Let’s Get Started: Making SlimeName:______________________Hour:_______Date:___________Science 8Introduction: Scientists use specific steps to solve problems and carry out investigations. In thisintroductory activity you will be making a polymer(Slime) by using the steps of the scientific method.It will be your task to determine the best amounts to use for each the ingredients used to produce Slime.Step 1:Identify the Problem: (What is the question you are trying to answer?)Which of the following combinations of borax solution and glue solution will produce the best slime?1. 20 mL of borax, 40 mL of glue2. 40 mL of borax, 20 mL of glue3. 40 mL of borax, 40 mL of glueStep 2:Hypothesis: (develop as probable answer for the question you are given, Write hypothesis as a sentence!)If we use_____________________________________________________than__________________________________________________________________________________________________________________.Step 3:Experiment: (process or steps you will use to test your hypothesi)A. Materials:1. glue solution 5. graduated cylinders2. borax solution 6. paper cups3. food coloring 7. ziplock bag and marker for your best slime4. wood stirring sticksB. Procedure:1. Carefully measure 20 milliliters of borax solution into a graduated cylinder. Pour this into one ofpaper cups. If you want your slime to be colored, add 1-2 drops of food coloring into the boraxsolution and mix with a wood splint.2. Next, using another graduated cylinder measure 40 milliliters of glue solution. DO NOT USE THESAME CYLINDER FOR BOTH THE GLUE AND BORAX! Add this glue solution to the boraxsolution you already have in the paper cup.3. Use the wood splint to mix the glue and borax solutions together. After mixing for about 1 minute,pull out the solid portion of the mixture from the cup and work it together with your hands. (Youmay want to return it to the cup and see if the mixture will absorb any more liquid, and mix togetheragain.)4. As you mix the solutions together, check to see how well it flows by holding it in the air. See if itbreaks easily and cleanly. Notice whether it sticks to your hands. List all these observations and anyothers in the data table.5. Return your slime to its cup and set aside while you mix the other combinations.

6. Repeat steps 1-5 using a 40 mL borax and 20 mL glue. Be sure to compare the qualities of this slime toyour first trial. Record these observations and comparisons in the data table.7. Repeat steps 1-5 using a 40 mL borax and 40 mL glue. Be sure to compare the qualities of this slime toyour first 2 trials. Record these observations and comparisons in the data table.8. Hold up and compare all three combinations used to make slime. Decide which of the combinationsyou feel produced the best slime. Put this slime in a ziplock bag and mark the bag with the names ofyour group members and which combination of borax and glue were used to produce it.The other 2 combinations used can be thrown in the garbage designated in the front of the classroom.9. The graduated cylinder should be rinsed out and turned upside down to drain.Carefully wipe your lab station and return all materials to the lab tray provided.Step 4:Observations and Data: ( Information you collect related to the questions you are attempting to answer.)( Could include charts, collected data values, graphs of data collected…….)1.2.3.Borax and Glue Ratio20 mL borax40 mL glue40 mL borax20 mL glue40 mL borax40 mL glueObservations of Slime produced:what does it look like, how does it flow, does itbreak cleanly, does it stick to hands……BE SPECIFIC3-4 observations required for each trial……..Describe comparisons between different results…...1.2.3.1.2.3.1.2.3.Step 5:Conclusion: (judgement related to the hypothesis and original question)Must Include: 1.
