  1. Jellies: Day 1 By Larissa Ostlund

  2. Lesson Objective: To become familiar with: Jelly academic vocabulary Body parts and their functions of jellies The basic understanding of jellies

  3. Where have I seen jellies (jellyfish) before? Finding Nemo Video clip: https://www.youtube.com/watch?v=maWVkCSSsq4 (copy and paste into a new tab)

  4. What are jellies? • Jellies are invertebrates that dwell in the sea • Their bodies are gelatinous-looking • Aren’t fish • They belong to the Cnidaria phylum • Sea anemones • corals

  5. General Information about Jellies: Radially symmetrical Look at me! I’m radially symmetrical! Radial symmetry: If you cut a jelly on the center part of the body, the halves would be the same!

  6. General Information: Swarms A group of jellies is called a swarm Dory and Marlin were stuck in a swarm of jellies! (Just like the man on the right)

  7. How many species (types) are there? There are about 1000-1500 species of jellies The moon jelly is the most well known species

  8. Epidermis: The outer body parts/cells Bell Tentacles

  9. Bell -creates overall movement -makes the jelly move up and down; only movement it can control -*In Finding Nemo this is what Dory and Marlin were bouncing on -protects the internal structures Bell -opens and closes like an umbrella

  10. Tentacles: contains stinging cells that paralyze prey -a stinging cell is called a cnydocite Inside a cnydocite, there is a nematocyst. It is a coil thread stinger that comes out of the cnydocite. This is how the tentacles paralyze the prey

  11. Jellies stinging- ACTION! Jellies have thousands of nematocysts on the tentacles, oral (feeding) arms, and on their mouth. Without them, they wouldn’t be able to survive!

  12. Gastrodermis: the inner parts/cells Oral arms Mouth Digestive Cavity

  13. Oral Arms Is a jelly’s “hand.” The oral arms bring the food to the mouth

  14. Mouth -is where food enters the body (just like us) -located between the oral arms -unlike us, the mouth serves another function: it also gets rid of a jelly’s waste

  15. Digestive Cavity Digestive Cavity -AKA (the colenteron) -contains: stomach and intestines -where food is digested (like humans) -digested food gives jelly energy (like humans)

  16. Let’s Label our jelly! -each elbow partner pair will get a bag of vocabulary words -sort words and place them on the boxes on your worksheet -be ready to share answers -we will complete it together after sharing out

  17. Vocabulary match up! With your partner, put all of the cards face down. Take turns matching the academic vocabulary with their meaning.

  18. Closure In your science notebooks: 1. sketch and write one thing you learned 2. write one part of the jelly that is similar to the function of a body part of another animal/human.
