Sports Helmets and Impact Testing of Polymers
Learners examine the importance of good quality safety gear. In this investigative activity, students will tests various polymers, collect data, and analyze the data to determine which polymer is best for safety helmets. They will design...
Curated OER
Viewing Bateria
Students use microscopes to observe E. coli bacateria on prepared slides and in a live culture. They use micro-slide viewers to observe the shapes of various bacteria and the structures within the bacterial cell. Students make an...
Curated OER
Toboggan Science
Students conduct toboggan time trials to investigate the variables that have the greatest effect on toboggan speed. In small groups, they develop a hypothesis to test and perform three trials on the toboggan run for each variable.
Curated OER
Watching Crystals Grow
Students observe crystal growth of Epsom salts and the variables that hinder or help their nucleation and growth. They illustrate a series of drawings/pictures as the crystals grow. They look for the different shapes they form as well...
Curated OER
Survival Of The Fittest
Seventh graders examine the concept of an ecosystem and how there is a variety of representations of life that exist there. They look at the equilibrium that is reached in stable communities and how the variable of change in...

Rearranging Algebraic Equations
For this density worksheet, learners review how to rearrange the equation for density to solve for mass or volume. Then students complete 4 problems.
Curated OER
Viewing Bacteria
Young scholars investigate the characteristics harmful and helpful bacteria and observe structures within the bacterial cells. They use micro-slide viewers to observe the shapes of various bacteria and the structures within the bacterial...

Combined Gas Law
Students learn the combined gas law, undersand how it incorporates all of the different relationships that they have already learned, and manipulate it to solve numberical problems.
Curated OER
Distance over Time
Young scholars analyze velocity and how it is determined. They experiment with velocity in order to measure and calculate the magnitude of speed. They use examples in their novel "Skateboard Renegade" to relate velocity to real life...
