Brown, Patrick L.; Concannon, James – Science Activities: Classroom Projects and Curriculum Ideas, 2016
One tried-and-true way to hook students' attention and promote long-lasting understanding is to sequence science instruction in an explore-before-explain instructional sequence. In these lessons for the second through sixth grade band, elementary students investigate the interaction between "cold" and "hot" substances and…

McCoy, Ann; Barnett, Joann; Stine, Tammy – Teaching Children Mathematics, 2016
Without a doubt, fractions prove to be a stumbling block for many children. Researchers have suggested a variety of explanations for why this is the case. The introduction of symbolization and operations before the development of conceptual understanding of fractions, a lack of understanding of the role of the numerator and denominator, and an…

Arnone, Kathryn; Morris, Bethany – Science and Children, 2014
It seems each new school year brings its own opportunities to grow as an educator. As teachers in a STEM focused school that serves primarily at-risk students, the authors face a new challenge in rethinking their instruction to align with the "Next Generation Science Standards". This involves changing the focus of units previously taught…

Becklin, Katie M. – American Biology Teacher, 2008
Plants and insects share a long evolutionary history characterized by relationships that affect individual, population, and community dynamics. Plant-herbivore interactions are a prominent feature of this evolutionary history; it is by plant-herbivore interactions that energy is transferred from primary producers to the rest of the food web. Not…

Pierzynski, Gary M.; Vaillant, Grace C. – Journal of Natural Resources and Life Sciences Education, 2006
The cumulative result of almost 100 years of mining, milling, and smelting has left areas of Jasper County, Missouri, contaminated with high levels of the trace metals Pb, Cd, and Zn. The site was listed on the National Priorities List in 1990 and is now known as the Jasper County or Oronogo-Duenweg Mining Belt Superfund Site. The U.S.…

De Jong, Marvin L. – Physics Teacher, 2006
Oceantides are not typically high in our consciousness here in Missouri, but in teaching astronomy and physical science the subject always comes up, and teachers of physical science and astronomy are all quite familiar with the textbook explanations. Our goal here is not to explain tides but to make some suggestions about how, on their own,…

Swift, Theresa M.; Watkins, Steve E. – Journal of STEM Education: Innovations and Research, 2004
Student motivation for and proficiency in science and mathematics begin in the early grades. Level-appropriate resources and professional outreach activities are as beneficial for teachers and students at elementary levels as for higher levels. Engineering applications can be effective vehicles for giving students hands-on exposure to technical…
