The Home Scientist, LLC offers proven science curricula and kits that make it easy and affordable to teach high school science lab courses at home. THS science kits are designed to provide a rigorous, comprehensive laboratory component that can be used with nearly any high school science text, at the standard, honors, or advanced level. We recognize that teaching high school science courses at home can be challenging, both in terms of cost and difficulty. Our kits address both of those issues. Compare the scope, contents, and prices of our kits with competing kits, and we think you'll find that our kits are the hands-down winners in terms of bang for the buck. Each of our kits provides enough labs for a lab-intensive full-year course. Our kits include complete, detailed instructions, as well as answers to the review questions at the end of each lab session. Even if you've never taught a science lab course before, we think you'll find it surprisingly easy to do so with our kits.
FREE SHIPPING ON ALL US ORDERS EXTENDED THROUGH DECEMBER 16, 2024! DISCOUNTED SHIPPING RATES ARE AVAILABLE FOR INTERNATIONAL ORDERS. CONTACT US FOR DETAILS.
Every THS science kit is designed with the following goals:
Our Biology, Chemistry, and Forensic kits will challenge your students while giving them a great learning experience.
We're here to help!
When you purchase any of our Science Kits or materials, you agree to these Terms of Use. Please Contact Us if you have any questions or concerns. Safety is ultimately your responsibility. The degree of adult supervision you require will depend on your comfort level and the maturity of your student(s). Our lab kits include corrosive, toxic, and flammable chemicals. Although the very small amounts used minimize the risks, it is still important that both teacher and student familiarize themselves with the risks and follow all safety precautions, including wearing gloves and chemical splash goggles when handling hazardous materials. The materials in this kit are not intended for use by children under 14, and must be used under the supervision of a responsible and competent adult. Our kits have been used successfully by parents whose science background varies from holding a Ph.D. in chemistry or biology to those who haven't had any exposure to science since they were taking high school science courses themselves. We make no assumptions about your level of science knowledge. The kit documentation provides complete, detailed instructions that allow you to do the lab sessions successfully regardless of your own experience.
We strive to mail kits to US addresses within 10 days of order receipt. Please allow additional time during peak order season - July thru September. Multiple kits may require additional lead time.
Hazardous material shipping regulations and the nature of the kits make it impossible for us to accept returns, so please be certain you want the kit before you order it. All sales are final.
If the kit is not completely used up, the best way to dispose of it is to give or sell it to another local homeschool family. (Do NOT ship the kit; unless you repackage the kit in accordance with all hazardous material shipping regulations, doing so may violate those regulations and get you into real trouble.) Local hazardous material disposal laws and regulations vary greatly in different jurisdictions, so if you want to remain within the letter of the law you should contact your local authorities about proper disposal methods. In practical terms, the amounts of hazardous chemicals included in the kits are small enough that you can simply flush them down the drain with copious running water.
By placing an order for a kit or kits to be shipped to an address outside the US, you acknowledge that you understand and agree to the following terms and conditions: The contents of the international version of our kits is very similar but not identical to the contents of the US versions. Some of the chemicals in the US version are prohibited by international hazardous materials shipping regulations. Wherever possible we have provided non-hazardous substitutes, For example, the US kits contain 6 M (34%) acetic acid, while the international version substitutes 1.7 M (9.9%) acetic acid. The International versions contain dry stains which require the addition of alcohol before use. We are unable to ship internationally sodium hydroxide solution in any concentration or amount, but you can make up your own from sodium hydroxide obtained locally under the names of "lye" or "crystal drain opener". Please contact us for more information.
