I will add a section to the bottom of this article giving a little more information about acids and bases and how you can help your kids understand the difference.

We had to wash our trays a couple of times as we kept testing solutions to keep everything separate! (2009). Basically anything liquid or that can be mixed with liquid to create a solution. After drying she put few drops of given sample solutions (i)- (iv) on these strips. § Make turmeric paper by depositing turmeric paste on blotting paper/filter paper and drying it. *Note: You might be surprised at how many things are acidic. When dry, cut it into strip for testing the solutions. This hands-on activity will allow them to predict, observe, record and discuss, or present their findings. When it dried, you could feel the small granuals of the spice, and the color stayed really vibrant! (a) To make turmeric paper Make a thick paste of turmeric powder (20 g) in distilled water, Apply this paste on a filter/blotting paper thinly with a brush. (Ferri, B.H., Ferri, A.A., Majerich, D.M., Madden, A.G., 2016; Hearns, Miller & Nelson, 2009; Hillman, 2011). Set the filters aside to dry- either hang them up or just set them on a cookie sheet or tray. Do you have any questions? Using both baking soda and vinegar causes the paper to change back and forth between yellow and red. Were you surprised by any of the results? The pH measures the presence or absence of hydrogen ions. Next, use a blender or hand blender until it turns to liquid. Is there anything else you would like to know? If done with gentle household items like vinegar, lemon juice, baking soda, etc. Litmus paper is a type of pH paper made by treating the paper with natural dyes from lichens. Then explain what you are going to be doing- deciding which solutions are acids and which are bases. However, they will still have the opportunity to predict, observe, discuss and explain what they did and what they found. Nearly every liquid is either acidic or basic in nature.Acids are molecules that release hydrogen ions (H+) when dissolved in water.Bases release hydroxide ions (OH-).The pH scale is a way of measuring and precisely specifying how acidic or basic a solution is. Cut thin strips of the yellow paper obtained. (2011). Is there anything more you would like to try or test? *Allow it to dry. Top: Base turned the strip red; Bottom: Acid turned the strip back to yellow. They may want to see if they can find the exact amount of vinegar to make the baking soda react. To make cabbage juice, rip up 5-10 cabbage leaves and place them into a blender. https://files.eric.ed.gov/fulltext/EJ1121997.pdf, Hearns, M.K., Miller, B.K. Write that observation down somewhere so you can keep track of which solutions are basic and which are acidic. I was the kid who asked for a chemistry set for Christmas and spent hours randomly mixing things in my bedroom. Blue litmus paper turns red when a solution is acidic; red litmus paper turns blue in basic solutions.

If you watched the video, you’ve already seen the other chemistry you can try with turmeric: it can be used as an indicator to help us spot the difference between acids and alkalis. Anything below 7 on the pH scale is acidic, and anything above is alkaline (basic). RESULTS Turmeric extract was found to be highly cytotoxic to normal human lymphocytes, to human leukemic cells and to Dalton's lymphoma cells (Table 1). The base in this experiment is the Windex which contains ammonia. Raid the fridge, cabinet, and bathroom for ideas! It can be great for children to create experiments. The effects of hands-on learning versus learning by demonstration on memory in community dwelling older adults (Doctoral dissertation, The University of Toledo). While the added starch particles are small and colorless. Try testing window cleaner, toilet bowl cleaner, orange juice, and apple juice—pour a little of each into separate test tubes or small glasses or jars. Bases (Basic Solution): A substance that can accept a hydrogen ion and has the pH of more than 7. Make sure it’s well mixed. Do you notice any difference between the various pieces of paper (if you’re using different ones)? For example, they might want to see if a frozen baking soda ball reacts faster with vinegar than dried baking soda ball.

To make orange, we sent a few carrots through a kitchen juicer to separate all the juice from the pulp. While the filters are drying, gather the rest of your supplies. Use your wooden spoon to push the fabric down into the dye, trying to coat it evenly. Hands-On Learning versus Learning by Demonstration at Three Recall Points in University Students. Natural Indicator is a type of indicator that can be found naturally and can determine whether the substance is an acidic substance or a basic substance. Objective 6 II.Introduction 8 III.Theory 9 IV.Experiment 1 10 V.Experiment 2 11 VI.Experiment 3 12 VII.Result 13 VIII.Conclusion 14 IX.Bibliography 15 i C B S E . Baking soda water is a good base. Required fields are marked *. Now that you have all of your supplies, let’s get this experiment started! Your secret message remains golden yellow when you spray the Windex with ammonia on the paper, while the rest of the paper will turn red. In the latter half of the 20th century, curcumin was identified as responsible for most of the biological effects of turmeric. My son also enjoyed painting it with baking soda water and then going back over it with vinegar. In this post, we will explore the use of natural pH indicators in this acid and base experiment.
