Aims:

I want to find out how hot air balloons work and if I can make my own.

Research:

Method:

Equipment:

• Tea candle
• 2x bamboo sticks
• 4x straws
• Medium-sized bin liner

Instructions

1. Sharpen the un sharpen part of your bamboo sticks
2. Take the Tea candle wax out of the tin.
3. Make holes on all the sides of the tin at least 1.5 cm apart.
4. Poke the bamboo sticks in the hole making a plus sign
5. Stab the straw in the middle with the bamboo sticks.

How does elastic energy work?

Aim: 

I want to find out how light energy behaves.

Research:

Method:

Equipment

• Light Box
• Power Pack
• Slit
• Cord

Instructions

1. Get Your Equipment ready.
2. Make sure your switches are off.
3. Plug in your power pack.
4. Plug the light box plugs in the red & black terminals.
5. Start the power pack on 2 Volts.
6. Turn both switches on and slightly turn up the Voltage.
7. Turn it to 8 if you are in a dark spot and 10 if you are near a window.
8. Take a slit and put the end away from the light bulb.
9. Follow the Instructions on the reflection and refraction videos.
10. Once your experiment is finished you CAREFULLY pack up.
11. Make sure you get some photos.

Reflection

Reflection is when light bounces of an object going the same direction as it bounces off. The light that bounces off goes onto another object

Refraction:

Refraction is what happens when light bends as it goes from one thing to another, like from air to water. It’s why things look different in water and why glasses can help us see better. Just think of light changing its path when it goes into different stuff.

How do Fibre optic cables work?

A fiber optic cable is a super-fast and thin cable that sends data using light instead of electricity. It’s great for speedy internet and clear phone calls over long distances. It’s also secure and doesn’t have problems with interference like other cables do.

Aim:

I want to find out how gravity affects an egg.

Research:

Method:

Equipment

• Egg
• Toilet Roll
• Plastic and cardboard Straws
• Padding around the Toilet Roll
• Tape
• Scissors
• Plastic bag
• Paper
• Balloon
• Sharp stick
• Newspaper

Instructions

1. Get your toilet roll and stick plastic straws on one side evenly out.
2. And same on the other side but with cardboard straws.
3. Make sure you tape them all together.
4. The egg is not going to fit in the toilet roll so cut a small line to you can fit it in and then tape it back up.
5. Add another toilet roll at the bottom.
6. Get a balloon and cut the bottom and stretch it until you can fit the bottom of the toilet roll in the balloon.
7. You don’t have to do this but for some reason we put a wooden stick or skier you use to put food or something, put we put it in one of the straws.
8. After that put some news paper down inside the toilet roll.
9. After that take a plastic bag to act like a parachute and type it onto each of the 4 straws.

Newton’s first law of motion:

the various ways motion can be described (words, graphs, diagrams, numbers, etc.) were discussed. In this unit (Newton’s Laws of Motion), the ways in which motion can be explained will be discussed. Isaac Newton (a 17th-century scientist) put forth various laws that explain why objects move (or don’t move) as they do. These three laws have become known as Newton’s three laws of motion. The focus of Lesson 1 is Newton’s first law of motion – sometimes referred to as the late of inertia.

Gravitational Potential Energy;

Gravitational potential energy is the energy something has because it’s lifted up. The higher and heavier it is, the more energy it has. The formula is U = mg, where $m$ is mass, $g$ is gravity, and h is height. It’s all about gravity pulling things and making them have energy due to where they are.

Weight Force:

Weight is the force that makes things feel heavy because of gravity. It’s calculated by multiplying an object’s mass by the acceleration due to gravity ($W=m\times g$). So, weight depends on how much stuff is in the object (mass) and how strong gravity is.
