Choosing Between Them
If you want the most versatile option, I highly recommend the Mega Science Lab as it provides the most content for your money. For children who prefer specific themes, the Gross Science Kit works well for messy fun, while the Science Magic Kit is ideal for the performer in your life. I find that picking the kit based on the child's personality is more effective than looking for the highest experiment count alone.
You should keep in mind that almost all of these sets require common household items such as water, vinegar, or vegetable oil to complete the full list of activities. Be prepared to supplement the box contents from your own pantry, as the included chemicals are usually just the catalysts for the fun.
