In this hands-on activity rolling a ball down an incline and having it collide into a cup the concepts of mechanical energy, work and power, momentum, and friction are all demonstrated. During the activity, students take measurements and use equations that describe these energy of motion concepts to calculate unknown variables, and review the relationships between these concepts.

Percussionist Steven Angel has developed an innovative program that uses rhythm to help struggling students improve their reading fluency and comprehension. Deceptively simple -- a facilitator taps out a basic rhythm while students read aloud -- the method relaxes students, helps them focus, and is effective in after-school intervention programs as well as traditional classrooms.

This is a short experimental study of what happens to aluminum hydroxide, silicic acid, magnesium oxide, and calcium carbonate (or reagents of instructors choice) when they are heated to 110 and 1200 degrees.
Students determine the formula and calculate the mole percent and weight percent of each element and oxide in each reagent. They heat the samples and calculate percentage weight loss or gain. Finally, they write a lab report summarizing their results.
Be sure to have students save their samples for later use in a lab that introduces X-ray diffraction.

Really Ancient Fossils STEM Kit. The Natural Sciences Education & Outreach Center …
Really Ancient Fossils STEM Kit. The Natural Sciences Education & Outreach Center collaborates with CSU faculty, National Parks and citizen science programs to translate their current scientific research into unique STEM experiences for students in the form of Educational Kits that can be checked out. Each kit contains just about all of the materials needed (minus common things like water and paper towels) to explore some really interesting scientific research topics.The kits are available for teachers and informal educators in Colorado to check out for a duration of a week by submitting either a local pickup form or a delivery form available at the linked website. Due to the extreme weight of the sand used in this Kit, local pickup is the only option. This kit is provided free for educational use. This kit is also available in Spanish.

This activity engages learners to investigate the impact of Earth's tilt and the angle of solar insolation as the reason for seasons by doing a series of hands-on activities that include scale models. Students plot the path of the Sun's apparent movement across the sky on two days separated by three months of time.
