2 lessonsWhat the KG Science course covers
Science starts with the child's own body and five senses, because that is the one piece of nature always available to observe. Animals and their sounds follow, then day and night, the sun and moon, and the parts of a plant.
The KG Science course is two units, taken in order: My Body and Animals and Day, Night and Plants.
There are 4 lessons here and 24 questions in total, roughly 20 minutes of teaching. At this age two or three short sittings a week is plenty, and a child who wants to repeat a lesson is consolidating rather than stalling.
This is where Science starts on the site. Nothing is locked, so if these lessons are easy the next grade is one tap away, and if they are hard the grade below is too.
How Science is taught here
Science is taught as observe, sort, then explain. Children first notice what something does, then group things that behave alike, and only then meet the word that names the rule. The explanation arrives last on purpose, because a definition learned before the observation is just a phrase.
How Science runs from playgroup to Grade 5 sets out the full sequence and where this course sits in it.
Levels and scoring
Each lesson plays at Explorer, Challenger or Champion. Only first-try answers count towards stars, so a retry never inflates a score, and a lesson is mastered at 90 percent at Challenger or above. See how a lesson works for the full explanation.
Questions parents ask
How long does KG Science take?
4 short lessons and 24 questions, roughly 20 minutes in all. There is no schedule to keep and nothing expires, so a few minutes at a time is a perfectly good way to do it.
Is my child old enough for KG Science?
Ages 4 to 5 is the guide, but go by what your child can already do rather than by age. Nothing is locked for a visitor, so trying the level above or below costs nothing and takes one tap.
Is KG Science free?
Yes, and without the usual catch. No account is needed, there is no advertising and there are no in-app purchases. It also works with no connection once the site is added to a home screen, or through the free Android app.
Are there experiments to do at home?
The lessons describe observations a child can make with ordinary household things, but nothing requires equipment, and nothing asks a child to handle anything hot, sharp or chemical.
