The science workshop was really fun. I learned how to make a lava lamp and Goo (known as flubber). All you need to make the lava lamp is a big pop bottle and cooking oil and water and food dye and alkaseltzer. We tried an experiment to see if hot water makes the lava lamp more bubbly. My hypothesis was right: the hot water makes the lava lamp more bubbly. But we also found out… the cold water made it bubble longer!
I wrote down all the ingredients, I wrote down my hypothesis and I wrote down my conclusion. We keep our science books at Niki’s home. First you pour the hot water (or cold water) into the pop bottle (1 dry measuring cup); then you pour the oil up to where you want your lava lamp to be; then you wait for it to settle; then you put the food dye in – what ever colour you want; then you stir it around with a stick (a stick that you can get dye on); then add the alkaseltzer and it will explode (don’t worry – it won’t explode on your table!) – it actually brings bubbles up to the top of your oil and it doesn’t get out of the bottle (you don’t have to have a lid) and it looks really cool – just like a lava lamp!
I was really excited doing it and watching it. I really like hanging out with the other kids at science workshop (2 other girls aged 9 and 10 and one older brother who is 13).
