  Cycle 3 Week 2 lesson: Water Lenses

Water is and amazing substance, and can do all kinds of things. In this pair of activities, you’ll make two simple magnifying lenses from water, and learn why water can do this. Then you’ll learn how two parts of our eyes, the cornea and the lens, help you see both near and far!


  Cycle 3 Week 3 lesson: Fingerprints

God makes each of us different, that’s for sure! From the color of our skin, hair, and eyes to the shapes of our face and the size of our bodies. But look closer and you’ll find that even in the little details, we are each unique creations.


  Cycle 3 Week 4 lesson: Every Breath You Take

Your lungs are part of the respiratory system, and they can do some amazing things. In this experiment you’ll measure your lung capacity, which is how much air your lungs can move in a single breath.


  Cycle 3 Week 5 lesson: Scritchy Scratchy

In the first experiment, you’ll learn how God made your skin to protect your body from damage. And to do that, He came up with a fascinating design that always makes more skin cells to replace the ones that are lost or damaged. In the second experiment, you’ll discover that you’ve got a well-designed sense of hearing. It’s directional!
