Grade 3: Living Things Breathe!!<br />
Students detected variation in<br />
Carbon dioxide level using Sensor<br />
after different physical activities.<br />
They understood living things<br />
breathe in and out. Also, they<br />
observed variation in Carbon dioxide<br />
level by comparing 4 digit number<br />

sequence arranging the values in<br />
descending order.<br />
Grade 4: Stick to Your Roots<br />

measure circumference of the bark<br />
of a tree using DBH (diameters at<br />

approximate age of the tree.<br />
Grade 5: Soil & Water Erosion<br />
Students investigated how<br />
different factors in the nature<br />
causing soil erosion and what can<br />
we do to stop it. They did<br />
