RATIONALE FOR ADVENTURE

Taking part in this Webelos/Arrow of Light elective adventure will help Webelos understand and apply the role of fair investigations in science. They will acquire and evaluate information using processes associated with science, such as experiments, observation, and note taking.

TAKEAWAYS FOR CUB SCOUTS

  • Increased content knowledge in one or more areas
  • Methodical problem solving
  • Evaluating evidence
  • A Scout is cheerful. [Webelos Character Compass]

ADVENTURE REQUIREMENTS (Webelos Handbook, page 206)

Do all of these:

  1. An experiment is a “fair test” to compare possible explanations. Draw a picture of a fair test that shows what you need to do to test a fertilizer’s effects on plant growth.
  2. Visit a museum, a college, a laboratory, an observatory, a zoo, an aquarium, or other facility that employs scientists. Prepare three questions ahead of time, and talk to a scientist about his or her work.
  3. Complete any four of the following:
    a. Carry out the experiment you designed for requirement 1, above. Report what you learned about the effect of fertilizer on the plants that you grew.
    b. Carry out the experiment you designed for requirement 1, but change the independent variable. Report what you learned about the effect of changing the variable on the plants that you grew.
    c. Build a model solar system. Chart the distances between the planets so that the model is to scale. Use what you learn from this requirement to explain the value of making a model in science.
    d. With adult supervision, build and launch a model rocket. Use the rocket to design a fair test to answer a question about force or motion.
    e. Create two circuits of three light bulbs and a battery. Construct one as a series circuit and the other as a parallel circuit.
    f. Study the night sky. Sketch the appearance of the North Star (Polaris) and the Big Dipper (part of the Ursa Major constellation) over at least six hours. Describe what you observed, and explain the meaning of your observations.
    g. With adult assistance, explore safe chemical reactions with household materials. Using two substances, observe what happens when the amounts of the reactants are increased.
    h. Explore properties of motion on a playground. How does the weight of a person affect how fast they slide down a slide or how fast a swing moves? Design a fair test to answer one of those questions.
    i. Read a biography of a scientist. Tell your den leader or the other members of your den what the scientist is famous for and why his or her work is important.

NOTES TO DEN LEADER

Note that these plans outline more meetings than necessary to complete the requirements. Only four activities must be completed for requirement 3, but the meeting plans offer ideas for all nine options, depending on what the Scouts select. Den leaders should plan accordingly and decide which meetings best lead to completing the adventure.

The Meeting 1 plan outlines a den outing to an institution that employs a scientist, and an optional Meeting 5 could be an outing to observe the night sky. In advance of each outing, the leader will need to make arrangements with the outing location and confirm the outing plan with families, including transportation and any additional items they need to bring. Make sure a tour and activity plan has been submitted, if required, and activity consent forms are distributed, signed, and collected.

If some Scouts decide to read the biography of a scientist, it would be helpful to establish this early in the adventure. This would allow them time to share with others in the den what they learned about the scientist.

Brainstorming how to carry out an activity one week before it is scheduled will help you to use den time well and to have any needed materials on hand. See the meeting resource sections for guidelines and suggested materials lists to carry out the investigations.

See the Appendix for optional den meeting activities, including openings, gatherings, and closings.

MeetingPlans

To get you started in delivering fun and engaging meetings, complete Den Meeting Plans are available here on the Learning Library for the Backyard Jungle and Games Tigers Play adventures. To obtain Den Meeting Plans for all other adventures, Den Leader Guides are available at your local Scout Shop, online at scoutstuff.org, or as an eBook through Amazon.
