Third Grade Science Review

Jalissiah left a water bottle out in the Sun all day. When it was time to bring the bottle inside, it was too hot to pick up. Jalissiah left the bottle out overnight. What did Jalissiah observe about the water bottle the next morning before the Sun rose?

• The water bottle was still just as hot from the Sun the day before.

Harmony was working in the school garden and noticed that one of the plants had a broken stem. What will happen to the plant because the stem has broken?

• The plant will not be able to reproduce without its stem.

• The plant will not be able to produce its own food without its stem.

• The plant will not be able to transport nutrients without its stem.

• The plant will not be able to hold itself in the ground without its stem.

Juni and Rachel were observing the night sky and recording their observations with drawing. If Juni and Rachel observed the same part of the sky, what might be a reason why Rachel and Juni observe different amounts of stars?

• Rachel was using a telescope to make the observations which made more stars visible.

• Rachel was using a telescope to make the observations which made less stars visible.

• Juni was using a telescope to make the observations which made more stars visible.

• Juni was using a telescope to make the observations which made less stars visible.

Violet had a new toy that runs on solar power. Before using the toy, it must sit outside in the Sun for the batteries to charge. What properties of the Sun help it to charge the batteries?

• The Sun provides the toy with energy in the form of electricity and motion.

• The Sun provides the toy with energy in the form of electricity and light.

• The Sun provides the toy with energy in the form of light and heat.

• The Sun provides the toy with energy in the form of heat and motion.

Of the five stars observed, Hydri appears to be the least brightest star in the sky. However, Hydri emits more light than Centauri A and the Sun. Why does Hydri appear less bright even though it emits more light?

• Hydri is closer to the Earth, so it appears brighter in the sky.

• Hydri is closer to Earth, so it gives off more light to the places closer to it.

• Hydri is farther from the Earth, so it appears less bright in the sky.

• Hydri is farther from the Earth, so it appears brighter in the sky.

To answer this question, refer to the 'Observing the Stars' passage and chart. The scientists at MOSI started observing and recording the star data after one of them wondered why all the stars in the sky don't look the same. Which of the statements explains why scientists use observations to support answering questions?

• The observations are evidence that support an answer to the scientists' question.

• The observations are what the scientist thinks.

• The observations would change depending on who made them.

• The observations are what the scientists see.

Kaelan and Kerrie were walking home from soccer practice and making observations about the stars. Kerrie noticed a star that looked much brighter than the two stars next to it and told Kaelan that it was the biggest star in the sky. Kaelan said they couldn’t know for sure if the star was bigger than the other stars. What other statement explains why the star might have looked brighter than the stars around it?

• A. The brighter star could be farther away than the other stars.

• B. The brighter star could be closer than the other stars.

• C. The brighter star could be smaller than the other stars.

• D. The brighter star could be older than the other stars.

When students were leaving the lunchroom, they noticed a sign posted outside the bathroom door. What can the students infer based on this sign?

• The wet floor could cause someone to slip and fall.

• The wet floor could cause someone’s shirt to get wet.

• People should not be able to use the lunchroom when the floor is wet.

• The floor of the cafeteria will be covered in crumbs.

Caleb built a solar oven on a sunny day and used the oven to make s’mores. The next day was a cloudy day, and when Caleb tried to make s’mores again, the chocolate in the s’mores never melted. Which statement explains why the solar oven did not heat the chocolate on the cloudy day?

• There was not as much energy from the Sun to light up the solar oven.

• There was not as much energy from the Sun to heat the solar oven.

• There was more energy from the Sun to light up the solar oven.

• There was more energy from the Sun to heat the solar oven.
