How many of these items do you already have? We’ve tried to keep it simple for you by making the majority of the items things most people have within reach (both physically and budget-wise).
You do not need to do ALL the experiments – just pick the ones you want to do by first checking out the experiment videos. Note the activities that you already have the supplies for and start with those. When you are ready for more, make a note of the supplies from this list.

Oops! Sorry about that – I’ve uploaded the correct file, everything should be fixed now.
The shopping link above only takes you to a page that says the following and doesn’t actually have the shopping list on it. I just copied and pasted the list into a word document to print it out no biggie but I think that’s what everyone is talking about.
Unit 17:
Life Science Part 2
http://www.ScienceLearningSpace.com
Appropriate for Grades:
Grades K-8 (see notes on each lesson)
Duration: 3-25 hours, depending on how many activities you do!
Living things are all around us. Sometimes the living things we notice the
most are animals, whether its birds chirping in the trees, our pet dogs, or
even our fellow human beings. However, most living things are not
animals. In these sections, we will learn about bacteria, archae, fungi,
protists, and plants. These organisms are extremely important to learn
about. They make life possible for animals, including human beings, by
keeping soil ready for growth, and providing oxygen for our survival. No life
would be possible without these remarkable organisms.
Science Camp is June 1st – Aug 31
When is your science camp?
I am not sure if you are referring to how to prep the agar itself or the dish, so here is prep instructions for both:
Since agar is used to grow bacteria, all you have to do is warm it until it melts (you can place it in a hot water bath or microwave it on high for 30 seconds) and then fill up your petri dish. If it’s dehydrated, then dissolve 1 teaspoon agar with 1/4 – 1/2 cup water and bring it to a boil slowly to re-hydrate.
For the dish, you want to just cover the bottom and let it stand until the agar is firm. Store it upside down in the fridge until you’re ready to use it. When you’re ready to use it, pull it out and use a sterile q-tip to take a bacteria sample (like from the inside of your cheek) and gently rub it in a couple of zig-zag strokes over the agar and then stick the lid on and put it in a warm, damp area for a couple of days. You can peek in every day to see how it’s growing and record your information in your science journal.
When you’re done, get a grown up to put a tablespoon of bleach in with the bacteria culture, seal it up in a plastic bag and throw it in the trash.
How do I prepare the Petri dish using agar powder?
What kind of problem did you have with this list? Is there something missing, or incorrect?
I had problems with the shopping list too. Cheers
please correct the link to the shopping list. it does not show a condensed list of materials as #16 does. Thank you
