Description

Chemical formula equation board

Technical field：

The present invention relates to a kind of new tool of educational training study, is specifically a deck.

Background technology:

Chemistry newly opens subject, wherein chemical formula, the memory of physicochemical properties, the note of chemical equation for middle school's ninth grade Recall for difficult point, emphasis.Form of the invention by the way that every kind of material to be fabricated to board, is played cards by custom rule or by rule The method played card, helps user rapidly to remember the chemical formula of various materials, physicochemical properties, while is remembered by playing card Recall chemical equation.

The content of the invention

The form of board includes plane board（Similar to playing card）, three-dimensional board（Similar to mah-jong pieces）.The content of board is divided into A, B two Version, difference lies in selected board face（That is material）It is different.The material one that the plane board of identical version, three-dimensional board board face represent Cause.It is described as follows：

1. individual board face explanation：

Plane board（Similar to playing card）Board space of planes is larger, reflects picture, chemical formula, element valence, the thing of material The physicochemical properties of matter and relevant partial reaction equation, other white spaces of board face voluntarily fill in other by user Related content, plane board legend are shown in Fig. 1.The specific board of plane board meets personally Fig. 2-Fig. 9.A, B editions individual plane boards are general.

Three-dimensional board（Similar to mah-jong pieces）Board space of planes is smaller, reflects chemical formula, the part physical chemical property of material.It is vertical Body board board space of planes is smaller, it may appear that board face material is identical, but the situation of the distributional statement of property, other are such as in reaction equation Holding needs to strengthen memory in use.The three-dimensional board in only a kind board face is shown in Figure 10-Figure 12, and the three-dimensional board for having 2 kinds of board faces is shown in figure 13rd, Figure 14, the three-dimensional board for having 4 kinds of board faces are shown in Figure 15, Figure 16.A, B editions individual three-dimensional boards are general.

2. the species and quantity explanation of board：

A editions, main to include other key reactions in addition to metathesis reaction, board face species and quantity see the table below.Plane board, stand The board face of body board, number are consistent.

B editions, mainly it see the table below including metathesis reaction, board face species and quantity.Plane board, the board face of three-dimensional board, number are consistent.

Brief description of the drawings

Fig. 1 is plane board legend.

Fig. 2-Fig. 9 is the specific board face of plane board.

Figure 10-Figure 12 is the three-dimensional board in only a kind of board face.

Figure 13, Figure 14 are the three-dimensional board for having 2 kinds of board faces.

Figure 15, Figure 16 are the three-dimensional board for having 4 kinds of board faces.

Embodiment

4 people are generally required to play card.Also can other quantity personnel use, rule voluntarily draft.

1. relational language of playing card

By board：The prerequisite antithetical phrase individually combined during by basic board type winning.

Along son：Three kinds of materials are chosen at left and right sides of from equation altogether, you can composition must not choose material of the same race, no along son Obtain and only chosen from equation left side or right side.Reactant, the product species of equation are more, and the possibility formed along son is got over Greatly.Following table is referred to along sub-instance：

Chemical equation	Along sub-instance	It must not form along son
			A+B=C	ABC（Only this is a kind of）	AAC, BBC, BCC etc.
D=E+F	DEF（Only this is a kind of）	DDE, EEF, DFF etc.
			G+H=J+K	GHJ, GHK, HJK, GJK etc. are a variety of	GGJ, HHK etc.
L+M=N+P+Q	LMN, LMP, MNP, MPQ etc. are a variety of	NPQ, LLP, MPP etc.

Triplet：3 identical boards.Touch out for bright quarter, grab dark quarter in the hand.

Antithetical phrase：Two identical boards.

Eating board：Bridge queen gets in family on finger, and report " eating " person, which takes out two boards of oneself, is added together composition along son, and presses Regulation is bright before vertical board by this secondary board pendulum.

Touch board：Referring to any family and get bridge queen, report " touching " person takes out the antithetical phrase of oneself, is added together the secondary triplet of composition one, It is and by regulation that this secondary board pendulum is bright before vertical board.

Thick stick：Report opens 4 identical boards of thick stick.

Listen board：Only poor required one card can winning state.

Winning：Board profile bar part, reports the behavior of winning as defined in meeting.

Draw it oneself and：Oneself grab into the board into sum, and report winning.

Point and：The board got with other people.

2. the basic board type of winning, it is contemplated that the practicality of study, deepens physicochemical properties and chemical reaction in playing card The memory of equation, it is proposed that selection refers to following rules（Also rule can voluntarily be drafted according to actual）.

A editions winnings：By board（Antithetical phrase）+ combination reaction along son+decomposition reaction along the reaction of son+displacement along son+any along son or Triplet（Thick stick）.

B editions winnings：By board（Antithetical phrase）+ 3 kinds along son（Chosen from following table）+ any along son or triplet（Thick stick）.

3. it is different according to number, it also can voluntarily draft rule and play card.

Claims (6)

1. a kind of board for representing chemical formula, one card represent a kind of material, note is familiar with by working out rule of playing cards and playing card Recall corresponding reaction equation.

2. board according to claim 1, it is characterised in that every board represents a kind of material, the chemistry of marked thereon material The contents such as formula, physicochemical properties and picture.

3. board according to claim 1, it is characterised in that the form of board can be fabricated to plane board（Similar to playing card）With Three-dimensional board（Similar to mah-jong pieces）.

4. board according to claim 2, it is characterised in that the board face of same substance obtains property difference according to material and may lead Cause board face material identical, but content is different.

5. board according to claim 1, it is characterised in that the rule played card is being beaten generally according to being chemical equation Strengthen the memory of chemical equation in board.
