Using numbers and units of measurements as part of your data makes your experiment more accurate and precise. Using observations based on your types of senses add more credibility to your result. Which step of the scientific method helps you identify different types of observation that you needed to accomplish to be able to guide you with creating a scientific prediction?
Scientific Observations
Qualitative Observations Only
Quantitative Observations Only
Both Qualitative and Quantitative Observations
HOT (High Order Thinking) questions help us think, apply and synthesize (combine) concepts. Which question is an HOT?
What are the different ingredients of Spam Musubi?
Which ingredients of Spam Musubi are considered healthy?
If you are to make Spam Musubi healthier, what would you add/change/replace?
How will you teach someone (who has never had it) how to make Spam Musubi?
A group of students at Wai'anae High School wanted to find out how many days they can eat tomato soup until they get sick. Identify the most effective control group to do this experiment.
A group of students not consuming soup
A person consuming soup for only 2 days
A group of scientists identifying the ingredients of soup
You are interested in finding out how stress on studying for the finals affects heart rate of students at Wai’anae High School. Identify the most effective independent variable to do this experiment.
Heart rate (pulse) when studying for finals
Amount of Stress (e.g. drama, relationships)
Different sources of related stress (e.g. home, peers)
Amount of studying the students do to prepare for finals
A Neuroscientist (studies the brain) studies the impact of a certain drug on brain cancer cells. Identify a possible independent variable to do this study.
Timing of taking the drug
Dosage of drug to be taken
Impact of drug on cancer cells
Number of scientists studying the drug
Stroop Effect Activity demonstrates the reaction time of a task and is often used to illustrate the nature of automatic processing versus conscious visual control (what you see and what you know). In our class, we used mismatched words and colors. Based on our class performances of the activity, which statement(s) is 100% true about Stroop effect?
All students knew the different colors by heart.
All students were able to read/recognize the colors.
All students are always on task with all Stroop Activities.
There is a mixed reaction and result with our performance of Stroop Activities.

Just enough space between particle to slide around
States of Matter (solid, liquid, gas and plasma) differ from how the molecules (building blocks of matter) are arranged. How would you describe the molecular structure of GAS?
Compact and tightly packed, vibrating

How does your bottle rocket relate to Newton’s 2nd Law of Motion?
(1) If you leave the rocket long enough on the launcher, it will fly on its own.
(2) The rocket will not launch until the compressed air and water are released.
(3) The bike pump adds pressure to the bottle.
(4) The rocket and launcher have an equal forces on each other.
