Grade 1 Science: 10 Free Practice Questions

Answer: Light from the Sun bounces off the Moon
The Moon shines because sunlight bounces off it. The Moon does not make its own light. The Sun's light travels to the Moon and bounces off its surface toward Earth. That reflected sunlight is what makes the Moon look bright to us. Students commonly believe the Moon makes its own light, but it only reflects light from the Sun.

Answer: Roots
Roots hold a plant in the soil and take in water. Roots grow down into the ground. They anchor the plant so it does not fall over, and they soak up water for the plant to use. Students often pick the leaf because leaves make food, but leaves do not take in water from the soil.

Answer: A stick of glue
A glue stick joins two pieces of paper together. To join means to hold two things so they stay together. Glue sticks to both papers and holds them. The other choices cannot hold paper together. Some students choose water because it makes paper wet, but water does not make paper stay joined.

Answer: A glass mirror
A glass mirror feels smooth. Texture is how something feels when you touch it. Sandpaper, a pinecone, and tree bark all feel rough and bumpy. A glass mirror feels flat and smooth with no bumps. Students may pick sandpaper because it looks flat, but its surface is covered in tiny rough grains.

Answer: a star
The Sun is a star.

Answer: The parent hears it and brings food
Chirping tells the parent the young bird is hungry, so the parent brings food. Young animals send signals to their parents. When the baby bird chirps loudly, the parent hears the sound and understands the chick needs food, then feeds it. This helps the chick get what it needs to live and grow. Students may think chirping grows feathers, but the sound is a signal for help, not a way to grow body parts.

Answer: Smell, using your nose
You use your sense of smell, using your nose, to smell a flower. Each sense uses a body part. To smell something, you use your nose. Ears are for hearing, eyes are for seeing, and feet are for standing and walking. Students may pick sight because we look at flowers, but seeing a flower does not tell you how it smells; only your nose can do that.

Answer: it melts
Warmth melts ice into water.

Answer: the Sun
The Sun shines in the daytime.

Answer: The moon changes its shape in the sky over time
The moon appears to change shape from night to night. As days pass, the lit part of the moon we see changes, so it can look like a full circle, a half, or a thin sliver. This is a repeating pattern in the sky. Students may think the moon breaks or melts, but it only looks like it changes shape; the moon itself is not breaking apart.
