OBSA — Week 7 (Infants): Discovery Days — What Happens When I…?
Our Big Summer Adventure · Week 7 · Infants (0–18 mo)

Week 7 — What Happens When I…?

A gentle "little scientists" week for the babies — objects that answer back. A ball that rolls when you nudge it, a soft rattle that sings when you shake it, a scarf that floats down when you let go. All built on the delighted question every baby is already asking: what happens when I do that… again? Mon Jul 13 – Fri Jul 17.

Read this first

This guide pairs with the Infant Footings Framework and the teacher overview — that's where the four footings and the "menu, not a clock" approach live. This is the menu for the Discovery Days week: a handful of gentle "little scientist" moments you reach for whenever a baby is calm, awake, and curious. This week leans on the Cause & Effect / Agency footing — the thrilled "I did that!" of an action that reliably makes something happen — to match the big kids' predict-test-change-one-thing science week. A baby's whole science is "what happens when I…?": nudge the ball, shake the rattle, drop the scarf — then do it again, on purpose. The games are fresh: rolling balls, a soft shaker, a floaty scarf, and a peek-tube — brand-new, not last week's hiding cloths or moo-drum. No screens in this room, ever — the wonder here is a real object that answers back and a warm adult who names it. No stars, beads, glitter, pom-poms, small balls, or any small parts — large, soft, mouth-safe pieces only, choke-tested (see safety). Offer a moment, follow the baby's lead, repeat the favorites — the repeat is the discovery.

Section 1 · The Overview

Week Snapshot

Theme
Discovery Days — What Happens When I…?, the big kids' "little scientists" week scaled down to gentle cause-and-effect play for babies.
Sensory throughline
Objects that answer back — a ball that rolls when nudged, a soft shaker that sings when shaken, a scarf that floats when dropped, a tube that shows a toy tumble through. Every one gives an instant, legible result, so a baby can do it again, on purpose.
Home footing
Cause & Effect / Agency  the thrilled "I made that happen — again!" — with Attention & Connection (looking back and forth between two effects) and Working-Memory Seeds (remembering what happened last time) riding close behind.
Room
Infants · ages 0–18 months · two sub-bands (younger ~0–8 mo, mobile ~8–18 mo)
Dates
Mon Jul 13 – Fri Jul 17 · a full 5-day week. No closures. Friday the babies get their own gentle corner at the whole-camp Discovery Fair.
Family hook
"Our littlest scientists are discovering that their own actions make things happen — nudge the ball and it rolls, shake the rattle and it sings. When a baby does it again on purpose, that 'I did that!' is the very first seed of goal-directed doing."
Developmental value
Cause-and-effect / agency (the intentional repeat), attention & connection (looking between two results), working-memory seeds (remembering the last try), reaching, grasping, sensory exploration.
The connection
The big kids do real science this week — predict, test, then change one thing and predict again (that flexible "what if?" is cognitive flexibility). The babies pour the footing several floors down: the discovery that my action causes a result, and the first flicker of "what if I change it — do it harder, from higher?" — the same curiosity, at its root.
Read every day · large, mouth-safe, screen-free

Babies explore everything by mouth and this is a hands-on "make it happen" week — so every object here is large, soft, and mouth-safe, and there are no screens anywhere in the room.

  • No screens — none, ever. The discovery in this room is a real object that responds and a warm adult who narrates it. No tablets, phones, or "cause-and-effect" videos — background screens reduce the very back-and-forth this week is built on.
  • No small parts — none. No small balls, marbles, beads, stars, glitter, pom-poms, or feathers. Use only large rolling balls (too big to mouth), a large soft shaker/rattle, big lightweight scarves, and a wide clear peek-tube with a large toy. Choke-test every object; when in doubt, leave it out.
  • Large, soft, or secured only. Balls are big and soft; the shaker is one sealed piece (nothing that can open or leak); scarves are large and breathable (offer one at a time, arm's reach, never over a face). No loose trim or threads to pull and mouth.
  • Washable & clean. Anything that goes in a mouth gets sanitized between babies; no shared mouthed ball, shaker, or scarf.
  • No liquids in this room. The big kids' color-mixing, fizz, and sink-or-float stations are not for infants — no vinegar, no watercolors, no water bins. Our "science" is dry, soft, and mouth-safe.
  • July heat: any outdoor moment happens in the cooler morning only, in shade, with water offered per our infant policy. No midday sun.
  • Arm's reach, always. Constant close supervision; store balls, shakers, scarves, and the tube out of reach between sessions.
  • Licensing wins: match our California Community Care Licensing (Title 22) infant-care rules. Where anything differs, licensing wins — ask a lead if unsure.
Section 2 · The Heart

