Notes de l'éditeur
Materials needed: individual whiteboards, markers, erasers for each student, gallon jug of water, measuring cups in the following sizes: ½ cup, 1 cup, 2 cups
The purpose of this PowerPoint is to have something ready for the interactive whiteboard to use with my second graders this coming year. Identifying bodies of water is one of the second grade science standards. I thought this would be a different way to introduce students to the topic than I had used before. Previously I have used large “flashcards” of pictures from the Internet or National Geographic to introduce the vocabulary and then did an explanation of the different bodies of water. What I like about using the PowerPoint is that I can present the main points of my oral presentation with words on a screen. This way students are getting the information in two modalities. I have the presentation set up so that I have to click my way through it. This allows me to go at the pace of the students and not be bound by the pace I predicted I needed for the slide show. I tried to include audience participation in the introduction, the demonstration, and at the end with the mini-quiz. I also tried to keep it fairly short, so as not to lose the core curricular points in the presentation.
Before starting, I wondered how long it would take to create this type of presentation. It was not as bad as I first thought it would be. The most time consuming part was getting the answers to my interactive quiz to show up appropriately, but now that I know how to do that, the next time would take less time. Also, now that it is done, I have it for future use. I can also share it with other second grade teachers. Since my room is the only second grade room that will have a whiteboard this year, I could bring the other second grade students in my building in to my room to share it with them. It would also be a way to show other staff members how to use PowerPoint with an interactive whiteboard. I am excited to be able to have another way to present material to students.

Have gallon of water and 3 measuring cups – ½ cup, whole cup, 2 cup. After students show answer/guess on whiteboard, pour water into ½ cup measuring cup. Click to highlight answer.
Point out oceans on map. Add that since 2000, there is now a 5th ocean, the Southern Ocean, located near Antarctica.

Use acronym HOMES to remember the names of the lakes. Great Lakes contain the most surface fresh water on Earth. Only the polar ice caps contain more fresh water.
