Some bio-detergents can break down proteins

Experiment : let’s use 2 capsula petri filled with gelatine (made of proteine) and then put some enzymatic detergent in the first and non-enzymatic one in the second. We will observe a “hole “ in the gelatine where the proteins are broke down by the enzymatic detergent

We do an experiment with a few batteries, a little wire, a nail and a little pin. we wrap some of the wire into the nail. When the electric current passes through the wire, we see that an electromagnetic field is formed around the nail. because the nail pulls the pins. If we increase the number of batteries, will it pull stronger? what will be If we increase the number of winding of the wire? we will ask more questions and guess the answers.

And if you already use sea salt or mine? In the era of ubiquitous plastic, it turns out that it can pose a threat to us in the context of nutrition. Each type of salt is formed in water reservoirs whether in modern or prehistoric seas. However, sea salt is the variety that is obtained by evaporating water from the present salt water, which are systematically polluted by us mainly with plastic.

What do we need?

water

Different types of salt: marine, mine ... ..

Dishes

Kettle

Funnel

Women's tights

Microscope, eg USB with the possibility of connecting to a computer

After dissolving two of these types of salt (marine and mine), plastic particles were found in the sea salt, coming from the pollution of sea waters with this substance. So let's stick to the salt from the mine, for example from Wieliczka, of course, not advertising anything here😊

Simple Light Refraction Experiment

- you only need four things:
- a sticky note, a marker, an empty transparent bottle, water

1. Draw two arrows on a sticky note. Make sure that each arrow points in a different direction. Stick the note to a blank wall.
2. Fill up the water bottle.
3. The alternating arrows on the note point to the left and the right; students gradually move the water-filled bottle in front of the sticky note and as the bottle moves in front of the sticky note, something amazing happens: the arrows appear to change direction :)
4. The top arrow, which points to the left, appears to point to the right. And the bottom arrow, which points to the right, appears to point to the left.
5. Move the bottle back to see the arrows return to their original directions.

- we learned that refraction occurs because light bends when it passes through substances, such as water and plastic
- as the light travels through a substance, it becomes concentrated into a focal point, usually near the center; after light passes through the focal point, the rays cross over each other and cause images to appear reversed

Our professor showed us an experiment we could conduct with students, starting with a question: Does ice melt faster if it is covered in black clothes or does it actually stay frozen longer?
To find out, the students can take two bowls with the same amounts of ice cubes of the same sizes and put them on the window sill in the sun. One of the bowls is covered with a black hat, the other one is not. The covered one will melt slower, as the temperature stays rather constant beneath the hat.

One of the simplest practices I propose in class is about yeast nutrition.
First, the students make bread (this step is not obligatory) and observe that in a short time the dough grows a lot. Then we try to answer the question "Why does the bread grow? and we come to the conclusion that the dough contains yeast and this makes the cellular respiration and releases co2.
Next, I introduce you to the material at our disposal (plastic bottles, balloons, water, water heater, flour, sugar, temperature sensor, etc.), and encourage you to ask researchable questions about this process of cell respiration of yeast. Each group asks its own question, and we share them to find out if they are researchable or not. Then each group prepares a hypothesis and an experimental design to test the hypothesis. We put it in common. Each group does their experiment, analyzes the results, and then prepares a poster to explain their research to the other groups.

These activities gave me the idea that I can use “cell” laboratory activity for inquiry teaching in my science classes. I can make student think about differences between animals and plants and make them use microscopes to discover that differences. I can use all materials like, onion, leaves, animal parts, microscopes etc. After they finished to observe we can discuss about their findings and I give them an activity sheet that doesn’t require that things that they need to do step by step. I give enough time to discover cells for students.

With a microwave oven, thermometer, clock and water students can relate the power of the device and the amount of energy

Students can determine the amount of energy transferred to a certain amount of water, by the temperature variation.

They record this variation and the time that the heating lasted.

Knowing these variations can calculate the power of the device and determine the associated error.

2. Resources: various vegetables (from the greenhouse and grown outside), test strips for nitrates. Additional material: nitrate sources, allowed nitrate levels in various vegetables. Investigating which parts of vegetables are found to contain more nitrates, which type of vegetable absorbs the most nitrates, which vegetable - grown in the greenhouse or outdoors - accumulate more nitrates. Impact of excessive nitrate levels on health and the environment.

It would be to repeat this experiment using only the enzymatic detergent, but previously exposed to different conditions:
- Saved in the freezer
- Saved at room temperature
- Stored in an oven, for example at 50-60ºC
- Stored in a oven, for example at 80-90ºC

We made something similar when we analyzed the (bad) effects of household claners on the exposed materials (ceramics, plastics, ecc...).
Students tested at home the products they found at home on a list of fixed different testing materials and found what cleaned what with no adverse effects on the conservation of materials.
Once we analyzed the (chemical) composition we also discussed on the effects of different products (acid, basic solutions) on ecosystems.
It was not an IBSE experience that time, I think I s manage to produce an IBSE one next year.

The aim of the activity was to understand the importance of guarding water. Age of pupils: 10 years. They were researching water consumption in their homes. They tracked the amount of water spent back three months. They had the task of including their household and the whole next month watch for water consumption (to close the water when brushing,...). Next month we compared the amount of water consumed.

Students could also look into enzymes and digestion. For example, students could be introduced to intolerance and given the example of lactose intolerance. Students could identify the enzyme most effective in breaking down lactose. Then once identified they can they investigate factors that affect enzyme activity. They then can suggest the most economical way of producing large volumes of lactose free-milking.

Preparation of house soap
The traditional recipe, the one used by grandparents, describes the process of making "hot" soap, made by boiling, with great care. Here's why you need the recipe for licking home soap recipe.
Ingredients required for the lard soap recipe: 4 kg of pork fat (may be old roasted bacon or any fat), degraded vegetable oil (not to exceed 1/4 of the total weight), a spoonful of kitchen salt (50 g) and 3 l water per kilogram of material, 250-300 g caustic soda.
Method of preparation for licking soap recipe: It is preferable to put 300 g of caustic soda from the beginning since it can no longer be added after the composition has become hot because it melts by reacting violently, producing an explosion and spraying everything around . Caustic soda will be handled with extreme caution: with rubber gloves or with a hand wrapped in a nylon bag, because it touches the skin with burns and frosts (they can be neutralized quickly with a cotton pad with vinegar).

Perfume and soap making in the classroom without using alcohol or harmful chemicals might be implemented using vey simple materials which pupils could find in daily life. For example herbs, spices, flowers and plants, leaves, plant oils which are sold in herb shops. They can produce their own perfume or soap in the classroom. They can slso make their simple home detergents in class