This Week's Menu of Moments

Six gentle discovery moments, each tagged to the footing it pours. These aren't steps to complete — they're a menu. Reach for one whenever a baby hits a calm-alert window, offer it, and let them tell you how long to stay. Repeat the favorites all week; the repetition is the learning — a baby who does the same thing over and over is running the experiment. New games this week — a rolling ball, a soft shaker, a floaty scarf, and a peek-tube — so the babies get fresh cause-and-effect practice, not a repeat of last week. The last moment is Friday's gentle Discovery Fair corner.

Nudge It & Watch It Go
Cause &
Effect · home

This is the week's home moment. Offer a large, soft ball on the floor and let the baby discover that a nudge makes it roll. The magic isn't the roll — it's the moment they do it again on purpose because they figured out they caused it. That intentional repeat is agency, the very root of "I have a plan and I make it happen." Give a clear, instant result (a ball rolls the second it's touched), then get out of the way and let the baby author it.

Younger (0–8 mo)

Hold a soft ball at their hands or feet; when they bat or kick it and it moves, narrate it — "you moved it!" Pause, and see if they reach to do it again.

Mobile (8–18 mo)

Set the ball just within reach and let them push, chase, and push it again. Roll it slowly back and see if they send it to you — the first turn-taking loop.

You nudged it… and it ROLLED! You did that! Do it again?
EF Research: discovering that your own action reliably makes something happen — and repeating it on purpose — is the seed of goal-directed behavior, the root under all of executive function. Google "contingency learning infant agency means-end."
You'll see it when… a baby nudges the ball, watches it move, then reaches to nudge it again — looking to you, delighted that they made it happen.
🔔
Shake & It Sings
Cause &
Effect

The same "I made that happen" thrill, in sound. Offer a large, sealed soft shaker or rattle — shake it once so they hear it, then hand it over. When the baby shakes and it sings, they've found a result they control with their own hands. Let them repeat it as long as they like; the repeat-with-intent is the whole experiment. Later in the week, offer a shaker that sounds different and watch them notice the change — a first "huh, that's not the same one!"

Younger (0–8 mo)

Guide a hand to the shaker and shake together; pause and see if they wiggle or reach to make the sound come back.

Mobile (8–18 mo)

Let them shake, wave, and bang it to hear the sound change with the motion. Offer a second, different-sounding shaker and name the difference.

You shook it… it SINGS! Listen — you made that sound. Again?
EF Research: objects that give instant, legible feedback let a baby learn "my action = this result," the earliest planning precursor. Physical objects only build this with a responsive adult, never alone. Google "means-end goal-directed action infants."
You'll see it when… a baby shakes on purpose to bring the sound back — or pauses and looks up when a different shaker sounds unexpected.
🧣
Up… and Floating Down
Attention &
Connection

A slow, watchable result — and a first taste of looking from one thing to another. Lift a large light scarf and let it float down; the baby tracks it, then looks to you, then back to the scarf for another. That looking back and forth — scarf, you, scarf — is attention gently shifting between two things, the earliest ground the big kids' "flexible switching" is built on. Follow the baby's gaze first, name what they're watching, and let your warm back-and-forth carry the moment.

Younger (0–8 mo)

Float the scarf slowly down toward them and narrate — "up… and dooown." Their calm tracking of the slow fall is the whole lesson; follow their eyes.

Mobile (8–18 mo)

Let them toss or drop the scarf and watch it float; catch their glance from the scarf to your face and back — name each thing they look to.

