Several studies have showed the subsistence, even in students enrolled in scientific degree courses, of spontaneous ideas regarding the motion of bodies that conflict with Newton's laws. One of the causes is related to the intuitive preconceptions that students have about the role of friction as a force. In fact, in real world novices do not…

This article is the first in a new series of hands-on activities designed especially for early childhood students to encourage their natural curiosity and promote development of scientific thinking. The activity presented was created to help children learn how to make scientific observations using their senses. Children develop science inquiry…

The dramatic decrease in the cost of sequencing a human genome is leading to an era in which a wide range of students will benefit from having an understanding of human genetic variation. Since over 90% of sequence variation between humans is in the form of single nucleotide polymorphisms (SNPs), a laboratory exercise has been devised in order to…

The purpose of this research is to evaluate the effectiveness of the activities, which are prepared by teaching techniques that support scientific creativity, on the scientific creativity levels of prospective pre-school teachers. In the research, combined design is used, which is one of the mixed research approaches. The study group of the…

The purpose of this study was to determine the effects of nature-based education on the attitudes of 7th grade students towards the environment and living organisms as well as to assess the affective tendency of this education on the students. The study was carried out with 30 7th grade students at an elementary school. For this purpose, scales…

This article describes how to construct a simple, inexpensive, and robust colorimeter from a few Lego bricks, in which one light-emitting diode (LED) is used as a light source and a second LED as a light detector. The colorimeter is suited to various grades and curricula.

In this article, Bill Robinson describes the three main classifications of gait for animals: (1) Plantigrade--animals that walk on their entire foot; (2) Digitigrade--animals that walk on their "toes"; and (3) Unguligrade--animals that walk on the tips of their toes or hooves. Robinson explains each gait in great detail, but leaves his…

Stability is often an important consideration in both static and dynamic systems. While introductory students soon grasp the balance of forces required for constant velocity motion, it generally takes longer for them to reliably identify the various torques involved in producing rotational equilibrium. Accelerating systems have the additional…

Light refracts as it travels from one medium to another. The angle of incidence "i" and the angle of refraction "r" are related by Snell's law, sin"i" ÷ sin"r"="k," where "k" is a constant. The diagram in Fig. 1 shows a geometric representation of the formula for light passing from…

Many of us have grabbed two pieces of aluminum foil and a paper towel, quickly sandwiched them together, and exclaimed in lecture, "Look! It's easy to make a capacitor!" Then we move on from there, calculating things such as capacitances with various dielectrics or plate sizes, the capacitance of capacitor networks, RC circuits,…

In this activity, students are given the opportunity to combine skills in math and geometry for a biology lesson in the cell cycle. Students utilize the data they collect and analyze from an online onion-root-tip activity to create a paper-plate time clock representing a 24-hour cell cycle. By dividing the paper plate into appropriate phases of…

The aim of the study was to explore the types and sources of positive emotions experienced by first year university students studying to become primary school teachers, during collaborative science learning. Fun science activities, designed to enhance students' motivation for science, provided the context for examining the relationship between…

Ramps and Pathways (R&P) early physical science activities enable educators and young children (3-8 years) to explore and investigate what happens as marbles and rolling objects are released on constructed ramp structures and pathways using wooden cove molding. The R&P project challenged educators to transform their views of early science…

This qualitative study explores the in- and out-of-school experiences that could have influenced elementary preservice teachers? beliefs and attitudes toward learning and teaching science. Participants were 126 Latina/o EC-6 preservice teachers in the context of a 16-week undergraduate level elementary methods course. Data sources consisted of…

A shortcoming of Massive Open Online Courses (MOOCs) is the lack of substantive integration of hands-on activities into online classrooms. We conducted a randomised control trial (RCT) in a MOOC where we sent the treatment group at-home lab kits with which they could perform experiments in their own homes. In our intervention research, we found…
