According to publisher’s materials, TOPS offers a series of home experiments and “the best science projects for parents, teachers and students that are simple to do. Our fun science activities can be done with simple things that are probably already in your home or classroom.” The experiments cover Physics, Chemistry, Life Sciences, and Math.
Before investing in any homeschooling resources, please read
"How to Choose the Best Homeschool Curriculum."
Cons: Probably more fun if used in a group setting
Grades Used: 4,5,6,7th
Currently using Tops for Adhesion/Cohesion, but have done CORN & BEANS and Radishes. Causes the child to really think about their predictions/outcomes. Even if the experiments don’t work out as it they should, you’re taught to view that as a learning point.
