Earth, Ocean and Space Activities for Earth Science Classrooms

 Remember those special times when ​​you actually achieved and learned more when encouraged to work together with friends and classmates in solving challenging problems? Strong students gained leadership skills and confidence by assisting friends who were experiencing difficulty in completing those tasks. Our games and labs are specially designed for this type of cooperative, hands-on learning opportunities.

"Love your materials!"
Sheree B., Science Olympiad Coach, Macomb, MI

​“Thank you for being a most valuable resource for our Science Olympiad team. Your materials make students think but do so in ways that are not intimidating or round-about. You write with the students’ understanding in mind.”
David O’Shields, Science Olympiad Coach

“Thank you for producing such great products. I look forward to seeing what you have at the coaches’ clinics each year.”
Jason Miller, Friendship Christian School

“Thank you so much, Linder. Your products are so helpful to our kids. The time and effort you put into your products have helped make our team successful, and we love doing Science Olympiad as a result.”

"Thank you for going out of your way to help us acquire relevant specimens that fit our budget -- not only for the Fossils event, but for Rocks & Minerals event as well. Your specimens – both R&M and Fossils -- are by far the best quality ones that I have been able to find at an affordable price. The excellent quality of your specimens definitely played a part in gaining my students’ enthusiasm. Thank you also for your Games. My students enjoy them and end up learning useful nuggets of information. Last but not least, thank you for the sample tests. Especially last year when Fossils tests were hard to come by for a youngish team. Your tests gave my students a solid start. Please keep up the good work."
