Passage 3 • Earth Science How Thunderstorms Form
[1] Thunderstorms are powerful weather events that form when warm, moist air rises quickly into the sky. [2] As the warm air travels upward, it cools down and condenses into towering cumulus clouds. [3] Inside the growing cloud, tiny droplets of water freeze into ice crystals and churn against each other. [4] Many children like to splash in shallow puddles on the sidewalk after a light rain shower. [5] This swirling friction creates strong electrical charges that produce bright flashes of lightning. [6] When the heavy clouds can no longer hold the water, pouring rain and booming thunder crash down to Earth.

Passage 4 • Ocean Life The Remarkable Octopus
[1] The octopus is a clever sea animal that uses incredible defense tricks to escape dangerous predators. [2] Special color-changing cells in its skin allow the octopus to blend invisibly into nearby rocks and coral. [3] If a hungry shark comes close, the octopus squirts a thick cloud of dark ink to blind the attacker. [4] Seafood restaurants serve cooked calamari rings with lemon wedges and dipping sauce.

Passage 5 • Clean Energy Power from the Sun
[1] Solar panels are fascinating inventions that turn clean sunlight directly into usable electricity. [2] Each solar panel contains many small dark squares called photovoltaic cells made of silicon. [3] When particles of sunlight called photons hit the silicon cells, they knock electrons free. [4] Many people wear dark sunglasses and sunhats to protect their eyes at the beach. [5] The flow of these freed electrons creates an electric current that travels through metal wires. [6] An inverter then converts this current so it can safely power lights, computers, and refrigerators in homes.
