Some examples found on TurnstallTimes' post:
- "Word bottles" are filled with pasta, sand or other materials, with words hidden inside. Students shake the bottle around and read/record the sight words that are revealed. She even included a sheet for students to record the words they find!
- The "magnetic" bottle is full of tiny metal objects along with tons of confetti. Students move a magnet along the outside of the bottle and watch the metal objects react.
- The "ocean bottle" makes waves when the oil, water, and blue food coloring inside are shaken.
Familylicious also has several nice discovery bottle examples posted, like:
- Vegetable oil mixed with powdered color and water mixed with food coloring can be shaken up to create secondary colors, and then separate into two different colors when left still.
- "Density bottles" are filled with different types of liquid, such as water in one and clear shampoo in another. A marble is placed inside each and students shake the bottles to see how the marbles move differently. This would be a great way to introduce the concept of density to the whole class.
- A 'hidden objects" bottle is one of my favorites. This would be great as a free-time activity! Fill a bottle with material, such as sand or tissue paper. Add 5-10 small objects and shake it so that they are hidden. Include a sheet with pictures of the small objects so students can know what each item looks like, then challenge them to find them all.
What other concepts can you showcase inside a discovery bottle?
