The process of understanding how the natural world works through observation and experimentation.
What is science?
Convert 34daL to deciliters
3400dL
Students write an explanation about why a light source is needed for a person to see an object. Students use the evidence they found during their investigation and from other research to explain why this occurs.
Constructing explanations
Test subjects sprayed one arm with a new mosquito repellant brand and the other arm with the leading brand. After 4 hours, they checked their arms for the number of bites. What is the dependent variable?
The number of bites
What do we measure when we use grams as our base unit?
mass
How do we as humans use technology and engineering?
In our everyday lives (housing, health, education)
To explore things we are curious about
To help us improve the future
Convert 86.5 km to meters
86500m
Students create a model of a water molecule out of marshmallows and toothpicks to better understand the physical structure of the molecule and how the atoms bond to each other.
Developing and using models
Students want to see what type of liquid flowers would grow best in. They use tap water, vinegar, milk, and grape soda. They then measure how tall the plants grow after 5 weeks. What is the independent variable?
Type of liquid
7 units3
A fact or event that can be observed with the 5 senses.
What is a phenomenon?
Convert 480cm to meters
4.8m
How does the size of a magnet affect the amount of paper clips it can pick up?
Asking questions and defining problems
What variable is being intentionally changed by the scientists in the experiment?
Independent or dependent?
Independent variable
What do we measure when we use liters as our base unit?
volume
The process of asking questions to better understand something.
What is inquiry?
Which is greater? 560m or 15hm?
15hm
Students analyze a table of data that has the amount of chirps that crickets make during warm summer nights. They now want to determine how many chirps they will make when the it is 30oC and 35oC .
Using mathematics and computational thinking
30 overweight dogs are given a new dog food to see if they will lose weight. 30 dogs are given their normal dog food. Their weight is measured after 8 weeks. Which group is the control group?
The 30 dogs given their normal dog food
What units do we use to measure the volume of a 3D object?
units3
A representation of a process, system, or events; using drawings, diagrams, and pictures.
What is a model?
Which is greater? 20mm or 0.2cm?
20mm
Students engage in a debate about the survival rate of a hypothetical animal with certain anatomical features
Engaging in an argument from evidence
Define the control group and explain why it is important.
The group that did not receive treatment of that is not being tested on. It is important so you can have something to compare the experimental group to.
When we measure the volume of water in a graduated cylinder, what is the curve that we read called?
Meniscus
