Interactive and Experiential Science Tools

What goes on aboard the International Space Station (ISS)? This question has been asked in many science classrooms.

We all know that, launched in 1998, the ISS is an international partnership of countries and their space agencies which provides and operates the ISS. The principals partners are the space agencies of the United States, Russia, Europe, Japan, and Canada. ISS is the largest space station ever constructed, and continues to be assembled in orbit and has been visited by astronauts from 18 countries.

Since the early 2000, thousands of experiments have been conducted aboard the ISS, including hundreds related to educational activities. From Story Time From Space to Gecko Gripper adhesives that use microscopic angled hairs to stick to surfaces using van der Waals forces. You can see the complete list here.

The Nation’s Report Card on Science is out. The average NAEP science scores for the nation increased 4 points between 2009 and 2015 in both grades 4 and 8, but did not change significantly at grade 12. Scores for most student groups at grades 4 and 8 were higher in 2015 compared to 2009, but were not significantly different at grade 12. At grades 4 and 8, Black and Hispanic students made greater gains than White students, causing the achievement gap to narrow in comparison to 2009. 

Compared to 2009, scores were higher at grades 4 and 8 in all three science content areas (physical science, life science, and Earth and space sciences) in 2015, while there were no significant changes in content area scores at grade 12. Read more.
