We are growing frogs.

Here is the life cycle we have amassed so far.

Stage 7: There are no more gills and the body is larger. The eyes are also visible here.

Stage 6: The taddie develops gills.

Stage 5: Tail shape is changing. More growth.

Stage 4: Fully hatched. They eat boiled lettuce.

Stage 3:

Stage 2: Eggs are changing shape.

This happened in a very short amount of time. When the weather is cold, it can take two years for a frog to reach maturity. When it is warm (like my house), it can take weeks.

We went frog hunting the other day and couldn’t find any. We could hear them croaking very loudly in the distance but no matter how far we walked they were always just a little bit further.

After admitting defeat, we started walking home.

I spotted this clump of frog eggs in the ditch. I thought, if I can not find some, I will grow some.

Stage 1: In natural habitat (I only took a very small amount -this is what was left when I was done).

The bright “star” is actually the planet Venus and the moon, well, I am not telling you which one the moon is. You should know that much. Ha ha ha.

That was taken on May 15th.

On May 16th the moon would have been seen above Venus. But I couldn’t see it because my sky was too overcast.

This astronomy stuff is fun!

A while ago I was raving about our reuse centre and all of the great crafting supplies we have gotten from there. We have gotten everything from sewing patterns to plaster to paper plates to envelopes for my home made cards to zippers to plastic egg cartons (which I use for mixing paint).

And today I am wanting to rave about our thrift store. Aside from some wonderful resource books I have also found science kits and glasses for my kids. I wanted some glass cups (since I hate plastic so much) for my boys to use now that they are older and have gotten over the butter fingers part of childhood. But I wanted glasses that I wouldn’t mind if they got broken accidentally. They had a piles of glasses at $0.49 a piece. So I bought a matching set of eight and now I can store some of the plastic cups. Also, the plastic cups don’t clean well in my dishwasher and having my boys using glass cups will mean I can clean their cups in the dishwasher. And that saves me time!

One of the science kits we bought was a plant growing kit. Everything was still in the original packaging. It came with “hot house” tubes and peat moss pellets and even plaster for doing demonstrations about how seeds can crack through hard mediums like concrete. There was more to it than just that and it was worth every penny of that $2.99 I spent on it.

You can see a seed in peat above and the picture on the side is the pinto that we started many weeks ago and the other is one of the “hot house” seed things we have growing.

It’s hard to see as it’s in the background but it’ll be the same kind of idea as the time I grew seeds in a ziploc bag.

The other set I picked up was a large chemistry set for five bucks. It has many, many different experiments to try. Everything from basic chemical reactions to testing pH to creating reactions using electricity etc.

I also found three boxes of prepared slides for a microscope. The slides contain bits of plants and bugs. I don’t have a microscope yet but I didn’t want to pass on those slides.
