Unit 1: Bath Bomb
Name the three states of matter and examples of each.
What is...
Liquid?
Solid?
Gas?
True or False:
You do not need H2O to heat up an MRE.
What is FALSE?
Name the five main parts of the digestive system in order.
What is...
Mouth
Esophagus
Stomach
Small Intestine
Large Intestine?
This is the structure that absorbs glucose into the bloodstream in the small intestine.
What are villi?
This is the gas coming from the bath bomb.
What is CO2?
These were the reactants of our homemade flameless heater.
What is aluminum, copper sulfate and saltwater?
This molecule gets absorbed into the bloodstream in the small intestine.
What is glucose?
This is when reactants rearrange to make products, resulting in something new that wasn't there before.
What is a Chemical Reaction?
This was our unit's driving question.
What is..."How can we make something new that wasn't there before?"
This type of reaction feels warm, as energy is exiting the reaction system. Energy transfers from the reaction to the surroundings.
What is Exothermic?
These are the three ways fat can be used in the body.
Current Energy?
Fat Stores for Later?
Growth?
This is when one quality directly affects another, and you can't do both.
(ex. more material means it will be more expensive)
What is Trade-off?
Lots of this molecule is needed in order to activate the bath bomb reaction.
What is H2O?
This type of reaction feels cold, as energy is entering the reaction system. Energy transfers from the surroundings to the reaction.
What is endothermic?
These are the reactants and products of cellular respiration.
What are...
Reactants: Glucose + Oxygen
Products: CO2 and H2O
This is the work we do to make our solution the best it can be, design-wise.
What is optimize?
These were the two powders inside the bath bomb that take place in the reaction.
What are baking soda and citric acid?
This was our unit's driving question.
What is..."How can we use chemical reactions to solve problems?"
This was our unit's driving question.
What is..."What's happening in our bodies to make us feel the way we do?"
These are the tiny sacs of air that allow oxygen to move into the bloodstream from the lungs.
What are alveoli?