Up it goes… and floating… dooown. You're watching it. Now you look at me — should we do it again?
EF Research: following a baby's focus and naming it (serve-and-return) lengthens attention, and looking between two things is the earliest form of shifting attention — the foundation the older rooms' flexibility stands on. Google "serve and return joint attention shifting infants."
You'll see it when… a baby tracks the whole slow float, then looks from the scarf to your face and back — shifting attention between the two on their own.
🔭
Down the Peek-Tube
Working-Memory
Seeds

Cause-and-effect with a memory seed inside it. Drop a large soft toy into a wide clear tube and let the baby watch it tumble down and out the bottom. It disappears into the tube for a beat — then reappears. By midweek, watch a mobile baby look to the bottom, waiting for it, before it comes out: they're holding "it's coming back down there" in mind. That held expectation is a working-memory seed, riding right alongside the "I dropped it and it fell" cause and effect.

Younger (0–8 mo)

Keep it simple and slow — drop the toy so they watch it fall and land; narrate "innn… and out the bottom!" The tracking of the fall is plenty.

Mobile (8–18 mo)

Let them drop the toy in themselves and look to the bottom for it to reappear — then hand it back so they can run the "experiment" again.

In it goes… where did it go? … THERE it is, out the bottom! You made it fall. Again?
EF Research: watching an object disappear and reappear, and anticipating where it comes back, is an early behavioral window into working memory — holding "where it went" in mind. Google "object tracking anticipation working memory infants."
You'll see it when… a baby drops the toy, then looks to the bottom of the tube waiting for it to reappear — holding the outcome in mind.
🎈
What If I Change It?
Cause &
Effect

The baby-sized version of the big kids' "change one thing." Once a mobile baby knows the ball rolls and the shaker sings, gently offer a small variation and let them notice the difference: nudge the ball on the flat mat (rolls a little) then down a low soft ramp (rolls a lot); drop the scarf from low, then from a bit higher; shake softly, then hard. You're not teaching a rule — you're offering the first flicker of "what happens if it's different?" and letting the baby run it. A gentle nod to the big kids changing one variable and predicting again.

Younger (0–8 mo)

Skip the variation — keep the plain, reliable version (one soft roll, one gentle shake). Sameness is what this age needs; the "change it" move is for the mobile babies.

Mobile (8–18 mo)

Offer the same object two ways — flat then down a low ramp, soft then firm — and narrate the difference. Let them choose and repeat whichever result delights them.

On the flat it rolls a little… down the ramp it rolls FAST! You changed it — what happened?
EF Research: noticing that a changed action gives a changed result is the earliest root of flexible "what if?" thinking — the same curiosity that becomes real cognitive flexibility in the older rooms. Google "infant exploration variation causal learning."
You'll see it when… a mobile baby tries the object one way, then the other, and reacts to the difference — a bigger grin, a surprised look, a deliberate repeat of the "faster" way.

Our Little Discovery Corner (Friday only)
Cause &
Effect · fair

Friday's gentle highlight. When the whole camp holds its Discovery Fair, our babies get their own calm corner too. There's nothing new to perform — this is simply the week's favorite moment, offered to a baby held by (or sitting with) a parent or teacher, so the grown-up gets to see the discovery the baby's been running all week: the nudge-and-roll, the shake-and-sing, the drop-down-the-tube. If a parent visits, hand them the ball and let them roll it back to their baby. Frame it honestly for yourself: we're showing a footing being poured — the delight of "I made that happen" — not claiming the baby now "has" a science skill. Keep it short, calm, and joyful.

Younger (0–8 mo)

Held close, a quiet round of the floaty scarf or a soft shake — the calm shared watching is the whole "fair" at this age. No crowd, no rush.

Mobile (8–18 mo)

Set out the ball, shaker, and tube and let the baby show a grown-up their favorite — nudging, shaking, dropping — repeating the discovery they own.

Show grandma what you found out this week… you nudge it… and it ROLLS! You did that!
EF Research: repeating a self-caused result on purpose is the milestone of early agency — the seed of goal-directed doing. A parent watching that repeat is watching the footing itself. Google "infant agency goal-directed behavior development."
Keep it calm: the fair is busy — protect the babies from the crowd and noise with a settled, separate corner and normal ratio; a fussy or tired baby skips the fair and keeps their own quiet routine. No baby is required to "perform." Same large, mouth-safe objects; sanitize between babies; arm's reach throughout.
⭐ Teacher Move · one this week

Show it once, then hand it over — and wait. On the home moment (Nudge It & Watch It Go), do it the master-teacher way: first you nudge the ball once or twice so the baby sees the "touch → it rolls" happen; then do it together, your hand gently guiding theirs; then let go and pause — don't fill the silence, don't do it for them. Give the baby the room to reach out and cause the roll themselves. That hand-off — from you, to together, to them — plus the patience to wait, is what turns "a toy the teacher rolls" into "a thing I can make happen." The same show-then-step-back works on the shaker and the peek-tube.

