Project experamenting

Today me and Paige did our summary for our project. 


Bath bomb research

Ingredients:
1 cup Citric acid ($2.80 1kg)
2 cups baking soda ($9.00 400g x3)
20-30 drops Essential oil ($3.00 750ml)

Our summary
Bath bombs are very relaxing to sit in. The bath bombs will make your skin very soft after your bath because it contains essential oil. When you put a bath bomb in the warm water a chemical reaction occurs. The citric acid and the warm water makes a reaction and makes the bath bomb very fizzy and colorful from the food coloring. It also smells nice if there is peppermint essence or vanilla essence. Bath bombs are also relaxing when you can see and smell the bath bomb. It is also really fun to look at.

What is a bath bomb?
Bath bombs are designed to take relaxing bath time to a completely new level.  A bath bomb is best described as fireworks for you bath.  You drop the bomb in your warm bath and it will begin to fizz, and bubble with colors and scents of nature.  Some have a little sparkle, some flower petals, and some just plain make you feel and smell good.  All contain natural moisturizers of coconut oil and cocoa butter.  All contain therapeutic essential oils and restorative Epsom salts.

When acids and bases come into contact with one another, a chemical reaction occurs. Follow the instructions below to make a fun bath-time chemical reaction with a Fizzy Bath Bomb. Acids and bases are substances that break down into ions (charged atoms) and other compounds when placed in water. Acids break down into hydrogen ions (H+) and bases break down into hydroxide ions (OH-). Many acids taste and smell sour (like vinegar). Bases often have a bitter, soapy taste (like baking soda). NEVER taste a chemical! If you want to know if something is an acid or a base, you can look on the label, ask an adult, research it on the Internet, or test it with cabbage juice (see the Invisible Ink experiment for details). https://ingeniumcanada.org/scitech/education/try-this-out-incredible-chemical-spectacles-fizzy-bath-bombs.php

Background
Bath bombs can have a wide range of ingredients, including bath salts (which can help sooth muscles), food coloring, fragrances and other components. There are, however, a few key ingredients that most homemade recipes have: baking soda and citric acid. Why is this? When baking soda and citric acid are mixed and are then put in water, they undergo a chemical reaction. The reaction produces lots of bubbles, which you see as the bath bomb dissolves in the water. These bubbles that make the water become so fizzy are made of carbon dioxide gas.

Life cycle

For Immersion today we switched groups. My group went to Felicatys Immersion. We talked about life cycles and plants. We did an activity where we had to sort out pictures that were living and that weren't living. Felicaty  gave us a game to try. Its very challenging. She sent all of us a document of what we can watch and research about. We talked about food chains. Did you know that all the food in the world comes from a seed. Lesson Learning Activities: Follow-up: 1 What is energy Classification: Learn that all things are Living or nonliving Discuss Mnemonics and MRS GREN How classification keys work: Dichotomous key for garden creatures You have filled in your 4 slides about Energy. As you go through the immersions, add in things that you have learned. Living or non-living interactive   Here Using the dichotomous key, classify something in your garden. Use the key to classify an animal you find in the g...

Stain removers

Today for immersion we got into groups of four and we had to bring in things that would stain things and we had to bring stain removers. I brought the lemon as a stain remover. As the stain we use food colouring . We had to put the food colouring  on a type of mateareil . The rest of my group brought the powdered detergent and the vinager . The detergent worked the best out of all of them. But all of them worked. It was really fun to experiment with them.
