Which of the following is NOT a scientifically proven benefit of eating dinner as a family?
Correct Answer
A. Closer relationships of family members
Explanation
Eating dinner as a family has been scientifically proven to have several benefits, such as higher grade point averages, improved self-esteem, and increased vocabulary. However, the given answer "Closer relationships of family members" is not a scientifically proven benefit of eating dinner as a family. While it is commonly believed that eating together can strengthen family bonds, there may not be sufficient scientific evidence to prove this specific outcome.
2.
Condensation is a result of the Sweaty Drink experiment.
Correct Answer
A. True
Explanation
The statement is true because condensation is indeed a result of the Sweaty Drink experiment. In this experiment, when a cold drink is placed in a warm environment, water droplets form on the outside of the glass. This is due to the temperature difference between the cold drink and the surrounding air. The warm air comes into contact with the cold glass, causing the water vapor in the air to condense into liquid form, resulting in the formation of water droplets on the glass.
3.
Which of the following is the correct outcome of the Salt on the Ice Cubes experiment?
Correct Answer
C. The ice cube with salt melts quicker
Explanation
When salt is added to ice cubes, it lowers the freezing point of water. This causes the ice to melt more quickly, as the salt disrupts the ice crystals and prevents them from forming. Therefore, the correct outcome of the Salt on the Ice Cubes experiment is that the ice cube with salt melts quicker.
4.
You will be able to drink the water in the Straw and Air Pressure experiment.
Correct Answer
B. False
Explanation
In the Straw and Air Pressure experiment, the water is sealed inside the straw by placing a finger over the top end. When the finger is released, the air pressure pushes the water out of the straw. Therefore, it is not possible to drink the water in this experiment as it is expelled due to the air pressure.
5.
Which of the following is NOT a suggested idea of how to talk about science at the dinner table?
Correct Answer
C. Ask your student to name all the elements in the periodic table
Explanation
Asking your student to name all the elements in the periodic table may not be a suggested idea for talking about science at the dinner table because it can be overwhelming and may not lead to a meaningful or engaging conversation. It is important to create a comfortable and enjoyable environment for discussing science, and asking such a specific and extensive question may discourage participation or make the conversation feel like a test or quiz.
6.
A shark is fish.
Correct Answer
A. True
Explanation
A shark is classified as a fish because it possesses the characteristics and features that define a fish. Sharks have gills, a streamlined body, and fins, which are all typical traits of fish. Additionally, sharks live in water and rely on swimming to move and hunt for food, further confirming their classification as fish.
7.
What are MOST humans are considered which of the following?
Correct Answer
C. Omnivores
Explanation
Most humans are considered omnivores because they have the ability to consume and digest both plant-based foods and animal-based foods. This is evident in the human diet, which typically includes a variety of fruits, vegetables, grains, as well as meat, fish, and dairy products. Our teeth, digestive system, and nutritional needs are adapted to consume and derive nutrients from both plant and animal sources, making us omnivorous beings.
8.
The process plants use to get food and energy is called photosynethsis.
Correct Answer
A. True
Explanation
Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to produce glucose (food) and oxygen. This process occurs in the chloroplasts of plant cells and is essential for the plant's growth and survival. Therefore, the statement that the process plants use to get food and energy is called photosynthesis is true.
9.
Science talk at the dinner table can include:
Correct Answer
D. All of the above
Explanation
Science talk at the dinner table can include a wide range of topics such as animals, experiments, and trivia. This means that all of the given options are correct. Discussing topics about animals can involve learning about their behavior, habitats, or even conservation efforts. Experiments can be shared and discussed to spark curiosity and understanding of scientific concepts. Trivia can be a fun way to engage in scientific discussions and share interesting facts. Therefore, all of these options are suitable for science talk at the dinner table.
10.
Science at the dinner table requires a lot of time and energy.
Correct Answer
B. False
Explanation
This statement is false because science at the dinner table does not require a lot of time and energy. It may require some level of curiosity and interest, but it does not necessarily require a significant amount of time or physical exertion. Science discussions at the dinner table can be casual and informative, allowing for engaging conversations without being overly time-consuming or exhausting.
