Apple Science Investigation

This post contains affiliate links

As part of our apple unit, we explored different types of apples to see how they were the same and how they were different- inside and out.  Read on for the details of our investigation!

Each of the boys got a little investigation book to record their findings. Inside the book, they are asked to observe the outside of their apple, make predictions, and compare/contrast their apples to other types of apples.   

Types of apples
First, they each chose an apple to investigate and explored the outward properties.  They recorded the variety (Granny Smith, Red Delicious, Gala) and the color(s) of the apple they chose.

Measuring apples
The boys measured the length and width of their apples and recorded it in their science investigation books.

Making Predictions

In their books, they answered some questions and made some drawings to predict what the inside of their apples would look like.  They also predicted how their apple would compare to an apple of a different variety.

Sink or float?
We put our apples in a bowl of water to find out if they sink or float.  At first we didn't have enough water in the bowl and the didn't float, so we added more.  Then, sure enough, they floated!  That gave us an opportunity to learn that if the volume of the water weighs less than the object inside, the object will sink.  But if the object weighs less than the amount of water it's in, it will float!

We couldn't let a bowl of floating apples go without bobbing for apples!  They had so much fun.

Corinne especially loved splashing in the water!

Star shaped seed pods and seeds

The boys ate their apples whole, but we cored Corinne's Granny Smith and cut it in half to see the "star" and seeds a little better.  The cut cores made such perfect stamps, we used them to make star prints-- a really fun way to learn about the star shaped seed pods inside every apple!  I thought it would be fun for the kids to make the prints on the covers of their investigation books, but they preferred to draw on their covers instead. :)

Do seeds from different apples look different?
It turns out that the seeds of some apples look a little different from each other in some cases.    It was the most noticeable between the Granny Smith and the Gala apples, mostly in the color.  The boys recorded their seed findings in their books.

The kids also did a taste test to explore how different types of apples taste different.  We also talked about how different types of apples are a better fit for different recipes.

The kids had tasted Gala and Red Delicious in the past, but this was their first time tasting a raw Granny Smith.  Corinne was the only one who liked it- she ate the whole thing by herself!  The boys were surprised that the sour tasting apples could taste so good in apple pie!

I made ours into little books by sliding them into  report covers, and it worked out really well.  (fyi, I found a 50 pack of report covers for under $20, I think that's a pretty good deal if you use them often.  Personally, I like to use them to store collections of kids' craft projects).

  1. Ooooo. I like this. What a great idea to compare different types of apples. I love that you measured them and tested to see if they float or sink. Here's an apple investigation activity we did - rotting apples - http://highhillhomeschool.blogspot.com/2012/05/rotting-apples.html - Each Friday I host an entertaining and educational blog hop. Please stop by and link up.


  2. Tanya - Thanks so much for sharing. There are some GREAT ideas in here and as always you have such gorgeous pictures {and kids!}. :)
