                    Facts in Three
        Here’s a fun example activity for building
                classroom community…
1. Write down three facts related to you personally-two facts should be
   true, one false.
2. Don’t use facts that others might already know (e.g., I teach 7th grade
   science.)
3. Purpose of the game is for peers to guess the the false fact.
4. Select interesting true facts and create a believable false one.
5. At your table, take turns reading your facts and see if others can guess
   the false one. For example, here are my facts:
    •    My absolute favorite soft drink is Pepsi! Can’t go one day without
         one!
    •    In high school I went on an impromptu date to the opera wearing
         clothes I borrowed without asking from his mom.
    •    My pets include two cats, a dog, a blue tongued skink, and
         two hissing cockroaches.

            Activity or task to assess learners’ prior knowledge and helps them
Engage     become engaged in a new concept through the use of short activities
                      that promote curiosity and elicit prior knowledge.


            Provides students with a common base of activities within which
Explore     current concepts (e.g. misconceptions), processes, and skills are
                     identified and conceptual change is facilitated.


                 Focuses students’ attention on a particular aspect of their
Explain    engagement and exploration experiences and provides opportunities
             to demonstrate their conceptual understanding or process skills.


           Encourages students to assess their understanding and abilities and
Evaluate     provides opportunities for teachers to evaluate student progress
                      toward achieving the educational objectives.


           Challenge and extend students’ conceptual understanding and skills.
Extend      Through new experiences, students develop deeper and broader
                  understanding, more information, and adequate skills.

       Inquiry: What is it?

The inquiry-based classroom is in stark
 contrast to rote learning, memorization
 (merely for the sake of memorization), or
 fact-based learning. In an inquiry-based
 classroom, the teacher does not impart
 knowledge as much as create an
 environment in which students learn for
 themselves through their own
 inquisitiveness and experiences.

       Lesson 11 - Explain

• We are going to read a passage called “A
  Web of Intrigue.”
1. Scan & highlight any vocabulary terms
   from word wall for this unit.
2. How many did you find?
3. Which words were repeated the most?
4. Now read the entire passage carefully.
   Using your highlighter, circle any words
   you encounter that you don’t know.
        Lesson 11 - Explain

Choose an ecosystem. Then, draw a plant
 or animal in that ecosystem in each of the
 circles below. Include and label at least
 one producer, primary consumer,
 omnivore, and secondary consumer. Use
 what you know about food webs to
 connect the plants and animals in the
 ecosystem.
       Lesson 11 - Explain
1. What are some ways in which a food chain
   and food web are similar and different?
2. Explain the ecosystem you drew in your
   graphic organizer. Why did you connect
   your plants and animals the way that you
   did?
3. What do you think might happen to an
   ecosystem if there were no decomposers?
4. How does a food web help scientists
   better understand an ecosystem?

Lesson 12 – The Energy Pyramid

          Hot Seat Vocabulary
• Ask for a volunteer to sit in the “hot seat” in the
  front of the room, with their back to the word
  wall.
• Select a word from the word wall and point it out
  to rest of the class.
• Student in the “hot seat” asks questions of
  his/her classmates to try to guess the word.
