TRANSCRIPT

Jellies: Day 1By Larissa OstlundRippling Water(Basic)

Note: This video template is optimized for Microsoft PowerPoint 2010.In PowerPoint 2007, video elements will play, but any content overlapping the video bars will be covered by the video when in slideshow mode.In PowerPoint 2003, video will not play, but the poster frame of the videos will remain in place as static images.

The video:Plays automatically after each slide transition.Is 15 seconds long.Seamlessly loops for infinite playback.

To add slides or change layout:To add a new slide, on the Home tab, in the Slides group, click the arrow under New Slide, then click under Motion Background Theme, then select the desired layout.To change the layout of an existing slide, on the Home tab, in the Slides group, click Layout, then select the desired layout.

Other animated elements:Any animated element you insert will begin after the slide transition and the background video has started.

Layouts with video effects:The (Green) Title and Content and (Purple) Title and Content layouts are creating by using a color overlay on the video.With the video selected, under Video Tools, on the Format tab, in the Adjust group, select Color and choose Teal, Accent Color 6 Light (third row, seventh option from left) or Periwinkle, Accent Color 5 Light (third row, sixth option from left).

1Lesson Objective:To become familiar with:Jelly academic vocabularyBody parts and their functions of jelliesThe basic understanding of jelliesWhere have I seen jellies (jellyfish) before?Finding Nemo Video clip:https://www.youtube.com/watch?v=maWVkCSSsq4(copy and paste into a new tab)What are jellies?Jellies are invertebrates that dwell in the seaTheir bodies are gelatinous-lookingArent fishThey belong to the Cnidaria phylumSea anemonescorals

General Information about Jellies: Radially symmetrical

Look at me! Im radially symmetrical!Radial symmetry: If you cut a jelly on the center part of the body, the halves would be the same!

General Information: Swarms

A group of jellies is called a swarmDory and Marlin were stuck in a swarm of jellies! (Just like the man on the right)How many species (types) are there?There are about 1000-1500 species of jelliesThe moon jelly is the most well known species

Epidermis: The outer body parts/cellsBell

TentaclesBell

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

-opens and closes like an umbrellaTentacles: contains stinging cells that paralyze prey

-a stinging cell is called a cnydociteInside 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

Jellies stinging- ACTION!Jellies have thousands of nematocysts on the tentacles, oral (feeding) arms, and on their mouth. Without them, they wouldnt be able to survive!How jellies sting with their tentacles:https://www.youtube.com/watch?v=UoRWvE8LA9U

(copy and paste links in new tabs)Gastrodermis: the inner parts/cellsOral arms

Mouth

Digestive CavityOral Arms

Is a jellys hand. The oral arms bring the food to the mouthMouth

-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 jellys wasteDigestive Cavity

Digestive Cavity

-AKA (the colenteron)-contains: stomach and intestines-where food is digested (like humans)-digested food gives jelly energy (like humans)Lets 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 outVocabulary match up!With your partner, put all of the cards face down. Take turns matching the academic vocabulary with their meaning.ClosureIn 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.Section divider layoutSubtitle Here
