Pre-readers are independent
Every line is spoken and captioned. Children don't need you to read the instructions.
For teachers, co-ops and tutors
Science centers that run themselves
A narrator guides every child through a real investigation, so a science center works even when half the class can't read yet. Launch on the big screen, explore on tablets, then try it for real.
In your week
One lab, four ways in.
- 1
Launch together
Open the lab on the classroom screen. Children call out their guesses before anyone taps.
- 2
Explore at a center
Pairs run the lab on a tablet or Chromebook. Headphones help; the captions show every line too.
- 3
Try it for real
Each lab's grown-ups page has a hands-on version with ordinary materials: ramps, ice cubes, bean seeds.
- 4
Record and share
Print the lab record or the certificate for portfolios, or use the talk-about-it questions in circle time.
Alignment
NGSS* Kindergarten, lab by lab.
Each lab targets one performance expectation and the science and engineering practice it names.
| Standard | Lab | What it covers | Practice |
|---|---|---|---|
| K-PS2-1* | Push the Ball! Free | Children plan and carry out a simple investigation comparing what pushes of different strengths and different directions do to an object's motion. | Planning and Carrying Out Investigations |
| K-PS2-2* | Ramps & Bumpers | Children look at what happened to decide whether a design, like a ramp or a bumper, does what it was meant to do: change an object's speed or direction. | Analyzing and Interpreting Data |
| K-PS3-1* | Sun & Shade | Children make observations to find out what sunlight does to Earth's surface (sand, soil, rocks and water). Temperature stays relative: cooler, warmer, hot. No numbers. | Planning and Carrying Out Investigations |
| K-PS3-2* | Shade Builders | Children use tools and materials to design and build a structure (like an umbrella, canopy or tent) that reduces the warming effect of sunlight on an area. | Constructing Explanations and Designing Solutions |
| K-LS1-1* | What Living Things Need | Children use observations to describe patterns in what plants and animals (including people) need to survive: plants need light and water, animals take in food, and all living things need water. | Analyzing and Interpreting Data |
| K-ESS3-1* | Habitat Match-Up | Children use a model to show how the needs of different plants and animals (including people) relate to the places they live. For example, deer eat buds and leaves, so they usually live in forests; grasses need sunlight, so they often grow in meadows. | Developing and Using Models |
| K-ESS2-1* | Weather Watchers | Children use and share observations of local weather to describe patterns over time, such as counting sunny, cloudy, rainy and windy days, or noticing that mornings are usually cooler than afternoons. Counts are whole numbers; temperature is only warmer or cooler. | Analyzing and Interpreting Data |
| K-ESS2-2* | Nature Detectives | Children construct an argument, supported by evidence, for how plants and animals (including people) can change their environment to meet their needs. | Engaging in Argument from Evidence |
Why it works in class
Less setup, more science.
Whatever devices you have
iPads, Chromebooks, Windows, Mac and interactive whiteboards - in the browser, nothing to install. Patchy Wi-Fi? The free Chrome extension runs offline.
No student data
No logins, no accounts, no tracking. Nothing a child does leaves the device.
Fits a center rotation
Each lab takes 10 to 15 minutes, and children can restart or stop any time.
Evidence of learning
A printable lab record per lab, and a certificate when all eight are done.
Low risk
A one-time purchase with a 30-day refund. No subscription to cancel.
