This week, Primary 5 made some explosive discoveries!
In teams, we had made model volcanoes with Miss Mulholland. Next, we had to put on our Science hats and do some investigating – which combinations of materials (such as Mentos, cola, vinegar, bicarbonate of soda, washing up liquid) would create the most explosive chemical reaction?
We worked in teams to test different combinations and then fed back to the rest of the class. It seemed the most effective combination was vinegar and bicarbonate of soda. So, we prepared our volcanoes for the imminent explosions and added a touch of food colouring to make the liquid more ‘lava like’. Here are some of our explosions below.
We are looking forward to seeing what our next mini-project with Miss Mulholland will be!
Until next time…
Primary 5 & Miss M 🙂
