What can you buy for science experiments at Walmart? Buy loads of household chemicals and supplies for labs: isopropyl alcohol (DNA extraction), Dawn, Epsom salts (Magnesium sulfate), washing soda (calcium carbonate), baking soda, vinegar, citric acid, Driveway Heat (calcium chloride), Soil Moist ( polyacrylate crystals), iodine, q-tips, wooden coffee stirrers (wood splints for flame tests), household ammonia, food coloring, cupcake liners (weigh paper), coffee filters (chromatography), plastic paint pallets (reaction plates for 0.1M solutions), craft sticks (stir sticks), magnets (extract Fe from cereal), Elmer’s glue (polymers), Tums (calcium carbonate), sea salt, Alka-Seltzer tablets, borax (polymers), ream of copy paper (concept maps), several packs of paper and pencils (hand to students), colored pencils (sketch slides), construction paper (graphics), multiple colored paper clips (DNA transcription/translation), pipe cleaners and yarn (mitosis/ meiosis), mixed beans (Beanium), and Dixie cups, steel wool, disposable gloves, distilled water, ziplock bags, lighters, candles, camp stove and fuel pellets.
Now for a few links to experiments and activities. Here is a Chemistry link for several chemical reactions with household chemicals, such as sudsy ammonia and Epsom salts. Here are instructions for Ghost Crystals, DNA Extraction, Beanium lab, DNA Structure and Protein Synthesis Simulation, and Alka-Seltzer labs. Don’t forget to shop your kitchen, pantry, desk, bathroom, and garage first before you shop at Walmart!
