1. The roofing crew arrived at the house early in the morning. It was going to be a hot day and they wanted to get as much work done as possible before the sun beat down. The first thing they did was start prying off the old shingles. When some areas were cleared off part of the crew rolled the new roofing felt in place. Then flashing and drip edge were applied on top. Then before the old roof was off, the new one was being put down in place, starting along the lowest edge of the roof.

2. In summer, a blue whale goes north to feed. There, the blue whale eats and eats. It eats tiny sea creatures called krill. The blue whale uses its baleen plates to eat. First the whale opens its mouth. Then water flows through, but the krill are caught in the baleen plates. In one day, a blue whale takes lots of huge gulps of krill. It takes lots of krill to fill up a stomach that holds about a ton! Every day in the summer, the whale has more meals of krill. The whale eats enough krill to give it energy for all year. It stores the extra energy in its blubber. Then in winter, the blue whale does not eat much at all. It lives on its stored energy.
