  1. INVESTIGATION: Steps for Making Glue PROBLEM: [Copy.] What skills will I use to figure out the steps to make useful glue? HYPOTHESIS:[Make your own.] MATERIALS: [Copy.] 1 set of instruction papers, 2 beakers, 1 plastic cup, 1 stirring rod, 1 scoopula, 1 funnel, 1 piece of filter paper, 1 watch glass with baking soda on it, 2 graduated cylinders, 40 ml of skim milk, 10 ml of vinegar, 2 small pieces of scratch paper

  2. INVESTIGATION: Steps for Making Glue (continued) PROCEDURE: [[Number from 1 – 9 skipping lines. Work together to put the cards (steps) in order. Try out your order, including gluing the paper together. If it doesn’t work; clean it up and try again. Once you have the steps in the correct order (you tested it out and it worked), write them down.] DATA / OBSERVATIONS: [As you try each step, #s 1 – 9, record a list of organized observations that will help you determine the correct order.]

  3. INVESTIGATION: Steps for Making Glue (continued) DATA ANALYSIS: [Answer these questions: Were there any patterns (repeated occurrences)? Try to put your observations into groups of similar types of observations. What kind of observations helped you decide on the order of the steps? ] CONCLUSION: [Was your hypothesis correct or not? How did you know if it was correct? What could you do differently? Summarize what you learned. ]

  4. Procedures • 1. Pour about 40mL of skim milk into a beaker. • 2. Add about 10mL of vinegar and stir to mix. • 3. Pour the mixture through a coffee filter into the plastic cup. • 4. Use a plastic spoon to scrape off the solid material that collects on the filter.

  5. Procedures • 5. Place this third material into a beaker. • 6. Add a pea size amount of baking soda to the beaker. • 7. Stir to mix. • 8. You have made natural glue! • 9. Try gluing two pieces of paper together to see how well the glue works.
