Research Project
Young scholars learn the characteristics of arachnids by researching the arachnid of their choice and producing a 4 to 5 paragraph research paper.
Curated OER
Speed and Collisions Administration Procedures
Young scholars investigate speed as an important variable regarding force of an impact. Students roll a car down a ramp and into a block of wood. The distance the car travels, the time until impact and the distance the block moves are...
Curated OER
Aerospace
Learners experiment with weight and balance of a glider. In this flight instructional activity students construct their own flying glider and record their experiment with it.
Curated OER
Biofilms Are Everywhere
Students research biofilms and create brochures. They role play as advertising firm members assigned to educate the general public about biofilms. They create "wanted dead or alive" posters about harmful and helpful biofilms respectively.
Curated OER
Microbes: Too Smart for Antibiotics?
Students examine how germs spread from one person or object to another. They discuss antibiotic resistant bacteris and examine the benefits of microorganisms. They explore methods of curbing antibiotic resistance.
Curated OER
The Cantankerous Pathogen
High schoolers explore what factors influence the spread of infectious diseases. They explain how human manipulation of the environment affects the transmission of diseases.
Curated OER
Will Biotech Crops Solve World Problems?
Pupils read an online article to examine what biotechnology and agricultural biotechnology are. They answer questions and complete worksheets based on the article's information.
Curated OER
Click, Clack, Moo: Electric Blanket Science
Students read Click, Clack, Moo: Cows That Type by Doreen Cronin and discuss the similarities and differences between electric blankets and regular blankets. They brainstorm a list of reasons why the farm animals wanted electric blankets.
Curated OER
Cell Swelling and Shrinking
Students examine the concept of osmosis in relation to dehydration. They identify the function and structure of semi-permable membranes. They predict how certain processes can affect the characteristics of an organism.
Curated OER
Swingers
Students investigate the motion of a swinging pendulum. They experiment with a pendulum to find out why it might swing at different speeds at different times.
Curated OER
Magnifiers
Students describe how several different objects magnify a provided sentence and decide if they are good magnifiers or not. They then write a sentence describing two properties an object must have in order to be a good magnifier.
Curated OER
Interdisciplinary Task: Weather
Students design a chart to use to record the weather for five days. They then build an anemometer to record wind speed and discover why they are used for this purpose.
