Lesson Planning with Me!: Magic Mixture

Lesson Planning with Me

Hello! I teach an integrated preschool classroom, which means I am responsible for students ages three to five with special needs of all types as well as typical developing students. My students range in ability from a toddler to a typical kindergartener. Therefore, my activities must be able to reach a wide range and be easily adjusted for multiple ability levels.

I created this blog as a way to keep track of the fantastic ideas I have gathered over the years. Because I just randomly add activities to the blog, use the search, standard list, or theme list on the left side to find the activities you are after!

I also create and sell resources that can be found at TeachersPayTeachers and Teacher's Notebook.

Magic Mixture - Apple Dunking

From National Geographic:

Illustration: a boy looking at apple slices and a lemon.

YOU WILL NEED

An apple
Half of a lemon
Shallow bowl
Water
Knife (ask a parent for help)

HERE'S HOW
Peel and slice an apple. Cover one slice with water in a shallow bowl. Sprinkle a second slice with the juice of half a lemon. Leave another slice exposed to the air. Wait about an hour, then compare. The slice with nothing on it turns brown.

WHY?
When an apple is cut open, chemicals inside the apple combine with oxygen from the air to form a brown coating. The coating keeps oxygen from getting deeper into the apple. Water protects the first slice from oxygen in the air so it stays white. Vitamin C in the lemon juice binds with oxygen, keeping oxygen away from the second slice, so it stays white the longest.
