Nutrition Box Activity

 

A nutrition box activity, often used in schools, educates children on healthy eating by having them sort, create, or pack balanced meals. Activities include building a "food rainbow," packing lunches with fruits, veggies, and proteins, and using cut-out activities to teach about nutritional food groups.

Students pack a healthy lunch and spoke briefly about the nutrients, it helped boosting confidence and promoting healthy choices.

Class VII measuring lung volume activity

 

Measuring lung volume (specifically vital capacity) can be done using a DIY water displacement experiment. By exhaling into a submerged, water-filled jug, the air displaces water, allowing you to measure your maximum breath volume in a container. 

Water Displacement Method (DIY)

1. Prepare the Setup: Fill a large plastic container with roughly 4 inches of water.
2. Fill the Jug: Fill a clear, large (e.g., 1-gallon) plastic jug completely with water.
3. Submerge the Jug: Place your hand over the opening of the jug and carefully turn it upside down, submerging the opening into the container's water without letting air in.
4. Insert Tube: Work a plastic tube or straw under the mouth of the jug.
5. Exhale: Take a deep breath and exhale as much air as possible through the tube, causing air to replace the water in the jug.
6. Measure: Mark the water level with a permanent marker. Re-fill the container to that line with a measuring cup to determine your total lung capacity in milliliters.

The activity was interesting and students understand lung volume measurement in a good way.
