Diane began working on her lamp project by cutting out the top and bottom circles using a compass and bend saw. She found the bend saw to be a very efficient tool for cutting circles. However, the bend saw later broke down, forcing her to use alternative tools like a jig saw and coping saw to cut out the legs and slots. She documented her progress, including smoothing edges with a disc sander and drill press. Diane assembled the legs and top piece to test the fit of the slots but realized she needs to cut a hole in the center of the top piece to change the bulb.
草稿
Diane Guo wrote an essay discussing the costs and ethical issues related to space exploration. Space exploration requires high technology and large financial investments, such as the $109 billion spent on the Apollo program. However, critics argue that the money spent on space could be better used to address problems on Earth like providing clean water and food for those in need. Space exploration can also negatively impact the environment through rocket exhaust and the accumulation of space junk. While it provides some benefits, countries should reduce spending on space and instead focus on developing technologies that directly improve life on Earth.
Mission to mars
Diane Guo designed a space shuttle for a mission to Mars. The shuttle is cone-shaped to reduce atmospheric resistance. It will be made of titanium, a hard material that can withstand heat. To land, the shuttle will use parachutes at 10km above Earth and a rudder, wheels, and speed brakes. It will carry two astronauts, 400kg of food, oxygen, nitrogen and water produced from fuel cells. The shuttle will use rockets and engines fueled by hydrazine to overcome Earth's gravity and reach Mars after approximately 164 days.

The document discusses whether multimedia violence is a problem for children. It notes that children watch an average of 7 hours and 38 minutes of television per day, where it is impossible to avoid violent scenes. While some argue that media violence does not make children more aggressive, the document asserts that extensive exposure to violence can desensitize children to violence and make them more likely to see violence as a way to solve problems. It concludes that multimedia violence does have negative impacts on children's behaviors and can lead to increased real-life violence.

The document summarizes the process of cutting front and back triangles for a woodworking project. The author used a pull saw to cut the triangles because it could reach all the way through and was faster than a tenon saw. They made a mistake by cutting at an angle instead of keeping the cut perpendicular to the workbench, resulting in an uneven cut. They plan to sand the edges of the triangles to make them even before measuring and marking the next steps of the project.
Tomorrow when the war began
The book "Tomorrow When the War Began" by John Marsden is about a group of teenagers who go on a camping trip and return home to find that their country has been invaded. They become guerilla fighters to rescue their families and fight for their survival. Throughout the story, the characters are forced to do things they never imagined, like killing others, in order to survive in the war. One character, Ellie, sets a garden on fire and kills three soldiers who were chasing her friends in order to save themselves. Surviving the war requires the characters to do extreme acts, even if they are bad, to stay alive against the invading forces.
User trail of the moving toy
The document summarizes observations from a user trial of a moving toy with kindergarten children ages 3-4. The children were able to identify the toy animals and played with the toys in creative ways, such as pretending the spring was a guitar. However, some children pulled the springs too hard in a way that could hurt others. Based on the children's engagement and requests to buy the toys, the trial suggests the toys were generally a success, but that safety instructions may need to be provided.

The move it project evaluation
The student created a moving toy project of a chick hanging from a palm tree. While the overall design matched the intended concept, the palm leaves were sharp and took a long time to cut out. For future projects, the student would simplify the design and choose harder woods to allow for better movement. The spring was also too small and did not allow for much bouncing. Some redesign is needed to make the toy safer and bounce more for the intended younger age range.
