27. Sink or Float
This is one of the easiest science activities that makes understanding buoyancy easy.
What you will need:
- 2 Oranges
- Glass vase
How to do it:
Fill the vase three-fourths with water. Let your preschooler peel an orange (great for motor skills!) and drop it into the vessel. The peeled orange will sink to the bottom.
Next, ask them to drop an unpeeled orange in the vase. This orange will float.
By common logic, unpeeled orange should float, as it is lighter! But in this case, it is the lighter object that sinks! Can your kids (or you!) guess why?
Orange peel is porous and packs in many air pockets, which give it the necessary upthrust to make it float. When the orange is peeled, these air pockets are removed thus sinking a peeled orange.

This is a hands-on experiment to teach kids how climate change is impacting habitats of some of their favourite animals including penguins, polar bears and seals to name a few.
What you will need:
Clay/ Animal figurines of Seal or Bear or Penguin
Blue Food Colouring
How to do it
Step 1: Pour water on the plate and set it in the freezer to get a sheet of ice.
Step 2: Use clay to make a seal or a polar bear if you don’t have their animal figurines.
Step 3: Take out the ice sheet from the plate by pouring warm water on the back of the plate. This will be your sea ice.
Step 4: Pour water in the plastic box till its half full. Add blue food colouring to make it look like sea water.
Step 5: Place the ice sheet in the plastic box.
Step 6: Position your animals (we used a Penguin) on the ice sheet.
Step 7: Take the assembly and place it outdoors in a sunny spot.
You will observe as the time passes, the ice sheet starts to melt gradually. Thus, decreasing the area (habitat) for your animal to live on.
This is exactly what is happening at the poles. Polar Ice is gradually melting due to global warming, thus, destroying the habitat of polar animals.
