Week 4: April 27 - May 1

Learning Goal:

I can predict the future motion of an object based on measurements and observations.

Estimated Time for The Week:

60-75 minutes

Type of Lesson:

Physical Science: Predicting motion using patterns

Materials:

• A ball
• toy car
• an object that doesn’t roll or have wheels
• tall book
• ruler
• piece of paper
• pencil

1. Review vocabulary words
   • Force
   • Balanced Force
   • Unbalanced Force
   • Motion
   • Strength
   • Gravity
2. Prepare - Creating the Table
   • For us to investigate we will need to record the data. For this we will create a table with 4 columns and 7 rows.
   • Title the table: Distance Traveled
   • Label the top left rectangle: Ramp Height
   • Label the other columns: ball, car, and place the name of the object on the final column.
   • Label the rows: 0 inches, 1 inch, 2 inches, 3 inches, 4 inches, and 5 inches.
3. Practice:
   • Find an area in which you can lean your book against something that won’t move, and enough space for your objects to roll without being interrupted.
   • With your book laying flat on the ground, place the ball on the book. How far did it travel? 0 inches. Record this on your table.
   • Now lean your book against something that won’t move (chair, couch, book shelf, wall, etc.) Prop your book so that one end is on the floor, and the other end is 1 inch off the floor.
   • Place your ball on the book at the top. Measure how far it rolls past the end of the book. Record your data.
   • Repeat the same steps for 2 and 3 inches. Remember to record your data. Be sure to release the ball from exactly the same spot each time.
4. Predict:
   • Look at your data for your ball rolling down the ramp at 0 inches, 1 inch, 2 inches, and 3 inches. Can you predict how far the ball will roll when the ramp is at 4 inches? What about when the ramp is at 5 inches?
   • Write down your predictions and investigate. Were your predictions correct?
5. Practice:
   • Now, conduct the same investigation with the toy car, and your object. Record how far they travel at 0 inches, 1 inch, 2 inches, and 3 inches. Then make predictions of how far they travel when the ramp is at 4 inches and 5 inches. Investigate your predictions. Were they correct? Be sure to release the car and object from exactly the same spot you released the ball from.
6. Alternate Investigations: Different Surfaces
   • How do surfaces compare? Compare a rough surface to a smooth surface. Compare a soft surface to a hard surface.
   • Which surface allowed the ball, car, and object to roll furthest.
7. Challenge:
   • Looking for something more challenging?

Learning Goal:

I can create bubbles of different sizes using a homemade bubble solution and a variety of household items.

Estimated Time for The Week:

20-30 minutes

Materials:

• flat bowl or dish
• water
• sugar
• dish soap
• measuring cup
• measuring spoon
• variety of household items to use as a wand (wire hanger, straw, kitchen funnel, disposable plastic cup, string - use your imagination)

Learn & Practice:

1. Create your bubble solution by mixing the following ingredients in a flat bowl or dish:
   • 1 ½ cups of water
   • ½ cup of dish soap
   • 2 teaspoons of sugar
2. Choose three household items that you would like to use as your bubble wand. (If you use a disposable plastic cup, have an adult help you make a small hole in the bottom of it.)
3. Dip the edge of your homemade wand into the bubble solution and gently blow a bubble or wave your wand gently through the air. You may need to dip the wand multiple times into the solution in order to blow a bubble.
4. Repeat with the other two wands.
5. Compare the three bubbles you made.
   • Were your bubbles the same size? If not, why?
   • How does your wand determine the kind of bubble you blew?
   • Which technique worked better with your homemade wands - blowing gently into it or waving it gently through the air?
   • How did the technique change the bubble?

FUN FACT: The largest outdoor free floating soap bubble had a volume of 3,399.7 feet and was made by using string tied between two fishing poles! Gary Pearlman of Ohio set this Guinness World Record in 2015.

Optional Extension Activity: Using a different recipe could change the size or appearance of your bubbles. Create a different bubble solution, using a different recipe like these:

• Bouncing Bubbles
• Giant Bubbles
• Life-Sized Bubbles
