What is the difference between the Ascension and the Resurrection?
The Resurrection is when Jesus came back to life as a human, you could touch him, talk to him, and he could talk, and he could touch others as well.
Forty days later, that's when Jesus ascended into Heaven, you couldn't touch him anymore, but you could still talk to him through prayer.
Happily, the disciples talked to Jesus after he resurrected, but they were pretty sad to see Jesus ascend into heaven.
