The Mad Scientist's Method
When a mad scientist makes an educated guess about what will happen in an experiment, this is what it is called.
What is a hypothesis?
Which macromolecule is the body's main quick source of energy?
Carbohydrates
Known as the “haunted powerhouse,” this organelle gives energy to keep monsters moving.
What is the mitochondria?
What type of biological molecule speeds up chemical reactions in living things?
Enzymes
What is the process by which plants use light energy to make sugars?
Photosynthesis
What is the movement of particles from an area of higher concentration to an area of lower concentration?
Diffusion
What is the process of maintaining relatively stable internal conditions?
Homeostasis
I pump all day, every day, without you having to think about it. Which organ am I?
The Heart
This is Mr. McAskill's first name. Spelling counts!
Who is Mata?
In a haunted lab, the bubbling potion is the variable you change on purpose. This variable is called the __________.
What is the independent variable?
Which macromolecule stores long-term energy and is a major component of cell membranes?
Lipids
The “crypt keeper” of the cell stores potions, water, and other creepy concoctions.
What is the vacuole?
What is the molecule that an enzyme binds to and acts upon called?
Substrate
In which organelle does photosynthesis occur?
Chloroplasts
What special type of diffusion involves the movement of water across a selectively permeable membrane?
Osmosis
When your body gets too hot, what happens to sweat production?
It increases to help cool the body through evaporation.
I protect the outside of a cell and decide what can enter and leave. What am I?
The Cell Membrane
Mr. McAskill did this for a profession before becoming a teacher.
What is a Real Estate Agent?
The ghosts in the experiment start glowing brighter as the potion gets hotter. The brightness is being measured. This variable is called the __________.
What is the dependent variable?
Which macromolecule is built from amino acids? .
Proteins
This “ghostly gatekeeper” controls what enters and leaves the spooky cell.
What is the cell membrane?
What is the region of an enzyme where its substrate binds called?
Active Site
What sugar is produced during photosynthesis and can be used in cellular respiration?
Glucose
A drop of food coloring spreads throughout a glass of water without stirring. How does this happen? Explain the movement
Diffusion - moves from high to low concentration
What is the name of the feedback in which a response counteracts a change to return a condition toward its normal range?
Negative Feedback
I help break down your food, but I am not a body system. I am a protein that speeds up chemical reactions. What am I?
An enzyme
Mr. McAskill has this many animals.
Besides all his students, what is 6?
1 snake, 2 fish, and 3 cats.
Dr. McAskillstein repeats his experiment three times to make sure his spooky results are real. This step is called the __________.
What is testing or repeating the experiment to verify results?
Which macromolecule stores genetic instructions and includes DNA and RNA?
Known as the “witch’s workbench,” this organelle produces proteins needed for all your experiments.
What are ribosomes?
Why might an enzyme stop working properly when exposed to extremely high temperatures?
Denatures and the active site changes shape.
What process releases usable energy from glucose, and in which organelle does most of it occur in eukaryotic cells?
An animal cell is placed in a solution with a higher solute concentration than its cytoplasm. What will generally happen to the cell?
Water moves out of the cell by osmosis, causing it to shrink.
When your blood glucose rises after a meal, which hormone helps lower it?
Insulin
I am a body system that includes your brain, spinal cord, and nerves. I help you react when you touch something hot. What am I?
A nervous system
Before teaching and real estate, Mr. McAskill went to school to learn about this branch of Science.
What is Marine Biology?
After brewing dozens of glowing potions, the mad scientist concludes that temperature affects glow intensity. This step is called the __________.
What is drawing a conclusion?
A food sample tests positive for starch. Which type of macromolecule is present AND what indicator is used to test for it?
The “green phantom” captures sunlight to make magical energy for plants and plant monsters.
What are chloroplast?
An enzyme works best at pH 7. Its activity drops sharply at pH 2. Explain why.
The highly acidic conditions can change the enzyme's shape and active site, reducing its ability to bind the substrate and catalyze the reaction.
A plant is placed in darkness for several days. Explain what happens to photosynthesis and why the plant can still use energy for a while.
Photosynthesis decreases dramatically without light, but cellular respiration can continue using stored sugars to release energy.
A plant cell is placed in pure water. Explain the direction of water movement and why the cell usually does not burst like an animal cell might.
Water enters the plant cell by osmosis. Its rigid cell wall resists expansion, creating turgor pressure and helping prevent bursting.
During exercise, your body temperature rises. Describe two responses that help return it toward its normal range.
Sweating increases heat loss through evaporation, and skin blood vessels dilate to increase heat transfer to the surroundings.
This organ is responsible for allowing you to breath and is the cause of hiccups. What am I?
What is the Diaphragm?
This is the longest amount of time that Mr. McAskill has held his breath for.
What is a 6 minutes?
