Lakes and Ponds (Week 7)

manna moment

John 6:19-”When they had rowed about three or four miles, they saw Jesus walking on the sea and coming near the boat, and they were frightened.”  Seeing as all things, including the seas, were made through Jesus, (John1:3)  I am not surprised that he could walk on water, however this would be considered a supernatural feat.  It is not a supernatural feat for insects like water striders who walk on pond and lake water all the time.  The combination of the molecular structure of water when up against air plus the special design of the water strider’s legs make this feat possible in nature.  Mankind uses creation, water striders walking on water, to inspire innovation and scientists and engineers are working on a way for man to walk on water.  And even if they come up with a way to do this, it was Jesus who did it first supernaturally.

Pond Food Chain

Using some Dyno Cards, the students were able to put a food chain together.  This will be helpful to them on their Lakes and Ponds Ecosystem Sheet.

lakes and Ponds Note Taking Sheet

I didn't necessarily have a focused book on Lakes and Ponds and so I gleaned some great information from God's Design Properties of Ecosystems. Along with Dr. Fleming's amazing illustrations, this note taking guide came together.  There are key words in each box that are grayed out that the students can trace over them while we discuss the topics in the guide

Penny Surface Tension Investigation

The only materials that you will need for this investigation are:

• Penny
• Water
• Pipette/eye dropper/straw
• Small paper cup
• Paper towel

I really enjoyed doing this investigation.  Second and Third graders are perfect for this.  Each had to make a hypothesis of how many drops they could accumulate on their penny.  They, then, had to do three trials, add them up and divide to find the average.  The dividing was difficult and we had a math lesson within the science lesson.  Why not?  They go so well together.

This investigation emphasizes doing more than one trial and using the scientific method.

Documenting the data is very important.

Read Aloud:  From Tadpole to frog by wendy Pfeffer

Our fauna highlight today was the frog.  I picked the frog to contrast with the spadefoot toad that we learned about earlier in the desert.  While reading, we compared the life cycles of the frog with the spadefoot toad.

Frog Life Cycle Bracelets

After we finished our read aloud, I gave each student a frog life cycle bracelet to color.  Once they were done coloring, we taped them on their wrists.  The students loved them and can remember the frog life cycle.
You can grab these for free on our TPT page.  If you click on the image, it should take you to our TPT store.
