Read the passage.
Volcanoes form when molten rock, called magma, rises from deep inside Earth and erupts at the surface. Beneath the ground, intense heat and pressure melt rock into magma. When pressure builds up, magma forces its way through cracks in Earth's crust. Once magma reaches the surface, it's called lava. Lava flows down the volcano's sides, destroying everything in its path. As lava cools and hardens, it forms new rock, gradually building up the volcano's cone shape.
According to the text, what is magma called after it reaches the surface?
Lava
Ash
Erosion
Crust

This question tests reading and comprehending informational texts at grade level (CCSS.RI.3.10: By the end of year, read and comprehend informational texts, including history/social studies, science, and technical texts, at the high end of grades 2-3 text complexity band independently and proficiently). Students must understand content-area text with moderate complexity. Grade 3 students should read and understand informational texts with: some challenging vocabulary (academic and domain-specific words), moderate sentence complexity (12-18 word sentences, mix of simple and complex), abstract concepts explained with examples, clear organization with main ideas and details. This passage is at the high end of grade 2-3 complexity (Lexile 640-780), meaning it challenges students appropriately while remaining accessible. Students demonstrate comprehension by identifying main ideas, understanding vocabulary in context, following cause/effect relationships, and explaining processes or concepts. This passage is about how volcanoes form. It explains magma rising and erupting with details including heat melting rock, lava flowing, and cone building. The passage uses academic vocabulary like magma, lava, and crust and includes process description with cause/effect. The complexity comes from scientific vocabulary, sentence structure, and abstract concepts of underground processes. Choice C is correct because it shows understanding of vocabulary and detail recall. The passage explicitly states that once magma reaches the surface, it's called lava. Choice A is incorrect because it confuses terms - crust is the outer layer, not what magma becomes on the surface. This error shows difficulty with domain-specific vocabulary in context. To help students: Build background knowledge before reading complex texts - preview key vocabulary, discuss topic, activate prior knowledge. Teach comprehension strategies: preview headings/structure, identify main idea and details, use context clues for vocabulary, visualize processes, ask questions while reading. For academic vocabulary, teach students to: look for context clues (definitions, examples, descriptions), break words into parts (photo-voltaic, meta-morphosis), use glossaries or word walls. Model close reading with think-alouds: 'This paragraph is mostly about [topic]. The author uses the word [vocabulary] - let me see if there are clues to its meaning. The next sentence says [context clue], so I think it means [definition].' Practice with varied informational texts (science, social studies, technical) at appropriate complexity. Gradually release responsibility: teacher models → guided practice → paired reading → independent reading. Use graphic organizers to track main ideas, vocabulary, cause/effect, sequences. Teach students to reread challenging sections, slow down for complex sentences, and monitor their understanding ('Does this make sense?'). Build stamina for longer, more complex texts. Watch for: Students who struggle with academic vocabulary, can't follow complex sentences, miss main ideas, don't use context clues, or give up on challenging texts. Provide scaffolding (vocabulary preview, graphic organizers, partner reading) while building toward independence.

Metamorphosis is the remarkable transformation some animals undergo during their life cycle. Butterflies experience complete metamorphosis, changing form as they develop. The process begins when a female butterfly lays eggs on a plant. A caterpillar, or larva, hatches and spends weeks eating leaves and growing larger. When fully grown, the caterpillar forms a protective shell called a chrysalis. Inside, its body reorganizes, and about two weeks later an adult butterfly emerges.
According to the text, what happens right after the eggs are laid?
The caterpillar forms a chrysalis around its body.
A caterpillar hatches and starts eating and growing.
The butterfly’s body reorganizes inside a shell.
The adult butterfly emerges and begins to reproduce.

Read the passage.
Camouflage helps animals survive by allowing them to blend into their environment. The Arctic fox has white fur in winter that matches the snow, making it hard for predators and prey to see. When spring arrives, the fox’s coat changes to brown, matching rocky ground where snow has melted. The walking stick insect looks like a twig, with brown coloring and a bumpy texture. Predators searching for food may walk right past it without noticing. These adaptations protect animals from danger and can also help them hunt.
What is the main idea of this passage?
Walking stick insects are the longest insects in the world.
Camouflage is an adaptation that helps animals survive.
Some animals live only in cold places with snow.
Predators always find their prey by using their sense of smell.

The ancient Maya civilization thrived in Central America for thousands of years. Skilled architects and engineers, the Maya built stone pyramids and temples without modern machines. They developed a writing system using hieroglyphs, symbols that stood for words and sounds. Maya astronomers carefully tracked planets and stars to make precise calendars. Farmers grew corn, beans, and squash using irrigation systems that moved water to crops. Although the classical Maya civilization declined around 900 AD, descendants still live in the region today.
Which detail supports the idea that the Maya were advanced thinkers?
Their civilization declined around 900 AD.
Descendants still live in Mexico and Guatemala today.

Read the passage.
Solar panels convert sunlight into electricity that powers homes and businesses. Each panel contains special photovoltaic cells made from silicon, which can capture light energy. When sunlight hits these cells, it knocks electrons loose from atoms, and the moving electrons create an electric current. This current flows through wires to an inverter, which changes it into the kind of electricity buildings use. Panels work best when positioned to receive maximum sunlight. Many people install them to lower bills and decrease pollution.
According to the text, why do people install solar panels on rooftops?
To make the roof heavier during strong winds
To lower electricity bills and reduce pollution
To turn electricity into sunlight during the night
To stop all clouds from blocking the sun

Read the passage.
The Grand Canyon is a spectacular natural wonder in Arizona. It stretches 277 miles and reaches depths of more than a mile. The Colorado River carved the canyon over millions of years through erosion. Water, wind, and ice slowly wore away layers of rock, leaving distinctive colorful walls. Geologists study the canyon because they can see rock layers that are nearly two billion years old. Those layers show different time periods in Earth’s history.
The passage explains that erosion shaped the canyon. What example does it give?
A huge earthquake split the land open in one day.
Water, wind, and ice slowly wore away layers of rock.
Volcanoes poured lava into the canyon to make cliffs.
People dug the canyon to create a national park.

Read the passage.
Volcanoes form when molten rock, called magma, rises from deep inside Earth and erupts at the surface. Beneath the ground, heat and pressure melt rock into magma. When pressure builds up, magma forces its way through cracks in Earth’s crust. Once magma reaches the surface, it is called lava, and it may flow down the volcano’s sides. As lava cools and hardens, it forms new rock that can build up the volcano’s cone shape. Some eruptions are explosive, sending ash into the atmosphere.
Why does magma move through cracks in Earth’s crust?
Rainwater soaks in and pulls magma to the surface.
Wind blows magma through cracks like dust.
Magma cools into rock and then melts again quickly.
Pressure builds up and pushes magma upward.
