The Egg-Cola Science Experiment is a great unit for reminding students of the importance of brushing their teeth. A hardboiled egg is placed in a plastic cup of cola and is left overnight to stain. Students are invited to predict what they think will happen to the egg overnight. The next day they witness the magical cleaning powers of an ordinary toothbrush and toothpaste. If it works for the egg, it will work for your teeth too!
This animated PowerPoint science experiment is part of an ongoing series of recipes, crafts, poems, songs and science projects designed to serve as a vehicle for reinforcing literacy in the classroom. Although content was originally designed to capitalize on interactive whiteboard technology, the files work beautifully with the free Microsoft PowerPoint app for the iPad. Now the Animated Step-by-Steps can be more easily used in activity centers or individual therapy sessions (SlP, OT). Visit the Animated Step-by-Step blog (www.animatedstepbysteps.blogspot.com) for specifics on how to get your Step-by-Steps ‘up and running’ on your iPad.
In addition to the obvious emphasis on literacy, numerous early math concepts can be easily incorporated as ‘teachable moments’. The series is equally beneficial and engaging for classrooms serving regular and/or special education students. Students learning English as a second language can also benefit from these unique resources.
• The step-by-step text is simple and consistent across recipes/crafts.
• Steps have been distilled into smaller components to make them less overwhelming for beginning readers and students with special needs.
• Each PowerPoint slide presents a single step with several embedded animations
designed to help all students better understand the step requirements.
• Animations are designed to support and visually reward reading and promote language comprehension.
• Stars appear in the text, signaling when an animation should to be inserted.
• Animations are typically slow to promote visual tracking in several directions.
• Photos are clear (no background distractions) and uniform across recipes, thereby promoting consistent picture-word-text associations.
• Each PowerPoint slide includes an image of the final product thereby providing a constant reminder/reference for what is being assembled.
• Sound effects accompany all key animations to reinforce a deeper understanding of actions and are designed to include individuals who are visually impaired.
• The task of activating animations is typically shared by students (by coming up to the interactive whiteboard to tap or by using a remote switch) or can be assigned to a single student undergoing training in switch use.
• Space has been allotted between the text lines to allow classroom staff to add picture symbols to the document to support an AAC agenda for students with Complex Communication Needs. (.pps file must be converted to .ppt or .pptx file to add symbol graphics)
• Allows differentiated instruction. Although the steps are presented using simple visuals of fractions (i.e., numerator directly over denominator) and avoids using cooking abbreviations, pages have a multifaceted star in the upper left corner that will allow you to quickly check the recipe amounts. This page presents slash fractions (e.g., ½) and abbreviations (e.g., tsp for teaspoon; tbsp for tablespoon) to accommodate the needs of students that are more advanced.

This file was created using PowerPoint 14.3.5 but appears to function fine on earlier versions of PowerPoint. Please note the downloaded file is a read only PowerPoint Show file (97-2004). It should be compatible with PowerPoint versions 97 to current.
Bloom is committed to providing students and teachers with creative and engaging materials designed to promote differentiated instruction that is beneficial for all students.
