Pufferfish: A family of fish called Tetraodontidae known for puffing up. Some have short, prickly bumps that appear when they puff up.

Porcupinefish: A family of fish called Diodontidae. Like pufferfish, they also puff up. They have long spikes that are visible even when they are not puffed up, and that point out when they do puff up. 

Tetrodotoxin (TTX): A neurotoxin present in some pufferfish, porcupinefish, triggerfish, and ocean sunfish. A very dangerous toxin with no known antidote.

Pufferfish Spines: A special type of scale on pufferfish that lays flat until the fish puffs up, which causes the spines to spike out as a defense strategy.

In the future your children will ask you, ‘What do these stones mean?’ Then you can tell them, ‘They remind us that the Jordan River stopped flowing when the Ark of the LORD’s Covenant went across.’ These stones will stand as a memorial among the people of Israel forever.” Joshua 4:6-7 (NLT)

“In the future your children will ask you, ‘What do these rocks mean?’ Tell them, ‘Israel crossed the Jordan River on dry land. The Lord your God caused the water to stop flowing until you finished crossing it, just as the Lord did to the Red Sea. He stopped the water until we crossed it. The Lord did this so all people would know he has great power and so you would always respect the Lord your God.’” Joshua 4:21-24 (NLT)

Terms Learned in This Episode:

Rock: A solid object made from nature. Many are made from minerals.

Mineral: A natural substance made from nature, such as from the earth’s crust, but not made from living things. A mineral’s atoms (tiny building blocks) are arranged in repeating patterns, forming a crystal structure.

Metamorphic Rocks: Rocks changed from one form to another by extreme heat and/or pressure.

Rockhounding: An activity where people go out and search for and collect rocks, minerals, fossils, or gemstones from nature.

Pumice Stone: A lightweight igneous rock formed when lava rapidly cools. Pumice is porous, meaning it has small holes and can float.

Quartz Geode: A rock with a crystal cave inside. The crystals are made from a mineral called quartz. The quartz mineral builds up in the hollow inside of a rock to form beautiful crystals inside.

Agates: Formed in hollow cavities in rocks from a type of quartz. Minerals are laid down in layers, creating a magnificent striped pattern.

Scriptures Referenced in This Episode:

“Meanwhile, the disciples were in trouble far away from land, for a strong wind had risen, and they were fighting heavy waves. About three o’clock in the morning Jesus came toward them, walking on the water. When the disciples saw him walking on the water, they were terrified. In their fear, they cried out, ‘It’s a ghost!’

But Jesus spoke to them at once. ‘Don’t be afraid,’ he said. ‘Take courage. I am here!’” Matthew 14:24-27 (NLT)

“Peter said, ‘Lord, if it is really you, then command me to come to you on the water.’

Jesus said, ‘Come.’

And Peter left the boat and walked on the water to Jesus. But when Peter saw the wind and the waves, he became afraid and began to sink. He shouted, ‘Lord, save me!’

Immediately Jesus reached out his hand and caught Peter. Jesus said, ‘Your faith is small. Why did you doubt?’”  Matthew 14:28-31 (NLT)

Terms Learned in This Episode:

Hydrogen Bonding: Water’s ability to stick to itself. Water molecules are made from two hydrogen atoms with a slightly positive charge and one oxygen atom with a slightly negative charge. These positive and negative charges make a water molecule act like a magnet, sticking to other water molecules.

Water Surface Tension: An invisible shield on top of the water created by many, many water molecules sticking together through hydrogen bonding. This shield creates a tightly packed layer of water that resists external forces.

Microsetae: Hair-like structures covering a water strider’s legs that repel (push away) water.

Hydrophobic: Something that is hydrophobic presses away from water and does not mix well with it.

Scriptures Referenced in This Episode:

“Then the Lord God took dust from the ground and formed a man from it. He breathed the breath of life into the man’s nose, and the man became a living person.” Genesis 2:7 (NCV)

“The Spirit of God created me, and the breath of the Almighty gave me life.” Job 33:4 (NCV)

“Let everything that breathes praise the Lord...” Psalm 150:6 (NCV)

Terms Learned in This Episode:

Oxygen: A chemical element. It is very simple and cannot be broken down into more basic pieces. It is essential for life and gives us the energy we need to do everything we do.

Dissolved Oxygen: Oxygen that comes from the air and mixes into the water. This can happen at the water’s surface, where air mixes with water, and through plants in the water absorbing oxygen. This is the oxygen available to underwater creatures.

Gills: An organ in fish used to soak up oxygen from the water. Gills are full of blood vessels. When a fish scoops in water through its mouth, the water runs over the gills, and the blood vessels in the gills soak up oxygen from the water and carry it to the rest of the fish’s body.

Countercurrent Exchange System: A system God engineered into fish by which the blood in a fish’s gills flows in the opposite direction from the water flowing over the gills, allowing the fish’s blood to take in enough oxygen from the water.

Cutaneous Respiration: “Skin breathing.” This is when oxygen is absorbed (taken in) through the skin instead of through lungs or gills.

Diffusion: When a substance moves from an area of high concentration to an area of low concentration, like spreading.

Book Lungs: Thin, stacked, plate-like structures on the underside of a spider’s abdomen through which it gets oxygen. Air flows between the thin plates, and oxygen diffuses into the spider’s bloodstream.

Hemolymph: An equivalent to blood in spiders. Fluid that transports oxygen along with nutrients and other molecules through a spider’s body.
