Seeing a trend in my SPSS T-tests, is this normal?

#1
Hello all. While attempting to complete my homework for my Stats class on SPSS I noticed on 3 out of the 4 problems I've done so far, I have gotten .000 for the p-value. Two were Independent T-tests and the other was a One-sample T-test. Is there something that I'm missing or could be entering incorrectly on SPSS? I know it .000 means it's just rounded but I thought it was odd it's happening so frequently. If it contines to happen I'll email the professor but I won't get a response until tomorrow morning, so I was looking for opinions on here.
I'll attach pics of the tests I have and maybe that will help. Thanks!

Why do you think it's odd? If a mean difference to be tested is
> 1 SD and the sample size is'nt too tiny, as both is the case here,
then p < 0.001 .

With kind regards
