I've mentioned previously that our neighbor is a biology professor at Tufts University who has created a new secular science website, SciSpark, with resources for homeschoolers and others who want to augment their science curriculum. SciSpark is geared primarily toward middle-schoolers but can be adapted for all science learners. With hands-on activities and experiments, the goal is to help students think like a scientist.
SciSpark is now offering a free 3-month trial membership, which includes the report, "7 Tips to Help Home Schooling Parents Teach Science with Confidence."
Check-out SciSpark to see if it will be a good fit for your homeschoolers!
