effects of the force of gravity on objects. NOTE - Friction can be introduced during the study of this SLE by explaining that gravity is the downward force that is causing objects to press against the earth, etc.

  6. Friction Fred • Grade 1 • NS.1.1.1 • NS.1.1.2 • NS.1.1.3 • PS.6.K.2 List orally the various ways that objects can move, including but not limited to straight, zigzag, back and forth, round and round, fast and slow • NOTE - Friction can be introduced during the study of this SLE by explaining that friction is needed for objects to go in a curved path on the ground, and causes objects to slow down if a force is not applied.

  7. Friction Fred • Literacy Objectives for Higher Level Thinking: • Identify both regular and irregular words automatically through reading. • Create your own illustration for the Friction Fred story and write a paragraph to describe it. • Write a different ending to the Friction Fred story. • Write in a a science journal why it is betterto have rubber rather than leather soles on your shoes when walking on a slick surface.

  9. Friction Fred Rolling Friction – Note that only one small part of the surface is in contact, therefore much less friction.

  10. Friction Fred • Vocabulary Builders: • fascinated friction • fumble flannel • ferocious forfeit • fantastic favorite • frozen

  11. Friction Fred • Science Words to Know: • resistancemotion • statickinetic

  12. Friction Fred • Key science concepts: Discuss: • Friction – A force between two substances rubbing together. • Resistance: The force that opposes motion.

  13. Friction Fred • Distance Contest Activity: • Make an inclined plane (ramp) between the table and book with a ruler. • Crumple some aluminum foil, flatten back out and lay at end of “ramp”. • Release the marble from the top of ramp. • Measure distance from bottom of ramp to where the marble stops. • Do this several time to get accurate results. • Repeat process with sandpaper and wax paper. • Why surface allows the marble to roll farthest? Why?

  14. Friction Fred • Distance Contest Activity: • Conduct same as before, but allow the students to place their data in a table.

  15. Friction Fred • Magic Spoon Activity: • Wipe off any oil on your nose with paper towel. • Breathe onto the spoon’s curved part. • Touch the curved part to your nose. • Slowly release. • What happened? Why?

  16. Friction Fred • Grabbing Rice Activity: • Use funnel to fill small soda bottle with rice. • Insert pencil and start poking up and down. • Rice will settle and pencil will “grab”.

  17. Friction Fred • Salt and Marble Activity: • Place marble in test tube. • Fill ¾ full with salt. • Place stopper/cork on top of tube. • Hold tube vertically and shake up and down. • What happens after 25-75 “shakes”? Why?

  18. Friction Fred • Science Words to Know:
