1 Data Sheet for Task 1: Mixing It Up! 1. Mix 25 ml water and 1 ml of Mystery Material A in a small container. Then mix 25 ml water and 1 ml of Mystery Material B in another container. Put the lids on and shake them well. Mystery Material A Observations Conclusions Physical mixture (heterogeneous) or Solution (homogeneous)? Mystery Material B 2. Use a coffee filter, the funnel, and a beaker to try to separate the mixtures from the water. Mystery Material A Observations Conclusions Mystery Material B I think Mystery Material A may be because I know that. I think Mystery Material B may be because I know that. Use the toy parts to construct a 3-D model of each mixture that would explain the difference between the physical mixture and the solution. Draw and label a diagram of your model below. Mystery Material A Mystery Material B
2 Data Sheet for Task 2: Mixtures and Mass 1. Create a trail mix using 3 ingredients. The sum of the mass of the ingredients before they are mixed should equal 100 grams. Mix the ingredients and measure their combined mass using the balance scale. Ingredient #1: Ingredient #1: Ingredient #1: Sum of the mass of all 3 ingredients Mass of trail mix AFTER mixing BEFORE mixing Mass = g Mass = g Mass = g 100 g Draw a diagram that represents your findings. 2. Use the digital scale to measure the mass of 1 level tablespoon (15 ml) of drink mix. Then measure the mass of 1 cup of water. Mix the drink mix with the water. Weigh the combined mass of the solution. Don t forget to subtract out the mass of the containers. Mass of drink mix: g Mass of water: Predicted mass of solution: Actual mass of solution: Draw a diagram that represents your findings. 3. Place a beaker with 200 ml water on the digital scale. Record the mass on the chart below. Now place 2 Alka Seltzer tablets on the scale next to the beaker. Figure out the mass of the tablets and record it on the chart below. Predict the mass of a solution of the water and the Alka Seltzer. Record it. Then put the Alka Seltzer in the water. After it finishes fizzing, record the mass of the solution. Mass of 200 ml water and beaker: g Mass of 2 Alka Seltzer tablets: Predicted mass of Alka Seltzer solution: Actual mass of Alka Seltzer solution: Was the mass of the solution what you predicted? Draw a diagram that explains your findings.
3 Data Sheet for Task 3: Concentration and Dilution 1. Label 3 clear cups with a different symbol for each. Make a key on the index card, showing which symbol stands for 1, 2, or 3 teaspoons of drink mix. Add 100 ml of water to each cup and the corresponding number of level teaspoonfuls in each. Trade cups with a different group. Pour a sample of each solution for each group member to taste test in his/her personal cup. Make observations based on color and taste to determine which solution is which. Check your answers on the index card. Symbol Color Taste Concentration (1, 2, or 3) How does changing the amount of solute affect the concentration of the solution? Draw a diagram that explains your findings. 2. Put 2 tsp of drink mix in each of 3 clear cups. Label one cup 100 ml and add 100 ml of water to that cup, stirring to dissolve the drink mix. Label a second cup More and, without adding more solute, find a way to make it MORE concentrated than the first one. Label the third cup Less and find a way to make it LESS concentrated than the first one without adding more solute. Pour a sample into each team member s personal cup to taste test. Draw a diagram to show your work. Label the amount of solute and solvent in each. More 100mL Less More Concentrated Less Concentrated/More Dilute 2 tsp solute 2 tsp solute 2 tsp solute ml solvent 100 ml solvent ml solvent Based on the observations and data collected in these two activities, list two ways to make a solution MORE concentrated: Give an example of a time when you might need to make a solution more concentrated. Give an example of a time when you might need to make a solution less concentrated (more dilute).

Manipulated-Independent variable (the only one I will change): I will measure the responding variable by Testable Question #2: How does affect the rate of dissolving? Manipulated-Independent variable (the only one I will change I will measure the responding variable by.

Manipulated-Independent variable (the only one I will change I will measure the responding variable by.
6 Data Sheet for Engineering Mixtures: Separation Anxiety Explore the properties of the following materials and fill in the chart below. Particle Size Density: Will it float? Magnetism: Is it attracted to magnets? Salt Powder Iron Filings Styrofoam Gravel Solubility: Will it dissolve in water? In Ziploc bags, make 3 identical mixtures, each with the amounts in grams shown in the chart below. Gravel Powder Iron Filings Styrofoam Salt Starting Use the materials in your tub to find the most efficient way to separate your mixture. Follow the engineering design process to brainstorm procedures, design, test, and revise. As each substance is separated, place it in one of the courtesy cups and measure its mass in grams on the digital scale. Refine the steps using your 2 nd and 3 rd bags of mixtures. Fill in the chart with the amounts you collect. TEST 1 Gravel Powder Iron Filings Styrofoam Salt Number order (1-5) and method used Percentage (divide amount recovered by starting amount) TEST 2 Gravel Powder Iron Filings Styrofoam Salt Number order (1-5) and method used Percentage (divide amount recovered by starting amount) TEST 3 Gravel Powder Iron Filings Styrofoam Salt Number order (1-5) and method used Percentage (divide amount recovered by starting amount)
7 Conclusion: Draw a diagram to show the most efficient method you used to separate each substance. Number them in the order in which you separated them. Diagram Salt Powder Iron Filings Styrofoam Gravel Number order
