Mrs. Timmons asked her class to share their ideas about what causes the different
phases of the Moon. This is what some of her students said:
Mona: The Moon lights up in different parts at different times of the month.
Jared: The phases of the Moon change according to the season of the year.
Sofia: Parts of the Moon reflect light depending on the position of the Earth in rela-
tion to the Sun and Moon.
Drew: The Earth casts a shadow that causes a monthly pattern in how much of the
Moon we can see from Earth.
Trey: Different planets cast a shadow on the Moon as they revolve around the Sun.
Oofra: The shadow of the Sun blocks part of the Moon each night causing a pattern
of different Moon phases.
Natasha: The clouds cover the parts of the Moon that we can't see.
Raj: The Moon grows a little bit bigger each day until it is full and then it gets smaller
again. It repeats this cycle every month.
Which student do you agree with and why? Explain your thinking

Drew

Explanation:

Mona is wrong entirely but she doesn't have a good scientific reason for her answer

Jared is wrong because the different phases of the moon can be seen regardless of the season

Sofia almost had it but Drew has better reasoning

Trey none of the other planets can cast a shadow on Earth's moon

oofra the sun gives off light, it never casts a shadow

Natasha the clouds can obstruct ones view of the moon but that's doesn't change the phase of the moon on a global scale

raj the moon doesn't change sizes. ever

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.
