In the Foil Etching experiment we had copper burn a whole in the aluminium foil. As you can see, aluminum Al is much more reactive than copper Cu, but nothing … Continue reading MEL Chemistry Experiments: Foil Etching, Magnetizing Magnesium, Metal Contest
Today we have made beautiful rainbow chrystals! Polarized light iridizes sodium thiosulfate crystals, so we made the crystals in between two polarizing films and then observed them through the microscope. … Continue reading Chemistry Experiments: Polarized light iridizes crystals
We did two more experiments a couple days ago: Liquid Wires (creating a simple circuit using graphite and liquid glass, a sodium silicate solution) and making our own Zinc-Carbon Battery, … Continue reading MEL Chemistry Experiments: Making Batteries
Monday was a chemistry day as we went to the post office to fetch our brand new delivery from the MEL Science subscription! We set a record of 6 chemistry … Continue reading MEL Chemistry Experiments: Flames and Minerals
We used electrolysis (with sodium hydroxide NaOH solution as the basic medium) to produce oxyhydrogen and extinguished the candle by means of the reaction between hydrogen and oxygen. When electrolyzed, water decomposes … Continue reading A booming start of the year
Our new MEL Chemistry box arrived, containing tons of color fun! We have already tried two experiments. In the Color changing milk experiment, the soap touches the milk creating a very thin … Continue reading Chemistry Experiments: Colors (surface active agents and pH indicator)
Our third MEL Science box arrived back in August, when we were on vacation. We have already tried two experiments from the box, both perhaps more suitable for winter. Instant … Continue reading MEL Chemistry Box number 3: Artificial Snow and growing crystals on a Xmas tree
Today we opened our second MEL Chemistry box with two experiments using tin (Sn). We made a tin dendrite and grew a tin hedgehog. Both experiments involved preparing a tin … Continue reading The second set of MEL Chemistry experiments
We have received our first MEL Chemistry box, something the kids were really impatient to start. And guess what, finally something to be proud of being a Russian from St.Petersburg … Continue reading Our first MEL Chemistry set has arrived!
