Spring into Science

Suzanne Roberts

Description

Students become investigative scientists through observing, recording, and analyzing data collected from Wakulla Springs Video Web Camera.

Objectives

The student understands that although the same scientific investigation may give slightly different results when it is carried out by different persons or at different times or places, the general evidence collected from the investigation should be replicable by others.

Materials

- White drawing paper
- Colored pencils
- Venn Diagram template (teacher-created)
- Internet access to the Web World Wonders--Wakulla web camera (see URL in Weblinks section)
- LCD panel or something comparable
-Naturalist Log (see URL in Weblinks to obtain copy)

Preparations

1. Locate painting or landscape
2. Download and copy Naturalist Log from Web World Wonders site (1 copy per student)
3. Copy of Venn Diagram Template (1 copy per student)
4. Connect LCD panel or comparable device

Procedures

1. Present students with a landscape photograph or painting. Ask students to view the picture for 5 minutes and list or illustrate as many features as possible while viewing.

2. Create a list on the overhead projector based on student responses, and focus on the variation of the attributes students generated. This helps to illustrate the point of different results obtained by different persons while collecting data.

3. View the Wakulla Springs Website for 10 minutes with students. Instruct the class to complete the Naturalist Log individually, without communication with other students.

4. Place students in groups of two to complete a Venn Diagram to compare and contrast their observations. One student records his/her observations in one circle, while the other does the same in the other circle. They then record the findings they have in common in the overlapping area. Finally, have them make two statements comparing the data collected in their diagram.
(Possible response: Both Jamie and Rhonda observed moss-covered trees. However, Jamie was the only one to observe a snake on the tree limb.

5. Facilitate a class discussion of similarities and differences recorded by each group. This should make the point that most students observed similar items, although some differences occurred. Have the students add a statement on their papers summarizing the results of their findings regarding replication of scientific investigations.

Assessments

Students complete the Naturalist Log and a Venn Diagram to compare varying observations as a formative assessment.

Each student will have a minimum of 10 items that are represented on the Venn diagram, and all items will be placed accurately on the diagram (observations that were made individually and observations that they have in common).

Students should:
-accurately place at least 8 of the 10 items,
-make two accurate statements comparing the data, and
-correctly conclude that general evidence collected from an investigation is replicable.
