Does lemonade change color? Do children know why? Today, the alpha science classroom unravels the scientific mystery behind Color Changing Lemonade through a children's chemistry science experiment activity, showing children the charm and absence of kid's science experiment activities, understanding simple chemistry knowledge, and falling in love with exploring science.
Alpha science classroom： Color Changing Lemonade，Materials you'll need
clear glass cup
lemon juice (1 1/2 cups)
sugar (1 cup)
cold water (4 cups)
red cabbage juice
Alpha science classroom： Color changing lemonade, step by step tutorial
Step 1: First, children mix 1 cup of lemon juice, 1 cup of sugar, and 4 cups of water in a large pitcher to make lemonade.
Step 2: The children add ice cubes to the glass, and then add some lemonade.
Step 3: The children pour the red cabbage juice into the lemonade and watch the color change! You can add water or sugar to taste.
Alpha science classroom： Color changing lemonade, the scientific knowledge behind
The alpha science classroom teaches children this lemonade chemistry science experiment, and children can surprise their friends! Freeze the cabbage juice in an ice tray. Add ice cubes of cabbage juice to lemonade and watch the color change from yellow to pink when the ice cubes melt! How is this going? Lemon juice is naturally rich in citric acid, and red cabbage juice is an acid-base indicator. When the cabbage juice is mixed with the citric acid in the lemonade, it turns pink, indicating that the liquid is acidic!
Alpha science classroom wants to show children that science is not close to us, and there are many amazing scientific phenomena around us, and there are many in the kitchen. classroom, together with the exploration of more interesting kid's science experiments, grow up to be the most powerful science wizard.
Alpha science toys also specialize in designing many children's chemistry science experiment kits to help children explore scientific knowledge and the magical phenomena behind it, so that children can learn more science knowledge and grow up happily in a joyful way.
