E IS FOR EX­PER­I­MENT These en­gag­ing ac­tiv­i­ties will fas­ci­nate your preschooler and teach use­ful con­cepts for pri­mary school, too.

Who says preschool­ers are too young for sci­ence? These en­gag­ing ac­tiv­i­ties will fas­ci­nate them and teach them use­ful con­cepts for pri­mary school, too.

Kids in Sin­ga­pore start for­mal sci­ence les­sons only in Pri­mary 3, but there’s so much you can do with your preschooler be­fore that.

In­tro­duce your lit­tle one to sci­en­tific con­cepts in a safe and fun way with these cool ac­tiv­i­ties from Amy Lim, se­nior prin­ci­pal at Kin­der­land (Yio Chu Kang).

BUB­BLES

WHAT TO DO Make your own bub­ble so­lu­tion with dish­wash­ing de­ter­gent and wa­ter. Cre­ate bub­bles us­ing straws or pipe clean­ers as bub­ble wands.

Now try mak­ing new bub­bles by adding glyc­er­ine, corn syrup or vine­gar to the soap so­lu­tion. Which in­gre­di­ent makes longer­last­ing bub­bles?

CON­CEPTS YOUR KID LEARNS Chem­istry, sur­face ten­sion. FUN FACT The se­cret to mak­ing bub­bles is sur­face ten­sion. Adding soap to wa­ter changes the sur­face ten­sion, cre­at­ing bub­bles. When glyc­er­ine, corn syrup or vine­gar is added to the same wa­ter, it low­ers the sur­face ten­sion, so bub­bles last longer.

WA­TER PLAY

WHAT TO DO Do dif­fer­ent ac­tiv­i­ties with wa­ter, such as fill­ing up con­tain­ers of dif­fer­ent sizes.

Ask your child open-ended ques­tions on mea­sure­ment, weight and vol­ume.

These help pro­mote pre­dict­ing skills and sharpen prob­lem-solv­ing abil­i­ties. CON­CEPTS YOUR KID LEARNS Mea­sure­ment, weight, vol­ume. FUN FACT Weight is the force on an ob­ject due to grav­ity. Vol­ume is the space an ob­ject or sub­stance oc­cu­pies, mea­sured in litres and millil­itres. The same vol­ume of two dif­fer­ent sub­stances may have dif­fer­ent weight.

SEE­SAW

WHAT TO DO Cre­ate a see­saw with a ruler as the plane and a toi­let roll as ful­crum. Bal­ance the plane with equal weight on both ends.

Then, move the ful­crum to ei­ther end of the plane. Can you bal­ance the plane as you did ear­lier, with ma­te­ri­als of dif­fer­ent mass?

CON­CEPTS YOUR KID LEARNS Force, mo­tion.

FUN FACT The lever is one of the six sim­ple ma­chines, which helps lift heavy ob­jects with less ef­fort.

There are three classes of lev­ers: A see­saw is a first-class lever; a wheel­bar­row is sec­ond, while tongs are third.

CHECK­LIST

WHAT TO DO Write a list of tasks on blank cards. Group them un­der a “To do” list. Use vo­cab­u­lary such as “mea­sure”, “ob­serve” and “ex­per­i­ment” to de­fine the ac­tions that your child needs to per­form.

A younger child can cre­ate cards with il­lus­tra­tions and words to as­sist with word recog­ni­tion. CON­CEPTS YOUR KID LEARNS Pic­ture-text as­so­ci­a­tion, read­ing, writ­ing.

FUN FACT These cards can dou­ble as flash cards for words or sen­tence for­ma­tion games. Flash cards are a handy re­source and a great way to present, prac­tise and re­cy­cle vo­cab­u­lary.

RAMP

WHAT TO DO Cre­ate dif­fer­ent kinds of ramps with drops, hills, jumps and loops by us­ing toi­let rolls, card­board, tis­sue boxes and a pair of scis­sors.

Place a mar­ble or ta­ble ten­nis ball on the ramp. Did the mar­ble or ball travel faster as it went far­ther down the ramp?

CON­CEPTS YOUR KID LEARNS In­clined planes, speed, weight, shapes.

FUN FACT The in­clined plane is one of six sim­ple ma­chines. An in­clined plane makes it eas­ier to raise some­thing heavy, such as a rock. In­stead of lift­ing the rock straight up, you can raise it from its orig­i­nal lo­ca­tion with less force by push­ing it up a ramp.

MAR­BLING

WHAT TO DO Mix pow­der paint with some oil. Drop the mix­ture into a tray of wa­ter. Ob­serve how the paint stays afloat on the wa­ter.

Mix in oil paint of dif­fer­ent colours and ob­serve the change. When done, place a piece of draw­ing pa­per on the wa­ter sur­face and then re­move it to un­veil a piece of art. CON­CEPTS YOUR KID LEARNS Chem­istry, liq­uids, prop­er­ties of ma­te­ri­als.

FUN FACT Wa­ter and oil do not mix be­cause they have dif­fer­ent den­si­ties. Den­sity is a mea­sure­ment of how solid some­thing is.

Oil is less dense than wa­ter so it floats on wa­ter.

MAR­BLE MAZE

WHAT TO DO Tape straws or card­board cutouts onto a box lid to cre­ate a maze. Have your child plot two or more paths through the maze. Cre­ate a “start” and a “fin­ish” point.

Drop a mar­ble ball into the maze, then lift and tilt at any an­gle to guide the mar­ble to the “fin­ish” point within the short­est time.

CON­CEPTS YOUR KID LEARNS 3D ob­jects, mea­sure­ment, spa­tial aware­ness.

FUN FACT Mak­ing a mar­ble maze pro­motes spa­tial un­der­stand­ing and aware­ness in a child. It helps her de­velop an or­gan­ised knowl­edge of ob­jects in re­la­tion to her­self in a given space. The fun is end­less with mar­ble maze.
