Watermelon cut outs

  2. Touch – Examine the flesh – what does it feel like when you touch it, poke it, squish it? What is a watermelon made of – can you tell by touching it?
  3. Smell – What does watermelon smell like? Does it make you want to eat it?
  4. Taste – Dive in and eat the watermelon! How does it taste? Why is it so watery? What do the seeds feel like? Does the rind taste different than the fruit?

Plant a seed and watch it grow

Watermelons require a long and warm growing season. It takes 80 days for watermelons seeds to germinate and grow, and the soil needs to be about 70 degrees F or warmer when planted. If your climate allows for it, kids can take the seeds and plant them right into the ground after their sensory experiment. Watch for the plants to crop up in the coming weeks.
