Today we searched through the science book together to choose which experiment we would like to explore. We decided on the Potion Lab.

“This one looks fun”

“ It’s the best”

“ I am excited will ours look like that”

We took turns to gather all the materials and set them on the table. Before we started we made some predictions what do you think will happen if we mix vinegar and bicarbonate of soda. A few of the children made predictions.

“Bubbles
“Sparkles”

“ it fizzes”

“Magic potion”

First of all we added vinegar to make it half full. We then used our fine motor skills and chose between a droplet or a syringe to squeeze in some food colouring. We used our pincer grip to add some glitter and then added a large spoonful of bicarbonate of soda. We then mixed the potion and watched for the reaction of the ingredients mixing together. The children were curious and stayed focused throughout the experiment sharing their thought and ideas.

“ it’s working

“Wow it’s fizzing”

“It’s nearly at the top”

“Bubbles”

“Let’s do it again.

“ bath foam like my bath”

“It’s going to explode”

“Look at this potion”

“ The colours are mixing together and changing colour.

“ it’s so cool”

.The children were fascinated by the reactions and they continued to try out their own experiment using a variety of small and big jars and adding different amounts of ingredients and watching their own eruptions. Lots of fun and laughter was had

We came to the conclusion the best and foamiest experiment was adding fairy liquid to it.
“ can we do this one everyday?”

This morning our little scientists have been carrying out more experiments and making predictions about the outcomes. We are learning about forces and describing their effects.

We started by filling three glasses- one with still water, one with fizzy water and one with super fizzy limeade. We then made predictions about about what would happen if we put a raisin in each of the glasses.

We then dropped the raisins in the glasses to test our predictions and were amazed by the results.

Through a previous bubble experiment, we have learned that bubbles have air called carbon dioxide in them. It is these bubbles that are attaching on to the raisins and making them float but when the bubbles pop the raisins fall back to the bottom as they are denser and heavier than water. This makes the raisins look like they are dancing. We then continued to add more raisins and discovered that the smaller ones were lifted up by the bubbles more easily.

”The bigger ones are heavier and they just make the bubbles pop.”

If you have some sparkling water and raisins in the house, please try this at home and share your findings with us @cartmillcentre
