GQ......
1. How is a frog, a worm and a grasshopper adapted to live in their environments? Make a list of three adaptations for each.
2. Make a list of things you already know about a frog, a worm, and a grasshopper. (3 each)
3. Make a list of questions you have for each of them. (At least 2 each)

6 kingdom classification

Shape of Life: Phyla

Classification of Living Things

Class. Questions & Foldable

Taxonomy Rubric

Step 1: Watch the 6 Kingdom Classification Video and fill out the worksheet as you go.
Step2: Click on the Shape of Life: Phyla link and research the main 8 body systems while also filling out your worksheet.
Step 3: Watch the Classification of Living Things: You will then make a foldable for your assigned animal that you will be dissecting. Follow the directions on your worksheet. You will research the taxonomy of the grasshopper, frog, or earthworm.

Learning Targets:
1. Investigate how scientists classify living things.
2. Research and classify your own living organism.

Natural Selection Test

I will come around and tell you which test questions you missed. Make a list by writing down the numbers and use the link above look over the questions. You may get points back if you correct your multiple choice answers and hand them back to me. Use complete sentences and tell me why you missed it.

Step 3: GQ page 77
1. What is the purpose of Meiosis?
2. What are three main differences between Mitosis and Meiosis?
Step 4:
Self assess your Quizzes.
Step 5:
Look at the slides for Meiosis under the microscope. Start with the Plant Meiosis 1, Plant Meiosis 2 and then onto the animal Meiosis.
Step 6:
Click on the link for sexual and asexual reproduction and investigate how each organism reproduces. And then also watch the sources of variation video. As you watch the video, list the possible sources of variation in organisms.

Sexual & Asexual Reproduction

Sources of Variation video

Learning Targets
1. Develop and use a model to describe why asexual reproduction results in offspring with identical genetic infromation and sexual reproduction results in offspring with genetic variation.
