We started in the fall working on kindergarten science activities from the MythBusters Science Fair Books. They were fantastic for monthly lessons of blowing stuff up, which happens to be what boys love. Right now we're working our way through 4 months of Lego Simple Machines as our monthly science activity with our group.
Since we tend to love gardening and plants with our large backyard garden we invested in about 4500 ladybugs to release last summer. It seemed only natural that this spring we watch how ladybugs grow through their life cycle. I hopped on InsectLore.com to find some ladybug grub and I was not disappointed. We already had a ladybug land from last year and a refill of grub was a perfect solution. I love that they offer the "refill". Perhaps this will be a yearly activity for us from here on out. Of course, my eye was also caught by other insects as I was searching the site for more learning experiences. Our shopping cart ended up containing ladybug grub, caterpillars and a butterfly garden, millworms and a praying mantis egg sack. This year we are trying again with a praying mantis egg sac (last year we ordered one but it didn't hatch). In fact, last year we had a most awful time with a different insect company and won't ever use them again, oiy! Millworms are an interesting addition to our insect collection, particularly since there are chickens around that would benefit from such a tasty snack. Caterpillars was a no-brainer since they are so common.
It is really hard to get pictures of the ladybugs. I mean - REALLY hard. They are itty bitty and trying to get a focus on them is just not happening, but trust us that it's really cool.
