Science- Is the oldest child the tallest child?

Today in Science we were investigating if the oldest child in our class was the tallest child. 

First we made a prediction. Yes or no. 

This group of girls thought yes!

William and Alex volunteered to order the children from smallest to largest.

Do you think they did a good job?

We then used a measuring tape to see how tall we all were. 

We discovered that Helena was oldest child and the tallest child in our class. 

So in our class the oldest child was the tallest child!
