Ice Cream without a Freezer!

The summer holidays are approaching fast and the high temperatures encourage us to have some fun scientific activities that are also refreshing and perfect for these days. So we’re going to make and enjoy homemade ice cream in just 10 minutes. Basically you need ice, salt, milk and two plastic seal bags (freezer bags, one large and one small). To enjoy the experiment even more, you can add to the …

Making “Ecological” Plastic

When we performed the experiment Milk “solidification”, we mentioned that we saved some of the milk for a second solidification experiment. Today we are going to tell you what this second experiment is about: making “plastic” from milk. Originally we heated the milk without allowing it to boil and then added a tablespoon of vinegar and stirred the mixture. Then, we observed that it began to solidify, forming small lumps. …

Milk “Solidification”

Lately we’re doing science in the kitchen and the thing is we enjoy watching food transform and discovering the origins of some of the typical products in our fridge that we were unaware of. Today we experimented again with milk. We take a liter of milk (better if it’s fresh milk) and heat it up without letting it boil. When it was hot, we added about a tablespoon of lemon …

Milk and Runaway Colors

Today we’ll talk about one of the experiments we made in The Science Week workshops. Again, we used milk, this time to discover more about surface tension and about the behavior of soap in water. First we pour whole milk in a dish. We carefully apply a few drops of food coloring, and we notice that these drops don’t dissolve immediately in the milk and color it as would happen …

Butter in the “lab”

As already mentioned, we celebrated Science Week with kindergarten pupils from the Gaspar de Portola in Balaguer (Lleida) and with pupils in kindergarten and primary from Camarasa-school (Lleida). With the kindergarten and primary school kids, we performed several experiments with milk and enjoyed it, especially for the simple and tasty treat that it was, so I encourage you to try it to. We start by pouring cream in a small …
