Next to selecting a microscope, a balance is the largest science equipment purchase decision that most schools and homeschool families make.
Watch this video to learn more about digital balances:
The type of balance you choose may depend on the age of your children and which science curriculum you're using. Below are some of your options for the primary and high school grades.
Balances for the Primary Grades:
In the elementary grades, the primary double-pan balance, with 1 gram sensitivity, is ideal. This balance helps children clearly visualize the concept of "equal mass." (You'll need to purchase a mass set of some type with this balance.) The double-pan school balance is another good option. It has more accurate 0.5 gram sensitivity and comes with an 8-piece mass set.
Digital scales are an easy-to-use option, although your children will not see how "equal mass" (when the pans balance) works. The 2000 g digital balance is the best all-around choice. It has a high capacity (2000 grams) and is accurate to 0.1 gram.
A simple spring scale or platform scale will also work for many needs, although the sensitivity of these scales is weak compared to a balance. Use a plastic bag to hang an object from the hook of a spring scale in order to weigh it.
Balances for High School:
For high school chemistry, a balance with sensitivity of 0.1 gram or
0.01 gram is needed to weigh chemicals. A less sensitive balance, like those listed
above, is usually adequate for most other high school
applications (such as physics).
