- Precision-ground edges
- Our most popular microscope slides
Truly at the top of its class, each Carolina® glass slide preparation is precleaned and individually selected for uniform quality. Our slides are made from the finest sheet glass, have precision-ground edges, and are annealed to minimize chipping and breaking. Size, 25 x 75 mm; thickness, 0.8–1.00 mm. Box of 36.
Quantity price breaks are available for large orders.
Life size. This cross-sectional human heart model comes with both sides labeled for study. One side shows the chambers of the heart, while the other side shows the valves. Activity guide with detailed information about the heart and how it functions is included. Size, 5" L.
- Perfect for science fair projects
- Super-fast generation time
- Interdisciplinary use
Brassica rapa. Wisconsin Fast Plants® polycots sprout more than 2 cotyledon leaves. The trait is easy to identify and visible immediately after germination. A relatively rare trait in nature, this advanced research stock was developed to investigate the heritability of the easily observable seedling trait (3 or more cotyledons) in a population of Fast Plants®. The generation resulting from these seeds will express approximately 30% polycots. Selection for the polycot trait will produce increased polycot frequency in subsequent generations. Main uses include selection studies. Pack of 100 seeds.
Great for small groups or for students who are learning from home!
Grades 612. Students race to the finish with balloon-powered race cars and Newton's laws of motion. They design, build, and test a prototype race car, and then explore how changes to the wheels, body, and balloon alter performance. This hands-on kit gives students the opportunity to learn how to design to overcome friction and stabilizing forces. It includes activity instructions and enough safe-at-home materials for up to 3 design teams.
Provide a hands-on learning experience about the skeletal system with this 41-piece skeleton. Half of the skeleton includes painted-on origin and insertion points to show the interactions between muscles and bones within the body. Joints are articulated to show movement as well. Includes display stand and guide with skeleton facts. Size, 9-1/2" H when assembled; perfect for a single student or a small group.
Age 10 and up. Design creative projects with the Crazy Circuits® Starter Set by following online project guides and educational resources or by creating your own designs. Add Crazy Circuits® parts to any LEGO® project to make it light up. Using the set's special conductive Maker Tape, press the Crazy Circuits® parts into place. The included conductive thread can be used to create fun wearables as well.
This set covers topics such as circuitry, logic, sewable technology, art, and design. Crazy Circuits® materials require no soldering or preparation, are compatible with LEGO® and similar brick building systems, and work right out of the box.
Exploring electricity and magnetism is a snap with Snap Circuits®
Snap Circuits® uses building pieces with snaps that enable students to assemble electronic circuits on a simple rows-and-columns base grid that functions like a printed circuit board. Each component has a distinct function and is easily identified by color. With this hands-on kit, students can learn about the relationship between electricity and magnetism and how switches operate to control the lights in their homes. Requires 4 AA batteries (not included).
- Build over 85 projects with over 45 included parts (lamps, switches, magnets, and more!)
- Inspire students to learn with the included STEM-focused educational manual
Explore hydroponics and explain its uses and limitations as a tool to help sustain human populations and manage natural resources. In this investigation, students design a solution for producing enough food for growing populations and the shift from rural to urban communities. They grow plants hydroponically in a modified ebb and flow system, analyze data from their hydroponic systems, and make recommendations about using hydroponics.
Curriculum Connection
While designed for a stand-alone earth science course, this series of activities could be incorporated into a high school biology course.
Time Requirements
Teacher prep, 60 minutes. Completing the activities, approximately 2 weeks1 day to set up investigation 1 (60 minutes), periodic monitoring for 2 weeks (5 minutes per day), 1 day for investigation 2 (60 minutes), and 1 day for analysis (60 minutes).
Digital Resources
Includes 1-year access to digital resources that support 3-dimensional instruction for NGSS. Digital resources may include a teacher manual and student guide, pre-lab activities and setup videos, phenomenon videos, simulations, and post-lab analysis and assessments.
Performance Expectation(s)
HS-ESS3-3. Create a computational simulation to illustrate the relationships among the management of natural resources, the sustainability of human populations, and biodiversity.
