Christian World View

I intentionally weave biblical truths throughout our science units. The following are examples of how scripture was incorporated into the third grade Earth sciences unit.

24 “Therefore everyone who hears these words of mine and puts them into practice is like a wise man who built his house on the rock. 25 The rain came down, the streams rose, and the winds blew and beat against that house; yet it did not fall, because it had its foundation on the rock. 26 But everyone who hears these words of mine and does not put them into practice is like a foolish man who built his house on sand. 27 The rain came down, the streams rose, and the winds blew and beat against that house, and it fell with a great crash.”   Matthew 7

Why would a wise man want to build his house upon rocks? How is learning God’s word like building your house upon a rock? How does it protect you when storms occur (hard times)?

The Lord is my rock and my fortress and my deliverer; my God, my strength, in whom I will trust; my buckler, and the horn of my salvation, and my high tower. Psalm 18

Using your knowledge of rocks, why would God be called our rock?

I used geodes to explain how God cares less about our outward appearance and more about our heart (the desire to live a life pleasing to God). Geodes start as a hollow bubble inside a layer of rock. Over time, dissolved minerals seep into the hollow area.  As the mineral-rich water moves on through the bubble, tiny crystals are left behind. Although the outside of the geode is plain, the inside is beautiful!  What a perfect tool to teach this message.

But the LORD said to Samuel, “Do not consider his appearance or his height, for I have rejected him. The LORD does not look at the things people look at. People look at the outward appearance, but the LORD looks at the heart.”  1Samuel 16:7

New Books

I offer the fourth graders the opportunity to purchase Scholastic Books throughout the year. I use the bonus points from their orders to select books for the Science Lab and for classroom libraries. This month, I chose the books below and a magnetic fishing game for our PreK program. If your classroom doesn’t order Scholastic books and you would like to have that opportunity too, please let me know and I will send an order form home with your child.

Weather- Air Pressure

Weather labs are action packed!

Click here to watch us defy gravity. Water travels down the string because of cohesion and adhesion.

In the pictures below we are exploring what happens when you open a water bottle with a hole in its side. The water comes out of the hole like a fountain when you take off the top, but when you put the top back on, the water stops. Why?

We flipped a jar filled with water over with a card on top. Click here to see what happens. Then when we slowly slid the card away on another jar, the water didn’t come out. Click here to watch this step. Why?


Why does the candle go out when a jar is placed over it?


How does the candle magically relight?


This is called the magical refilling bottle. It appeared to be empty, but each time I turned it over, more water came out. How?

Lake Lanier Aquatic Study Program

What an informative and practical field trip! My students saw how Earth, chemistry, and biology sciences are interrelated.

A Description of our program from the Elachee Nature Science Center Site:

“Students climb aboard the floating classroom, Chota Princess II, for a hands-on exploration of the history, ecology and challenges facing Lake Sidney Lanier, Georgia’s most important reservoir. Students will sample plankton, collect lake sediments, measure turbidity (amount of cloudiness in water) and determine pH and dissolved oxygen levels. On shore, Elachee instructors engage students in complementary watershed activities including topographical map studies, storm water runoff demonstrations and water treatment plant simulations.”
