Pre-K science classes close to DC?

[Anonymous]

My 4 year old went to a sample Mini Einstein class out at Ideaventions in Oakton, Va. and loved it (the topic that day was fossils) but we live in DC and there is no way I am driving 40 minutes each way for a Saturday class every week.
Any recommendations out there for a weekend pre-K science enrichment program that is closer in?

I am not sure of the age range, but I signed my six year old up for a Mad Science Camp this summer - http://www.madscience.com/ I hope this is of help.
