As the number of jobs in the science, technology, engineering, mathematics (STEM) workforce grows exponentially, there has never been a more important time to provide students with real-world learning opportunities that have 21st century implications. Measuring things that matter is a fundamental skill that formulates the backbone of many concepts…

Magnifying objects can foster wonder in young children because they can make new observations of familiar things. This activity helps children explore common substances and familiar materials using a magnifying glass. Magnification can help people observe living things more closely providing a link to the work of scientists and the magnifying…

If you think physics is only for older children, think again. Much of the playtime of young children is filled with exploring--and wondering about and informally investigating--the way objects, especially toys, move. How forces affect objects, including: change in position, motion, and shape are fundamental to the big ideas in physics. This…

Students often hold misconceptions about insulation, largely because they put on clothes to keep themselves warm--at least in winter in the cooler regions of Australia. The following activity is designed to identify students' misconceptions about insulation and provide an engaging, evidence-based activity to help address these misconceptions using…

When teaching how "tension" and "compression" relate to geometrical structures such as bridges, arches, and domes, The author shows a picture of the Notre Dame Cathedral in Paris, completed in the 14th century, and presents a lesson on using the curve called a catenary to explain how he teaches about tension and compression…

Materials are all around us and the importance of supporting children to understand the vast array of different types of materials is recognised at all key stages in the science National Curriculum for England. Ensuring that children connect concepts taught in key stages 1 and 2 (ages 5-11) is the starting point in helping children to comprehend…

As teachers the authors aim to inspire and instill curiosity while teaching science and this can be enriched by tapping into pupils' interest in what is happening in the outside world. At Whitehill Junior School, they endeavor to make the most of real-life events and seek to foster meaningful links with scientists and engineers to help bring STEM…

In this article, two lessons are introduced in which students examine Arctic lake sediments from Lake El'gygytgyn in Russia and discover a climate signal in a lake or pond near their own school. The lessons allow students to experience fieldwork, understand lab procedure, practice basic measurement and observation skills, and learn how to…

EngQuest, an initiative of Engineers Australia, provides an exciting, non-competitive way for students to participate in free, fun and educational engineering activities involving mathematics, science and technology. This article describes a project designed to teach middle school students how to construct a water catchment system. Water…

Plants are often overlooked in favour of animals when teaching about living things. Focusing on familiar animals that share human characteristics helps young children learn about similar features. Examining plants for their differences, though, helps foster wonder. In the author's experience, children find it intriguing that plants need…

SOLO taxonomy models the levels of understanding within a topic; its hierarchal nature can support progression and challenge. Flipped learning is a strategy that uses homework to build background knowledge, thereby maximising the impact of lesson time. Both flipped learning and SOLO taxonomy can be used to support student learning, either combined…

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…

A simple, reliable, and cost-effective experiment is presented in which students synthesized citrate-capped gold nanoparticles (GNPs), functionalized them with poly(ethylene glycol) (PEG), and transferred the PEG-GNPs from water to the organic phase dichloromethane. The experiment introduces students to nanotechnology with foci on important…

The concept of specificity of enzyme action can potentially be abstract for some students as they fail to appreciate how the three-dimensional configuration of enzymes and the active sites confer perfect fit for specific substrates. In science text books, the specificity of enzyme-substrate binding is typically likened to the action of a lock and…

To promote teaching science through inquiry, the author wanted to use his experience in the Galápagos to design a lesson that allows students to immerse themselves in the essential science and engineering practices identified in the "Next Generation Science Standards," as they ask questions; analyze and interpret data; engage in argument…
