a. 5 qualitative observations: milk tea tastes sweet, the room is warm, the moon cake is square-shaped, my shoes are green, the cookies smell delicious
b. 5 quantitative observations: six books on the table, a dozen of chips on a table, 2 people in the room, the candy costs &2.5, room temperature is 68°F
2. Photosynthesis, car rusts, digestion, detergents, combustion, cooking, baking, respiration, forming water, pesticides

a. I always cry when I cut onions so I want to find a solution for it. I researched online and found some ways such as wash the knife before cutting onion, wear goggles, or cut onions under running water. I tried all these methods to test which one will work best and the results is to wear goggles will prevent fumes blow into your eyes.

Scientists use the same scientific method to follow steps (observation, hypothesis, and experiment) to have a better understand of the worlds; however, they make different hypothesis and approach the problem in their own ways to find solutions, therefore some of them have different results the order.
5. Concerns:
a. I’m worried I cant remember all of the reactants and products in Chemistry
b. Doing lab also counts as part of my grades and I didn’t do experiments a lot in lab lab before
6.
a. Photosynthesis: plant will convert sunlight into energy, release oxygen so humans can breathe, and store energy as sugar in its seeds.
b. Respiration – humans can exhale and inhale to maintain their lives
c. Plastic – material that plays an important part in everyday loves (bottles, technologies, plastic bag, toys) there are different types of plastic, it has various properties and some can be recycled.
7. Chemistry is a study of how materials, matters, and energy are created or transformed as well as their properties, appliances in everyday lives and at works.
a. Chemicals are the chemical substances that can combine together to form a new substance. Each chemical has its own characteristic and