Section 3 · The Week, Loosely

How the Week Drifts Along

Not a schedule — just a gentle drift as babies grow familiar with the objects that answer back, and slowly start to change what they do to see what changes. The week runs Monday through Friday, with a calm Discovery Fair corner on Friday. Every moment is fair game any day; this is only a soft suggestion. Keep following each baby's body clock first.

Mon · 7/13
Meet the objects that answer

Gentle first exploring. Let babies discover the soft balls, the shaker, and the scarf — grasp, mouth-safe, watch what each one does. Your job is warmth, narration, and being close.

The Infant Discovery Corner

The whole camp holds its Discovery Fair on Friday, and every room shares its week — including the babies. Our part is brief and calm, tucked into a settled spot away from the busy stations: a small corner where one or two babies at a time, held by or sitting with a grown-up, simply do the thing they've practiced all week. The goal is a few joyful seconds of "look what I found out" — nudge the ball, shake the shaker, drop it down the tube — not a performance or a long visit.

One shared moment to offer: set out the week's favorite objects and let the baby show a parent or teacher their discovery — "watch what happens when I nudge it… it ROLLS!" If a family stops by, hand them the ball and let them roll it back to their baby, so the grown-up gets to see the "I did that!" up close. Frame it honestly: this is a footing being poured — the delight of a self-caused result — not a claimed science skill.

Keep-it-gentle rail — read before it runs

  • Protect from the crowd. The fair is loud and busy; our corner is settled, shaded from the bustle, and separate. A tired, hungry, or fussy baby skips the fair and keeps their normal quiet routine — no baby is required to take part.
  • Same materials, same rules. Only the week's large, soft, mouth-safe objects — no small parts, no liquids, no screens. Choke-tested; sanitized between babies.
  • Arm's reach, normal ratio. Confirm the infant-room ratio holds through the fair window; a lead is present. Babies are held or seated close, never set loose in the crowd.
  • Invite families gently. If a parent visits, hand them the object and let them share the moment with their baby — warm and unhurried, not staged.
  • Heat & weather: if any part is outdoors, it's the cool morning window, shaded, water per infant policy. Keep babies comfortable and unhurried either way.
  • Honest framing: we're showing the footing — "I made that happen" — being poured, not claiming a measured skill. Warmth over performance, every time.

Section 5 · Prep

Before the Week

A calm, ready room makes a gentle week. Set these over the weekend or Monday morning — and choke-test every object before it reaches a baby.

Large soft rolling balls
Big, soft, lightweight balls — too large to mouth, no small/hard balls or marbles. Choke-test each one and check for loose parts.
Sealed soft shakers / rattles
Large one-piece shakers that can't open or leak; a couple with different sounds for the "notice the change" moment. No beads that could spill.
Large lightweight scarves
Big, breathable scarves for the float-down moment — offer one at a time, arm's reach, never over a baby's face.
Wide clear peek-tube + large toy
A wide, clear tube (short and sturdy) with a large soft toy that tumbles through — the toy too big to mouth, the tube with no small parts.
Low soft ramp / wedge
A gentle padded ramp or wedge for the Thursday "change one thing" roll — soft edges, low angle, nothing to tip or pinch.
Screen-free check
Confirm no tablets, phones, or "cause-and-effect" videos are used as activities in this room this week — real objects and warm narration only.
Plan the Friday discovery corner
Confirm the room's fair window, a calm separate spot away from the crowd, extra hands for arm's-reach ratio, and a quiet-routine plan for babies who skip it.
Sanitizing supplies
Wash and sanitize balls, shakers, scarves, tube, and toys between babies — plan the clean-between-children routine.
Confirm Title 22 + heat plan
Check infant supervision and material rules with a lead; any outdoor time is cooler-morning only, shade and water per policy. Licensing wins.
Choke-test everything
Run every object through the choke-test tube before it goes on the floor; anything that fits, or has a removable/small part, stays out.
