Gravity-Inquiry

 Gravity

For Inquiry I have chosen to learn about Gravity. Me and Nevaeh have decided to work together. We have decided to make 1 news report and 2 models. 3 things we have learnt are:

1) Gravity is made of quantum particals.

2) Gravity has been the weakest force scientists have known about for 1 or 2 years

3) Dwarf means no gravity. That is why dwarf planets don't have gravity.

Our models have 2 planets. One dwarf and one real planet. The dwarf planet has no gravity because dwarf planets are not spheres. Nevaehs one is a bit bigger but mine includes more facts. Here is a photo of us with our models-

Here is a link to our slideshow with all our facts on it

Sun And Us Explination Plan

 Did you know the sun can be harmful to plants,animals and humans in lots of different ways! Yeah and have you ever thought that the sun can make lots of spots in the world even where you live into desserts. If you want to find out more about the sun read my story  about the sun and us.:)

Droughts can cause Crops and plants to die and Greenhouse gases

Deserts can form because of all the heat and plants can not grow because of the heat.Farmers will have to kill their animals because they would not survive either way. Droughts can be in one place at a time for about 10 years!!!

The sun can cause carcinoma and melanoma,the deadliest skin cancer even with layers of sunscreen on.The sun can cause changes to the skin cells structure. They can appear as small spots.

With sunscreen on you can still get sunburn. The heat from the sun will dry out the sunscreen and get to your skin.Long sessions without sunscreen in the sun can cause second degree burns and blistering.

Energy is absorbed through chlorophyll which is the chemical that gives plants their green colour. Any energy not required by the plant is stored in fruit, leaves and roots which in turn gives people and animals energy when they consume plants for food.

 

Photosynthesis is the process that plants use. It has 3 ingredients: water, carbon dioxide and sunlight. During the process, which occurs in the plants leaves, oxygen is released into the atmosphere and glucose is formed which plants use for food. Plants obsorbe carbon dioxide from the air and release oxygen back into the environment.

Without the sun stimulating Vitamin D in both humans and animals it would be impossible for earth to contain life. Vitamin D can also be in plants to help them live. It is provided from the energy of the sun and when it is inside a human or animal they get more energy. It can protect you from a variety of diseases
