1. Make "creeping material"
Recipe for "Glop"
- Dissolve 75 ml cup Borax in one liter of water and set aside (1:16 ratio).
- Mix equal parts of white glue and water.
- Add several drops food coloring to the glue mixture.
- Measure 50 ml of borax solution and place in a sealing plastic bag.
- Measure 150 ml of the glue mixture and place in a sealing plastic bag.
- Just before using, combine the glue mixture and the Borax mixture, in a 3:1 ratio, seal the bag again and knead to form "glop".
- Mix until the glop has the consistency of silly putty.
- A more concentrated solution of borax will give you a stiffer mixture.
- Store the glop in the sealing bags.
- Refrigerate in sealed plastic bags for long-term storage.
- ***Do not use the fluorescent Elmer's Glue. It is not always successful.
- "Glop" may be mixed and stored in any sealable container.
Recipe for "Oobleck"
Materials: Cornstarch & water
- Pour the water into a cup.
- Add cornstarch a little at a time while stirring.
- Keep adding more water or cornstarch until the Oobleck reaches the desired consistency.
2. Exploration materials setup for each lab station:
- Make a transparency of a metric ruler for each lab setup used. Make sure the metric ruler is in the center of the transparency sheet. It may be best to copy the metric ruler leaving a bit of space above the 0 cm mark for the beaker location.
- Tape the transparency to the back of the clipboard. To make observations easier to make, place a piece of white paper underneath the transparency.
- Rest the clipboard on a pile of wood blocks or other supporting material. The clip end should be resting on the blocks.
- Place the creeping material into a beaker. Cover the top of the beaker to keep the creeping material inside until the exploration begins.
Use masking tape to keep the beaker steady on the clipboard by taping across the beaker onto the clipboard. The lip of the beaker should be on the tape at the 0 cm mark of the transparency.