You are responsible for determining whether it is legal for you to have a kit shipped to you. There are so many international jurisdictions that it's impossible for us to do so. In practice, in the past many buyers have probably ignored this issue, and we've never had any delivery problems with any of the many kits we've shipped internationally. You may (or may not) have to pay additional fees, taxes, customs duties, VAT, and so on, which are normally collected by your local postal service. We ship via USPS Priority Mail International because it is by far the least expensive method. Neither the USPS nor (to the best of our knowledge) other national postal services collect the very high customs brokerage fees often charged by UPS and other third-party shippers. Delivery times can be extended. In the US, our kits generally ship the same day the order is received or the following day, and arrive within 1 to 3 business days. For shipments to Canada, Great Britain, and Australia, 6 to 10 business days in transit is typical, and it may take longer. In particular, hold-ups in customs are unpredictable. The kit may arrive in the destination country a few days after we mail it, and then sit in customs for anything from a few hours to two weeks or more.
Although we normally ship kits to US addresses within one week of receiving the order, shipments of kits to international addresses may require additional lead time. Because we have no control over or ability to track or follow-up on international shipments, all kits shipped to addresses outside the US are FOB Pennsylvania, USA. In effect, that means our responsibility ends when we hand the package to the US Postal Service carrier. (After evaluating insurance costs and policies, we elected not to offer insurance on international shipments. It's expensive, claims are often arbitrarily denied, and even if a claim is approved it may take literally months to be paid. At that, the pay-out is often a small percentage of the actual loss, and getting even that may require hours on the phone.) We have shipped scores of kits internationally--to Canada, Europe, the Middle East, and Asia--and to date none of them has been lost or damaged. If you do experience delivery problems, which we think is unlikely, we will on request email you a PDF copy of the postage label and customs documentation that you can provide to your local post office or other authority.

The BK01A, BK01A-B, BK01A-S, and BK01A-BS Biology Kits contain all of the items listed below, except as noted. The BK01A-RK Biology Refill Kit contains chemicals only.
* BK01 kits originally included a 10-pack of pre-sterilized polystyrene (plastic) Petri dishes. Later BK01 kits substituted a 3-pack of glass Petri dishes for the plastic Petri dishes. Because of breakage problems (both during shipping and during use) current BK01A kits include a 6-pack of 50mm polypropylene (PP) Petri dishes. The PP dishes can be re-used indefinitely simply by washing them and sterilizing them in a pressure cooker (15 minutes at 15 PSI) after filling them with agar gel. Also, because they are smaller diameter (50mm versus 75mm), the PP Petri dishes use expensive agar more efficiently. A 25 mL batch of agar medium is sufficient to fill the six Petri dishes to the proper level.
1 included only in kits shipped to Hawaii (to substitute for the Rhizobia culture) 2 the book lists the BK01 kit as including amoxicillin capsules. Current BK01A kits substitute a vial of penicillin G potassium for the amoxicillin. You can substitute one heaping loose spatula spoon of penicillin G potassium powder for one 250 mg amoxicillin capsule. 3 with the exceptions of these items, the consumables in the kits should remain usable for at least two years if unopened or if carefully resealed after opening, and if stored in a cool, dark place. The Rhizobia culture, the lima bean seeds, and the yeast should remain usable for at least one year unopened. If you intend to reuse the kit for another student within two to three years, you can purchase replacements for the Rhizobia culture and the seeds at most lawn and garden stores (make sure the Rhizobia culture you purchase is compatible with lima beans), and yeast at any supermarket. Although we cannot guarantee shelf live for the BC03 Bacteria Culture because shipping and local storage conditions are beyond our control, if unopened and stored at room temperature in the dark, the BC03 culture should remain usable for at least one year and possibly several years. Do not refrigerate this culture. If you open the culture using aseptic procedures, you can recap and reseal it without significantly affecting the shelf life of the remainder. 4 not included in kits shipped to Hawaii (State regulations prohibit us from shipping Rhizobia cultures to Hawaii).

Note: We package the FK01B kit as a separate item because we've had numerous requests from home school parents who didn't want drug testing functions in the kit. Also, in some jurisdictions it's illegal for individuals to possess these drug testing reagents. Please verify that you will not be violating any local or state laws or regulations by possessing this kit before you order this kit.
