Ready for Back-to-School?
Download the Free 2025 3D Investigation Sampler
Get inspired with three brand-new investigations that support three-dimensional learning in biology, chemistry, and physics. Each one is designed to spark curiosity with real-world phenomena, hands-on data collection, and meaningful student sensemaking.
Whether you use them now or later in the year, these free experiments are easy to implement and cover core science concepts.
In these investigations, students explore:
- Biology: What can a sealed biosphere reveal about life on Earth—and beyond? Explore gas exchange in photosynthesis and cellular respiration.
- Chemistry: Why does tea change color when lemon juice is added? Investigate pH, chemical equilibrium, and Le Châtelier’s principle.
- Physics: What forces are at play when an elevator goes up? Model mass, motion, and Newton’s second law with an Atwood’s machine.
Featured Products
Go Direct® CO2 Gas Sensor
The Go Direct CO2 Gas Sensor measures gaseous carbon dioxide concentration levels, air temperature, and relative humidity. This versatile sensor can be used in a wide range of biology experiments, from exploring photosynthesis and respiration to investigating yeast fermentation.
GDX-CO2

Go Direct SpectroVis® Plus Spectrophotometer
The Go Direct SpectroVis Plus Spectrophotometer gives students a hands-on introduction to spectroscopy with fast, wireless data collection. Use it in a range of applications—from chemistry and biology to environmental and physical science. Students can explore absorbance, percent transmittance, fluorescence, or intensity as they investigate reaction rates or determine concentration using Beer’s law.
GDX-SVISPL
$479
Go Direct Photogate
The Go Direct Photogate is a double-gate sensor that students can use to easily and accurately measure velocity and acceleration. Ideal for investigating the motion of an object in free fall, rolling objects, collisions, and pendulums, without needing to know anything about the geometry of the object.
GDX-VPG
