Today some of the children in the discovery room wanted to make an explosion. We decided to try and make one using lemons and tangerines. We placed the orange and tangerine onto a plate and then took the tops off and squished the insides of the fruit to bring out some of the juice. We then squeezed some washing up liquid into the juice and added some food colouring and a teaspoonful of baking soda. After we did this, we watched as the fruits exploded with colourful bubbles! It was so exciting!!
We talked about the science and how the experiment worked. Citrus fruit contains citric acid which has a chemical reaction when it mixes with the baking soda due to form carbon dioxide, which is a gas. Once the citric acid and the baking soda have neutralised each other the reaction stops and no more gas is made. The children had so many things to say about the experiment including:
“ I think the lemon has more citrus acid in it than the tangerine because the lemon has bigger bubbles”
“I want my explosion to be rainbow colours”” Look the blue and red has turned black”
“I need more baking powder I want a big explosion “ “ It feels slimy if you touch it” “The lemon smells nice”
This week the toddlers have been extremely busy. After enjoying home grown vegetables for snack this week, they decided to make some yummy blueberry muffins to enjoy for snack.
We all washed our hands and found a recipe book to let us know what ingredients we needed.
This is what we needed:
We put all of the dry ingredients into a bowl, flour, sugar, baking powder, lemon rind and salt and gave it a stir.
Now we had to mix the wet ingredients, buttermilk, eggs and melted butter.
And gave it a good stir.
We carefully added the wet ingredients to the flour mix and gave it a good mix. It became very gloopy!
The children took great care filling the muffin cases before putting them in the oven to cook.
The muffins looked delicious when they were cooked. The children had to wait till they had cooled before enjoying them for snack.
Some of the children wanted to taste some of the blueberries…. even the lemon!
What will we make next time?
This morning the children were given all the ingredients they needed to make their own little pizza for snack.
First we put on the yummy pizza sauce.
Next comes the cheese
Helen took our pizzas away to put them in the oven. We have to wait till they were cooked before we could enjoy them. They weren’t too hot.
Have fun making your own pizzas at home. You can add any toppings you like.
