DEDICATION For Zak, Sydney, Hannah and Charlie xxx Get ready to shriek and squeal all the way through this bone-chillingly gruesome book. Make and pick fake scabs, create a blood bath, drink a blood cocktail and dissect a brain.

Test your surgical skills by cutting open a fake stomach, and try to identify healthy urine through taste yuck! If youre after something a bit more lighthearted, try making fake vomit, sticky poo or a bug-filled bath bomb. Find out why saliva is super and how it impacts taste, then create the most revolting food combination you can imagine. If smells are more your thing, there are eggs, farts, stinky wee and even cow burps in the chapter. Learn all about bugs by making a worm hotel, a bug restaurant and a real slime trail, or take a journey back in time to experiment with mummification, plastic milk and different kinds of toilet paper. Find out about disgusting diseases and the grossest things humans have done throughout history with these deliciously horrible experiments. You might get a bit sticky, slimy and dirty, but thats the best kind of science, right? Many of the projects in the book are open-ended and have ideas for further exploration on the topic.

Dont be limited by the ideas in the book either. Tinkering, improving designs and generally having fun with materials are whats most important.

Follow the instructions! Read through the instructions first, and if youre not sure about something or need to use a heat source, ask an adult for help. If youre the adult reading this, choose projects you think your child can do safely alone, or plan to work together with them on the more difficult ones. Dont eat or drink any experiments unless the activity says youll be creating something edible, and if youre out and about, never assume any poo is the delicious edible kind thats . Look after your eyes and clothes.

Remember, food coloring can stain clothes and furniture, and slime can be tricky to remove too! Look after animals. I promise no animals were harmed in the making of this book, and I expect the same consideration from YOU! Remember that worms and bugs are super helpful to our planet and we NEED them! Always ask an adult before starting an experiment. The final productwhere there is onedoesnt have to look perfect, and its totally fine to make a mistake along the way. Who knows, you might end up with an even better creation or investigation. Dont forget to clean up after youre finished, especially if youve made a mess. Your parents will thank you!

People tend to use the word experiment in a very general way, but a real experiment has a specific format that follows the scientific method.

You need to ask questions, come up with a hypothesis, or prediction, and set up an investigation, usually changing only one variable. When a real scientist has finished experimenting, they analyze the results and form a conclusion. Phew! It sounds complicated but really isnt. Check out the Toilet Paper Testing experiment to find out more. The best way to conduct science activities is to watch what happens, predict what will happen next, observe what happens next and then explain why it happened. ASK QUESTIONS If youre a child, ask your adult or helper questions.

You might be able to teach them something new. If youre the adult, asking simple questions about the activity youve just done is a great way to see if the child understands what has happened. Encourage them to ask questions too, as a question can often lead to a whole new activity. EXTEND THE LEARNING Once youve finished an activity, the learning can be extended in lots of fun ways: MAKE AN ANNOTATED DRAWING Draw what happened and label it. Showing the drawing to friends and family can be a great opportunity to share your knowledge with others. TURN IT INTO A STORY Once upon a time, two children walking in the woods came across a frozen gelatin brain in the water.

It didnt look real. Was it a trick? You get the idea!

Ancient Egyptians used brains to cure eye infections and pulled them out through the nose with a hook. Aristotle thought the brain was for cooling the blood, and Einsteins brain was smaller than average. The brain is a truly incredible organ that stores memories and controls how we think and react to the environment around us. The human brain contains billions of nerve cells and weighs around 3 pounds (1.4 kg). Blood makes up around 7 percent of the weight of a human body and contains red blood cells, white blood cells and platelets.
