My grade went on a field trip to the Museum of Natural Science in Raleigh. We got to see snakes, lizards, fish, and an exhibit about race. the first area that we went to was the forest section. in the forest section you were able to see all sorts of wild life including snakes, fish, salamanders, and birds. The next section that we went to was the minerals section. The section was about all of the rocks and minerals that are under the soil in North Carolina. The next section was the space section were there were a lot of cool objects from space.

After we explored a little bit we had lunch outside. The outside is awesome because there is a giant globe.

The next section that we went to was the race section and that was the main reason that we went. It was on the 4th level, once we got there our teachers handed out sheets of paper for us to fill out about the section. It was a really cool experience going to the race exhibit.

Overall the field trip was very fun and I learned a lot about people, animals and space. I hope that you are able to go and visit this amazing museum.

Hello, and today I will talk about how I made a working heat shield with every day materials. Are space agency name is Big Boy’s space agency. We had vey strict rules for designing are heat shield. It had to be 1 cm or less and it had to weigh 42 grams or less and you could only use a limited amount of supply’s.

My heat shield weighed 21 grams and was less than 1 cm. It was made out of tin foil, metal lathe, lasagna, Duck tape and a sponge. How we decided to use and order these materials is through tests. The first test that we ran was with tin foil and metal lathe. we use a heat gun that got up to 572 degrees Fahrenheit. In the photo you can see the hot and cold side temperature for a minute. As you can see these materials were very good.

This test was about finding good materials that will protect the front of the heat shield. These materials are good conductors.

Are second test is about fining a good insulator. So we used a sponge and spackaling compound to make a good insulator.

As you can see the hot side of the insulator was very hot and that the cold side stayed ok.

Now that my group had found to good ideas to use we combined them to make are heat shield

Our heat shield is made of tin foil, metal lathe, lasagna, duck tape and a sponge. Our heat shield had to survive a blow torch.

I the end our heat shield survived and was the lightest so we won for our class.
