Combine strawberries, 1 teaspoon agave syrup and lemon juice in a blender. Blend until smooth or a little chunky, if desired. If needed, add drops of water to help blend smooth. Pour strawberry mixture into pop molds about half way. Rinse out blender.
Combine frozen bananas, yogurt, 1 tablespoon sugar and vanilla extract in blender. Blend ingredients until smooth. Add banana mixture to molds until almost full.
Freeze until firm, up to 24 hours.
Remove pops from freezer. Run molds under warm water and thaw for about five minutes. Gently tug on sticks to release pops from mold and serve.
