Grade 1 Science Practice Test: Plants, Animals, Light and Sound

Sounds are made when something vibrates, which means it shakes back and forth very fast. Touch your throat when you talk and you can feel it shake.

Roots grow down into the soil and take in water. The water then moves up the stem to the rest of the plant.

We see things only when light shines on them and comes to our eyes. With no light at all, you cannot see anything, not even shiny or white things.

Clear glass lets light pass through, so you can see outside. Wood, metal and cardboard block the light.

A shadow is the dark shape behind an object that blocks light. Light going through clear glass does not make a dark shadow.

Young animals look a lot like their parents. A puppy has fur and four legs, just like a grown dog. Dogs do not hatch from eggs.

Baby birds cannot find food yet, so their parents feed them. This helps the chicks grow and stay alive.

A turtle can pull its head and legs into its hard shell to hide from animals that want to eat it. The shell protects it.

Plants need light to grow well. Without light, a plant turns pale (light yellow) and weak.

A fire alarm beeps to tell people to get out. A stop sign, a flashlight and a note send messages you see, not hear.
