4. Density Lava Lamps
To make a density lava lamp fill a plastic bottle with the following liquids: Clear corn syrup, water with a few drops of food coloring, and layer of vegetable oil. Be sure to leave a space at the top of the bottle. Wait until the liquids settle then add in a tablet of extra strength alka seltzer. Watch as the alka seltzer and water react and bubble up through the oil layer. To see this in a step by step videocheck out this video(Pssst this is one of our students!!!)
6 . Color Mixing
Pour water into three clear plastic cups, then add blue, red, and yellow food coloring to each. Have an additional cup full of uncolored water available as well. Give your child an empty ice cube tray and pipettes and let them create different colors by mixing different ratios of two different primary colors in each ice cube compartment. The secondary colors are new colors created from two primary colors. This is a simple visual of how chemical reactions work.
Most liquids are either an acid or a base. Liquids with lots of hydrogen ions in them are considered acids. Liquids with many hydroxide ions are bases. Scientists use a scale called the ph scale to measure how acidic or basic a liquid is. The more hydrogen ions in a liquid the more acidic it is and ranks low on the ph scale. The more hydroxide ions...
Carbon is the most important element for life. Chemicals that contain carbon are called organic compounds. Carbon has two main forms: The first is in the hard form of diamonds and graphite, and the second is the impure form found in charcoal, coal and soot. SAFTEY WARNING: Carbon reactions are always fascinating to watch however the presence of fir...
Chromatography is the process of separating mixtures. We usually think of it in terms of color hence the prefix -chroma, however in chemistry is means simply a method of separating mixtures by letting them slowly move past each other. It applies to both liquids and gasses. This is wonderful in-depth explanation of chromatography.
Colloids and Solutions are two types of homogenous mixtures. 1. Colloidsare mixtures in which a small particles of a substance are suspended throughout another substance but not chemically bonded. They are stable though and do not separate. Examples of colloids are gelatin, butter, mayonnaise, fog and smoke. 2. Solutions are mixtures in which the p...
A polymer is a substance made up of a long chain of molecules. Polymers are typically flexible materials like plastic or gum. The classic polymer kids LOVE to make is slime! Glue is already a polymer but when combined with sodium tetraborate (borax ) the protein molecules of the glue and the borate ions crosslink, making it harder for the molecules...
Crystals are a type of material that is formed by patterns of repeating molecules. There are four types of chemical bonds in crystals and therefore four categories of crystals. These are: Covalent, Molecular, Metallic, and Ionic Crystals. You can grow crystals by mixing up a super saturated solution (usually with a type of salt and water) and letti...
Alright you guys, do you feel like you have some good project ideas for exploring chemistry with kids? Many of these will make greats science fair projects. Be sure to start with them as a topic then start asking questions, form a hypotheses, and do some experiments. Now I have to admit that I really fell in love with chemistry projects as an adult...
