State Goal Content

Design scientific investigations to answer biological questions. Create testable hypotheses, Identify variables (Responding, Manipulated, Dependent, Independent), Use a control or comparison group when appropriate, Experimental Goup, Select and use appropriate Measurement tools. Intro Scientific Method.

Activities

1. Anticipatory Set: Students will be given a sample of mystery powder (sodium poly acrylate) and water.
Students will: Students will mix powder and water. Students will the brainstorm uses of the new magical mystery powder.
COMPREHENSION:
The class will be divided into collaborative groups each group will be asked to choose the best possible usage for the mystery powder.

2. Anticipatory Set: Students will view several diaper commercials and note claims.
Students will create a (class / team product): Each group will be given a diaper brand and asked to measure and record total amount of water absorbed.
Multicultural and/or ESL and/or Bilingual Link:
Mathematics/Science Link and/or Humanities Link: Students will compare group results and create a bar graph of company brands.
School-to-Career/Tech Prep Link: Invite chemist to discuss the design and marketing of chemical compounds.

3. Anticipatory Set: Medicine Man (1992) Sean Connery clip showing trials
Students will create a (class / team product): Experiment on the effects of caffeine on individual students, i.e. Red Bull
Multicultural and/or ESL and/or Bilingual Link: Name a drug common in other cultures
Mathematics/Science Link and/or Humanities Link: Statistical outliers- such as Len Bias— discuss how some individuals will respond differently to drugs
School-to-Career/Tech Prep Link: Chemical Engineering

4. Laboratory Explorations in Biology Students in this program identify a research problem, develop a testable hypothesis, search the literature for relevant information (including the Internet), design a study with adequate controls, collect, organize and interpret their data, write a conclusion (summary) of their research and then present it to other students and the teacher for analysis of how well it is done. The student presentations are usually videotaped for later reference and also are used as model tape to introduce the LEIB to new students.
