What are Gizmos?
Grades 3-12
ExploreLearning Gizmos are award-winning virtual math and science simulations that bring research-proven instructional strategies to life. With more than 550 Gizmos and STEM Cases, students dig deeper into math and science topics through real-life problem-solving.
Each Gizmo comes with extensive teaching resources (like pre-made, customizable lesson materials and professional development) for easy planning and implementation.
A perfect fit
Aligned to the South Dakota Student Learning Standards for math and science and Next Generation Science Standards (NGSS), Gizmos help students prepare and succeed on end-of-year summative assessments.
Instead of skimming the surface, in-depth visualization and data analytics tools help students develop a conceptual understanding of topics as they capture and compare experiment results, make predictions, and share findings with others.
5th Grade Science Question
In the Chesapeake Bay, a clam is seen with its siphon extended, which is a body part used to feed on phytoplankton in the water. Later, a blue crab and a cownose ray are seen eating the clams.
Phytoplankton use energy from sunlight to make food.
Figure 1 shows pictures of phytoplankton, a clam with its siphon extended, a blue crab, and a cownose ray.
Your Task:
Model and describe how matter flows among phytoplankton, blue crabs, and cownose rays.
