“Myths of Science Quiz” 1. Science is a system of beliefs. 2. Most scientists are men as males are better at scientific thinking. 3. Scientists rely heavily upon imagination to carry out their work. 4. Scientists are totally objective in their work. 5. The scientific method is the accepted guide for conducting research. 6. Experiments are carried out to prove cause and effect relationships 7. All scientific ideas are discovered and tested by controlled experiments 8. A hypothesis is an educated guess 9. When a theory has been supported by a great deal of scientific evidence it becomes a law. 10. Scientific ideas are tentative and can be modified or disproved, but never proved. 11.

Mysterious Journeys in the Life of a Raisin Observations and Inferences

Objectives 1. Collect and record data by making observations. 2. Analyze and interpret information by detailed observations and accurate measuring. 3. Communicate valid conclusions.

Engagement Observe: What similarities and differences are there between these two cans of soda? Make observations about the cans of soda using a Venn diagram: How are they similar? How are they different?

Engagement activity: Procedure Make observations about the cans of soda using a Venn diagram: ◦ How are they similar? ◦ How are they different? Regular Coke vs. Diet Coke

Engagement Predict: What will happen when a can of Coke and a can of Diet Coke are each placed in water? Make a prediction with your group.

Safety First! In the lab: ◦ Goggles must be worn at all times! ◦ Never eat or drink anything during labs unless instructed to do so. ◦ Always be careful when moving around the room. No horseplaying allowed. ◦ If there is a spill, notify your teachers immediately.

Exploration: Mysterious Journeys in the Life of a Raisin PART 1 Pour 120 ml tap water into the 250 ml beaker. Add 1 teaspoon of baking soda. Add several raisins. Add 15 ml vinegar. Observe what happens for several minutes. Record your observations on part I of your lab sheet. Add another 20 ml vinegar, record observations.

Part II On your lab sheet under part II: Make a drawing that shows what happened to the raisins in the liquid. Be sure to label the important parts.

Part III & IV Work with your group members to answer the questions within your packet under parts III and IV. First read the examples, then answer the questions that follow.

Table Talk Take a look at the cards on your table. With your group, put them in chronological order. Think about what you saw when each of the steps occurred.

Now Let’s Share with the Entire Class! Each group will be assigned one of the steps. One member of the group will be called on to present and explain it.

Handout What does it all mean? What is an Observation? What is an Inference? Complete the ‘Observation – Inference’ Handout and be prepared to share your responses with the class!

Quiz Time Show me what you have learned! You will have 10 minutes to finish the quiz. Do your best!

5-E Flip Book 1.Match the description with the correct “E.” 2.Check that everyone at your table has the same answer. 3.If everyone agrees, glue the description in the corresponding “E” in the Flip Book. 4.Provide an example of each “E” based on the model lesson.

5-E Lesson Plan Engagement Engagement Exploration Exploration Explanation Explanation Elaboration Elaboration Evaluation Evaluation

ENGAGEMENT What the Teacher Does Creates interest What the Student Does Asks questions such as, “Why did this happen?” “What do I already know about this?” “What can I find out about this?”

EXPLORATION What the Teacher Does Encourages the students to work together without direct instruction from the teacher What the Student Does Thinks freely, within the limits of the activity

EXPLANATION What the Teacher Does Encourages the students to explain concepts and definitions in their own words What the Student Does Explains possible solutions or answers to others

ELABORATION What the Teacher Does Expects the students to use formal labels, definitions, and explanations provided previously What the Student Does Applies new labels, definitions, explanations, and skills in new but similar situations

EVALUATION What the Teacher Does Observes the students as they apply new concepts and skills What the Student Does Answers open-ended questions by using observations, evidence, and previously accepted explanations
