Quiz #1 on EPA pgs. 2-6.
Have students read the clam shrimp article (either for homework the previous day or the start of the period). Have students make a vocabulary list of words they are not familiar with.
- Ask students if they know what a clam shrimp looks like. Show a picture of a clam and one of a shrimp. Have students try to draw a picture of what they felt a combination of the two would look like.
- Show a picture of a clam shrimp sketch.
- Show a picture of a real clam shrimp and indicate where the head, thorax (middle), and abdomen (back) sections are and have students label their picture. Give students a picture of the clam shrimp to tape to their worksheets.
- Have students read the clam shrimp article and ask “What types of animals eat the clam shrimp?”
- Ask “What types of animals do clam shrimp eat?” Here you can go over unicellular and multicellular organisms.
- Go over producers (autotrophs); herbivores; carnivores; and omnivores (heterotrophs).
- Review what a food chain is – the relationship between feeding organisms.
- Hand out “Discovery Trail” worksheet.
- Show a picture of a pond food web and explain that they are several food chains that are interconnected.
PART II - Pond Web activity
- Present the Pond Web activity for group work.
- Assign groups and have students take out packet and review materials.
- As a class, but still remaining in groups, go through the different steps of the activity step by step (Especially if this is the first group activity for class).
- Have students work together to answer questions.
- Using the large pictures of animals with the packet, have the class create a food web together for posting on a bulletin board.
Part III– Student observation of Pond Water
- Start going over micro-organisms that can be found in vernal pools using water from the tanks– taken from Lesson – POND WATER – A CLOSER LOOK (optional) – use student activity sheet used in this lesson
- Describe the procedure to retrieve sample from the Tank
- Stir sediment in tank.
- Fill a cup with tank water.
- Filter into a large jar using a fine mesh.
- Place clear aged tap water (or distilled water) into a petri dish
- Empty contents left on mesh into the petri dish containing water.
- Place a Petri dish of pond water under a dissecting microscope and focus using the fine and course adjustment knobs.
- Have students answer the question corresponding to the previous activity above on the student activity sheet.
- Fill out your index of organisms for two different organisms that you are able to identify using the guide provided to you.
- Discussion questions on back of worksheet.
Higher level supplement
- Read EPA seasonal pool text pgs. 10 – 15 section 2.2 Life Zones of seasonal pools and 2.3 Life Histories of Seasonal Pool – Dependent organisms and do Cornell notes
- Students are asked to create a food web using animals discussed in clam shrimp lesson.
- Complete index of organisms
