Adadan, Emine; Akaygun, Sevil; Sanyal, Amitav – Science Activities: Classroom Projects and Curriculum Ideas, 2017
This interdisciplinary scientific inquiry lesson specifically utilizes the 5E learning cycle to engage high school students in an investigation on size-dependent properties of matter. In particular, this inquiry lesson focuses on a biologically relevant phenomenon, namely accessibility to a pharmaceutical drug with respect to the size of the pill.…

Kennon, James Tillman; Fong, Bryant; Grippo, Anne – Science Activities: Classroom Projects and Curriculum Ideas, 2016
Sunscreens have different levels of protection, measured most commonly with the sun protection factor (SPF). Students initially believed higher SPF factors mean greater sun protection and learned through this activity that higher SPF does not mean greater protection. Students analyzed the amount of ultraviolet radiation (UVR) protection and…

Rose, Chantelle M.; Adams, Jacqueline M.; Hinchey, Elizabeth K.; Nestlerode, Janet A.; Patterson, Mark R. – Science Activities: Classroom Projects and Curriculum Ideas, 2013
Pressure increases rapidly with depth in a water body. Ocean and Great Lakes scientists often use this physical feature of water as the basis of a fun pastime performed aboard research vessels around the world: the shrinking of polystyrene cups. Depending on the depth to which the cups are deployed, the results can be quite striking! Capitalizing…

Brown, Todd; Brown, Katrina; Barnot, Vickilyn – Science Activities: Classroom Projects and Curriculum Ideas, 2012
Reaction time, the time between a stimulus and a person's reaction to it, is a concept familiar to most teenagers, particularly in the context of driving. We describe a simple inexpensive activity that utilizes students' creativity and invokes the scientific method in order to explore reaction time. The goal of the activity is to give students a…

Haverkort-Yeh, Roxanne Dominique; Tamaru, Clyde S.; Gorospe, Kelvin Dalauta; Rivera, Malia Ana J. – Science Activities: Classroom Projects and Curriculum Ideas, 2013
As a result of shifting marine environmental conditions caused by global climate change and localized water pollution, marine organisms are becoming increasingly exposed to changing water quality conditions. For example, they are exposed to more extreme salinity fluctuations as a result of heavier rainfall, melting polar caps, or extreme droughts.…

Rascoe, Barbara – Science Activities: Classroom Projects and Curriculum Ideas, 2010
This lab activity uses inquiry to help students define heat. It is generic in that it can be used to introduce a plethora of science content across middle and high school grade levels and across science disciplines that include biology, Earth and space science, and physical science. Even though heat is a universal science phenomenon that is…

Gates, Joshua – Science Activities: Classroom Projects and Curriculum Ideas, 2009
For this experiment, students are divided into 2 groups and presented with a static equilibrium force-balance problem to solve. One group works entirely experimentally and the other group theoretically, using Newton's laws. The groups present their seemingly dissimilar results and must reconcile them through discussion. (Contains 3 figures.)

Campbell, Todd; Neilson, Drew – Science Activities: Classroom Projects and Curriculum Ideas, 2009
Encouraging students to share their ideas, design mechanisms for testing ideas, and make conclusions about the validity of their ideas on the basis of evidence collected can enhance teaching about friction. The authors focus on teaching science content and science processes in a holistic manner so that students develop enduring understandings of…

Baker, William P.; Jones, Carleton "Buck"; Hull, Elizabeth – Science Activities: Classroom Projects and Curriculum Ideas, 2007
This simple but effective laboratory exercise helps students understand the concept of protein domain function. They use foam beads, Styrofoam craft balls, and pipe cleaners to explore how domains within protein active sites interact to form a functional protein. The activity allows students to gain content mastery and an understanding of the…

Buczynski, Sandy – Science Activities: Classroom Projects and Curriculum Ideas, 2007
In these activities, middle school and high school students examine the threat of nonnative plant species to Hawaiian ecosystems. Students explore different viewpoints on alien plants and consider how beliefs and attitudes may affect others' decisions concerning nonnative plant species. Students also identify invasive plant characteristics and…

Cheung, Derek – Science Activities: Classroom Projects and Curriculum Ideas, 2005
This authentic inquiry-based chemistry experiment provides high school students with an opportunity to investigate the effect of toothpastes on the rate of tooth decay. Students need to design and carry out a fair test to compare the effects of different brands of toothpaste. The author has developed rubrics for assessing students' planning skills…

Rye, James A.; Smolski, Stefan – Science Activities: Classroom Projects and Curriculum Ideas, 2007
Teachers can use pedometers to facilitate inquiry learning and show students the need for mathematics in scientific investigation. The authors conducted activities with secondary students that investigated intake and expenditure components of the energy balance algorithm, which led to inquiries about pedometers and related data. By investigating…
