Second Milk Experiment

The second experiment involved tea, lemonade and orange juice.
All of these were added to milk and then we had to wait one minute to give time for a reaction.

Tea and Milk
Brianna and Grace thought the colour would change. Three kids agreed with them.
Kyle thought bubbles would form. Four kids agreed with him.
Hannah thought they would mix togethe. Three kids agreed with her.
Sophie thought they would explode. Thirteen kids agreed with her.
Lilly thought the mixture would turn darker and two kids agreed with her.

What happened?
They did mix together. It looked like milky coffee.

Lemonade and Milk
Michael thought bubbles would form. Six kids agreed with him.
Desiree and Kyle thought it might explode. Twelve kids agreed with them.
Brianna thought nothing would happen and three kids agreed with her.
Mayana thought steam might rise and four kids agreed with her.

What happened?
The protein in the milk curdled because the lemonade changed the pH levels in the milk.

Orange Juice and Milk
Alicia thought they would mix together and four kids agreed with her.
Lilly thought the liquid would turn orangey brown.
Liam thought it would turn ice like. Eleven kids agreed with him.
Jade thought they would bubble and five kids agreed with her.
Karen thought the mixture would turn a lighter colour and four kids agreed with her.

What happened?
The protein in the milk curdled because the orange juice changed the pH levels in the milk.

The orange juice and lemonade had a similiar effect. The tea didn't make the milk curdle because it did not change the pH level of the milk.
