This lesson discusses solenoids. Students learn how to calculate the magnetic field along the axis of a solenoid and complete an activity exploring the magnetic field of a metal slinky. Solenoids form the basis for the magnet of an MRI. Exploring the properties of this solenoid helps students understand the MRI machine.

This short video and interactive assessment activity is designed to teach second graders about identifying and naming 3d figures.

This short video and interactive assessment activity is designed to teach third graders about identifying and naming 3d figures.

Students are given a variety of materials and asked to identify each material as a solid, liquid or gas. They use their five senses ‰ŰÓ sight, sound, smell, texture and taste ‰ŰÓ to identify the other characteristics of each item.

In this lesson, students explore solid waste and its effects on the environment. They will collect classroom trash for analysis and build model landfills in order to understand the process and impact of solid waste management. Students will understand the role of engineers in solid waste management.

This short video and interactive assessment activity is designed to teach second graders about solving decimal word puzzles.

This short video and interactive assessment activity is designed to teach fourth graders about solving length and distance problems involving time - word problems.

This short video and interactive assessment activity is designed to teach third graders about solving multi-step problems involving time.

This is a lesson about using the light from the star during an occultation event to identify the atmosphere of a planet. Learners will add and subtract light curves (presented as a series of geometrical shapes) to understand how this could occur. The activity is part of Project Spectra, a science and engineering program for middle-high school students, focusing on how light is used to explore the Solar System.

This short video and interactive assessment activity is designed to teach fourth graders about solving for elapsed time related to rate.

This short video and interactive assessment activity is designed to teach third graders about solving for elapsed time related to rate.

This short video and interactive assessment activity is designed to teach third graders about solving for elapsed time in a sequence of events - word problems.

Sal solves a linear system with 3 variables by representing it with an augmented matrix and bringing the matrix to reduced row-echelon form. Gaussian Elimination is the method, reduced row echelon is just the final result.

In this video segment, poet Sonia Sanchez recites her poem Malcolm, as a eulogy to the slain civil rights leader, Malcolm X. Recorded for Eyes on the Prize.

Poet Sonia Sanchez, interviewed here for Eyes on the Prize, describes what the outspoken civil rights leader Malcolm X represented to African Americans in the 1960s. ***Access to Teacher's Domain content now requires free login to PBS Learning Media.

In this project, students will use knowledge of electricity and electromagnetism to collaboratively design and test a model of a magnetic recycling sorter. They will evaluate the performance of their models and propose further modifications based on the output of their magnetic device measured in mT using a Vernier probe. They will also physically test their magnets on a model of a conveyor belt containing recyclable items. Students will track their data from both tests, with the ultimate goal of creating the strongest and most effective magnet with given materials. Finally, students will present their findings and proposed final design to peers and community partners involved in the recycling industry. The entire process takes about 6 weeks. The unit is a great fit for standards within energy and engineering & design.

Students are introduced to the sound environment as an important aspect of a room or building. Several examples of acoustical engineering design for varied environments are presented. Students learn the connections between the science of sound waves and engineering design for sound environments.

In this lesson, students are introduced to communications engineers as people who enable long-range communication. In the lesson demonstration, students discuss the tendency of sound to diminish with distance and model this phenomenon using a slinky. Finally, Alexander Graham Bell is introduced as the inventor of the telephone and a pioneer in communications engineering.

In this unit of study students learn about sound waves. This unit integrates nine STEM attributes and was developed as part of the South Metro-Salem STEM Partnership's Teacher Leadership Team. Any instructional materials are included within this unit of study.

Sounder & Friends is a resource that focuses on phonological awareness & the Science of Reading. It has engaging activities and characters and the Instagram page also does weekly posts that break down different elements of reading and explain them clearly. This could be a great resource for teachers and families!
